Grinding/cutting/drilling of masonry, concrete, metal andother materials with silica in their composition may giveoff dust or mists containing crystalline silica. Silica is abasic component of sand, quartz, brick clay, granite andnumerous other minerals and rocks. Repeated and/orsubstantial inhalation of airborne crystalline silica cancause serious or fatal respiratory diseases, includingsilicosis. In addition, California and some otherauthorities have listed respirable crystalline silica as asubstance known to cause cancer. When cutting suchmaterials, always follow the respiratory precautionsmentioned above.

WARNING

Grinding/cutting/drilling of masonry, concrete, metal andother materials can generate dust, mists and fumescontaining chemicals known to cause serious or fatalinjury or illness, such as respiratory disease, cancer,birth defects or other reproductive harm. If you areunfamiliar with the risks associated with the particularprocess and/or material being cut or the composition ofthe tool being used, review the material safety datasheet and/or consult your employer, the materialmanufacturer/supplier, governmental agencies such asOSHA and NIOSH and other sources on hazardousmaterials. California and some other authorities, forinstance, have published lists of substances known tocause cancer, reproductive toxicity, or other harmfuleffects.

Control dust, mist and fumes at the source wherepossible. In this regard use good work practices andfollow the recommendations of the manufacturers orsuppliers, OSHA/NIOSH, and occupational and tradeassociations. Water should be used for dustsuppression when wet cutting is feasible. When thehazards from inhalation of dust, mists and fumes cannotbe eliminated, the operator and any bystanders shouldalways wear a respirator approved by NIOSH/MSHA forthe materials being used.

B-46 TROWEL— GENERAL INFORMATION

B-46 Trowel Familiarization

This walk-behind trowel is designed for the floating andfinishing of concrete slabs.

Take a walk around the trowel. Take notice of all the majorcomponents (see Figure 3) like the engine, blades, Quick Pitch™handle, operator presence lever, etc. Check that there is alwaysoil in the engine.

Read all the safety instructions carefully. Safety instructions willbe found throughout this manual and on the trowel. Keep allsafety information in good, readable condition. Operators shouldbe well trained on the operation and maintenance of the trowel.

Before using your trowel, test it on a flat watered down section offinished concrete that is free of any debris and other objects.

This trial test run will increase your confidence in using the troweland at the same time it will familiarize you with the trowel’scontrols. In addition you will understand how the trowel handlesunder actual conditions.

Engine

This trowel is available with a 9 or 11 HP HONDA gasolineengine, or a 9 HP ROBIN gasoline engine. Refer to the engineowner’s manual for instructions regarding the operation andmaintenance of your engine. Please contact your nearestMultiquip Dealer for a replacement should the original manualdisappear or otherwise become unusable.

Training

For proper training, please use the “TRAINING CHECKLIST”located in the front of this manual (Page 8). This checklist willprovide an outline for an experienced operator to provide trainingto a new operator

Blades

The blades of the trowel finish the concrete as they are rotatedaround the surface. This trowel comes equipped with fourcombination (8 in./203mm wide) blades per rotor equallyspaced in a radial pattern and attached to vertical rotatingshaft by means of a spider assembly.

Drive System

Power is transferred from the engine to the gearbox input shaftvia a V-belt pulley drive system. The pulley engages using acentrifugal clutch. See Parts section of this manual.

Gearbox

The gearbox is located beneath the engine and transfers powerto the spider assembly. The gearbox controls the rotational speedof the trowel and is equipped with two shafts (input and output).

Guard Ring

This unit is equipped with a safety guard ring. It is designed tohelp protect items from coming into contact with the rotatingblades while in operation.

CAUTIONCAUTIONCAUTIONCAUTIONCAUTIONNEVER attempt to lift the trowel by yourself. ALWAYS getthe assistance of another person to help lift the trowel .

Operate the B-46 Trowel, tools and components in accordancewith the manufacturer's instructions. Use of any other tools forstated operation is considered contrary to designated use. Therisk of such use lies entirely with the user. The manufacturercannot be held liable for damages as a result of misuse.

Intended Use Spider

The vertical output shaft of the gearbox connects to a cast hubcalled the spider. The spider has 4 arms that extend outwardthat are used for attachment of blades or other accessories.Remember as the gearbox output shaft rotates so does the spiderassembly.

Safety Stop SwitchIn the event of a trowel runaway condition (operator releasesthe handlebars), the centrifugal safety stop switch willstop the engine and bring the trowel to a halt

If equipped with the optional operator presence lever, inthe event of a trowel runaway condition (operator releasesthe handle), the operator presence lever signals the safetystop switch which will stop the engine and bring the trowelto a halt.

INITIAL SERVICING

The engine (Figure 4) must be checked for proper lubrication andfilled with fuel prior to operation. Refer to the manufacturer's enginemanual for instructions & details of operation and servicing. Theengine shown above is a HONDA engine, operation for other typesof engines may vary somewhat.

1. Fuel Filler Cap – Remove this cap to add unleadedgasoline to the fuel tank. Make sure cap is tightenedsecurely. DO NOT over fill.

DANGER

B-46 TROWEL— BASIC ENGINE

2. Throttle Lever – Used to adjust engine RPM speed (leveradvanced forward SLOW, lever back toward operatorFAST).

3. Engine ON/OFF Switch – ON position permits enginestarting, OFF position stops engine operation.

4. Recoil Starter (pull rope) – Manual-starting method. Pullthe starter grip until resistance is felt, then pull briskly andsmoothly.

7. Air Cleaner – Prevents dirt and other debris from enteringthe fuel system. Remove wing-nut on top of air filtercannister to gain access to filter element.

Operating the engine without an airfilter, with a damaged air filter, or afilter in need of replacement willallow dirt to enter the engine,causing rapid engine wear.

11. Oil Drain Plug – Remove this plug to remove oil from theengine's crankcase.

12. Dipstick/Oil Filler Cap – Remove this cap to determine ifthe engine oil is low. Add oil through this filler port asrecommended in Table 4.

6. Choke Lever – Used in the starting of a cold engine, or incold weather conditions. The choke enriches the fuelmixture.

10. Fuel Tank – Holds unleaded gasoline. For additionalinformation refer to engine owner's manual.

9. Muffler – Used to reduce noise and emissions.

8. Spark Plug – Provides spark to the ignition system. Setspark plug gap according to engine manufacturer'sinstructions. Clean spark plug once a week.

NOTE

Adding fuel to the tank should be done onlywhen the engine is stopped and has had anopportunity to cool down. In the event of a fuelspill, DO NOT attempt to start the engine untilthe fuel residue has been completely wipedup, and the area surrounding the engine is dry.

5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stopthe flow of fuel.

B-46 TROWEL — INITIAL START-UP

This section is intended to assist the operator with the initialstart-up of the walk-behind trowel. It is extremely importantthat this section be read carefully before attempting to usethe trowel in the field.

DO NOT use your trowel until this section is thoroughlyunderstood.

DO NOT attempt to operate the trowel until the Safety,General Information and Inspection sections of this manualhave been read and thoroughly understood. Depending onengine manufacturer, operating steps may vary. See enginemanufactures operating manual. The following start-upprocedure makes reference to a HONDA Engine (ManualStart).

Auxiliary Lifting Tube

Remove the auxiliary lifting tube located on top of the main handle.Insert the tube into the socket located on the opposite side of thegearbox (Figure 23) from the handle.

Make sure that the hole in the tube engages with the pin in thesocket. With one person lifting from the main handle, and anotherlifting from the auxiliary lifting tube pick up the machine to moveonto a slab.

Figure 23. Lifting the Trowel

Lifting Bale

The lift bale (Item 10, page 17), provides an optimal lift point formoving the trowel. Lift bales or forklift can be used to lift a trowelup onto a building with a crane.

Using a crane to move a machine with a lift bale is highlyrecommended, and is perfectly safe for the machine. Extra careshould be taken when lifting the machine off the ground, however.Serious damage to the machine or personal injury could becaused by dropping a trowel.

The trowel is heavy and awkward to move around. Useproper heavy lifting procedures and DO NOT lift the trowelby the guard rings.

The trowel must be stabilized by the person carrying theoperator’s handle (Figure 23). If it is not stabilized properlythe handle may swing around and flip the trowel, thus causingdamage to the trowel and bodily injury.

B-46 TROWEL — OPERATION

Pitching The Blades

Quick Pitch Handle

1. To pitch the blades upwards using the "Quick-Pitch™"T-handle, (Figure 29) simply squeeze the trigger lockand pull the T-handle towards the operator. Pushingthe T-handle towards the engine will cause the bladesto lay flat.

Figure 29. Quick-Pitch™ T- Handle

Maneuvering the Trowel

1. Get into the operator’s position behind the handle. With asecure foothold and a firm grasp on the handles slowlyincrease the engine speed until the desired blade speed isobtained.

2. To maneuver the trowel, gently lift up on or press down on themain trowel handle. To move the machine to the operator’sleft, lift up on the handle, to move machine to the right, pushdown on the handle.

3. The best method for finishing concrete is to slowly walkbackwards (Figure 31) with the trowel, guiding the trowelfrom side to side. This will cover all footprints on wet concrete.

4. Remember that if you let go of the trowel, just step away andlet the trowel come to a complete stop before trying to recoverthe trowel.

The following steps are intended as a basic guide to machineoperation, and are not to be considered a complete guide toconcrete finishing. We suggest that all operators (experiencedand novice) read “Slabs on Grade” published by the AmericanConcrete Institute, Detroit, Michigan. Read the “Training”section of this manual for more information.

Stopping The Engine

1. Move the throttle lever to the IDLE or SLOW position andrun the engine for three minutes at low speed.

2. After the engine cools, turn the engine start/stop switch to the“OFF” position (Figure 30).

Blades are a vital part of finishing concrete. This trowel, orfinisher, has been designed to finish concrete and the blades arebuilt to stringent quality standards out of the finest trowel steel. Ifyou need replacement blades, consult your parts list in thismanual for part numbers and order them from your Multiquip partsdealer or importer.

Combo Blades

This trowel was equipped with combination float/finish (Figure33) blades as original equipment. These blades have beendesigned for optimum performance in both the floating andfinishing operations. These blades are versatile and should takecare of most troweling needs.

B-46 TROWEL — OPTIONS

Float Discs (Optional)

These round discs (Figure 36) attach to the spiders and allow themachine to “float” on “wet” concrete. The disc design allows earlyfloating and easy movement from wet to dry areas. They are alsovery effective in embedding large aggregates and surfacehardeners.

Clip-On Float Blades (Optional)

These blades will clip (Figure 35) on to an existing installed blade,allowing your finisher to float on “wet” concrete so that thetroweling operation can begin as early as possible. They areeasily removable, so that after the floating operation, when theconcrete is sufficiently cured, they can be removed to expose thefinish blades for continued troweling.

Figure 34. Finish Blade

Figure 35. Clip-On Float Blade

Figure 36. Float Disk

Finish Blades (Optional)

These blades (Figure 34) have been specifically designed forfinish operations with this trowel. They will provide a premiumsurface finishing capability from your trowel. They should only beused after the concrete has set to the point where the trowel doesnot sink into the concrete when placed on it.

B-46 TROWEL — MAINTENANCE

See the engine manual suppliedwith your machine for appropriateengine maintenance scheduleand troubleshooting guide forproblems.

ALWAYS allow the engine to cool beforeservicing. NEVER attempt any maintenancework on a hot! engine.

At the front of the book (Page 9) there is a “Daily Pre-OperationChecklist ”. Make copies of this checklist and use it on a dailybasis.


CAUTIONCAUTIONCAUTIONCAUTIONCAUTIONDisconnect the spark plug wire from the spark plug andsecure away from the engine before performingmaintenance or adjustments on the machine.

Figure 38. Blade Pitch Adjustment Bolt

The easiest and most consistent way to make adjustments onthe trowel arm fingers is to use the Trowel Arm Adjustment Fixture(P/N 9177) . It comes with all the hardware necessary to properlyaccomplish this maintenance and instructions on how to utilizethis tool.

If a trowel arm adjustment fixture is not available and immediateadjustment is necessary, temporary field adjustment can be madeif you can see or feel which blade is pulling harder by adjustingthe bolt that corresponds to that blade.

■ If one blade is completely worn out while the others looknew?

■ Does the machine have a perceptible rolling or bouncingmotion when in use?

■ Look at the machine while it is running, do the guard rings“rock up and down” relative to the ground?

■ Do the pitch control towers rock back and forth?

Look for the following indications if blades are wearing unevenly.If so, adjustment may be necessary.

Maintenance adjustment of blade pitch is made by adjusting abolt (Figure 38) on the arm of the trowel blade finger. This bolt isthe contact point of the trowel arm to the lower wear plate on thethrust collar. The goal of adjustment is to promote consistentblade pitch and finishing quality.

Changing Blades

It is recommended that ALL the blades on the entire machineare changed at the same time. If only one or some of the bladesare changed, the machine will not finish concrete consistentlyand the machine may wobble or bounce.

1. Place the machine on a flat, level surface. Adjust the bladepitch control to make the blades as flat as possible. Notethe blade orientation on the trowel arm. This is importantfor ride-on trowels as the two sets of blades counter-rotate.Lift the machine up, placing blocks under the main guardring to support it.

2. Remove the bolts and lock washers on the trowel arm, andthen remove the blade.

3. Scrape all concrete and debris from the trowel arm. This isimportant to properly seat the new blade.

4. Install the new blade, maintaining the proper orientationfor direction of rotation.

5. Reinstall the bolts and lock washers.

6. Repeat steps 2-5 for all remaining blades.

TttClean-Up

Never allow concrete to harden on the power trowel. Immediatelyafter use wash any concrete off the trowel with water, be carefulnot to spray a hot engine or muffler. An old paint brush or broommay help loosen any concrete that has started to harden.

Adjust the “high” bolts down to the level of the one that is nottouching, or adjust the “low” bolt up to the level of the higherones. If possible, adjust the low bolt up to the level of the rest ofthe bolts. This is the fastest way, but may not always work. Verifyafter adjustment the blades pitch correctly.

Blades that are incorrectly adjusted often will not be able to pitchflat. This can occur if the adjusting bolts are raised too high.Conversely, adjusting bolts that are too low will not allow theblades to be pitched high enough for finishing operations.

If, after making Blade Pitch adjustments the machine is stillfinishing poorly, blades, trowel arms, and trowel arm bushingsmay be suspect and should be looked at for adjustment, wear, ordamage. See the following sections.

Figure 39. Incorrect Spider Plate Alignment

Trowel Arm Adjustment

Figure 40 illustrates the "correct alignment " for a spider plate(as shipped from the factory).

Use the following procedure to check and adjust trowel arms,and check for worn or damaged components when it becomesapparent that the trowel is finishing poorly or in need of routinemaintenance.

A level, clean area to test the trowel prior to and after is essential.Any unlevel spots in the floor or debris under the trowel bladeswill give an incorrect perception of adjustment. Ideally, a 5 x 5 Ft.(1.5 x 1.5 Meter) three-quarter inch (19 mm) thick FLAT steelplate should be used for testing.

Figure 39 illustrates, "incorrect alignment", worn spiderbushings or bent trowel arms. Check that the adjustment boltis barely touching (0.10" max. clearance) lower wear plate. Allalignment bolts should be spaced the same distance from thelower wear plate.

■ Are blades wearing unevenly? Is one blade completelyworn out while the others look new?

■ Does the machine have a perceptible rolling or bouncingmotion when in use?

■ Look at the machine while it is running; do the guard rings“rock up and down” relative to the ground?

Look for the following indications. Trowel arm alignment, wornspider bushings or bent trowel arms may the cause.

1. Place the trowel in a FLAT, LEVEL area.

2. Pitch the blades as flat as possible. The adjustment boltsshould all barely make contact with the lower wear plate onthe spider. If one is not making contact, adjustment will benecessary. (Item 1, Figure 39).

B-46 TROWEL — MAINTENANCEA better way to determine which blades need adjustment is toplace the machine on a known FLAT surface (steel metal plate)and pitch the blades as flat as possible. Look at the adjustmentbolts. They should all barely make contact with the lower wearplate on the spider. If you can see that one of them is not makingcontact, some adjustment will be necessary.

1. Use a thick steel plate, granite slab or any surface which istrue and flat, to check all sides of each trowel arm for flatness.

2. Check each of the sides of the trowel arm (flat section). Afeeler gauge of .004" (0.10 mm) should not pass between theflat of the trowel arm and the test surface along its length onthe test surface. (Figure 46 item 3) .

Figure 46. Checking Trowel Arm Flatness

Checking Trowel Arm Straightness

Trowel arms can be damaged by rough handling, (such as droppingthe trowel on the pad), or by striking exposed plumbing, forms, orrebar while in operation. A bent trowel arm will not allow the trowelto operate in a smooth fluid rotation. If bent trowel arms are suspect,check for flatness as follows, refer to Figures 45 and 46:

1 Trowel Arm2 Flat Test Surface3 Feeler Gauge (.004 in. / 0.10 mm)4 Feeler Gauge (.005 in. / 0.127 mm)

1 Trowel Arm Round Shaft Section2 Trowel Arm Semi-Round Shaft Section3 Lever Mounting Slot (Left Arm Shown)4 Roll Pin Hole5 Blade Attachment Bolt Hole (One of Three)6 Flat of Semi-Round Shaft (Top of Arm)

Figure 45. Trowel Arm

Trowel Arm Adjustment

Shown in (Figure 47) is the adjustment fixture with a trowel arminserted. As each trowel arm is locked into the fixture, the arm boltis adjusted to where it contacts a stop on the fixture. This willconsistently adjust all of the trowel arms, keeping the finisher asflat and evenly pitched as possible.

1. Locate the trowel arm adjustment tool P/N 9177.

Figure 47. Trowel Arm Adjustment Tool Side View

NOTE

Arms with CLOCK-WISE bladerotation use the fixture arm in the UPposition (A in Figure 40). Arms withCOUNTER CLOCK-WISE bladerotation use the fixture with the fixturearm in the DOWN position. (B inFigure 48).

2. Ensure the fixture arm is in the proper setting (up or down) foryour trowel arm rotation as shown in Figure 48.

3. Next, check the clearance between the round shaft and thetest surface as one of the flat hex sections of the arm rests onthe test surface. Rotate the arm to each of the flat hex sectionsand check the clearance of the round shaft. Use a feelergauge of .005" (0.127 mm). Each section should have thesame clearance between the round of the trowel arm shaftand the test surface.

4. If the trowel arm is found to be uneven or bent, replace thetrowel arm.

4. Use an allen wrench to tighten the locking bolts securing thetrowel arm in place.

5. Adjust the bolt "distance" shown in Figure 49 to match oneof the arms. The other arms will be adjusted to match thisdistance.

7. Once the correct adjustment is made, tighten the lock nut onthe trowel arm to lock in place.

8. Loosen locking nuts on the adjustment fixture, and removetrowel arm.

9. Repeat steps for the remaining trowel arms.

Re-Assembly

1. Clean and examine the upper/lower wear plates and thrustcollar. Examine the entire spider assembly. Wire brush anyconcrete or rust build-up. If any of the spider components arefound to be damaged or out of round, replace them.

2. Make sure that the bronze trowel arm bushing is not damageor out of round. Clean the bushing if necessary. If the bronzebushing is damaged or worn, replace it.

3. Reinstall bronze bushing onto trowel arm.

4. Repeat steps 2 -3 for each trowel arm.

5. Make sure that the spring tensioner is in the correct positionto exert tension on the trowel arm.

6. Insert all trowel arms with levers into spider plate (with bronzebushing already installed) using care to align grease hole onbronze bushing with grease hole fitting on spider plate.

7. Lock trowel arms in place by tightening the hex head bolt withzerk grease fitting and jam nut.

8. Re-install the blades onto the trowel arms.

9. Install stabilizer ring onto spider assembly.

6. Loosen the locking nut on the trowel arm lever, then turn thetrowel arm adjusting bolt until it barely touches (.010") thefixture adjusting bolt.

10. Reinstall lower wear plate, thrust collar and upper wearring in the reverse order that they were dis-assembled ontothe spider shaft. Make sure that there is little or no lateralmovement between the thrust collar and the spider shaft.

13. Lubricate all grease points (zerk fittings) with premium"Lithum 12" based grease, conforming to NLG1 Grade #2consistency.

Testing

1. Place trowel in test area, start engine and test trowel forsmoothness.

2. If trowel bounces has excessive vibration or does not runsmoothly repeat alignment procedure.


1. Lift trowel just enough to slide pan under blades. Lowerfinisher onto pan with blades (item #1) adjacent to Z-Clips(item #4).

2. Rotate blades into position under Z-Clips. Ensure that theblades are rotated in the direction of travel when the machineis in operation or use the engine to rotate the blades intoposition.

3. Attach the blade tie-downs (item #3) to the far side of the Z-Clip brackets (item #4) with tie-down knobs (item #2) asshown in figure 51.

4. Check to make certain that the blade edges are securedunder the Z-Clips and the tie-downs are secured completelyover the edges of the blade bar before the machine is put backinto operation.

Decommissioning Trowel/ComponentsDecommissioning is a controlled process used to safely retire apiece of equipment that is no longer serviceable. If the equipmentposes an unacceptable and unrepairable safety risk due to wearor damage or is no longer cost effective to maintain, (beyond life-cycle reliability) and is to be decommissioned, (demolition anddismantlement), the following procedure must take place:

1. Drain all fluids completely. These may include oil, gasoline,hydraulic oil and antifreeze. Dispose of properly in accor-dance with local and governmental regulations. Never pouron ground or dump down drains or sewers.

2. The remainder can be brought to a salvage yard or metalreclamation facility for further dismantling.

Installing Pans Onto Finisher Blades

Refer to Figure 50 when installing pans onto finisher blades.

ALWAYS install pans either on the work area or on an areathat is next to and level with the work area. DO NOT lift thetrowel when the pans are attached.


These round discs sometimes referred to as "pans" attach to thespiders arms and allow early floating on wet concrete and easymovement from wet to dry areas. They are also very effective inembedding large aggregates and surface hardeners.
