J-SERIESTROWEL— GENERAL INFORMATION  
Blades  
J-SeriesWalk-BehindTrowel Familiarization  
The blades of the trowel finish the concrete as they are rotated  
around the surface. Blades are classified as combination (8  
inches wide), float (10 or 8 inches wide), and finish (6 inches  
wide).This trowel comes equipped with either three or four  
blades per rotor equally spaced in a radial pattern and  
attached to vertical rotating shaft by means of a spider  
assembly.  
This walk-behind trowel is designed for the floating and  
finishing of concrete slabs.  
Take a walk around the trowel. Take notice of all the major  
components (see Figure 3, pages 16 and 17) like the engine,  
blades, quick pitch control, air cleaner, centrifugal stop switch  
etc. Check that there is always oil in the engine.  
Read all the safety instructions carefully.Safety instructions will  
be found throughout this manual and on the trowel. Keep all  
safety information in good, readable condition. Operators should  
be well trained on the operation and maintenance of the trowel.  
Centrifugal Stop Switch  
In the event of a trowel runaway condition (operator releases  
the handle), a centrifugal stop switch, manual clutch or  
micro-switch depending which trowel you have, will stop  
the engine and bring the trowel to a halt.  
Before using your trowel, test it on a flat watered down section of  
finished concrete that is free of any debris and other objects.  
This trial test run will increase your confidence in using the trowel  
and at the same time it will familiarize you with the trowel’s  
controls. In addition you will understand how the trowel handles  
under actual conditions.  
CAUTION  
NEVER attempt to lift the trowel by yourself.  
ALWAYS get the assistance of another  
person to help lift the trowel or use a crane or  
lifting device to move the trowel.  
Engines  
This trowel is available with either an 5.0 HP HONDA, 4.6 HP  
ROBIN, or a 5.0 HP Briggs and Stratton gasoline engine. In  
addition, a 2.0 horsepower 115/230VAC, single phase electric  
motor is also available. Refer to the engine owner’s manual for  
instructions regarding the operation and maintenance of your  
engine.The engine manual is included with your trowel at the  
time of shipping from Whiteman. Please contact your nearest  
Multiquip Dealer for a replacement should the original manual  
disappear.  
Moving the J-Series Walk-BehindTrowel  
This walk-behind trowel is designed to be moved and handled  
in several ways. The easiest way to lift the trowel is to use the  
auxiliary lifting tube that is attached to the main handle. See  
page 24, Figure 19. When using the auxiliary tube, always use  
two persons to lift the trowel.  
Some models have a lifting bale (option) installed. A strap or  
chain can be attached to the lifting bale, allowing a forklift or  
crane to lift the trowel up onto a slab of concrete. Use a lifting  
device of adequate lifting capacity to lift the trowel.  
Drive System  
Power is transferred from the engine or electric motor to the  
gearbox input shaft via aV-belt or pulley drive system.The pulley  
engages using either a centrifugal or manual clutch. See page  
23.  
Training  
For proper training, please use the “TRAINING CHECKLIST”  
located in the front of this manual (Page 6). This checklist will  
provide an outline for an experienced operator to provide training  
to a new operator  
Gearbox  
The gearbox is located beneath the engine and transfers power  
to the rotor or spider assembly. The gearbox controls the  
rotational speed of the trowel and is equipped with two shafts  
(input and output).  
Spider  
The vertical output shaft of the gearbox connects to a cast hub  
called the spider.The spider has either 3 or 4 arms that extend  
outward that are used for attachment of blades or other  
accessories. Remember as the gearbox output shaft rotates so  
does the spider assembly.

This section is intended to assist the operator with the initial  
start-up of the walk-behind trowel. It is extremely important that  
this section be read carefully before attempting to use the trowel  
in the field.  
CAUTION  
The trowel is heavy and awkward to move  
around. Use proper heavy lifting procedures  
and DO NOT lift the trowel by the guard  
rings.  
DO NOT use your trowel until this section is thoroughly  
understood

DO NOT attempt to operate the trowel until  
CAUTION  
the Safety, General Information and  
Inspection sections of this manual have  
been read and thoroughly understood.  
Depending on engine manufacturer,  
operating steps may vary. See engine  
manufactures operating manual. The  
following start-up procedure makes  
reference to a HONDA 13 HP Engine  
(Manual Start)  
Removetheauxiliaryliftingtubelocatedontopofthemainhandle.  
Insert the tube into the socket located on the opposite side of the  
gearbox (Figure 19) from the handle.  
Make sure that the hole in the tube engages with the pin in the  
socket. With one person lifting from the main handle, and another  
lifting from the auxiliary lifting tube pick up the machine to move  
onto a slab.  
Starting the Engine (HONDA engine)  
1. Place the engine fuel valve lever (Figure 20) to the "ON"  
position.

carrying the operator’s handle (Figure 19).  
If it is not stabilized properly the handle may  
swing around and flip the trowel, thus causing  
damage to the trowel and bodily injury.  
2. Place the trowel's throttle lever (Figure 21) to the "ON"  
Lifting Bale (Option)  
position.  
The lift bale is optional on new trowels. It provides an optimal lift  
point for moving the trowel. Lift bales or forklift can be used to  
lift a trowel up onto a building with a crane. See “Optional  
Equipment” section in this manual for ordering information.  
Using a crane to move a machine with a lift bale is highly  
recommended, and is perfectly safe for the machine. Extra care  
should be taken when lifting the machine off the ground, though.  
Serious damage to the machine or personal injury could be  
caused by dropping a trowel.

J-SERIESTROWEL — OPERATION  
Maneuvering the Trowel  
The following steps are intended as a basic guide to machine  
operation, and are not to be considered a complete guide to  
concrete finishing. We suggest that all operators (experienced  
and novice) read “Slabs on Grade” published by the American  
Concrete Institute, Detroit, Michigan. Read the “Training”  
section of this manual for more information.  
1. Get into the operator’s position behind the handle. With a  
secure foothold and a firm grasp on the handles slowly  
increase the engine speed until the desired blade speed is  
obtained.  
If your trowel has a hand clutch (Figure 29), set your engine  
speed with the throttle, then pull on the hand clutch lever to  
startthebladesturning. Adjustthebladespeedafterthehand  
clutch is fully engaged.  
PitchingThe Blades.  
Quick Pitch Handle  
1. To pitch the blades upwards using the "Quick Pitch™"  
T-handle, (Figure 27) simply squeeze the trigger lock  
and pull the T-handle towards the operator. Pushing  
theT-handle towards the engine will cause the blades

2. To maneuver the trowel, gently lift up on or press down on the  
main trowel handle. To move the machine to the operator’s  
left, lift up on the handle, to move machine to the right, push  
down on the handle.  
3. The best method for finishing concrete is to slowly walk  
backwards (Figure 31) with the trowel, guiding the trowel  
from side to side.This will cover all footprints on wet concrete.  
Figure 28. Standard Handle  
4. Remember that if you let go of the trowel, just step away and  
let the trowel come to a complete stop before trying to recover  
the trowel.

J-SERIESTROWEL — OPERATION  
Continue to practice maneuvering the trowel.Try to practice as if  
you were finishing a slab of concrete. Practice edging and  
covering a large area. Remember a good finishing technique is  
to work backwards. Be careful when moving backwards so that  
hazards can be avoided.The best way to get accustomed to the  
trowel is repeated use.  
Figure 31 below illustrates a typical walk-behind trowel  
application. Practice maneuvering the trowel.The trick is to let  
the trowel do the work.

Clip-On Float Blades (Optional)  
Blades  
These blades will clip (Figure 34) on to an existing installed  
blade, allowing your finisher to float on “wet” concrete so that the  
troweling operation can begin as early as possible. They are  
easily removable, so that after the floating operation, when the  
concrete is sufficiently cured, they can be removed to expose the  
finish blades for continued troweling.

Lifting Bale  
There is a heavy duty, center balance type lifting bale (Figure 37)  
made specifically for your trowel. These bales are ideal for lifting  
and transporting your trowel.They are designed to lift the finisher  
and balance it on it’s center of gravity, providing great stability  
while lifting.This option is not available on electric trowel models.

J-SERIESTROWEL — MAINTENANCE  
Trowel Arm adjustment Procedure  
NOTE  
NOTE  
See the engine manual supplied with your  
machine for appropriate engine maintenance  
schedule and troubleshooting guide for  
problems.  
The following procedure should be followed  
to adjust trowel arms when it becomes  
apparent that the trowel is finishing poorly or  
in need of routine maintenance.  
At the front of the book (Page 7) there is a “Daily Pre-Operation  
Checklist ”. Make copies of this checklist and use it on a daily  
basis.  
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 blades  
will give an incorrect perception of adjustment. Ideally, a 5 x 5"  
three-quarter inch thick flat steel plate should be used for testing.  
CAUTION!  
1. To determine which blades need adjustment, place the  
trowelinthetestarea(three-quarterinchthickplate)andlook  
for the following conditions:  
■
Pitch the blades as flat as possible and look at the  
adjustment bolts.They should all barely make contact  
with the lower wear plate on the spider. If you can see  
that one of them is not making contact, some adjustment  
will be necessary.  
ALWAYS allow the engine to cool before  
servicing. NEVER attempt any maintenance  
work on a hot! engine.  
MAINTENANCE SCHEDULE  
Daily (8-10 Hours)  
■
Is the machine wearing out blades unevenly (i.e. one  
blade is completely worn out while the others look new)?  
Figure 39 below illustrates a "worn spider bushings or bent  
trowel arms". Check to see that adjustment bolt is barely  
touching (0.10" max. clearance) lower wear plate. All alignment  
bolts should be spaced the same distance from the lower wear  
plate.  
1.  
Check the oil level in the engine crankcase and gear box,  
fill as necessary.  
2.  
CheckV-belt.

Hand Clutch Adjustment  
10. Carefully lift the upper trowel assembly, line up the key-  
wayongearboxmainshaftandinsertintospiderassembly  
Sometrowels are equippedwithahand-operatedclutchinstead  
of an automatic centrifugal clutch.Two types of hand clutches  
have been installed.Both are belt-tightener type clutches.They  
operate by removing slack in the V-belt which then transmits  
power from the engine to the gearbox.  
11. Reinstall square head cone point into spider plate and  
tighten in place.Tighten jam nut. Use care in making sure  
point of set screw engages groove in gear box main shaft.  
12. Lubricate all grease points (zerk fittings) with premium  
"Lithum 12" based grease, conforming to NLG1 Grade #2  
consistency.  
There are two reasons to adjust the hand clutch: 1) operator  
comfort;2)initialbeltstretchandbreak-in.  
The easiest and most simple adjustment is to adjust the clutch  
cablehousingusingtheadjustmentnut(Figure48)locatedonthe  
clutch lever. Rotating the nut provides either more or less  
(depending upon the direction of rotation) clutch engagement.  
Testing  
1. Place trowel in test area, start engine and test trowel for  
smoothness.  
2. If trowel bounces has excessive vibration or does not run  
smoothlyrepeatalignmentprocedure.  
Changing a Blade  
Whiteman recommends that all the blades be changed at the  
same time.The machine may wobble or bounce if only some of  
the blades are changed at one time.  
Figure 48. Trowel Arm AdjustmentTool  
Hand Clutch Disengagement  
1. Place the machine on a flat, level surface. Adjust the blade  
pitchcontroltomakethebladesasflataspossible.Notethe  
blade orientation on the trowel arm.  
1. Startthetrowelasoutlinedinthe"InitialStart-up"section"  
in this manual. Move the throttle lever so that the engine is  
running about 1/4 to 1/3 of full speed.  
NOTE  
2. Gripthetrowelhandlefirmlyandcarefullyengagetheclutch  
bysqueezingtheclutchlevertowardthehandlewithyourleft  
hand.Afterthetrowelisstabilizedandyoufeelcomfortable  
with its operation, use your right hand to adjust the housing  
adjustmentnut.  
Before removing the blades, please note  
the orientation of the blade on the trowel  
arm.  
3. Rotating the nut so that it backs out of the lever housing  
increases the engagement and also the squeezing force  
required to keep it engaged.  
1. Remove the three bolts and lock washers that secure the  
blade to the trowel arm. Remove the blade.  
2. Usingawirebrush,scrapeallconcreteparticles andforeign  
debris from the trowel arm.  
Too much squeezing force may cause premature hand  
fatigue. Too little squeezing force may cause belt slippage  
and premature belt wear. Each operator should experiment  
with the adjustment to get the optimum combination of  
squeeze force and belt grip.  
3. Install the new trowel blade onto the trowel arm. Make sure  
blade is installed correctly, maintaining the proper orienta-  
tion for direction of rotation.  
4. After initial break-in (approximately 8 hours) the above  
procedure should be repeated to attain optimum operator  
comfort and belt wear.  
4. Reinstall the three bolts and lock washers that secure the  
blade to the trowel arm.Tighten all three bolts securely.  
5. Repeat steps 1-4 for all remaining blades.  
5. After considerable belt wear, the adjustments mentioned  
abovemayhavealittleornoeffectonclutchengagement.If  
this is the case, the belt should be replaced.

Make certain blades are in good condition, not excessively worn.  
Finish blades should measure no less than 2" (50mm) from the  
blade bar to the trailing edge, combo blades should measure no  
less that 3.5" (89mm). Trailing edge of blade should be straight  
and parallel to the blade bar.  
Blades?  
Check that all blades are set at the same pitch angle as  
measured at the spider. A field adjustment tool is available for  
height adjustment of the trowel arms (see Optional Equipment).  
Spider?  
Check the spider assembly for bent trowel arms. If one of the  
arms is even slightly bent, replace it immediately.  
Bent trowel arms?  
If trowel “bounces, rolls  
concrete, or makes uneven  
swirls in concrete”.  
Check the trowel arm bushings for tightness. This can be done by  
moving the trowel arms up and down. If there is more than 1/8"  
(3.2 mm) of travel at the tip of the arm, the bushings should be  
replaced. All bushings should be replaced at the same time.  
Trowel arm bushings?  
Check the flatness of the thrust collar by rotating it on the spider.  
If it varies by more than 0.02" (0.5 mm) replace the thrust collar.  
Thrust collar?  
Check the thrust collar by rocking it on the spider. If it can tilt  
more than 3/32" (2.4 mm) [as measured at the thrust collar O.D.],  
replace the bushing in the thrust collar.  
Thrust collar bushing?  
Thrust bearing worn?  
Check the thrust bearing to see that it is spinning free. Note:  
Thrust cap, replace if necessary.  
The main output shaft of the gearbox assembly should be  
checked for straightness. The main shaft must run straight and  
cannot be more than 0.003" (0.08 mm) out of round at the spider  
attachment point.  
Main shaft?  
Machine has a perceptible  
rolling motion while running.  
Check to make sure that both fingers of the yoke press evenly on  
the wear cap. Replace yoke as necessary.  
Yoke?  
Check to ensure that each blade is adjusted to have the same  
pitch as all other blades. Adjust per maintenance section in  
manual.
