Preload adjustment for QUICK PITCH

After the handle is installed on the machine, spring preload
adjustment will be required. Locate the adjustment screw on the
underside of the handle. A decal has been placed there to assist
in the adjustment. Turn the screw to adjust until it lines up with the
arrow on the decal matching your setup. Test pitch control operation.
Adjust if necessary.

If you want to be able to increase the blade pitch using less arm
force, adjust the block away from the gearbox. Be aware, this will
also require more force to decrease the blade pitch. If you want
to be able to decrease the blade pitch using less arm force, adjust
the block toward the gearbox.

HANDLE ASSEMBLY — STANDARD HANDLE

Turn the pitch adjustment knob (located on the operator end of the
handle) counter-clockwise until resistance is felt.

Attach the handle tube to gearbox as shown in the QUICK PITCH
handle installation. Bolts are to be inserted from the bottom side
of the handle. Note that the bolt on the engine side must have a
washer between the gearbox and the nut. The second bolt carries
the auxiliary lift handle bracket in the place of a washer.

Remove one brass nut from the cable end. Thread the second
brass nut towards the cable as far as possible. Insert the cable end
into yoke as shown in the QUICK PITCH installation. Replace the
brass set nut on the cable end. Tighten the set nut by finger as far
as possible to remove slack from the cable. Using a wrench,
tighten the locking nut on the other side of the boss to lock the cable
in place.

SAFETY KILL WIRE

Locate the red wire protruding from the handle tube and connect
it to the red wire tail on the engine. Test to insure proper operation!

HANDLE HEIGHT ADJUSTMENT

If handle height adjustment is desired, a handle wedge kit can be
purchased for your machine by ordering Part Number 2576 from
your Multiquip dealer. These wedges are placed between the
handle and the gearbox to adjust the operating height of the
handle. This kit comes complete with wedges, new bolts and
installation instructions. This will move your operating handle
position up or down approximately 3” (76mm).

THROTTLE CABLE INSTALLATION

Note: A red wire piece has been placed on the engine
throttle assembly to show where the throttle cable from
your handle should be placed.

J-SERIES TROWEL — OPERATION AND PARTS MANUAL — REV. #3 (07/07/10) — PAGE 9

Handling

Machine is heavy and awkward to move around.

Use proper heavy lifting procedures and DO

NOT LIFT THE MACHINE BY GUARD RINGS.

Moving the Machine

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 the
gearbox 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 it, as shown in the following diagram.

Machine Operations

CONTROLS

Safety Kill Switches

Your Whiteman finisher has been equipped with a safety kill
switch or a hand operated clutch. Safety kill switches should be
tested every time the engine is started.

Note: NEVER disable or disconnect the kill switch. It is provided
for operator safety. Injury may result if it is disable, disconnected
or improperly maintained.

Centrifugal Type

This is a red switch located on the main handle tube. The switching
mechanism should operate freely and should be kept in this
condition. With the switch in the OFF position, the engine should
not start or run. The purpose of this switch is to stop the engine in
a runaway situation, (i.e.-the operator releasing the handle during
operation).

Caution! The machine must be stabilized by the

person carrying the operator’s handle. If it is not

stabilized properly by this person it will rotate

upside down.

Lift Bale

The lift bale is optional on new machines. It provides an optimal
lift point for moving the finisher. Lift bales can be used to lift a
machine up onto a building with a crane. They can also be used
to lift a machine up onto a slab with a forklift machine. 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
finisher. See “Optional Equipment” in this manual for ordering
information.

Hand Clutch

Some finisher models are equipped with a hand operated clutch.
These units are not equipped with a safety kill switch since the unit
automatically stops rotating when the clutch lever is released.
Clutch operation should be tested each time the machine is
started.

Do not let the machine sit unused with the engine at high speed
for an extended period of time. It will cause premature belt wear
or may destroy the belt. Always set the engine speed to idle when
the hand clutch is disengaged.

J-SERIES TROWEL — OPERATION AND PARTS MANUAL — REV. #3 (07/07/10) — PAGE 11

J-SERIES TROWEL — INSTRUCTIONS

Blade Pitch — Standard Handle

The pitch control on machines equipped with the standard handle
is a big star-wheel knob located at the operator end of the main
handle tube. Pitch is controlled by turning the knob. Clockwise for
increased blade pitch, counter-clockwise for decreased blade
pitch.

Blade Pitch — QUICK PITCH™ handle

Pitch is controlled on machines with this option by a T-shaped
lever located on the top of the main handle tube. To change the
blade pitch, pull the locking control up to the T-handle. Pulling the
handle towards the operator will increase blade pitch. Pushing
the handle away from the operator will decrease the blade pitch.
See page 8 for adjustment.

Electric Control Switch (electric motors only)

Located on the control handle, this switch transfers power to the
electric motor when grasped.

Electric On-Off Switch (electric motors only)

Located on the handle, it is the main power control switch.

Engine Operation

Gearbox Oil Level

on the gearbox, there are two of them. Removal of the bottom-most
plug (DRAIN PLUG) will drain the oil. The level should be up to
the bottom of the fill plug hole, located approximately half way up
the side of the gear box. If needed, refill with specifically formulated
Whiteman gearbox lubricant (P>N> 10139) or ISO 680 oil.

Operation

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. Check oil levels in the engine and gearbox.

Check the oil level before starting the engine.

Because of the number of engine options, please
refer to engine owner’s manual for specific
instructions regarding engine operation.

Check the gearbox oil level daily.

Check the gearbox oil level by removing the plug
located on the side of the gearbox. It will be
clearly marked by the “check” decal (see Machine
Decals section). Take care when removing plugs

PAGE 12 — J-SERIES TROWEL — OPERATION AND PARTS MANUAL — REV. #3 (07/07/10)

2. Check to make sure that the fuel control valve is on and fuel
is in the tank.

3. Set safety kill switch (if equipped with centrifugal type clutch)
to ON position.

4. Set throttle to idle position.

J-SERIES TROWEL — INSTRUCTIONS

NEVER start the engine with the throttle
above the idle position.

5. Grasp the control handle with left hand. Pull
slowly on starter rope until resistance is felt, then
pull briskly to start the engine. If the engine fails

to start after several tries, consult the engine owner’s manual.

6. After the engine starts, let it warm up by idling for a few minutes.

7. Test the safety kill switch. If you have the centrifugal type clutch,
try momentarily switching the kill switch to the OFF position. If your
safety kill switch is working properly, the engine on your finisher
should stop.

8. 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 blades speed is obtained. If your
finisher has a hand clutch, set your engine speed with the throttle,
then pull on the hand clutch lever to start the blades. Adjust the
blade speed after the hand clutch is fully engaged.

9. To maneuver the machine, 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.

10. The best method for finishing concrete is to slowly walk
backwards with the machine, guiding the machine from side to
side as you do so. See the diagram in the “Whiteman Suggested
Training Checklist” at the end of this manual.

Always look behind you to avoid hazards
before moving backwards.

Cleanup

NEVER allow concrete to harden on the power trowel.

Immediately after use, wash any concrete off your trowel with
water. Be careful not to spray water on the engine. An old
paintbrush or broom may help loosen any concrete that has
started to harden.

Coat the blades and blade arms with diesel fuel after cleaning.
This should help prevent rusting and allow for easier cleanup in
the future.

Maintenance (Service, Adjustment and Repair)

Note: See the engine manual supplied with your machine
for appropriate engine maintenance schedule.

There is a “Daily Preoperation Check List” at the end of this
manual . Please feel free to make copies of it and use it on a daily
basis.

Maintenance Schedule

Daily (8-10 Hours)

Check the fluid levels in the engine and gearbox.

Weekly (50-60 Hours)

Relube arms, thrust collar and clutch.

Replace the blades if necessary.

Check and clean or replace the engine air filter as necessary.

Monthly (200-300 Hours)

Remove, clean, reinstall and relube the arms, thrust collar and
clutch.

Adjust the blade arms.

Yearly (2000-2500 Hours)

Check and replace if necessary the arm bushings, thrust collar
bushings, shaft seals and belts.

Check pitch control cable for wear.

SERVICE PROCEDURES

Checking Belt Tension

The first indication of belt wear is a reduced blade speed despite
the engine running at full speed. Inspect belts often for signs of
damage or excessive wear.

There is no method for manual adjustment of belt tension.
Excessively worn belts must be replaced.

Blade Pitch Adjustment Procedure

The maintenance adjustment of blade pitch is an adjustment that
is made by a bolt on the arm of the trowel blade finger. This bolt
is the contact point of the trowel arm to the lower wear plate on the
spider. The goal of adjustment is to promote consistent blade
pitch.

There are some things to look for when checking to see if
adjustment is necessary. Is the machine wearing out blades
unevenly (i.e. one blade is completely worn out while the others
look new)? Does the machine have a perceptible rolling motion?
Look at the machine while it is running, do the guard rings “rock
up and down” relative to the ground? These are some indications
that the blade pitch needs to be adjusted.

J-SERIES TROWEL — OPERATION AND PARTS MANUAL — REV. #3 (07/07/10) — PAGE 13

J-SERIES TROWEL — INSTRUCTIONS

The easiest way to make this adjustment is to use the Trowel Arm
Adjustment Fixture, Part Number 1817 (pictured below) that is
manufactured by Whiteman. This fixture will allow consistent
adjustment of the trowel arm fingers. It comes with all the hardware
necessary to properly accomplish this maintenance and
instructions on how to properly utilize this tool. Adjusting the trowel
arm fingers without a fixture requires a special talent.

If a trowel arm adjustment fixture is not available and immediate
adjustment is necessary , we suggest the following procedure. If
you can see or feel which blade is pulling harder, adjust the bolt
that corresponds to that blade. Another way to determine which
blades need adjusting is to place the machine on a flat surface and
pitch the blades as flat as possible. Now, 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 os them is not making
contact, some adjustment will be necessary.

It is possible to either adjust the “high” bolts down to the level of
the one that is not touching, or adjust the “low” bolt up to the level
of the higher ones. Verify that after adjustment, the blades will pitch
correctly. Often times, if the blades are incorrectly adjusted, they
will not be able to pitch flat. This is due to the adjusting bolts being
raised too high. Conversely, some times the adjusting bolts are too
low and the blades cannot be pitched enough.

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.

1. Place the machine on a flat, level surface. Adjust the blade pitch
control to make the blades as flat as possible. Note the blade
orientation on the trowel arm.

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

3. Scrape all concrete particles from the trowel arm.

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

5. Affix the bolts and lock washers.

6. Repeat steps 2-6 for all of the remaining blades.

Hand Clutch Adjustment

Some Whiteman finishers are equipped with a hand-operated
clutch instead 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.

There are two reasons to adjust the hand clutch: 1) operator
comfort; 2) initial belt stretch and break-in.

The easiest and most simple adjustment is to adjust the clutch
cable housing using the adjusting nut located on the clutch lever.
Rotating the nut provides either more or less (depending upon the
direction of rotation) clutch engagement.

about 1/4 to 1/3 of full speed. Grip the trowel handle firmly and
carefully engage the clutch by squeezing the clutch lever toward
the handle with your left hand. After the trowel is stabilized and you
feel comfortable with its operation, use your right hand to adjust
the housing adjustment nut. 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. 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.

After initial break-in (approximately 8 hours) the above procedure
should be repeated to attain optimum operator comfort and belt
wear.

After considerable belt wear, the adjustments mentioned above
may have a little or no effect on clutch engagement. If this is the
case, the belt should be replaced.

Always check to verify that the clutch will
properly disengage!

For operator comfort: start the trowel following
the instruction given earlier in this manual. Move
the throttle lever so that the engine is running

SYMPTOM POSSIBLE PROBLEM SOLUTION

Engine running rough or not at all.

Kill switch off or malfunctioning? Make sure that the kill switch is on or replace switch if necessary.

Other problems? Consult engine manufacture’s manual.

Safety kill switch not functioning.

Loose wire connections? Check wiring. Replace switch if necessary.

Bad contacts? Replace switch.

Clutch slipping or sluggish response to engine speed change.

Worn belts? Replace.

Dirty centrifugal clutch? Disassemble and clean the clutch.

Worn out centrifugal clutch? Replace entire clutch.

Hand clutch out of adjustment? Adjust as per instructions in Maintenance section.

Worn hand clutch parts? Replace parts as necessary.

Worn bearings in gearbox? Rotate input shaft by hand. If it rotates with difficulty check the input and output shaft bearings. Replace
if necessary.

Worn or broken gears in gearbox? Check in particular to verify that the gearbox output shaft rotates when the input shaft is rotated.
Replace both worm and worm gear as a set.

If trowel “bounces, rolls concrete, or makes uneven swirls in concrete”.

Blades? Make certain blades are in good condition, not excessively worn. Finish blades should measure no less than 2" (50 mm) from
the blade bar to the trailing edge, combo blades should measure no less than 3-1/2" (89mm). Trailing edge of blade should be straight
and parallel to the blade bar.

Spider? 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 section).

Bent trowel arms? Check the spider assembly for bent trowel arms. If one of the arms is even slightly bent, replace immediately.

Trowel arm bushings? Check the trowel arm bushing for tightness. This can be done by moving the trowel arms up and down. If there
is more than 1/8" (3.2mm) of travel at the tip of the arm, the bushings should be replaced. All bushings should be replaced at the same
time.

Thrust collar? Check the flatness of the thrust collar by rotating it on the spider. If it varies by more than 0.02" (0.5mm) replace the thrust
collar.

Thrust collar bushings? Check the thrust collar by rocking it on the spider. If it tilts more than 1/16" (1.6mm) (as measured at the thrust
collar O.D.), the bushing in the thrust collar should be replaced.

Thrust bearing worn? Check the thrust bearing to see that it is spinning free and has not worn into the thrust cap. Replace if necessary.

Machine has a perceptible rolling motion while running.

Main shaft? 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" (0.08mm) out of round at the spider attachment point.

Blade pitch? Check blades for consistent pitch. Adjust per Maintenance section instructions if necessary.

J-SERIES TROWEL — OPERATOR TRAINING

Operator Training

SUGGESTED TRAINING

Note: ONLY QUALIFIED AND EXPERIENCED PERSONNEL
SHOULD OPERATE THIS EQUIPMENT

Before taking your new equipment to the job site for it’s first
use, there are a few things that should be considered before
operation.

Handling

Know how to transport your trowel properly. Keep in mind that
you will need to place your trowel on a slab of concrete in the
middle of construction area. How will you accomplish this? Do
you need any special equipment for lifting or transport? These
are questions that you should be able to answer.

Operation

Perhaps it would be wise to familiarize yourself with machine
operation before placing your machine on a slab. It would of use
to understand how your trowel will behave and how it is
controlled. The best way to do this is to test run your machine.

To test run your machine, place it on a flat piece of existing
finished concrete. Before starting the machine, make sure that
the area around the machine is clear of any obstructions and
people. Test running your machine will give a good idea as to
how the machine will operate under normal conditions. Keep in
mind that running a machine on dry concrete could wear your
blades at an accelerated rate.

Training Checklist

For proper operator training please use the attached sheet
OPERATOR TRAINING CHECKLIST. It is located at the end of
this manual. This sheet will list some of the minimums for basic
operation of the machine. Please feel free to detach it and
make copies. This sheet is a checklist by which an experienced
operator can provide training to a new operator. This sheet
should help to familiarize the new operator with the machine.
It covers basic machine controls and use, but it is not to be
considered a complete training exercise. Nor is it to be
considered a complete guide to concrete finishing.

J-SERIES TROWEL — OPTIONAL EQUIPMENT

BLADES

Note: BLADES SHOULD BE CHANGED WHEN THEY FAIL TO
FINISH CONCRETE IN A SATISFACTORY MANNER.

Blades are a vital part of finishing concrete. This Whiteman
finisher has been designed to finish concrete with Whiteman and
are built to stringent quality standards out of the finest trowel steel.
If you need replacement blades, consult your parts list in this
manual for part numbers and order them from your Multiquip parts
dealer or importer.

Combo Blades

This trowel was equipped with combination FLOAT/FINISH
blades as original equipment. These blades have been designed
for optimum performance in both the floating and finishing
operations. These blades are versatile and should take care of
most troweling needs.

Finish Blades

These blades have been specifically designed for finish operations
with this trowel. They will provide a premium surface finishing
capability from your trowel. They should only be used after the
concrete has set to the point where the machine does not sink into
the concrete when placed on it .

Clip-On Float Blades

These blades will clip 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.

Float Discs

These round discs attach to the spiders and allow the machine
to “float” on “wet” concrete. The disc design allows early floating
and easy movement from wet to dry areas. They are also quite
effective in embedding large aggregates and surface hardeners.

FIELD TROWEL ARM ADJUSTMENT TOOL

If blades show uneven wear patterns or some tend to wear out
faster than others, the trowel arms may need to be adjusted.
Whiteman makes a special tool that will adjust all of the trowel
arms consistently, Part Number 1817-Trowel Arm Fixture.

Shown here is the adjustment fixture with an arm. As each arm is
locked into the fixture, the arm bolt is adjusted to where it contacts
a stop on the fixture. This will consistently adjust all of the trowel
arms, keeping the finisher as flat and evenly pitched as possible.
See Blade Pitch Adjustment Procedure in the Maintenance
section of this manual for more information.

LIFT BALE

There is a heavy duty, center balance type lifting bale 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.

GRINDING ATTACHMENTS

Available grinding attachments are used for grinding surface
imperfections or joints. These attachments allow greater utilization
of your trowel.
