safety information in good, readable condition. Operators should
be well trained on the operation and maintenance of the trowel.

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.

Engines
This trowel is available with either an 5.5 HP HONDA, 6 HP

ROBIN, or a 5.5 HP Briggs and Stratton gasoline engine.

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 or become
unusable.

JA-SERIES TROWEL— CONTROLS AND COMPONENTS

Figures 3 shows the location of the Basic controls or components,
for the JA-Series trowel. Listed below is a brief explanation of
each control or component

1. Quick Pitch™ Control Handle – To adjust the pitch of
the blades, grasp the handle then squeeze and either move
the handle forward or backward to achieve the desired
blade pitch.

2. Handlebar Adjuster – Change the angle/height of the
handle bars by loosening star wheel, adjust handlebars to
desired location, tighten starwheel firmly to hold handlebars
in that position.

3. Hand Grip/Handlebar – When operating the trowel, place
both hands on each grip to maneuver the trowel. Replace
hand grips when they become worn or damaged.

4. Throttle Control Grip – Controls the speed of the engine.
Rotate the hand grip away from the operator to increase
engine speed (high), toward the operator to decrease
engine speed (low).

5. Throttle – Controls engine speed when throttle control
grip is rotated.

15. Engine – This trowel uses Honda, Robin and Briggs and
Stratton type gasoline engines.

16. Trowel Arm – NEVER operate the trowel with a bent,
broken or out of adjustment trowel arm. If the blades show
uneven wear patterns or some blades wear out faster than
others, the trowel arm may need to be adjusted. Use the
trowel arm adjustment tool P/N 1817 to adjust the trowel
arms.

17. Blades – This trowel is equipped with combination blades.
These blades are versatile and should take care of most
troweling needs. In addition float discs can be attached to
the trowel arms that will allow the trowel to float on "wet"
concrete.

6. Hand Grip/Handlebar – When operating the trowel, place
both hands on each grip to maneuver the trowel. Replace
hand grips when they become worn or damaged.

7. Centrifugal Kill Switch – In the event the operator loses
control of the trowel, this switch will shut-down the engine.

8. Auxiliary Lifting Tube - Use this tube to lift the trowel onto
a slab. Tube is to be inserted into socket located in front of
the gearbox.

9. V-Belt Cover – Remove this cover to gain access to the V­belt. NEVER operate the trowel with this cover removed.

10. Trowel Lifting Point – Insert the auxiliary lifting tube here.
See Figure 21.

11. Pitch Control (standard models) - Turn this "Star Wheel"
clockwise for increase blade pitch, and counter-clockwise
for decrease blade pitch.

12. Clutch Lever - Clutch engagement lever. When this lever
is engaged, the blades will begin to rotate. May be used
with either Quick Pitch™ or Standard handle.

13. Main Tube - When disassembling components inside the
tube exercise extreme CAUTION! Tube is spring-loaded,
severe injury could result if not disassembled correctly.

14. Guard Ring- NEVER put hands or feet inside guard ring.

Figure 4. Engine Controls and Components

INITIAL SERVICING

The engine (Figure 4) must be checked for proper lubrication and
filled with fuel prior to operation. Refer to the manufacturers engine
manual for instructions & details of operation and servicing. The
engine shown above is a HONDA engine, operation for other
types of engines may vary somewhat.

1. Fuel Filler Cap – Remove this cap to add unleaded
gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT over fill.

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

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

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

DANGER

Adding fuel to the tank should be done only when

the engine is stopped and has had an opportunity to
cool down. In the event of a fuel spill, DO NOT attempt to start the
engine until the fuel residue has been completely wiped up, and the
area surrounding the engine is dry.

2. Throttle Lever – Used to adjust engine RPM speed (lever

).

, lever back toward operator

8. Spark Plug – Provides spark to the ignition system. Set
spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch) Clean
spark plug once a week.

9. Muffler – Used to reduce noise and emissions.

NOTE

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

WARNING

3. Engine ON/OFF Switch – ON position permits engine
starting, OFF position stops engine operations.

4. Recoil Starter (pull rope) – Manual-starting method. Pull
the starter grip until resistance is felt, then pull briskly and
smoothly.

PAGE 18 — JA-SERIES WALK-BEHIND TROWEL— OPERATION AND PARTS MANUAL — REV. #9 (07/02/10)

while the engine is running or immediately after operating. NEVER
operate the engine with the muffler removed.

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

Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas

JA-SERIES TROWEL — ASSEMBLY AND INSTALLATION

Assembly and Installation

Before the trowel can be put into operation there are some
components that must be installed before the trowel can be used.
This section provided general instructions on how to install those
components. Instruction sheet P/N 20485 provides further details
for the handle assembly.

Handle Tube Installation (All Models)

1. Install the

handle tube

to the gearbox as shown in (Figure 5).
The mounting hardware should be contained in the shipping
container.

Figure 5. Handle Tube Installation

2. On Quick-Pitch™ models, pivot the

T-handle

back
(full pitch) (Figure 6). This will relax the spring inside the
handle tube. On either model, spread the handle bar ends
just enough to engage the teeth on the handle tube. Attach
the hand wheel assembly, position handlebar to desired
location, and tighten hand wheel firmly.

CAUTIONCAUTION

CAUTION

CAUTIONCAUTION

The Quick-Pitch™ handle is spring loaded,
personal injury or damage could result from
improper handling or installation. Be careful

application. Practice maneuvering the trowel. The trick is to let
the trowel do the work.

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.

Clip-On Float Blades (Optional)

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.

Float Discs (Optional)

These round discs (Figure 35) 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
very effective in embedding large aggregates and surface
hardeners.

Spider Removal

1. Once it is determined that an adjustment is required, remove
the spider assembly from the gearbox shaft as follows:

1. Each trowel arm is held in place at the spider plate by a hex
head bolt (zerk grease fitting) and a roll pin. Remove both the
hex head bolt and the roll pin (Figure 42) from the spider
plate.

Hand Clutch Adjustment

Some trowels 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
power from the engine to the gearbox.

12. Lubricate all grease points (zerk fittings) with premium

based grease, conforming to NLG1 Grade #2

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

consistency.

Testing

1. Place trowel in test area, start engine and test trowel for
smoothness.

The easiest and most simple adjustment is to adjust the clutch
cable housing using the adjustment nut (Figure 47) located on the
clutch lever. Rotating the nut provides either more or less
(depending upon the direction of rotation) clutch engagement.

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

Figure 47. Clutch Cable Adjustment

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.

Hand Clutch Disengagement

1. Start the trowel as outlined in the "
in this manual. Move the throttle lever so that the engine is
running about 1/4 to 1/3 of full speed.

NOTE

Before removing the blades, please note
the orientation of the blade on the trowel
arm.

2. 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.

3.

2. Remove the three bolts and lock washers that secure the
blade to the trowel arm. Remove the blade.

3. Using a wire brush, scrape all concrete particles and foreign
debris from the trowel arm.

4. Install the new trowel blade onto the trowel arm. Make sure
blade is installed correctly, maintaining the proper orienta­tion for direction of rotation

5. Reinstall the three bolts and lock washers that secure the

.

blade to the trowel arm. Tighten all three bolts securely.

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.

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

this is the case, the belt should be replaced.
