THIS MANUAL MUST ACCOMPANY THE EQUIPMENT AT ALL TIMES.

P/N 20382

Engine exhaust and some of
its constituents, and some dust created
by power sanding, sawing, grinding,
drillingand other constructionactivities
contains chemicals known to the State
of California to cause cancer, birth
defects and other reproductive harm.
Some examples of these chemicals are:

Leadfromlead-based paints.
Crystallinesilica frombricks.
Cementand other masonryproducts.
Arsenicandchromiumfromchemically
treatedlumber.

Your risk from these exposures varies,
dependingon howoftenyoudo thistype
of work. To reduce your exposure to
these chemicals: work in aALWAYS
well ventilated area, and work with

approved safety equipment, such as

dust masks that are specially designed
to filter out microscopic particles.

WARNING

SILICOSIS WARNING RESPIRATORY HAZARDS

Grinding/cutting/drilling of masonry, concrete, metal and
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.

WARNING

Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.

Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

HHN -31V — GENERAL INFORMATION

HHN RIDE-ON TROWEL FAMILIARIZATION

The HHN series Ride-On Power Trowel is designed for the
floating and finishing of concrete slabs.

Take a walk around the HHN Ride-On Power Trowel. Take notice
of all the major components (see Figures 2 and 3, pages 13 and

14) like the engine, blades, air cleaner, fuel system, fuel shut-off
valve, ignition switch etc. Check that there is always oil in the
engine, and gear oil in the gear box assembly.

Read all the safety instructions carefully. Safety instructions will
be found throughout this manual and on the machine. Keep all
safety information in good, readable condition. Operators should
be well trained on the operation and maintenance of the HHN
Ride-On Power Trowels.

Look at the operator control levers. Grab the control levers and
move them around a bit. Look to see how moving the control
levers causes the gearboxes and frame to move.

Notice the foot pedal which controls the engine speed. Also take
a look at the main driveline of the trowel. Take note and reference
how the belts look, this is the way the belts should look when
adjusted properly.

Before using your HHN Ride-On Power Trowel, test it on a flat
watered down section of finished concrete. 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 and indicators.
In addition you will understand how the trowel will handle under
actual conditions.

Engine

Gearboxes

The HHN Ride on Power Trowel consist of two separate gearbox
assemblies that are enclosed in rugged cast aluminum gear
cases.

The gearbox casing holds 50% more oil capacity than
competitors, which allows more lubrication to be provided to
critical points.

Steering Assist

Dual control levers located in front of the operator's seat are
provided for steering the HHN Ride on Power Trowel. The control
levers are linked to two spring loaded cylinders.

Push the left control lever forward and pull the right control lever
backward and the trowel will rotate clockwise on approximately
a center axis. Pull the left control lever backward and push the
right control lever forward and the trowel will rotate
counterclockwise. See Table 3 on page 15 for a complete
description on the control levers directional positioning.

Constant Velocity Joints (CV-Joints)

Constant velocity joints insure the efficient transfer of power to
the drive shaft and maintain the timing of the gearboxes without
any chance of slippage.

Training

For training, please use the “TRAINING CHECKLIST” located
in the front of this manual (Page 5). This checklist is not intended
to be a substitute for proper training but will provide an outline
for an experienced operator to provide training to a new operator.

The HHN Ride-On Power Trowel is equipped with a liquid cooled
31 HP Vanguard gasoline engine. Refer to the engine owner’s
manual for specific instructions regarding engine operation. This
manual is included with the ride-on trowel at the time of shipping
from Whiteman. Please contact your nearest Multiquip Dealer
for a replacement should the original manual disappear.

Blades

The blades of the ride-on power trowel finish the concrete as
they are swirled around the surface. Blades are classified as
combination (10 or 8 inches wide) and finish (6 inches wide).
The HHN ride-on power trowels are equipped with five blades
per rotor equally spaced in a radial pattern and attached to a
vertical rotating shaft by means of a

Seat Assembly

The seat is not installed on the trowel for shipping purposes.
To attach the seat perform the following:

There are two types of seats, depending on what type
of trowel you have. J and B series trowels have slots
on the seat mounting plate that allow fore and aft
adjustment of the seat. H-series trowels have a seat
that is mounted on tracks, similar to an automobile
seat. This seat can be adjusted fore and aft via the
control lever under the front of the seat.

1. Remove the seat from the protective wrapping.

2. Remove the bolts on the bottom of the seat, and place seat
on the seat mounting plate, then insert the bolts through
the holes or slots on the seat mounting plate and tighten.

Battery Setup

This trowel was shipped with a wet charged battery. This battery
may need to be charged for a brief period of time as per the
manufacturer instructions.

CAUTION:

NOTE

Use all safety precautions specified by the
battery manufacturer when working with the
battery.

NOTE

Some models are equipped with
adjustable height handles. Adjust the
height by placing the bolt through the
set of holes that corresponds to the
most comfortable height.

5. Pay close attention to any wires that may be inside the
control handles. DO NOT pinch or cut any wires during
installation.

6. Inside the plastic bag of parts are two knobs for the pitch
control tower cranks. Install these two knobs onto the tower
crank levers.

Starting the Engine

1. With one foot on the ground and the other foot placed on
the trowel's platform, grab hold of any part of the frame and
lift yourself onto the trowel. Then sit down in the operator's
seat.

2. The Whiteman Ride-On Power trowel is equipped with a

kill switch

safety
assembly. Remember the engine will not start unless an
operator is sitting in the operator’s seat. The weight of an
operator depresses an electrical switch, which will allow
the engine to start.

. This switch is located beneath the seat

CAUTION:

NEVER disable or disconnect the kill switch. It

is provided for the operator's safety and injury
may result if it is disabled, disconnected or
improperly maintained.

3. It is recommended that the kill switch be used to stop the
engine after every use. Doing this will verify that the switch
is working properly and presents no danger to the operator.
Remember to turn the key to the “OFF” position after
stopping the machine. Not doing so may drain your units’
battery.

4. The right foot pedal (Figure 7) controls blade and engine
speed. The position of the foot pedal determines the blade
speed. Slow blade speed is obtained by slightly depressing
the pedal. Maximum blade speed is obtained by fully
depressing the pedal.

7. Turn the ignition key clockwise to the (start) position. The

oil

8. Turn ignition key fully clockwise and listen for engine to
start. Once engine has started release ignition key.

9. If the engine fails to start in this manner, consult the engine
owner's manual supplied with the trowel.

10. Test the safety kill switch by standing up briefly. The switch
under the seat should cause the engine to stop. If the kill
switch fails to shut down the engine. Turn off the engine
with the key switch and fix the safety kill switch. See Table
4 (Troubleshooting ) for possible problems.

11. Repeat this section a few times to get fully acquainted with
the engine starting procedure.

Steering

Two control levers located in front of the operator’s seat provide
directional control for the HHN Ride-On Power Trowel. Table 3
(Page 18) illustrates the various directional positions of the
joysticks and their effect on the ride-on trowel.

and charge indicator lights (Figure 8) should be on.

Figure 7. Blade Speed Control Foot Pedal

5. Keep your foot OFF the gas pedal (right foot pedal). If the
engine is cold, adjust the choke but in all circumstances,
start the engine at idle (without touching the gas pedal).

6. Insert the

3. With your right foot quickly depress the right foot pedal
halfway. Notice that the ride-on power trowel begins to move
in a forward direction. Return both joystick controls to their
neutral position to stop forward movement, then remove
your right foot from the right foot pedal.

seat position.

4. Practice holding the machine in one place as you increase
blade speed. When about 75% of maximum blade speed
has been reached, the blade will be moving at proper
finishing speed. The machine may be difficult to keep in
one place. Trying to keep the ride-on trowel stationary is a
good practice for operation.

5. Practice maneuvering the ride-on trowel using the
information listed in Table 3. Try to practice controlled
motions as if you were finishing a slab of concrete. Practice
edging and covering a large area.

6. Try adjusting the pitch of the blades. This can be done with
the ride-on trowel stopped or while the trowel is moving,
whatever feels comfortable. Test the operation of optional
equipment like retardant spray and lights if equipped.

MAINTENANCE PROCEDURES

.

See the engine manual supplied with your machine for
appropriate engine maintenance schedule and
troubleshooting guide for problems.

At the front of the book (Page B) there is a “Daily Pre-Operation
Checklist”. Make copies of this checklist and use it on a daily
basis.

Disconnect spark plug wires and battery cables before
attempting any service or maintenance on the ride-on trowel.

MAINTENANCE SCHEDULE

Daily (8-10 Hours)

NOTE

Checking The Drive Belt

The drive belt needs to be changed as soon as it begins to show
signs of wear. DO NOT reuse a belt under any circumstances.
Indications of excessive belt wear are fraying, squealing when
in use, belts that emit smoke or a burning rubber smell when in
use.

Under normal operating conditions, a drive belt may last
approximately 150 hours. If your trowel is not reaching this kind
of life span for drive belt wear, check the drive belt for proper
pulley alignment and spacing .

To gain access to the drive belt, remove the drive belt guard
cover, then visually inspect the drive belt for signs of damage or
excessive wear. If thedrive belt is worn or damaged, replace the
drive belt.

Installing the Replacement Drive Belt

The HHN trowel is equipped with a replacement drive belt (spare)
carrier (Figure 13), which is mounted on the back-side of the fuel
tank opposite the clutch. Make sure that there is ALWAYS a spare
drive belt in the drive belt carrier before the trowel is placed on a slab
to finish concrete.

1. To add a replacement drive belt for use on the upper and
lower drive pulleys, remove the 2 screws that secure the
spare drive belt carrier.

2. Remove the spare drive belt carrier from the trowel, and
free the replacement drive belt.

3. Slide the replacement drive belt over the upper and lower
pulleys reversing steps 1 thru 5 on page 20.

NOTE

It will be necessary to disconnect the CV-Joint from the
left-side gear box coupler. This means the removal of the
three screws that secure the CV-Joint to the gear box.

Spare Drive Belt Replacement

To replace a spare drive belt, be prepared to disconnect the CV­joint from the left-side gear box.

1. Place the HHN trowel on jack stands, and observe all safety
precautions.

2. Remove the three screws that secure the CV-joint to the
left-side gear box coupler.

3. Once the CV-joint has been separated from the left-side
gearbox, push the CV-joint inward so that a gap exist
between the gearbox and the CV-joint (Figure 13). Slide
the spare V-belt between the gear box coupler and the CV­joint. If any grease or oil is present on the replacement
drive belt, remove it.

4. Place the spare drive belt inside the drive belt carrier, and
secure the spare belt carrier to the back-side of fuel tank.

5. Install the three screws that secure the CV-joint to the left­side gear box coupler.

It may be necessary to disconnect the CV-Joint from the

HHN -31V — MAINTENANCE

The HHN trowel is equipped with a "Torque Converter" which
supplies torque to both the left and right gear boxes.

The function of the a torque converter is to automatically deliver the
correct amount of torque required by the trowel under all load
conditions. This enables the trowel to deliver the necessary torque
for float pan applications and the high rotor speeds required for
burnishing concrete.

The torque converter used in the HHN series trowels is of the
variable pitch pulley type (Figure 14) connected by a drive belt.

Fig. 14. Torque Converter/Variable Pitch Pulley

As shown in Figure 16, centrifugal force pushes the roller arms (see
Figure 17 below) against the ramp plate, forcing moveable face
toward fixed face squeezing belt.

The "Variable Pitch Pulleys" have one

Blade Pitch

Matching Blade Pitch for Both Sets of Blades

Sometimes it may be necessary to match blade pitch between
the two sets of blades. There are some signs that this may be
necessary. For example, the differences in pitch could cause a
noticeable difference in finish quality between the two sets of
blades. Or, the difference in blade pitch could make the machine
difficult to control. This is due to the surface area in contact with
the concrete (the blade set with the greater contact area tends to
stick to the concrete more).

Clutch

This clutch system provides a high pulley ratio (a low gear- so to
speak) to start out and a low pulley ratio ( a high gear- so to
speak) for a high speed operation, with infinite variation between
the two.

This means that it will not be necessary to give
order to "break the blades/pans loose". The machine can slowly
be brought up to speed.

HHN -31V — MAINTENANCE

Blade Pitch Adjustment Procedure

The maintenance adjustment of blade pitch is an adjustment
that is made by a bolt (Figure 19) 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 thrust collar. The goal of adjustment is to promote
consistent blade pitch and finishing quality.

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 or
bouncing motion 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? These
are some of the indications that the blade pitch may need to be
adjusted using the adjustment bolts on the trowel blade finger.

It will be possible to 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. If possible, adjust the low bolt up to the level
of the rest of the bolts. This is the fastest way, but may not always
work. Verify that after adjustment, the blades pitch correctly.

Often times, if the blades are incorrectly adjusted, they will not
be able to pitch flat. This occurs when the adjusting bolts have
been raised too high. Conversely, sometimes the adjusting bolts
are too low and the blades cannot be pitched high enough for
finishing operations.

Changing A Blade

Whiteman recommends that all the blades on the entire machine
be changed at the same time. If only one or some of the blades
are changed at one time, the machine will not finish concrete
consistently and the machine may wobble or bounce.

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. This is important
for ride-on trowels as the two sets of blades counter-rotate.
Lift the machine up, placing blocks under the main guard
ring to support it.

Figure 19. Blade Pitch Adjustment Bolt

The easiest and most consistent way to make this adjustment is
to use the Trowel Arm Adjustment Fixture (P.N. 9177) . 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 adjustment 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 of them is not making contact; some
adjustment will be necessary.

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

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

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

5. Affix the bolts and lock washers.

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

Steering Adjustment

The steering assist adjustment is to be performed only by
qualified service technicians. For HHN steering adjustment
instructions, reference MQ Whiteman service bulletin 200925

Clean-Up

Never allow concrete to harden on the power trowel. Immediately
after use wash any concrete off the trowel with water, be careful
not to spray a hot engine or muffler. An old paint brush or broom
may help loosen any concrete that has started to harden.
