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 Figure 2 and Figure
3) 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
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 spider
assembly.
Figure 2 and Figure 3 show the location of the controls,
indicators and general mainte nance parts. Each control
may perform more than one function.
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 4 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. This checklist is not
intended to be a substitu te for proper training but will
provide an outline for an experienced operator to provide
training to a new operator.
