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
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
.
Figures 2 and 3 show the location of the controls, indicators and
general maintenance parts. Each control may perform more than
one function. The functions of each control or indicator is on
pages 13 and 14.
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.
