HHNG5 RIDE-ON POWER TROWEL
FAMILIARIZATION
This Ride-On Power Trowel is designed for the floating and
finishing of concrete slabs.
Take a walk around your trowel. Take notice of all the major
components (see Figure 5 and Figure 6) like the engine,
blades, air cleaner, fuel system, fuel shut-off valve, ignition
switch, etc. Ensure engine and gearbox lubricant levels are
within proper operating range.
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 trowel.
Look at the operator control levers. Grasp the control levers
and move them around a bit. Observe how moving the
control levers causes the gearboxes and frame to move.
Notice the foot pedal which controls the engine and blade
speed. Also take a look at the main driveline of the trowel.
Take note and reference the drive belt alignment—this is
the way the belt should be aligned when adjusted properly.
Before using your 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
This trowel is equipped with a Briggs and Stratton Vanguard
air-cooled, V-twin big block, 35 hp, gasoline engine. Refer
to the engine owner's manual for specific instructions
regarding engine operation. This manual is included with the
trowel at the time of shipping. Please contact your nearest
Multiquip dealer should a replacement manual be required.
Blades
The blades of the trowel finish the concrete as they are
swirled around the surface. Blades are classified as
combination (10 or 8 inches wide) or finish (6 inches wide).
This trowel is 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.

GENERAL INFORMATION

Twin Pitch Control™
The Twin Pitch™ control feature allows the operator to
simultaneously control the pitch of both rotors with minimal
effort, yet still allows for individual pitch control.
Helical Gearboxes
This trowel is designed with two separate helical gearbox
assemblies that are enclosed in rugged cast aluminum
gear cases.
Steering
Dual control levers located in front of the operator's seat
are provided for steering this trowel. The control levers are
linked to two spring-loaded cylinders. In addition, a steering
assist feature has been provided to make controlling of
the trowel easier especially when float pans are installed.
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 8 for
a complete description of the control levers' directional
positioning.
Contstant Velocity Joints (CV-Joints)
Constant velocity joints ensure the efficient transfer of
power to the drive shaft and maintain the timing of the
gearboxes without any chance of slippage.
Continuously Variable Transmission (CVT)
A Continuously Variable Transmission (CVT) has been
installed to obtain maximum drive torque.
This is accomplished by continually adjusting the drive
ratio to obtain optimum torque and speed during all phases
of finishing from low speed/high torque to high speed
burnishing.
