HTH — GENERAL INFORMATION
HTH RIDE-ON TROWEL FAMILIARIZATION
The HTH series Ride-On Power Trowels are designed for the
floating and finishing of concrete slabs.
Take a walk around the HTH Ride-On Power Trowel. Take notice
of all the entire major components (see Figures 2 and 3, Page
11) like the engine, blades, pitch towers, air cleaner, ignition
switch etc. Check that there is always oil in the engine, and
hydraulic oil in the hydraulic oil reservoir.
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 HTH Ride-On Power Trowel.
Before using your HTH 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 HTH Ride-On Power Trowel is available with either a
standard 31 HP Vanguard gas engine or 38 HP Kubota diesel
engine. Refer to the engine owner’s manual for specific instruc-
tions 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
float (10 or 8 inches wide), and finish (6 inches wide). The HTH
is equipped with either four or five blades per rotor equally
spaced in a radial pattern and attached to vertical rotating shaft
by means of a spider assembly.
Hydraulic Motor
Independent hydraulic drive motors are coupled to the engine-
powered hydrostatic pumps. Each motor drives a spider as-
sembly.
Hydraulic Steering
Dual joystick controls located to the left and right of the operator
are provided for steering the HTH-Ride on Power Trowel. The
joysticks are linked to three hydraulic steering cylinders located
within the frame of the machine. When the right side steering
joystick is moved either forward or backward it will cause that
side of the ride-on power trowel to move in either a forward or
reverse direction. Moving the same joystick left or right causes
the trowel to move in either the left or right direction.
When the left side steering joystick is moved, it will cause the
left side of the ride-on trowel to travel in either a forward or
reverse direction.
Hydraulic Pump
Delivers a continuous controlled flow of hydraulic fluid to the
hydraulic motors.
Training
For proper training, please use the “TRAINING CHECKLIST”
located in the front of this manual(Page A). This checklist will
provide an outline for an experienced operator to provide train-
ing to a new operator.
