PAGE 14 — CA4HM WALK-BEHIND TROWEL — OPERATION MANUAL — REV. #3 (10/28/10)
CA4HM Trowel Familiarization
This walk-behind trowel is designed for the
floating
and
finishing
of concrete slabs.
Take a walk around the trowel. Take notice of all the major
components (see Figure 2) like the engine, blades, Quick Pitch™
handle, clutch lever, etc. Check that there is always oil in the
engine.
Read
all the safety instructions carefully. Safety instructions will
be found throughout this manual and on the trowel. Keep all
safety information in good, readable condition. Operators should
be well trained on the operation and maintenance of the trowel.
Before using your trowel, test it on a flat watered down section of
finished concrete that is free of any debris and other objects.
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. In addition you will understand how the trowel handles
under actual conditions.
Engine
This trowel is available with an 4 HP
HONDA
gasoline engine.
Refer to the engine owner’s manual for instructions regarding
the operation and maintenance of your engine. Please contact
your nearest Multiquip Dealer for a replacement should the
original manual disappear or otherwise become unusable.
Training
For proper training, please use the “
TRAINING CHECKLIST
”
located in the front of this manual (Page 8). This checklist will
provide an outline for an experienced operator to provide training
to a new operator
Blades
The blades of the trowel finish the concrete as they are rotated
around the surface. This trowel comes equipped with four
combination
(8 in./203mm wide)
blades
per rotor equally
spaced in a radial pattern and attached to vertical rotating
shaft by means of a
spider assembly
.
Manual Clutch
In the event of a trowel runaway condition (operator releases
the handle), a
manual clutch
will stop the engine and bring
the trowel to a halt.
Drive System
Power is transferred from the engine to the gearbox input shaft
via a V-belt pulley drive system. The pulley engages using a
manual clutch. See Parts section of this manual.
Gearbox
The
gearbox
is located beneath the engine and transfers power
to the
spider
assembly. The gearbox controls the rotational speed
of the trowel and is equipped with two shafts (input and output).
Guard Ring
This unit is equipped with a special rotating guard ring. It is
designed to allow the operator to run the machine alongside
walls, pipes, and obstructions without marring the surface.
Operate the CA4HM Trowel, tools and components in
accordance with the manufacturer's instructions. Use of any
other tools for stated operation is considered contrary to
designated use. The risk of such use lies entirely with the user.
The manufacturer cannot be held liable for damages as a result
of misuse.
Intended Use
Spider
The vertical output shaft of the gearbox connects to a cast hub
called the
spider
. The spider has 4 arms that extend outward
that are used for attachment of blades or other accessories.
Remember as the gearbox output shaft rotates so does the spider
assembly.
