PAGE 14 — BS46H SERIES WALK-BEHIND TROWEL • OPERATION AND PARTS MANUAL — REV. #3 (06/02/16)
GENERAL INFORMATION
INTENDED USE
Operate this 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.
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 (Figure 2) like the engine, blades, steering
handle, kill switch, gearbox, 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 equipped with either a HONDA 9 or 11 HP
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.
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 centrifugal clutch. See parts section of this manual
for a breakdown of the drive system.
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).
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.
GUARD RING
This unit is equipped with a safety guard ring. It is designed
to help protect items from coming into contact with the
rotating blades while the trowel is in operation.
BLADES
The blades of the trowel finish the concrete as they are
rotated around the surface. This trowel comes equipped
with four
combination
blades
(8 in./203 mm wide) per
rotor equally spaced in a radial pattern and attached to a
vertical rotating shaft by means of a spider assembly.
CENTRIFUGAL
SAFETY STOP SWITCH
In the event of a trowel runaway condition (operator
releases handlebars during operation), the centrifugal
safety stop switch will stop the engine and bring the trowel
to a halt
TRAINING
For proper training, please use the “
TRAINING CHECKLIST
”
form located in the front of this manual. This checklist will
provide an outline for an experienced operator to provide
training to a new operator.
CAUTION
NEVER
attempt to lift the trowel by yourself.
ALWAYS
get
the assistance of another person to help lift the trowel.
