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.
