fuel and chemical exposure Warnings  
Gasoline engine exhaust and some of  
its constituents,and some dust created  
by power sanding, sawing, grinding,  
drillingandotherconstructionactivities  
contains chemicals known to the State  
of California to cause cancer, birth  
defects and other reproductive harm.  
Some examples of these chemicalsare:  
Leadfromlead-basedpaints.  
Crystallinesilicafrombricks.  
Cementandothermasonryproducts.  
Arsenicandchromiumfromchemically  
treatedlumber.  
Your risk from these exposures varies,  
dependingonhowoftenyoudothistype  
of work. To reduce your exposure to  
these chemicals: ALWAYS work in a  
well ventilated area, and work with

silicosis/respiratory Warnings  
WARNING WARNING  
SILICOSIS WARNING  
RESPIRATORY HAZARDS  
Grinding/cutting/drilling of masonry, concrete, metal and  
other materials with silica in their composition may give  
off dust or mists containing crystalline silica. Silica is a  
basic component of sand, quartz, brick clay, granite and  
numerous other minerals and rocks. Repeated and/or  
substantial inhalation of airborne crystalline silica can  
cause serious or fatal respiratory diseases, including  
silicosis. In addition, California and some other  
authorities have listed respirable crystalline silica as a  
substance known to cause cancer. When cutting such  
materials, always follow the respiratory precautions  
mentioned above.  
Grinding/cutting/drilling of masonry, concrete, metal and  
other materials can generate dust, mists and fumes  
containing chemicals known to cause serious or fatal  
injury or illness, such as respiratory disease, cancer,  
birth defects or other reproductive harm. If you are  
unfamiliar with the risks associated with the particular  
process and/or material being cut or the composition of  
the tool being used, review the material safety data  
sheet and/or consult your employer, the material  
manufacturer/supplier, governmental agencies such as  
OSHA and NIOSH and other sources on hazardous  
materials. California and some other authorities, for  
instance, have published lists of substances known to  
cause cancer, reproductive toxicity, or other harmful  
effects.  
Control dust, mist and fumes at the source where  
possible. In this regard use good work practices and  
follow the recommendations of the manufacturers or  
suppliers, OSHA/NIOSH, and occupational and trade  
associations. Water should be used for dust  
suppression when wet cutting is feasible. When the  
hazards from inhalation of dust, mists and fumes cannot  
be eliminated, the operator and any bystanders should  
always wear a respirator approved by NIOSH/MSHA for  
the materials being used.

general information  
gEarbOx  
INTeNDeD USe  
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).  
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  
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.  
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.  
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.  
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.  
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.  
Before using your trowel, test it on a flat watered down  
section of finished concrete that is free of any debris and  
other objects.  
CeNTRIFUgaL SafETy STOp SwiTch  
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.  
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  
ENgiNE  
CaUTION  
This trowel is equipped with a SUBARU 9.0 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.  
NEVER attempt to lift the trowel by yourself. ALWAYS get  
the assistance of another person to help lift the trowel.  
TraiNiNg  
Forpropertraining, pleaseusetheTraiNiNgchEcKliST”  
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.  
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.

aSSembLy aND INSTaLLaTION  
NOTICE  
Before the trowel can be put into operation there are some  
components that must be installed before the trowel can  
be used.This section provides general instructions on how  
to install those components. Instruction sheet P/N 20485  
provides further details for the handle assembly.  
If additional handle height adjustment is desired, a  
handle wedge kit can be purchased for your trowel by  
ordering P/N 2576 from your Multiquip dealer.  
These wedges are placed between the handle and the  
gearbox to adjust the operating height of the handle.  
This kit comes complete with wedges, new bolts and  
installation instructions. This will move your operating  
handle position up or down approximately 3” (76 mm).

Clip-On Float blades (Optional)  
NOTICE  
These blades will clip (Figure 38) onto an existing installed  
blade, allowing your finisher to float on “wet” concrete so  
that the troweling operation can begin as early as possible.  
These blades are easily removable, so that after the floating  
operation, when the concrete is sufficiently cured, they can  
be removed to expose the finish blades for continued  
troweling.  
Trowel blades should be changed when they fail to finish  
concrete in a satisfactory manner.  
Blades are a vital part of finishing concrete. This trowel,  
or finisher, has been designed to finish concrete and the  
blades are built to stringent quality standards out of the  
finest steel.  
If you need replacement blades, consult the parts list in  
this manual for part numbers and order them from your  
Multiquip parts dealer or importer.  
combo blades  
This trowel is equipped with combination float/finish (Figure  
36) blades as original equipment.These blades have been  
designed for optimum performance in both the floating and  
finishing operations.These blades are versatile and should  
take care of most troweling needs.  
Figure 38. Clip-On Float Blade  
Float Discs (Optional)  
These round discs (Figure 39) attach to the spiders and  
allow the machine to “float” on “wet” concrete. The disc  
design allows early floating and easy movement from wet  
to dry areas. They are also very effective in embedding  
large aggregates and surface hardeners.  
Figure 36. Combination Blade  
Finish blades (Optional)  
These blades (Figure 37) have been specifically designed  
for finish operations with this trowel. They will provide a  
premium surface finishing capability from your trowel.They  
should only be used after the concrete has set to the point  
where the trowel does not sink into the concrete when  
placed on it.

maintenance  
General maintenance practices are crucial to the  
performance and longevity of your trowel. This equipment  
requires routine cleaning, blade and trowel arm inspection,  
lubrication and V-belt inspection for wear and damage.  
Reference Table 5 and Table 6 for scheduled engine and  
trowel maintenance.  
Engine air cleaner  
daNgEr  
dO NOT use gasoline or low flash point  
solvents for cleaning the air cleaner, the  
possibility exists of fire or explosion which  
can cause damage to the equipment and  
severe bodily harm or even dEaTh!  
The following procedures, devoted to maintenance, can  
prevent serious trowel damage or malfunctioning.  
CaUTION

Clean the spark arrester every 6 months or 100 hours.  
The maintenance adjustment of blade pitch is an adjustment  
that is made by a bolt (Figure 48) on the arm of the trowel  
arm lever. This bolt is the contact point of the trowel arm  
lever to the lower wear plate on the thrust collar. The goal  
of the adjustment is to promote consistent blade pitch and  
finishing quality. Adjustments are made by tightening or  
loosening the blade pitch adjustment bolt.  
1. Remove the 4 mm screw (3) from the exhaust deflector,  
then remove the deflector. See Figure 46.  
2. Remove the 5 mm screw (4) from the muffler protector,  
then remove the muffler protector.

Does the machine have a perceptible rolling or  
bouncing motion when in use?  
4. Carefully remove carbon deposits from the spark  
arrester screen (Figure 47) with a wire brush.  
Look at the machine while it is running, do the guard  
rings “rock up and down” relative to the ground?

If it is determined that blade pitch adjustments are required  
do the following:  
1. Place the trowel on a flat, level area free of dirt and  
debris.  
NOTICE  
SPARK  
ARRESTER  
SCREEN  
Before any blade pitch adjustments can be made it  
is essential to have a clean level area free of dirt and  
debris to test the trowel. Any unlevel spots in the floor  
or debris under the trowel blades will give an incorrect  
perception of adjustment. Ideally, a 5 x 5 ft. (1.5 x 1.5  
meter), three-quarter inch (19 mm) thick flaT steel  
plate should be used for testing.

2. Pitch the blades as flat as possible. The pitch  
adjustment bolts (Figure 49) should all barely make  
contact (0.10 inch max.clearance) with the lower wear  
plate on the spider. All pitch alignment bolts should  
be spaced the same distance from the lower wear plate.  
If one is not making contact, adjustment will be  
necessary.

It is recommended that all the blades on the trowel  
are changed at the same time. If only one or some of the  
blades are changed, the machine will not finish concrete  
consistently and the machine may wobble or bounce.  
1. Each trowel arm is held in place at the spider plate  
by a hex head bolt (zerk grease fitting) and a roll  
pin. Remove both the hex head bolt and the roll  
pin (Figure 53) from the spider plate.  
Perform the following procedure when changing blades:  
Please note the blade orientation on the trowel arm before  
removing.  
2. Remove the trowel arm from the spider plate.  
3. Should the trowel arm inserts ( bushing ) come out with  
the trowel arm, remove the bushing from the trowel arm  
and set aside in a safe place. If the bushing is retained  
inside the spider plate, carefully remove the bushing  
1. Lift the trowel up, placing blocks under the main guard  
ring to support it.  
2. Remove the bolts and lock washers from all the towel  
arms, and then remove the blades as shown in  
Figure 52.

CHeCKINgTROWeL aRm STRaIgHTNeSS  
TROWeL aRm LeveR aDjUSTmeNT  
Trowel arms (Figure 54) can be damaged by rough  
handling, such as dropping the trowel on the pad, or by  
striking exposed plumbing, forms, or rebar while in  
operation. A bent trowel arm will not allow the trowel to  
operate in a smooth fluid rotation. If bent trowel arms are  
suspect, check for flatness as follows:  
The easiest and most consistent way to adjust the trowel  
arm lever is to use the Trowel Arm Adjustment Fixture  
(P.N. 1817).  
As each trowel arm is locked into the fixture, the arm bolt  
is adjusted to where it contacts a stop on the fixture. This  
will consistently adjust all of the trowel arms, keeping the  
finisher as flat and evenly pitched as possible.
