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 chemicals are:
Leadfromlead-basedpaints.
Crystallinesilicafrombricks.
Cementandothermasonryproducts.
Arsenicandchromiumfromchemically
treatedlumber.
Your risk from these exposures varies,
dependingonhowoftenyoudo this type
of work. To reduce your exposure to
these chemicals: work in aALWAYS
well ventilated area, and work with
approved safety equipment, suchas
dust masks that are specially designed
to filter out microscopic particles.

SILICOSIS/RESPIRATORY WARNINGS
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.
WARNING
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
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 and Figure 3) 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.
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.
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 a HONDA 5.5 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.
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.

OPERATION
Operation
This section is intended to assist the operator with the initial
start-up of the walk-behind trowel. It is extremely important
that this section be read carefully before attempting to use
the trowel in the field. DO NOT use your trowel until this
section is thoroughly understood.
Lifting the Trowel Onto a Slab
Extra care should be taken when lifting the trowel off the
ground. Serious damage to the machine or personal injury
could be caused by dropping a trowel.
WARNING
NEVER attempt to lift this machine alone. NEVER lift
the trowel by the guard ring as it may rotate and cause
injury.
ALWAYS make certain the handle is secure and use
only the manufacturer's approved lifting point. The
trowel may be lifted at the center lifting bale by crane
or other lifting device of adequate capacity.
Lifting Bale
The lift bale provides an optimal lift point for lifting the trowel.
When lifting the trowel onto a concrete slab, attach a chain
or rope to the lifting bale. Make sure the lifting device has
adequate lifting capacity to lift the trowel.
Using a crane or forklift (Figure 25) to lift the trowel is highly
recommended, and is perfectly safe for the trowel. ALWAYS
use extra care when lifting the trowel off the ground.
LIFT
NOTICE
DO NOT attempt to operate the trowel until the Safety,
General Information and Inspection sections of this
manual have been read and thoroughly understood.
NOTICE
The trowel is heavy and awkward to move around. Use
proper heavy lifting procedures and DO NOT lift the
trowel by the guard rings.
Figure 25. Lifting the Trowel
NEVER lift the trowel to unnecessary heights. DO NOT
stand underneath the trowel while it is being lifted. Serious
damage to the machine or personal injury could be caused
by dropping a trowel.

OPERATION
Maneuvering the Trowel
1. Get into the operator’s position behind the handle. With
a secure foothold and a firm grasp on the handle and
clutch levers, slowly increase the engine speed until the
desired blade speed is obtained.
2. Figure 36 below illustrates a typical walk-behind trowel
application. Practice maneuvering the trowel. The trick
is to let the trowel do the work.
3. Continue to practice maneuvering the trowel. Try to
practice as if you were finishing a slab of concrete.
Practice edging and covering a large area.
Remember a good finishing technique is to work
backwards. Be careful when moving backwards so
that hazards can be avoided. The best way to get
accustomed to the trowel is repeated use.
CAUTION
NEVER place your feet or hands inside the guard rings
while starting or operating this equipment.

OPTIONS
NOTICE
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 40) 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.
Clip-On Float Blades (Optional)
These blades will clip (Figure 42) 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.
Figure 42. Clip-On Float Blade
Float Discs (Optional)
These round discs (Figure 43) 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 40. Combination Blade
Finish Blades (Optional)
These blades (Figure 41) 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.
Figure 41. Finish Blade
Figure 43. Float Disc/Pan
NOTICE
For optimum panning performance blade speed must
be changed. Use Low Speed Kit. Reference Engine
and Clutch Assembly in parts section of this manual.
