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 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.
FRESNO BLADE
The fresno blade follows the path of the trowel and four
combination blades as they are rotated around the troweling
surface. This trowel comes equipped with a single fresno
screed blade (5 in./127 mm wide, 48 in/1,219.2 mm long)
that is either raised or lowered via a winch crank handle.
FRESNO BRUSH
The fresno brush follows the path of the trowel,
fresno blade, and four combination blades to provide a
decorative/textured finish to the troweling surface. The
fresno brush is designed to follow the path of the fresno
blade in a floating, or loose, configuration.
The floating configuration allows the fresno brush to
independently match the operator's troweling preferences
without having to manually pitch the brush relative to the
troweling surface for each pass.
PAGE 14 — PRO46 SERIES WALK-BEHIND TROWEL • OPERATION AND PARTS MANUAL — REV. #1 (8/20/15)
MECHANICAL BOOM
The mechanical boom is mounted in front of the trowel
unit and supports the fresno brush, fresno blade, and plated
weight(s). The boom raises and lowers the brush and blade
via the hand crank winch, and has 180° range of lateral
motion which is adjustable based on operator's preference
and troweling surface.
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.
