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.

brief explanation of each control or component.

1. Handle Bar Pad — Foam rubber pad that protects the
body when coming in contact with handle bar.

2. Vibratory Handle Bar — Installed rubber shock
mounts/isolators reduce vibration when the trowel is
operating.

3. Hand Grips — When maneuvering of the trowel is
required, ALWAYS place both hands on each grip
to operate the trowel. Replace hand grips when they
become worn or damaged.

4. Star Wheel Pitch Knob (4-Blade) — To adjust the pitch
of the blades, rotate the star wheel clockwise to pitch
blades upwards. Rotate star wheel counterclockwise
to pitch blades flat (no pitch).

Figure 2. Trowel Components

5. Star Wheel Pitch Knob (Fresno) — To adjust the
pitch of the fresno blade upward, rotate the star wheel
clockwise. Rotate star wheel counterclockwise to pitch
blade flat (no pitch).

6. Blades — This trowel is equipped with combination
blades. These blades are versatile and should take
care of most troweling needs. In addition, float discs
can be attached to the trowel arms that will allow the
trowel to float on "wet" concrete.

7. Guard Ring — NEVER put hands or feet inside guard
ring while the machine is running.

8. Trowel Arm — NEVER operate the trowel with a bent,
broken or out of adjustment trowel arm. If the blades

ENGINE COMPONENTS

INITIAL SERVICING

The engine (Figure 4) must be checked for proper
lubrication and filled with fuel prior to operation. Refer to the
manufacturer's engine manual for instructions and details
of operation and servicing.

1. Fuel Filler Cap – Remove this cap to add unleaded
gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT over fill.

DANGER

Add fuel to the tank only when the engine
is stopped and has had an opportunity to
cool down. In the event of a fuel spill, DO
NOT attempt to start the engine until the
fuel residue has been completely wiped up
and the area surrounding the engine is dry.

2. Throttle Lever – Used to adjust engine RPM speed.
This lever is connect to the throttle lever cable located
on the handle bars. Reference throttle cable installation
procedure in this manual.

3. Recoil Starter (pull rope) – Manual-starting method.
Pull the starter grip until resistance is felt, then pull
briskly and smoothly.

4. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to
stop the flow of fuel.

5. Choke Lever – Used in the starting of a cold engine,
or in cold weather conditions. The choke enriches the
fuel mixture.

Figure 4. Engine Controls and Components

6. Air Cleaner – Prevents dirt and other debris from
entering the fuel system. Remove wing-nut on top of
air filter canister to gain access to filter element.

NOTICE

Operating the engine without an air filter, with a
damaged air filter, or a filter in need of replacement
will allow dirt to enter the engine, causing rapid engine
wear.

7. Spark Plug – Provides spark to the ignition system.
Set spark plug gap according to engine manufacturer's
instructions. Clean spark plug once a week.

8. Muffler – Used to reduce noise and emissions. NEVER
touch when hot!

9. Fuel Tank – Fill with unleaded gasoline. Refer to Table
3 for fuel tank capacity. For additional information refer
to Honda engine owner's manual.

10. Dipstick/Oil Filler Cap – Remove this cap to determine
if the engine oil is low. Add oil through this filler port as
recommended in Table 4.

11. Oil Drain Plug – Remove this plug to remove oil from
the engine's crankcase.

12. Engine ON/OFF Switch – ON position permits engine
starting, OFF position stops engine operation.

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 32) 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

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.

NOTICE

Figure 32. Lifting the Trowel

NEVER lift the trowel to unnecessary heights. DO NOT

OPERATION

Maneuvering the Trowel

1. Get into the operator’s position behind the handlebar.
With a secure foothold and a firm grasp on the
handlebar, slowly increase the engine speed until the
desired blade speed is obtained.

2. Figure 45 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 or laterally. Be careful when moving
backwards or laterally so that hazards can be avoided.
The best way to get accustomed to the trowel is
repeated use.

4. After the initial troweling pass, bring the trowel to a
clean troweled section.

5. Rotate the winch clockwise to lower the fresno blade
and brush to the troweling surface.

6. Slowly walk backwards or laterally to guide the trowel in
a straight path. Make sure the fresno blade and brush
follow the path of the trowel. This will cover all footprints
and troweling marks on wet surfaces.

7. Rotate the winch counterclockwise to raise the fresno
blade and brush at the end of the troweling path. If
troweling laterally, rotate the boom to the opposite side
between passes before beginning a new pass.

8. Repeat Steps 4-7 until the troweling surface is
completely finished.

CAUTION

NEVER place your feet or hands inside the guard rings

while starting or operating this equipment.

CAUTION

ALWAYS keep clear of rotating or moving parts while

operating this equipment.

To move the trowel to the operator’s
left, lift up on the handle, to move the
trowel to the right push down on the
handle.

Remember! that if you let go
of the trowel, just step away
and let the trowel come to a
complete STOP before trying
to recover the trowel.

Remember! that if you let go
of the clutch lever, just step away
as the trowel will stop immediately.

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 49) 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 51) 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 51. Clip-On Float Blade

Float Discs (Optional)

These round discs (Figure 52) 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 49. Combination Blade

Finish Blades (Optional)

These blades (Figure 50) 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.

OPTIONS

Trowel Arm Adjustment Tool (Optional)

If blades show uneven wear patterns or some tend to
wear out faster than others, the trowel arms may need to
be adjusted. A special tool is available (Figure 53) that will
adjust all of the trowel arms consistently. The Trowel Arm
Fixture P/N is 1817.

Figure 53. Trowel Arm Adjustment Fixture

FRESNO BRUSHES

NOTICE

Fresno brushes should be changed when they fail to
finish concrete in a satisfactory manner.

Fresno brushes are a vital part of finishing concrete. The
fresno brush is designed to finish concrete with a textured,
or decorative, look using the sides of the brush bristles, not
the ends. There are three different color-coded, textured
(stiffness) brushes compatible with this trowel unit: soft
(black), medium (orange), stiff (green).

If you need a replacement brush, or want a different
finished look to the troweling surface, consult the parts list
in this manual for part numbers and order them from your
Multiquip parts dealer or importer.

INSIDE OUT

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.

The following procedures, devoted to maintenance, can
prevent serious trowel damage or malfunctioning.

NOTICE

Reference HONDA engine manual supplied with your
trowel for more detailed engine maintenance and
troubleshooting.

CAUTION

ALWAYS allow the engine to cool before

servicing. NEVER attempt any maintenance
work on a hot engine.

CAUTION

ALWAYS disconnect the spark plug wire from the spark

plug and secure away from the engine before performing
maintenance or adjustments on the machine.

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!

CAUTION

Wear protective equipment such as
approved safety glasses or face shields
and dust masks or respirators when

4-BLADE PITCH ADJUSTMENT PROCEDURE

The maintenance adjustment of blade pitch is an adjustment
that is made by a bolt (Figure 60) 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.

Figure 60. Blade Pitch Adjustment Bolt

Watch for the following indications when determining if
blade pitch adjustments are necessary:

• Is the machine wearing out blades unevenly, (i.e. one
blade is completely worn out while the others look
new)?

• Does the machine have a perceptible rolling or
bouncing motion when in use?

• 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:

NOTICE

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 61) 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.

3. Adjust the “high” bolts down to the level of the one that
is not touching, or adjust the “low” bolt up to the level
of the higher ones. If possible, adjust the low bolt up
to the level of the rest of the bolts. This is the fastest
way, but may not always work. Verify after adjustment
the blades pitch correctly.

4. Blades that are incorrectly adjusted often will not be
able to pitch flat. This can occur if the adjusting bolts
are raised too high. Conversely, adjusting bolts that
are too low will not allow the blades to be pitched high
enough for finishing operations.

5. If, after making blade pitch adjustments the machine
is still finishing poorly, blades, trowel arms, and trowel
arm bushings may be suspect and should be looked
at for adjustment, wear, or damage.

TROWEL ARM LEVER ADJUSTMENT

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.

This fixture will allow consistent adjustment of the trowel
arm lever. It comes with all the hardware necessary to
properly accomplish this maintenance and instructions on
how to properly utilize this tool. Adjusting the trowel arm
lever without a fixture requires a special talent.

Perform the following procedure when adjusting the trowel
arm lever:

1. Unscrew the locking bolts on the adjustment fixture and
place the trowel arm (lever attached) into the fixture
channel as shown in Figure 68.

2. Ensure the fixture arm is in the up position.

3. A thin shim may be required to cover the blade holes on
the trowel arm. Make sure to align the trowel adjustment
bolt with the fixture adjustment bolt.
