SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNINGRESPIRATORY 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.

Concrete Finishing Techniques
The following steps are intended as a basic guide to machine
operation, and are not to be considered a complete guide to
concrete finishing. We suggest that all operators (experienced
and novice) read “Slabs on Grade” published by the
AmericanConcrete Institute, Detroit, Michigan. Read the
“Training” section of this manual for more information.
Pitching the Blades (Standard Handle)
To pitch the blades upwards using the "Standard" handle,
(Figure 11) simply turn the star-wheel clockwise. Turning the
star wheel counter clockwise will cause the blades to lay flat.

Maneuvering the Trowel
1. Get into the operator’s position behind the handle. With
a secure foothold and a firm grasp on the handle, slowly
increase the engine speed until the desired blade speed
is obtained.
2. Figure 12 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
NEVERplace 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
13) 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.
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 15. Clip-On Float Blade
Float Discs (Optional)
These round discs (Figure 16) 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 13. Combination Blade
Finish Blades (Optional)
These blades (Figure 14) 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 14. Finish Blade
Clip-On Float Blades (Optional)
These blades will clip (Figure 15) onto an existing installed
blade, allowing your finisher to float on “wet” concrete so
that the troweling operation can begin as early as possible.
Figure 16. Float Disk/Pan
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 17) that will
adjust all of the trowel arms consistently. The Trowel Arm
Fixture P/N is 1817.

Ge neral mainten ance practices are cruc ial 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 for scheduled trowel maintenance.
The following procedures, devoted to maintenance, can
prevent serious trowel damage or malfunctioning.
Every
50-60 Hrs
Every
200-300 Hrs
Every
2000-2500 Hrs
Also, examine the V-belt and determine if it is "glazed "
(hard shiny appearance on the sides of the belt). Either of
these two conditions can cause the belt to run hot, which
can weaken it and increase the danger of it breaking.
If the V-belt exhibits any of the above wear conditions
replace the V-belt immediately
GENERAL CLEANLINESS
Clean the trowel daily. Remove all dust and slurry buildup.
If the trowel is steam-cleaned, ensure that lubrication is
accomplished AFTER steam cleaning.
GLAZED
ELECTRIC MOTOR
The electric motor bearing is prelubricated, no further
lubrication or maintenance is required.
V-BELT
Visually examine the V-belt (Figure 18) and determine if it
is full of tiny cracks, frayed, has pieces of rubber missing,
is peeling or otherwise damaged.

BLADE PITCH ADJUSTMENT PROCEDURE
The maintenance adjustment of blade pitch is an adjustment
that is made by a bolt (Figure 19) 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.

Watch for the following indications when determining if
blade pitch adjustments are necessary:
2. Pitch the blades as flat as possible. The pitch
adjustment bolts (Figure 20) 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.
• 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:
1. Place the trowel on a flat, level area free of dirt and
debris.
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.
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.

same clearance between the round of the trowel arm
shaft and the test surface.
Figure 24. Trowel Arm Removal
CHECKING TROWEL ARM STRAIGHTNESS
Trowel arms (Figure 25) 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:

TROWEL ARM LEVER ADJUSTMENT
The easiest and most consistent wASSY. 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:
PAGE 26 — J36E2 ELECTRIC WALK-BEHIND TROWEL • OPERATION AND PARTS MANUAL — REV. #0 (07/24/12)
MAINTENANCE
1. Unscrew the locking bolts on the adjustment fixture and
place the trowel arm (lever attached) into the fixture
channel as shown in Figure 27.
2. Ensure the fixture arm is in the up position.

VARIABLE SPEED PULLEY
General Description
A fixed center distance compound drive consists (Figure 29)
of one cam stabilized automatic variable pulley, one manually
controlled pulley and a standard "V" belt or a variable speed
belt.
The speed adjustment is accomplished by turning the
leadscrew of the manually controlled pulley. As the faces
contract, the belt is forced to a larger diameter in the
manual pulley and consequently to a smaller diameter in
the automatic pulley.
Compound center distance drives may be "C" mounted,
both driving and driven shafts pointed in the same direction,
or "Z" mounted, driving and driven shafts opposed.
The manually controlled pulley must be mounted on the
driver shaft.
DRIVER PULLEY
J
1. Lift trowel just enough to slide pan under blades. Lower
finisher onto pan with blades adjacent to Z-Clips.
2. Rotate blades into position under Z-Clips. Ensure that
the blades are rotated in the direction of travel when
the machine is in operation or use the engine to rotate
the blades into position.
3. Attach the blade tie-downs to the far side of the Z-Clip
brackets with tie-down knobs as shown in Figure 28.
4. Check to make certain that the blade edges are
secured under the Z-Clips and the tie-downs are
secured completely over the edges of the blade bar
before the machine is put back into operation.
LONG-TERM STORAGE
For storage of the trowel for over 30 days, the following is
required:
Clean all external parts of the trowel with a cloth.
Cover the trowel and store in a clean, dry place.

MAINTENANCE
ELECTRIC MOTOR INSTALLATION
1. Locate the electric motor so its shaft is offset from the
driven shaft according to the dimension J for "C" mount
or dimension L minus J for "Z" mount. Make sure the
shafts are parallel.
2. Place both pulleys on the proper shaft and install the
belt with the manually controlled pulley wide open
(minimum speed position). It should not be necessaryto
use force to mount the pulleys.
If they do not slide on easily, examine the shaft for burrs
and check the diameter. The shaft should be of proper
size (+.0000-0005). Too loose a fit between pulley bore
and the shaft can cause vibration, imbalance and
pounding-out of the pulley bore.
3. Align the drive by placing a straight edge along the
outside rim of the automatic pulley and move either
pulley axially on its shaft until the belt edge is parallel
to the straight edge. See Figure 29.
4. Before starting the drive tighten the set screws and
make sure the torque arm is anchored. Install torque
arm guide (anchor) rod through clip on torque arm.
Secure one end of guide rod to a stationary object.
NOTICE
CLEANING: Foreign matter may collect in the moving
parts of the pulley causing them to stick or freeze. If
this occurs, disassemble the pulley (see section on
disassembly) and clean the slide disc bushing and shaft
thoroughly with a solvent. After cleaning, relubricate the
pulley by wiping a film of grease on all bearing surfaces.
DISASSEMBLY
1. Remove the handwheel (Figure 30) from the leadscrew.
Screw in the leadscrew until the front disc comes off
the shaft.
2. The bearing housing will push the lube seal out of
the front disc.
3. The shaft bearing is removed by removing the
retaining ring and pushing against the inside end of
the leadscrew in an arbor press.
4. Remove the disc bearing by pushing against the outer
race of the bearing from the profile end of front disc.
Use extreme care in removing the bearings as they
are easily damaged.
NOTICE
Torque arm must be free to slide over guide rod through
the full range of speed adjustments.
5. Adjust the tension on the leadscrew by tightening
the set screw in the leadscrew nut . If the leadscrew
creeps in operation, more tension is necessary.
6. In order to obtain the full ratio of a compound drive,
the V-belt should bottom on the manually controlled
pulley shaft when it is at the maximum diameter of the
automatic pulley.
If practical, a take-up allowance should be provided for
on either the driver or driven shaft.
However, the allowable tolerance on belt lengths and
the possibility of belt stretch may require an adjustment
of the center distance from that listed.
NOTICE
LUBRICATION: The fixed-center compound drive pulley
has oil impregnated sintered bushings on all bearing
surfaces and under normal operating conditions will not
require lubrication for the life of the pulley. Ball bearings
in the manual control are permanently lubed.
NOTICE
Before the parts are removed, they should be line
marked so they can be reassembled in the same order.
Reassemble all the parts onto the pulley shaft in the
reverse sequence in which they were removed for
placement under the arbor press.

Check that all blades are set at the same
pitch angle as measured at the spider. A fi eld
adjustment tool is available for height adjustment
of the trowel arms. (Contact Parts Dept.)
Check the spider assembly for bent trowel arms.
If one of the arms is even slightly bent, replace it
immediately.
Check fi t of arms in spider. This can be done by
moving the trowel arms up and down. If there is
more than 1/8 inch (3.2 mm) of travel at the tip of
the arm, the spider and arms should be replaced.
Check the fl atness of the thrust collar by rotating
it on the spider. If it varies by more than 0.02 inch
(0.5 mm) replace the thrust collar.
Check the thrust collar by rocking it on the spider.
If it can tilt more than 3/32 inch (2.4 mm) - as
measured at the thrust collar O.D., replace the
thrust collar.
Check the thrust bearing to see that it is spinning
freely. Replace if necessary.
The main output shaft of the gearbox assembly
should be checked for straightness. The main
shaft must run straight and cannot be more than
0.003"" (0.08 mm) out of round at the spider
