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.

CA4HC TROWEL— SAFETY MESSAGE ALERT SYMBOLS
FOR YOUR SAFETY AND THE SAFETY OF OTHERS!
Safety precautions should be followed at all times when operating
this equipment. Failure to read and understand and comply with
the Safety Messages and Operating Instructions could result in
injury to yourself and others.
This Owner's Manual has been developed to provide complete
instructions for the safe and
efficient operation of the MQ

information, please refer to the
engine manufacturer's
instructions for data relative to its
safe operation.
HAZARD SYMBOLS
SAFETY MESSAGE ALERT SYMBOLS
The three (3) Safety Messages shown below will inform you
about potential hazards that could injure you or others. The
Safety Messages specifically address the level of exposure to
the operator, and are preceded by one of three words: DANGER,
WARNING, or CAUTION.
Lethal Exhaust Gases
Engine exhaust gases contain poisonous
carbon monoxide. This gas is colorless and
odorless, and can cause death if inhaled.
NEVER operate this equipment in a confined
area or enclosed structure that does not
provide ample free flow air.
Explosive Fuel
Gasoline is extremely flammable, and its
vapors can cause an explosion if ignited. DO
NOT start the engine near spilled fuel or
combustible fluids. DO NOT fill the fuel tank
while the engine is running or hot. DO NOT
overfill tank, since spilled fuel could ignite if it
comes into contact with hot engine parts or
sparks from the ignition system. Store fuel in
approved containers, in well-ventilated areas
and away from sparks and flames. NEVER
use fuel as a cleaning agent.

. Listed below is a brief explanation of
each control or component
1. Standard Handle – Employs a "starwheel" for manually
adjusting blade pitch.
2. Foldable Quick Pitch Handle – Employs a lever handle
to quickly adjust blade pitch. Handle folds for storage.
3. Throttle w/ "Kill" Switch – Uses an integrated "kill" switch.
4. Safety Switch – Centrifugal safety switch shuts the engine
off in a "runaway" situation. (Standard Handle)
5. Throttle Control Lever – Controls the speed of the engine.
Move the hand lever towards the operator to increase
engine speed (high), away from the operator to decrease
engine speed (low).
6. Hand Grip/Handle Bar – When operating the trowel, place
both hands on each grip to maneuver the trowel. Replace
hand grips when they become worn or damaged.
7. Engine – Honda GX120 4 H.P. gasoline engine.
8. Pitch Adjust-Standard Handle - Turn clockwise or
counterclockwise to adjust blade pitch.
9. Quick Pitch Handle – Pivots back and forth to adjust blade
pitch.
10. Guard Ring – Helps protect the rotating blades from
damage and helps protect the operator from injury. NEVER
put hands or feet inside the guard ring when engine is
running. NEVER attempt to lift the trowel by the guard ring.
11. Trowel Arm – Provides attachment points for the blades. If
the blades show uneven wear patterns or some blades
wear out faster than others, the trowel arm may need to be
replaced.
12. Blades – This trowel is equipped with special combination
blades. Designed specifically for edging.
13. V-Belt Cover – Remove cover to gain access to the V-belt.
14. Lifting Bale – Provides lifting point for safe lifting of trowel.
15. Thumbwheel Adjuster – Use to adjust throttle cable.
16. Tee Handle – Loosen to fold handle.
17. Trigger Lock – Use to lock blade pitch position.
18. "Kill" Switch – Integrated into Quick Pitch Handle.
19. Throttle Lever Idle Detent – Pressed in, the detent will
hold the lever away from the "kill" switch, allowing the
engine to run at idle.
20. Quick Pitch Latching Bolt – Provides secure positioning
of pitch handle into slotted pitch comb.

Figure 4. Honda GX120 Engine Controls and 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 & details of operation and servicing. The
engine shown above is a HONDA engine, operation for other
types of engines may vary somewhat.
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
Adding fuel to the tank should be done 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.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop
the flow of fuel.
6. Choke Lever – Used in the starting of a cold engine, or in
cold weather conditions. The choke enriches the fuel
mixture.
7. Air Cleaner – Prevents dirt and other debris from entering
the fuel system. Remove wing-nut on top of air filter
cannister to gain access to filter element.
NOTE
8. Spark Plug – Provides spark to the ignition system. Set
spark plug gap according to engine manufacturer's
instructions. Clean spark plug once a week.
9. Muffler – Used to reduce noise and emissions.
10. Fuel Tank – Holds unleaded gasoline. For additional
information refer to engine owner's manual.
11
13
12
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.

11. Oil Drain Plug – Remove this plug to remove oil from the
engine's crankcase.
12. 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.
13. Output Shaft – Drive power is transferred from the engine
output shaft to the gearbox via a V-Belt pulley drive system.
CA4HC TROWEL— HANDLE ASSEMBLIES
Assembly and Installation
Before the trowel can be put into operation there are some
components that must be installed before the trowel can be used.

2. Remove any nuts from the pitch cable end. Insert the cable
through the yoke eyelet, (Figure 11). Thread the conical
nut up to the eyelet first. Tighten the conical nut by hand to
remove all the slack from the cable.
3. Thread the brass locking nut up to the conical nut. Use a
wrench to tighten the conical nut up against the yoke boss.
This will lock the cable in place. Use a wrench to tighten up
the brass nut up against the yoke boss.

2. Clean the trowel, removing dirt and dust, particularly the
engine cooling air inlet, carburetor and air cleaner.
3. Check the air filter for dirt and dust. If air filter is dirty, replace
air filter with a new one as required.
4. Check carburetor for external dirt and dust. Clean with dry
compressed air.
5. Check fastening nuts and bolts for tightness.
Engine Oil Check
1. To check the engine oil level, place the trowel on secure
level ground with the engine stopped.
2. Remove the filler dipstick from the engine oil filler hole
(Figure 13) and wipe clean.
3. Insert and remove the dipstick without screwing it into the filler
neck. Check the oil level shown on the dipstick.
