Choose correct blade type and attach blades to trowel arms. Do not mix oat or nish blades with
combination blades.
CAUTION: Do not attempt to adjust handle height on the trowel while it is running.
WARNING: Allow the mufer to cool before cleaning or servicing the machine. A hot mufer could
ignite the fuel and start a re.
WARNING: Personnel other than the trowel operator should not be allowed in the work area, as severe
injury can occur from contact with operating trowel blades.
MAINTENANCE The chart below lists basic machine and engine maintenance.
Perform initially after rst 20 hours of operation.
In the interests of environmental protection, place a plastic sheet and a container under the machine
to collect any liquid which drains off. Dispose of this liquid in accordance with environmental protection
legislation.

MAINTENANCE
ENGINE OIL:
Drain oil while the engine is still warm.
Remove the oil ll plug and drain cap to drain oil.
Install drain cap.
Fill the engine crankcase with recommended oil up to the level of the plug opening.
AIR CLEANER:
Service air cleaner frequently to prevent carburetor malfunction. NEVER run engine without air cleaner.
Severe engine damage will occur. NEVER use gasoline or other types of low ash point solvents for
cleaning the air cleaner. A re or explosion could result.
Remove air cleaner cover. Remove both elements and inspect them for holes or tears. Replace
damaged elements.
Wash foam element (b) in solution of mild detergent and warm water. Rinse thoroughly in clean water.
Allow element to dry thoroughly. Soak element in clean engine oil and squeeze out excess oil.
Tap paper element lightly to remove excess dirt. Replace paper element if it appears heavily soiled.
SPARK PLUG:
Clean or replace the spark plug as needed to ensure proper operation. CAUTION A loose spark plug
can become very hot and may cause engine damage.
Remove the spark plug and inspect it.
Replace the spark plug if the insulator is cracked or chipped.
Clean the spark plug electrodes with a wire brush.

PRECAUTIONS
The trowel manufacturer has no direct control over machine application, operation, inspection,
lubrication, or maintenance. Therefore, it is your responsibility to use good safety practices in these
areas.
Do not use the trowel for any purpose other than its intended purposes or applications.
Know the capabilities and limitations of the trowel.
Walk around the trowel. Carefully inspect for evidence of physical damage, such as cracks,
bends, or deformation of plates and welds. Check for loose, broken or missing parts on the trowel,
including brackets, vibration isolators, nuts and bolts. Hardware should be replaced with original
equipment manufacturer’s (OEM) parts, and should be properly tightened to the manufacturer’s
recommendations.
Never check for hydraulic leaks with your hand. Hydraulic systems are under high pressure and leaks
in these systems can penetrate the skin which can result in serious injury or even death. Always use a
piece of cardboard or wood when looking for hydraulic leaks.
Exhaust from the engine contains poisonous carbon monoxide gas that is not easily detected as it is
colorless and odorless. Exposure to carbon monoxide can cause loss of consciousness and may lead
to death! Do not operate your trowel indoors or in an enclosed area unless adequate ventilation is
provided. Ensure that permissible carbon monoxide levels are monitored and not exceeded.
The mufer, exhaust pipes and other engine parts will become hot during operation and will remain hot
for a while after shut down. Do not touch until allowed to sufciently cool. Do not allow debris, rags,
paper, or leaves to accumulate around these areas.
MAINTENANCE AND TROUBLESHOOTING
9

PRECAUTIONS
Never operate a trowel with a damaged or worn electrical cord. When using an extension cord, be sure
to use one heavy enough to carry the current load. When trowel is used outdoors, use only extension
cords that are marked for outdoor use.
Batteries produce explosive gases. Keep open ame or sparks away. See the manufacturer’s
instructions when servicing the batteries, when using jumper cables, or when using a battery charger.
Use a ashlight to check battery electrolyte level. Always check with engine stopped. Battery electrolyte
is poisonous. It is strong enough to burn your skin, eat holes in clothing, and can cause blindness if
splashed into eyes. Always wear eye and face protection.
Be sure the trowel is properly lubricated. See that the fuel, lubricating oil, coolant and hydraulic
reservoirs are lled to the proper levels with the correct uids.
Never overll fuel tanks or uid reservoirs. 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.
Replace fuel cap securely after refuelling.
