MAINTENANCE
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear safety goggles or safety glasses with side
shields during product operation. If operation is dusty,
also wear a dust mask.
WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in

GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
Stop the engine whenever you leave the operating position.
Disconnect the spark plug lead before unclogging the cut-
ting member guard or when making a repair, adjustment,
inspection, or the like.
Keep all nuts, bolts, and screws tight.
You can often make adjustments and repairs described here.
For other repairs, have the product serviced by an authorized
service dealer.
