Before cleaning, inspecting, or repairing the unit, make sure that the engine has stopped and is
cool.
•
Use protective gloves whenever inspecting, removing and installing the drill.
WARNING
•
Always be sure to stop the engine before
inspecting the brush cutter for problems or
performing maintenance.
•
Never alter the auger or take the engine
apart.
■
AIR FILTER
• The air filter, if clogged, will reduce the
engine performance. Monthly check and clean
the filter element in warm, soapy water as
required. Dry completely before installing. If the
element is broken or shrunk, replace with a new
one.

FUEL FILTER

check the fuel cap and the fuel filter for
blockage.

If the fuel filter is clogged, the engine speed
may be limited or speed fluctuations may occur.
•
If the engine is operated without a fuel filter,
dirt will accumulate in the carburetor and cause
damage.
