FUEL TANK CAP, TANK AND LINES
DANGER
Fuel is EXTREMELY flammable. Be very cautious and use care when mixing storing or
handling. Failure to follow this instruction may lead to serious personal injury.
Check for fuel leaks. Do not use the trimmer in the presence of a leak as it is a fire hazard. Loose or
damaged tank caps, or leaking tanks must be replaced immediately. Failure to follow this instruction
may lead to serious personal injury.
Use a clean cloth to remove loose dirt from around the fuel tank cap and empty the fuel tank. The
fuel tank cap contains a check valve. If the performance improves when the fuel tank cap is
loosened, the check valve may be faulty. Replace the fuel tank cap if required.
A clogged fuel filter will cause poor engine performance. Replace the fuel filter if required as it is a
non-serviceable part. Please contact your nearest service center for replacing this fuel filter.
