Maintenance

FUEL FILTER

When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage.

SPARK PLUG

Starting failure and mis-firing are often caused by a fouled spark plug. Periodically clean the spark plug and check that the spark gap is in the correct range. For a replacement plug, use the correct type specified by RedMax(See SPECIFI- CATIONS on the page 4).

REPLACEMENT PLUG IS A CHAMPION RCJ6Y OR THE EQUIVALENT, SUCH AS BOSCH WSR8E OR NGK BPMR7A.

IMPORTANT

Note that using any spark plugs other than those designated may result in the engine failing to operate properly or in the engine becoming overheated and damaged.

To install the spark plug, first turn the plug until it is finger tight, then tighten it a quarter turn more with a socket wrench.

MUFFLER

WARNING

Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, do not use the brushcutter and have it repaired immediately.

Note that failing to do so may result in the engine catching on fire.

SPARK ARRESTER

The muffler is equipped with a spark arrester to prevent red hot carbon from flying out of the exhaust outlet. Periodically inspect and clean as necessary with a wire brush. In the State of California it is required by law (Section 4442 of the California Public Resources Code) to equip a spark arrester when a gas powered tool is used in any forest covered, brush covered, or grass covered unimproved land.

GEAR CASE

The reduction gears are lubricated by multipurpose, lithium-based grease in the gear case. Supply new grease every 50 hours of use or more often depending on the job condition.
