NOTE!
Standard Idle rpm is 2800-3200 rpm
When the engine is idling the cutting attachment must under no circumstances rotate.
AIR FILTER (Fig. 3-2)
The air filter must be cleaned from dust and dirt in
order to avoid:
• Carburetor malfunctions.
• Starting problems.
• Engine power reduction.
• Unnecessary wear on the engine parts.
• Abnormal fuel consumption.
Clean the air filter daily or more often if working in
exceptionally dusty areas.
CLEANING THE AIR FILTER
• Remove the air filter cover and the filter (2).
• Rinse it in warm soap suds. Check that the filter is dry before reassembly. An air filter
that has been used for some time cannot be cleaned completely. Therefore, it must
regularly be replaced with a new one. A damaged filter must always be replaced.
FUEL FILTER
Drain all fuel from fuel tank and pull fuel filter line from tank. Pull filter element out of
holder assembly. Replace filter if it appears to be discolored or hardened from use. The
filter has a white, felt-like appearance when new.
SPARK PLUG (Fig. 3-3)
The spark plug condition is influenced by:
• An incorrect carburetor setting.
• Wrong fuel mixture (too much oil in the gasoline)
• A dirty air filter.
• Difficult running conditions (such as cold weather).
These factors cause deposits on the spark plug electrodes, which may result in malfunc-
tion and starting di culties. If the engine is low on power, di cult to start or runs poorly
at idling speed, always check the spark plug first. If the spark plug is dirty, clean it and
check the electrode gap. Readjust if necessary. The correct gap is 0.6 mm. The spark
plug should be replaced after about 100 operation hours or earlier if the electrodes are
badly eroded.
