SERVICING INSTRUCTIONS

CAUTION: Before doing any work on the String Trimmer, always stop the engine and pull the plug cap off the spark plug (see "checking the
spark plug").
Always wear protective gloves!
To ensure a long service life and to avoid any damage to the equipment, the following servicing operations should be performed at regular
intervals.
Daily checkup and maintenance
– Before operation, check the machine for loose screws or missing parts. Pay particular attention to the tightness of the nylon cutting head.
– Before operation, always check for clogging of the cooling air passage and the cylinder fins.
Clean them if necessary.
– Perform the following work daily after use:
• Clean the String Trimmer externally and inspect for damage.
• Clean the air filter. When working under extremely dusty conditions, clean the filter the severall times a day.
• Check the nylon cutting head for damage and make sure it is firmly mounted.
• Check that there is sufficient difference between idling and engagement speed to ensure that the cutting tool is at a standstill while the
engine is idling (if necessary reduce idling speed).
If under idling conditions the tool should still continue to run, consult your nearest Authorized Service Agent.
– Check the functioning of the I-O switch, the lock-off lever, the control lever, and the Lock button.
REPLACEMENT OF ENGINE OIL
Deteriorated engine oil will shorten the life of the sliding and rotating parts to a great extent. Be sure to check the period and quantity of
replacement.
ATTENTION: In general, the engine main unit and engine oil still remain hot just after the engine is stopped. In replacement of oil,
confirm that the engine main unit and engine oil are sufficiently cooled down. Otherwise, there may remain a risk of
scald.
Note: If the oil filled above the limit, it may be contaminated or may catch fire with white smoke.
Interval of replacement: Initially, every 20 operating hours, and subsequently every 50 operating hours
Recommended oil: SAE10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile)
