CAUTION: Before doing any work on the Petrol Brushcutter, 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 cutter blade or nylon
cutting head.
– Before operation, always check for clogging of the cooling air passage and the cylinder ns.
Clean them if necessary.
– Perform the following work daily after use:
• Clean the Petrol Brushcutter externally and inspect for damage.
• Clean the air lter. When working under extremely dusty conditions, clean the lter the severall times a day.
• Check the blade or the nylon cutting head for damage and make sure it is rmly mounted.
• Check that there is sufcient 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 look button.
SERVICING INSTRUCTIONS
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,
conrm that the engine main unit and engine oil are sufciently cooled down. Otherwise, there may remain a risk of
scald.
Note: If the oil lled above the limit, it may be contaminated or may catch re with white smoke.
Interval of replacement: Initially, every 20 operating hours, and subsequently every 50 operating hours
Recommended oil: SAE10W-30 oil of API Classication SF Class or higher (4-stroke engine oil for automobile)
In replacement, perform the following procedure.
1) Conrm that the fuel tank cap is tightened securely.
2) Place large container (pan, etc.) under drain hole.

3) Remove drain bolt and then remove oil cap to drain out oil from drain hole.
At this time, be sure not to mislay drain bolt’s gasket, or to dirty any of the
removed components.
4) Once all the oil has been drained, combine gasket and drain bolt, and tightly
secure drain bolt, so that it will not loosen and cause leaks.
* Use cloth to fully wipe off any oil attached to bolt and equipment.
