CAUTION: Before doing any work on the edger, 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 fins.
–
Clean them if necessary.
Perform the following work daily after use:
–
• Clean the edger 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 blade or 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.

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,
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, after 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)
In replacement, perform the following procedure.
1) Confirm that the fuel tank cap (1) is tightened securely.
2) Place large container (pan, etc.) under drain hole (3).

3) Remove drain bolt (5) and then remove oil cap (2) to drain out oil from drain
hole.
At this time, be sure not to mislay drain bolt’s gasket (4), 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.
