SERVICING INSTRUCTIONS

CAUTION: Before doing any work on the equipment, 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 metal 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 equipment externally and inspect for damage.
• Clean the air filter. When working under extremely dusty conditions, clean the filter the several 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 throttle lever, and the lock button.
CLEANING OF AIR CLEANER
WARNING: Shut off the engine, keep away from open flames
and do not smoke.
Interval of Cleaning and Inspection: Daily (every 10 operating hours)
– Turn the choke lever (4) to the full close side, and keep the carburetor off
from dust or dirt.
Removing air cleaner cover
– Remove the screw (1), and remove the air cleaner cover (2).
Cleaning element
– Remove the element (3) and tap them to remove dirt.
– For heavy contamination:
Remove the sponge element, wash it in water diluted detergent and dry it
completely.
– After the element is dried, dip it into 2 stroke engine oil, then wring it out to
remove excess oil.
– Before attaching the sponge element, make sure that the oil is applied onto
the element evenly. Excess oil may lead to difficult start-up.
– Wipe out oil adhering around the air cleaner cover with cloth.
Attaching air cleaner cover
– After cleaning, return the sponge element. Return the air cleaner cover. And then fasten it with the screw.
NOTICE:
– If there is excessive dust or dirt adhering to the air cleaner, clean it everyday. Dirty elements reduce engine power and make starting
engine difficult.
– Remove oil on the elements. If operation continues with the elements remaining not cleared of oil, oil in the air cleaner may fall outside,
resulting in contamination of the environment.
– Do not put the elements on the ground or dirty place. Otherwise they pick up dirt or debris and it may damage the engine.
– Never use fuel for cleaning the elements. Fuel may damage them.
