Maintenance

CAUTION: Before doing any work on the machine always switch off the motor
and pull the plug caps off the spark plugs (see "Checking the spark
plugs" on page 22).
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.
- Before operation, always check for clogging of the cooling air passage and the
cylinder fins.
Clean them if necessary.
- Perform the following maintenance daily after use:
• Clean the brush cutter externally and inspect for damage.
• Clean the air filter. When working under extremely dusty conditions, clean the
filter and blow out the cooling air passage and cylinder fins several times a day.
• Check the blade for damage and dullness 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 before further use of the tool.
- Check for proper functioning of the stop switch, the lock-off lever, the throttle lever,
and the lock button.
Cleaning of air cleaner
- Raise the lock lever (1) of the air cleaner cover and release the lock.
- Hold the right and left sides of the air cleaner cover, press it to the inside and then
remove it.
- Push the choke lever (2) up (arrow), to prevent dirt particles from entering the
carburetor.
- Remove the sponge element (3).
Wash it with lukewarm water and then dry it thoroughly.
- After cleaning, put back the sponge element and install the air cleaner cover (4)
and tighten the screw to secure.
NOTE: If there is excessive dust or dirt adhering to the air cleaner, clean it
every day. A clogged air cleaner may make it difficult or impossible to
start or run the engine at proper rotational speeds.
