CAUTION
1. Before starting trimming, check that all the safety devices are attached. The nylon cutting head is fixed securely, the Allen
wrench has been removed and the nylon cord is the appropriate length.
2. When using the trimmer, be sure to wear goggles, hearing protection and gloves.

Take care not to drag the head on the ground.

11. MAINTENANCE
11-1. Cleaning the air cleaner
A dirty air cleaner will choke the engine, therefore causing the engine
to stop.
Wash the air cleaner as required.
Replace the cleaner when it becomes dirty.
1. Detach the cleaner mounting screws and remove the cleaner cover.
2. Remove the element.
3. Follow the same procedure as in Fig.21.
Fig.21
11-2. Lubricating the gear housing with grease
The gear housing has a greasing port. Remove the greasing ports screw and feed grease into port. Grease the port after every 20 hours of
operation. Fig.22

Fig.23
11-3. Checking the gear housing mounting screws
Loose gear housing fixing screws are very dangerous even though they have covers to prevent them from coming off. Be sure to check them
before operating the trimmer. Tighten the screws securely with the Allen wrench provided with the trimmer.
11-4. Spark plug
The spark plugs have a standard electrode-to-electrode distance of 0.6 to 0.7mm Fig.23
The spark plug electrodes are dry and brown under optimum operating conditions. Clean as necessary.
Use spark plugs designated for the engine.
11-5. Fuel strainer cleaning
The fuel hose has a felt strainer at its end (in the fuel tank) to prevent foreign matter such as sand from entering the carburetor. Clean the strainer
as required because the pump cannot suck up fuel if the strainer is clogged, which would cause the engine to stop. Replace the felt strainer if it is
clogged or damaged.
CAUTION
The trimmer was designed to cut weeds, grass and similar soft vegetation.
Never use the trimmer for any other applications!
