Cleaning the air cleaner
CAUTION:
• Always wear eye protection.
To clean the air cleaner, perform following steps:
1. Move up the combination switch (choke position) to prevent dirt or foreign
materials from falling into the carburetor.
2. Open two hooks with a flat screwdriver, and remove the cleaner cover.
3. Loosen the nut, and then remove the air cleaner.
NOTE:
• During cleaning, cover the opening with a clean cloth to prevent dirt or foreign
materials from falling into the carburetor.
• Replace the air cleaner immediately if it is damaged.
4. Tap it or clean it with a brush or air compressor to remove the dirt.
5. If the air cleaner is very dirty, replace it to a new one.
6. Return the air cleaner and cleaner cover by performing above steps in reverse.
Cleaning the fuel filter
The fuel filter of the suction head is used to filter the fuel required by the carburetor.
Perform visual inspection periodically.
1. Open the tank cap, use a wire hook and pull out the suction head through the
tank opening.
2. If the filter is hard or clogged up, replace it.
3. After checking, cleaning or replacing, fix the fuel filter onto the fuel pipe with the
hose clamp. Push the fuel filter in all the way to the bottom of the fuel tank.
NOTE:
• It is recommended to replace the fuel filter at least once every three month to
ensure an enough fuel supply to the carburetor. Otherwise an insufficient fuel
supply may cause the engine defects.
Checking the spark plug
CAUTION:
• Never touch the spark plug connector while the engine is running (danger of high
voltage electric shock).
The gap between the two electrodes of the spark plug should be 0.6 mm - 0.7 mm
(0.028" - 0.030"). If the gap is too wide or too narrow, adjust it. If the spark plug is
clogged or contaminated, clean it thoroughly or replace it.
0.6 mm - 0.7 mm
(0.028" - 0.030")
