Cylinder Cooling Fins

Maintenance Interval

・

The cylinder cooling fins should be cleaned after every

25hours of operation, or once a week, whichever comes

first.

・

Air must flow freely around and through the cylinder cool-

ing fins to prevent engine overheating. Leaves, grass, dirt

and debris buildup on the fins will increase the operating

temperature of the engine, which can reduce engine per-

formance and shorten engine life.

Spark Plug

Maintenance Interval

・

The spark plug should be removed from the engine and

checked after each 25 hours of operation.

・

Replace the spark plug after every 100 hours of operation.

Spark Plug Maintenance

1. Twist the high tension lead boot on the spark plug back

and forth a couple of times to loosen the boot, then pull

the boot off of the spark plug.

2. Remove the spark plug.

3. Clean the electrodes with a stiff brush.

4. Adjust the electrode air gap to 0,6-0,7 mm.

5. Replace the spark plug if it is oil-fouled, damaged, or if the

electrodes are worn down.

6. Do not over tighten the spark plug when installing. The

tightening torque is 10,7-16,6 N·m.
