After 50 operating hours, clean the
spark plug and re-adjust the electrode
gap to 0.7–0.8 mm. Only clean the spark
plug using a wire brush and wash it out
with a commercial cleaning agent.
l
Replace the spark plug at 100-hour
intervals or when it shows significant
wear or if the insulator is damaged.
Correct spark plug assembly:
Screw the spark plug into the cylinder
head by hand. Then continue with a spark
plug wrench. Turn wrench at 90° or at a
torque of 20…30 Nm.
Cleaning the cooling fan grille
After prolonged operation, the cooling
system may become clogged by dirt etc.
To avoid any overheating and damage to
the engine, regularly clean the cooling fan
grille (B/2).
Check before each operation!
Air cooling system
1) Clean the rotating strainer at 50-hour
intervals as a minimum (earlier in very
dusty and trashy conditions). To do this,
remove the recoil starter. See the illus-
tration below.
2) Clean the internal cooling fins and
surfaces at 100-hour intervals as a mini-
mum (earlier in very dusty and trashy
conditions).
For this purpose, contact your profes-
sional agria workshop.
