Inspecting the
spark plug
CAUTION!
NEVER touch the spark plug or spark plug cap while the
engine is running (high voltage)!
Never do maintenance work with the engine running!
A hot engine can cause severe burns. Wear protective
gloves!
The spark plug must be replaced if the insulator is damaged or
if the electrodes are severely eroded or dirty or oily.
- Pull the spark plug cap (
B/6) off the plug. Remove the spark
plug with a spark plug wrench (19 mm size).
Note:
Replace only with NGK BPMR8Y spark plugs!
Electrode gap
The electrode gap must be 0.6 - 0.7 mm.
Replacing the
spark plug
- Insert the wrench (C/7) between the housing and the cylinder,
only as shown in the illustration.
CAUTION!
Do not insert the wrench into the spark plug hole. Make
contact only with the cylinder (otherwise you may damage
the engine).
- Firmly connect the spark plug cap to the spark plug (removed
from the engine) and hold it against the wrench using insu-
lated pliers (away from the spark plug hole!).
- Move the combination switch (
I/O) to the “I” position.
- Pull the starter cable hard.
A spark should be visible at the electrode gap.
