Checking / replacing the spark plug
- Do not touch the spark plug or the spark plug
connector while the engine is running. High voltage!
- Risk of burning on the hot engine.
- Wear protective gloves.
Check the spark plug and the spark gap on a regular basis.
For this proceed as follows:
Allow the engine to cool down.
Pull the spark plug connector (49) from
the spark plug (48).
Remove the spark plug using the
supplied spark plug socket spanner (50).
The spark gap must be 0.7 to 0.8 mm.
Clean the spark plug when it is contaminated.
Install the spark plug in reverse order.
Do not overtighten the spark plug.
Replace the spark plug:
every 100 hours or once in a year (whichever case comes
-
first)
when the insulating body is damaged,
-
when the electrodes show excessive erosion,
-
when the electrodes show excessive dirt or oil.
-
Use the following spark plug type: F7RTC
Alternative spark plugs:
Bosch WR 7 DC; NGK VPR 6 ES; Champion RN 9 YC;
Oregon OLR 15 YC
Checking the ignition spark
1. Allow the engine to cool down.
2.
Pull the spark plug connector (49) from the spark plug
(48).
3.
Remove the spark plug using the supplied spark plug
socket spanner (50).
4. Firmly connect the spark plug connector.
5. Adjust the engine as described in "Cold start of the engine"
(section 1-4).
6. Use an insulated pair of tongs to press the spark plug
against the engine body (away from the spark plug hole).
7. Firmly pull the cranking rope on the cranking handle.
A spark between the electrodes is a sign of proper
functioning.

Open the oil filling plug (30).
Place a container with a capacity of at least 0.6 litres
below the oil drain plug.
Tilt the motor hoe to allow the oil to flow out.
Thoroughly clean the area around the oil outlet.
Screw the oil drain plug (31) in.
Fill new oil as described under " Preparing for startup".
Please refer to the "Engine Operating Instructions" for
