7 STORAGE
The clearing saw should be stored in a dry place. Refer also
to section 2.4. When the clearing saw is to be stored for
periods longer than 4 months, carry out the following
procedures:
1. After draining out the petrol, start the engine and allow it
to run until all the remaining petrol is used up.
WARNING! The stop control should always be in
the stop position when the engine is turned round
with the spark plug lead or spark plug removed.
2. Remove the spark plug, (21) in Fig. 3, and apply 4-5
drops of oil in the spark plug hole. Place the stop control
in the stop position, see Fig. 14. (otherwise the ignition
coil will be overloaded). Pull the handle for the recoil
starter a few times so that the oil is distributed in the
cylinder and crankcase, and then refit the spark plug.
3. Clean the complete clearing saw and replace it in its
original pack.
