12. STORAGE INSTRUCTIONS
(OFF SEASON)
The following steps should be taken to prepare lawn
mower for storage.
1. Empty the tank after the last mowing of the season.
a) Empty the petrol tank with a suction pump.
CAUTION: Do not drain the petrol in closed
rooms, close proximity of open fire, etc. Do not smoke!
Petrol fumes can cause explosion or fire.
b) Start the engine and let it run until it has used up all
remaining petrol and stalls.
c) Remove the spark plug. Use an oilcan to fill approx.
20 ml oil into the combustion chamber. Operate the
starter to evenly distribute the oil in the combustion
chamber. Replace the spark plug.
2. Clean and grease the lawnmower carefully as
described above under “LUBRICATION
INSTRUCTIONS”.
3. Slightly grease the cutter to avoid corrosion.
4. Store the lawnmower in a dry, clean and frost-
protected place, out of reach of unauthorized persons.
CAUTION: The engine must have completely
cooled down before storing the lawnmower.
NOTE:
- When storing any type of power equipment in an
unventilated or material storage shed,
- Care should be taken to rust-proof the equipment.
Using a light oil or silicone, coat the equipment,
especially cables and all moving parts.

- If the starter rope becomes disconnected from rope
guide on handle, disconnect and ground the spark plug
wire. Depress the blade control handle and pull the
starter rope out from engine slowly. Slip the starter rope
into the rope guide bolt on handle.
