OIL SERVICE

Refer to the Maintenance Schedule at the end of this section and ensure that the recommen-
dations are followed. More frequent service is required when operating in adverse conditions.
- Check the oil level every 5 hours or daily before starting the engine and ensure that
the correct oil level is maintained. Refer to-'Before Starting the Engine: Oil
Recommendations' for oil checking procedure and filling instructions.
- Change the engine oil after the first 5 hours of operation and thereafter at the end of
every grass cutting season. In circumstances where the engine is being operated for
long periods under heavy load or high ambient temperatures, the oil should be changed
at 25 hour intervals.
- Change the oil while the engine is warm. Refill with fresh clean oil of the recom-
mended SAE viscosity grade. Refer to -'Before Starting the Engine:Oil
Recommendations'.
WARNING - PREVENT ACCIDENTS: Drain fuel from the tank by running the engine
until the fuel tank is empty before attempting to tip the mower for oil draining
purposes.
- Remove the spark plug lead and allow the engine to
cool. Slacken the lower handlebar securing knobs and
move the handlebar assembly forwards. Tip the mower
backwards until the handlebar assembly is supported on
the ground, as shown. Remove the oil filler dipstick and
drain the oil into a suitable container.
