OIL CHANGE
It is recommended to ask authorized service for oil change.
Note: I The first oil change should be carried out after 5 operating hours, when operating
under heavy load another change should be done after 25 operating hours.
Drain the engine oil when the engine is warm. Warm oil drains quickly and complete.
Attention: Do not drain oil when the engine is running!
When you drain the oil from the top oil fill tube, the fuel tank must be empty or fuel
can leak out and result in a fire or explosion.
1. Place a suitable container next to the engine to catch the used oil.
2. Remove the oil filler cap/dipstick (fig. 22A).
3. Remove the drain bolt (fig. 23A) - if equipped - and allow the used oil to drain completely
into the container.
4. For engine without drain plug, we recommend to use oil extractor pump, or drain the oil
into the container by slightly tilting the engine toward the oil filler cap/dipstick (fig. 24).
Before tilting the machine, remove fuel from tank. Keep the spark plug end of the engine
up.
5. Reinstall the drain bolt. With the engine in a level position, fill to the upper limit mark on
cap/dipstick.
