Changing the Engine Oil
Service Interval: After the first 8 hours
Every 100 hours (more often in dirty or dusty
conditions)
Note: Dispose of the used oil at a recycling center.
1. Start the engine and let it run five minutes. This warms
the oil so it drains better.
2. Park the machine so that the rear is slightly lower than
the front to ensure the oil drains completely.
3. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position (Figure 49).

into the filler tube and slowly add the additional oil to
bring it to the Full mark (Figure 50).
