Changing the Engine Oil
Service Interval: 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 for 5 minutes.
Note:
This warms the oil so that it drains better.
2. Park the machine so that the drain side is slightly
lower than the opposite side to ensure that the
oil drains completely.
