Changing/Draining Oil
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 drain side is slightly
lower than the opposite side to assure the oil drains
completely. Then disengage the power take off (PTO),
set the parking brake, and turn the ignition key to off.
Remove the ignition key.
3. Open the hood.
4. Slide a piece of hose over oil drain to direct oil.
5. Place a pan below the oil drain. Open the drain by
turning counterclockwise, 1/8 turn and pull out
(Fig. 23).
6. When oil has drained completely, close the drain by
pushing in and turning clockwise, 1/8 turn.
Note: Dispose of the used oil at a certified recycling
center.
