Changing the Oil and Filter

1. Start the engine and let it run five minutes. This warms
the oil so it drains better.
2. Park the traction unit so that the drain side is slightly
lower than the opposite side to ensure that the oil drains
completely.
3. Place one end of a hose on the drain valve and the other
end in a pan (Figure 21).
4. Open the drain valve by turning it counterclockwise,
pulling out as you turn it (Figure 21).

valve and remove the hose.
Note: Dispose of the used oil at a certified recycling center.
6. Remove the old filter and wipe the filter adapter
(Figure 22) gasket surface.

material, then pour off the excess oil.
9. Apply a thin coat of new oil to the rubber gasket on the
replacement filter (Figure 22).

80% of the specified amount of oil in through the valve
cover.

Operation (page 9).
