low, add oil of the proper type up to the full mark.

Changing the Oil and the Filter
Service Interval: Every 100 hours—Change the engine
oil and filter.
Refill with service class SG, SH, SJ or higher oil as
specified in the "Viscosity Grades" table.
Change the oil and filter while the engine is still warm.
The oil will flow more freely and carry away more
impurities. Make sure the engine is level when filling,
checking, or changing the oil.
Change the oil and oil filter as follows:
1. Start the engine and let it run until warm. 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.
3. Disengage the blade control switch and move the
motion controls outward to the park position.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
5. Locate the oil drain hose on the left side of the
engine. The drain plug is attached to a drain hose
routed through a drain hole in the machine frame
(Figure 29). Clean the area around the oil drain plug
cap and the oil drain hose.
6. Place a pan underneath machine directly below the
oil drain hose as shown in Figure 29.

and one to loosen the plug), remove the oil drain
plug (Figure 29).
8. Remove the oil fill cap/dipstick (Figure 28).
9. Be sure to allow ample time for complete drainage.
10. Locate the oil filter on the right side of the engine.

with a clean cloth (Figure 30).
