SAE 30 40°F and higher (5°C and higher) is
good for all purpose use above 40°F. Use
below 40° will cause hard starting.
10W-30 0 to 100°F (-18 to 38°C) is better for
varying temperature conditions. This viscosity
improves cold weather starting, but may
increase oil consumption above 80°F (27°C).
*Check oil level frequently at higher
temperatures.
Synthetic 5W-30 -20 to 120°F (-30 to 40°C)
provides the best protection in all
temperatures, as well as improved starting
with less oil consumption.
5W-30 40°F and below (5°C and below) is
recommended for winter use and works best
in cold conditions.
Checking the Oil Level
1. Park the machine on a level surface,
disengage the blade control switch, stop
the engine, engage parking brake, and
remove the key.
2. Make sure the engine is stopped, level,
and is cool so the oil has had time to drain
into the sump.
3. To keep dirt, grass clippings, etc., out of
the engine, clean the area around the oil
fill cap/dipstick before removing it.
4. Pull and remove the oil fill cap/dipstick;
wipe oil off. Reinsert the dipstick and
push firmly into place

5. Remove the dipstick and check the oil
level. (Figure
The oil level should be up to, but not over,
the F mark on the dipstick.
6. If the level is low, add oil of the proper
type, up to the F mark on the dipstick.
Always check the level with the dipstick
before adding more oil.
Note:
To prevent extensive engine wear or
damage, always maintain the proper oil level
in the crankcase. Never operate the engine
with the oil level below the "L" mark or over
the "F" mark on the dipstick.
Changing the Oil and the Filter
Change the oil filter annually or every 100
hours of operation. Refill with service class
SF, 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
neutral position and engage parking
brake.
4. Stop the engine, remove the key, and wait
for all moving parts to stop before leaving
the operating position.
5. Clean the area around the drain plug and
on the machine frame. Place a pan
underneath machine directly below the
drain hole in the frame as shown in
Figure 24.
