1. Carefully slide the foam element onto the paper air
cleaner element (Figure 32).

Servicing the Engine Oil
Oil Type:
Detergent oil (API service SF, SG, SH, or SJ)
Crankcase Capacity:
with filter, 51 ounces (1.5 l)
Viscosity:
See the table below.
Figure 35
Checking the Oil Level
Service Interval:
Before each use or daily—Check the
engine oil level.
1. Park the machine on a level surface and disengage
the blade control (PTO).
2. Move the motion control levers to the park position,
stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Remove the engine hood and engine duct to access
the engine components.
4. Clean around the oil dipstick (Figure 36) so that dirt
cannot fall into the fill hole and damage the engine.
5. Unscrew the oil dipstick and wipe the end clean

6. Insert the oil dipstick fully into the tube
without
screwing it in
. Pull the dipstick out, and look at the
end. If the oil level is low, slowly pour only enough
oil into the fill hole to raise the level to, but not over,
the Full mark on the dipstick.
Important:
Do not overfill the crankcase with
oil because the engine may be damaged.
7. Insert and screw the oil dipstick fully into the tube.
Changing and Draining the Oil
Service Interval:
After the first 8 hours—Change the
engine oil.
Every 100 hours—Change the engine
oil. (more often in dusty, dirty
conditions)
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 ensure that the oil
drains completely.
3. Disengage the blade control switch and set the
parking brake.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
CAUTION
Components will be hot if the machine has been
running. If you touch hot components you may
be burned.
Allow the machine to cool before performing
maintenance or touching components under
the hood.
