2. If the safety filter is being replaced, carefully
slide it into the filter body (Figure 27).
3. Carefully slide the primary filter over the safety
filter (Figure 27). Ensure that it is fully seated
by pushing on the outer rim of the filter while
installing it.
Note:
Do not press on the soft inside area
of the filter.
4. Install the air cleaner cover with the side
indicated as
UP
facing up and secure the
latches (Figure 27).
Servicing the Engine Oil
Change the engine oil as follows:
•
After the first 8 operating hours.
•
After every 100 operating hours.
Oil Type:
Detergent oil (API service SF, SG, SH
or SJ)
Crankcase Capacity:
with a filter change, 57
ounces (1.7 l); without a filter change, 47 ounces
(1.4 l)
Viscosity:
See the table below.
Figure 28
Checking the Engine Oil Level
Note:
Check the oil when the engine is cold.
1. Disengage the PTO, move the motion control
levers to the neutral locked position and set
the parking brake.
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Clean around the oil dipstick (Figure 29) so
dirt cannot fall into engine.

4. Pull the oil dipstick and wipe the metal end
clean (Figure 29).
5. Slide the oil dipstick fully into the engine. Pull
the dipstick out and look at the metal end
(Figure 29). If oil level is low, slowly pour only
enough oil into the filler tube to raise the level
to the full mark.
Important:
Do not overfill the crankcase
with oil because the engine may be
damaged. Do not run engine with oil
below the low mark because the engine
may be damaged.
Changing the 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.
3. Disengage the PTO 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.
5. Slide the drain hose over the oil drain valve.
6. Place a pan below the drain hose. Rotate oil
drain valve to allow oil to drain (Figure 30).
