Cleaning the Foam Air Cleaner
Element
1. Wash the foam element in liquid soap and
warm water. When the element is clean, rinse
it thoroughly.
2. Dry the element by squeezing it in a clean
cloth.
Important:
Replace the foam element
if it is torn or worn.
Servicing the Paper Air Cleaner
Element
1. Do not clean the paper filter. Replace it after
200 operating hours (Figure 32).
2. Inspect the element for tears, an oily film, or
damage to the rubber seal.
3. Replace the paper element if it is damaged.
Installing the Foam and Paper
Elements
Important:
To prevent engine damage,
always operate the engine with the complete
foam and paper air cleaner assembly installed.
1. Carefully slide the foam element onto the
paper air cleaner element (Figure 32).
2. Place the air cleaner assembly onto the air
cleaner base and secure it with the 2 wing nuts
(Figure 32).
3. Place the air cleaner cover into position and
tighten the cover knob (Figure 32).
Servicing the Engine Oil
Service Interval/Specication
Change the engine oil as follows:
•
After the first 8 operating hours
•
After every 100 operating hours
Note:
Change the oil more frequently when
the operating conditions are extremely dusty
or sandy.
Oil Type: Detergent oil (API service SF, SG,
SH, or SJ)
Crankcase Capacity: 58 ounces (1.7 liter) with
the filter removed; 51 ounces (1.5 liter) without
the filter removed
Viscosity: Refer to the table below
Figure 33
Checking the Engine Oil Level
1. Park the machine on a level surface.
2. Disengage the PTO, turn the ignition key to
off, and remove the key.
3. Wait for all moving parts to stop before leaving
the operating position and then chock or block
tires.
4. Clean around the oil dipstick (Figure 34) so
that dirt cannot fall into the filler hole and
damage the engine.

1. Oil dipstick
2. Filler tube
5. Unscrew the oil dipstick and wipe the end
clean (Figure 34).
6. Slide the oil dipstick fully into the filler tube,
but do not thread onto tube (Figure 34).
7. Pull the dipstick out and look at the metal end.
If the oil level is low, slowly pour only enough
oil into the filler tube to raise the level to the
Full mark.
