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 into the paper air
cleaner element (Fig. 30).
2. Place the air cleaner assembly onto the air cleaner base
and install wing nut (Fig. 30).
3. Install the air cleaner cover and latch (Fig. 30).
Servicing the Engine Oil
Change oil:
After the first 8 operating hours.
After every 100 operating hours.
Note: Change oil more frequently when operating
conditions are extremely dusty or sandy.
Oil Type: Detergent oil (API service SG or SH)
Crankcase Capacity: without filter change, 51 oz. (1.5 l)
Crankcase Capacity: with filter change, 57 oz. (1.7 l)
Viscosity: See table below
USE THESE SAE VISCOSITY OILS
Checking the Engine Oil Level
1. Park the machine on a level surface.
2. Clean around the oil dipstick (Fig. 33) so dirt cannot
fall into the filler hole and damage the engine.
3. Unscrew the oil dipstick and wipe the end clean
(Fig. 33).
4. Slide the oil dipstick fully into the filler tube, do not
thread onto tube (Fig. 33). Pull the dipstick out and
look at the end. 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 Engine 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. Then disengage the power take off (PTO),
set the parking brake, and turn the ignition key to off.
Remove the key.
3. Place a pan below the oil drain. Use either a flat screw
driver, 3/8 inch or 10 mm wrench to open valve
(Fig. 34).
4. Rotate valve end clockwise to close valve. Rotate
valve end counterclockwise to open valve (Fig. 34).
5. When oil has drained completely, close the drain valve
(Fig. 34).
Note: Dispose of the used oil at a recycling center.
