Cleaning the Primary Filter
Blow compressed air from the inside to the outside of the
primary filter.
Important Do not exceed 100 psi and keep the hose at
least 2 inches from the filter. Replace air filters if they are
damaged or cannot be cleaned.
Servicing the Safety Filter
Do not clean the safety filter. Replace it after 600
operating hours.
Important Never attempt to clean the safety filter. If
the safety filter is dirty, then the primary filter is damaged
and you should replace both filters.
Installing the Filters
Important
To prevent engine damage, always operate
the engine with both air filters and cover installed.
1. If installing new filters, check each filter for shipping
damage. Do not use a damaged filter.
2. If the safety filter is being replaced, carefully slide it
into the filter body (Fig. 36).
3. Carefully slide the primary filter over the safety filter
(Fig. 36). Ensure that it is fully seated by pushing on
the outer rim of the filter while installing it.
Important 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 (Fig. 36).
Servicing the Engine 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.

Checking the Oil Level
Note: Check oil when engine is cold.
1. Disengage the power take off (PTO) and turn the
ignition key to off. Move levers to neutral locked
position and apply parking brake. Remove the key.
2. Clean around the oil dipstick (Fig. 37) so dirt cannot
fall into the filler hole and damage the engine.

3. Pull the oil dipstick and wipe the metal end clean
(Fig. 37).
4. Slide the oil dipstick fully into the filler tube. Pull the
dipstick out and look at the metal end (Fig. 37). 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.
