• If the primary filter is dirty, bent, or damaged,
replace it.

Servicing the Safety Filter
Service Interval: Every 600 hours
Important: Never attempt to clean the safety filter.
If the safety filter is dirty, then the primary filter is
damaged. 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 (Figure 31).
3. Carefully slide the primary filter over the safety filter
(Figure 31).
Note: Ensure that the primary filter is fully seated
by pushing on its outer rim 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 upward and secure the latches (Figure 31).

Servicing the Engine Oil

operating conditions are extremely dusty or sandy.

Checking the Engine Oil Level
Service Interval: Before each use or daily
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 33) so that dirt
cannot fall into the filler hole and damage the engine.
1. Oil dipstick
5. Unscrew the oil dipstick and wipe the end clean
(Figure 33).
6. Slide the oil dipstick fully into the filler tube, but do
not thread onto tube (Figure 33).
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.
Important: Do not overfill the crankcase with
oil and run the engine; engine damage can
result.
