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.
Installing the Filters
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. 19).
3. Carefully slide the primary filter over the safety
filter (Fig. 19). 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. 19).

dusty or sandy.

Changing the Oil
1. Start the engine and let it run for five minutes.
This warms the oil so it drains better.
2. Park the traction unit so that the drain side is
slightly lower than the opposite side to ensure
that the oil drains completely.
