Servicing the Air Cleaner

Service the air cleaner foam pre-cleaner after every 50
operating hours and the air cleaner cartridge after every
100 operating hours (more frequently when operating
conditions are dusty or dirty).
1. Release the locking clips and remove the air cleaner
cover (Figure 46). Clean the cover thoroughly.

2. Remove the wing nut securing the elements to the
air cleaner body.
3. If the foam element is dirty, remove it from the paper
element (Figure 47). Clean it thoroughly, as follows:
A. Wash the foam element in a solution of liquid
soap and warm water. Squeeze it to remove dirt,
but do not twist it because the foam may tear.
B. Dry it by wrapping it in a clean rag. Squeeze the
rag and foam element dry.

4. When servicing the foam element, check the
condition of the paper element. Clean it by gently
tapping it on a flat surface or replace it if needed.
5. Install the foam element, paper element, and air
cleaner cover.
Important: Do not operate the engine without
the air cleaner element because extreme engine
wear and damage will likely result.
Changing the Engine Oil and
Filter
Change the oil and filter after the first 8 hours of
operation. Thereafter, change the oil every 50 hours and
the filter every 100 hours.
1. Remove the drain plug (Figure 48) and let oil flow
into a drain pan. When the oil stops, install the drain
plug.

of clean oil to the new filter gasket.

the filter adapter, then tighten 1/2 to 3/4 turn
further. Do not overtighten.
4. Add oil to the crankcase; refer to Checking the
Engine Oil.
5. Dispose of the used oil properly.
