Air cleaner systems used on these engines will be
either the standard size or PRO Series increased
capacity (slightly taller) design. Each system
uses a replaceable, high-density paper air cleaner
element. Some are also equipped with an oiled-foam
precleaner, which surrounds the paper element. See
Figures 4-1 and 4-2.
Check the air cleaner daily or before starting the
engine. Check for and correct any buildup of dirt and
debris, along with loose or damaged components.
NOTE: Operating the engine with loose or
damaged air cleaner components could
allow unfiltered air into the engine causing
premature wear and failure.
If so equipped, wash and reoil the precleaner
annually or every 25 hours of operation (more often
under extremely dusty or dirty conditions). Replace
the precleaner annually or every 100 hours.
To service the precleaner, see Figures 4-1 and 4-2, and
perform the following steps:
1. Open the door on the blower housing to access
the air cleaner element and precleaner. (On Pro
models the door can be removed).
2. Unhook the latch and remove the precleaner from
the air cleaner element, or remove as an assembly
for servicing. Make sure the base and the sealing
area is clean before reassembly is performed.
3. Wash the precleaner in warm water with
detergent. Rinse the precleaner thoroughly until
all traces of detergent are eliminated. Squeeze out
excess water (do not wring). Allow the precleaner
to air dry.
4. Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
5. Reinstall the precleaner over the paper air cleaner
element. Secure the element with the latch.
6. Close and latch the door.
