Servicing the Engine Air
Cleaner
Inspect the paper element every 100 hours of operation and
replace it every 200 hours or when it becomes dirty or
damaged. Do not wash the paper element or do not clean it
with compressed air as damage will occur.
1. Park the machine on a level surface and turn the engine
off.
2. Pivot the seat upward.
3. Remove the knobs and air cleaner cover (Fig. 15).
4. Remove the filter and cover plate. Inspect the filter for
cleanliness, ruptures, holes, and tears. Replace a
damaged filter element.
Important With the air cleaner disassembled, check the
air cleaner components for damage. Replace them if
necessary. Make sure that the rubber breather tube in the
base plate is securely in place or severe engine damage may
occur.
