General Service Tips
The air cleaners should be inspected periodically to maintain
maximum engine protection and maximum service life. These
inspections should include the following points.
1. Inspect the air transfer duct between the air cleaner and the
engine to be sure all clamps are tight, all flange joints are
tight, and there are no cracks in the ducting.
2. Air cleaner mounting bolts and clamps must be tight to hold
the air cleaner securely.
3. Check the dust cup to make sure it is sealing 360° around the
air cleaner body.
4. Automatic dust unloader valve (if so equipped) must be in
place, not inverted or damaged, and free from obstruction.
