Servicing the Air Cleaner
Foam Element: Clean after every 25 operating hours, or
yearly, whichever occurs first.
Paper Element: Replace after every 100 operating hours or
yearly, whichever occurs first.
Note: Service the air cleaner more frequently (every few
hours) if operating conditions are extremely dusty or
sandy.
Removing the Foam and Paper Elements
1. Disengage the PTO, set the parking brake, stop the
engine, and remove the ignition key.
2. Clean around the air cleaner to prevent dirt from
getting into the engine and causing damage. Pull up on
the air cleaner cover handle and rotate it toward the
engine (Fig. 20). Remove the air cleaner cover.
