Servicing the Air Cleaner
Clean the paper element after every 25 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 Paper Element
1. Disengage the PTO, shift into neutral, set the parking
brake, stop the engine, and remove the ignition key.
2. Open the hood.
3. Clean around the air cleaner to prevent dirt from getting
into the engine and causing damage. Unscrew the knob
and remove the air cleaner cover (Fig. 20).

Cleaning the Paper Element
1. Lightly tap the element on a flat surface to remove dust
and dirt (Fig. 22).
2. Inspect the element for tears, an oily film, and damage
to the rubber seal.

Never clean the paper element with
pressurized air or liquids, such as solvent, gas, or kerosene.
Replace the paper element if it is damaged or cannot be
cleaned thoroughly.

Installing the Paper Element
Important
To prevent engine damage, always operate
the engine with the complete air cleaner assembly installed.
1. Slide the paper element onto the long rod. Screw the
rubber nut finger-tight against the air cleaner (Fig. 21).
Note: Make sure that the rubber seal is flat against the air
cleaner base.
2. Install the air cleaner cover and knob (Fig. 20). Tighten
the knob snugly.
3. Close the hood.
Servicing the Spark Plug
Install a new spark plug after every 100 operating hours.
Check the spark plug after every 25 operating hours. Make
sure that the air gap between the center and side electrodes
is correct before installing the spark plug. Use a spark plug
wrench for removing and installing the spark plug and a
gapping tool/feeler gauge to check and adjust the air gap.
Type: Champion RJ-19LM (or equivalent)
Air Gap: 0.030 in. (0.762 mm)
