Installing the Foam and Paper Elements
Important To prevent engine damage, always operate
the engine with the complete foam and paper air cleaner
assembly installed.
1. Carefully slide the foam element onto the paper air
cleaner element (Fig. 19).
2. Place the air cleaner assembly onto the air cleaner base
(Fig. 19).
3. Install the air cleaner cover and secure it with the cover
nut (Fig. 19).

Spark Plug

Check the spark plug(s) after every 200 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(s) and a gapping tool/feeler gauge to check and adjust
the air gap. Install a new spark plug(s) if necessary.
Type: Champion RC12YC (or equivalent)
Air Gap: 0.030 inch (0.76 mm)
Removing the Spark Plug
1. Disengage the PTO and move the control levers to the
neutral locked position and apply the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Pull the wire(s) off of the spark plug(s) (Fig. 22). Clean
around the spark plug(s) to prevent dirt from falling into
the engine and potentially causing damage.
4. Remove the spark plug(s) and metal washer.
