of the paper element. Clean it by gently tapping it on a
flat surface or replace it if needed.
5. Install the foam element, paper element, and air cleaner
cover.
Important: Do not operate the engine without the
air cleaner element because extreme engine wear
and damage will likely result.

Replacing the Spark Plugs

Service Interval: Every 800 hours
The recommended air gap is 0.76 mm (0.030 inch)
The correct spark plug to use is a Champion RC 14YC.
Note: The spark plug usually lasts a long time; however, the
plug should be removed and checked whenever the engine
malfunctions.
1. Clean the area around the spark plugs so foreign matter
cannot fall into the cylinder when the spark plug is
removed.
2. Pull the spark plug wires off of the spark plugs and
remove the plugs from the cylinder head.
3. Check the condition of the side electrode, center
electrode, and center electrode insulator to ensure that
there is no damage.
Important: Replace a cracked, fouled, dirty, or
otherwise malfunctioning spark plug. Do not sand
blast, scrape, or clean electrodes by using a wire
brush because grit may eventually release from the
plug, fall into the cylinder, and damage the engine.
4. Set the air gap between the center and side of the
electrodes at 0.76 mm (0.030 inch) (Figure 44).
5. Install the correctly gapped spark plug with gasket seal,
and tighten the plug to 23 N-m (200 in-lb). If a torque
wrench is not used, tighten the plug firmly.
