Servicing the Air Cleaner

Service Interval: Every 100 hours—Service the air
cleaner filter element (more often in
dusty, dirty conditions).
Every 200 hours—Replace the air
cleaner filter element (more often in

damage to the seal.

pressurized air or liquids, such as solvents,
gasoline, or kerosene. Replace the element if it
is damaged or cannot be cleaned thoroughly.

Servicing the Spark Plugs

Service Interval: Every 100 hours—Check the spark
plugs.
Ensure that the air gap between the center and side
electrodes is correct before installing each spark plug.
Use a spark plug wrench for removing and installing
the spark plugs and a gapping tool or feeler gauge to
check and adjust the air gap. Install new spark plugs if
necessary.
Type: NGK BPR4ES or equivalent
Air Gap: 0.030 inch (0.76 mm)
Removing the Spark Plugs
1. Disengage the blade control (PTO).
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Open the hood.
4. Remove the shield over the spark plugs.
