SERVICING YOUR GENERATOR
SPARK PLUG SERVICE
In order to service the spark plug, you will need a spark plug wrench
(commercially available).
Required spark plug: BPR5ES (NGK)
To ensure proper engine operation, the spark plug must be properly gapped
and free of deposits.
An incorrect spark plug can cause engine damage.
If the engine is hot, allow it to cool before servicing the spark plug.
1. Disconnect the spark plug cap, and remove any dirt from around the spark
plug area.
2. Remove the spark plug with a spark plug wrench.
3. Inspect the spark plug. Replace it if the electrodes are worn or fouled, or if the
insulator is cracked or chipped. Clean the spark plug with a wire brush if it is
to be reused.
