Engine Manual for details.
Spark Plug Adjustments and Replacement
For all Engine related maintenance and troubleshooting refer to the Engine Manual.
CAUTION
DO NOT work around the engine while hot.

When installing the Spark Plug,
ensure the threads are aligned with
the threads in the engine so as not to
"cross-thread" the plug.
Electrical System
A fuse protects the battery charging circuit. The fuse and the battery are the only user serviceable
parts of the electrical system, a short circuit or a battery connected in reverse polarity will blow the
fuse. Refer to the Engine Manual for the location and type of fuse. The fuse on the Engine is located
between the starter solenoid and the engine, and is rated at 30 amps.
CAUTION
If the fuse blows, determine the cause of the problem before resuming operations.
