Maintenance
WARNING
Unintentional sparking can result in fire or electric shock.
Unintentional start-up can result in entanglement, traumatic
amputation, or laceration.
Before performing adjustments or repairs:
• Disconnect the spark plug wire and keep it away from
the spark plug.
• Disconnect battery at negative terminal (only engines
with electric start).
• Use only correct tools.
• Do not tamper with governor spring, links, or other parts
to increase engine speed.
• Replacement parts must be of the same design and
