WARNING
Welding Hazard
• ALWAYS turn off the battery switch (if
equipped) or disconnect the negative
battery cable and the leads to the
alternator when welding on the equipment.
• Connect the weld clamp to the component
to be welded and as close as possible to
the welding point.
• NEVER connect the weld clamp to the
engine or in a manner which would allow
current to pass through a mounting
bracket.
• When welding is completed, reconnect the
leads to the alternator prior to
reconnecting the batteries.
Exhaust Hazard
ALWAYS ensure that all
connections are tightened to
specifications after repair is
made to the exhaust system.
All internal combustion

operation and special precautions are
required to avoid carbon monoxide
poisoning.
Shock Hazard
ALWAYS turn off the battery
switch (if equipped) or disconnect
the negative battery cable before
servicing the equipment.
ALWAYS keep the electrical connectors
and terminals clean. Check the electrical
harnesses for cracks, abrasions, and
damaged or corroded connectors.
NEVER use undersized wiring for the
electrical system.

of inspection, or any part whose measured
value does not satisfy the standard or limit,
must be replaced.
Modifications may impair the engine’s
safety and performance characteristics and
