Section 3. Scheduled Maintenance
3.1 General Maintenance
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before working on the generator set. Remove the
negative (–) lead first when disconnecting the battery. Reconnect the negative (–)
lead last when reconnecting the battery.
Disabling the generator set. Accidental starting can cause severe injury or death. Before working on the generator set or
equipment connected to the set, disable the generator set as follows: (1) Press the generator set off/reset button to shut down
the generator set. (2) Disconnect the power to the battery charger, if equipped. (3) Remove the battery cables, negative (–) lead
first. Reconnect the negative (–) lead last when reconnecting the battery. Follow these precautions to prevent the starting of the
generator set by the remote start/stop switch.
Hazardous voltage. Moving parts.
Will cause severe injury or death.
Operate the generator set only when all guards and electrical enclosures are in place.
Servicing the generator set when it is operating. Exposed moving parts will cause severe injury or death. Keep hands,
feet, hair, clothing, and test leads away from the belts and pulleys when the generator set is running. Replace guards, screens,
and covers before operating the generator set.
Grounding electrical equipment. Hazardous voltage will cause severe injury or death. Electrocution is possible whenever
electricity is present. Ensure you comply with all applicable codes and standards. Electrically ground the generator set, transfer
switch, and related equipment and electrical circuits. Turn off the main circuit breakers of all power sources before servicing the
equipment. Never contact electrical leads or appliances when standing in water or on wet ground because these conditions
increase the risk of electrocution.
Disconnecting the electrical load. Hazardous voltage will cause severe injury or death. Disconnect the generator set from
the load by turning off the line circuit breaker or by disconnecting the generator set output leads from the transfer switch and
heavily taping the ends of the leads. High voltage transferred to the load during testing may cause personal injury and equipment
damage. Do not use the safeguard circuit breaker in place of the line circuit breaker. The safeguard circuit breaker does not
disconnect the generator set from the load.
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling, storing, and using fuels.
The fuel system. Explosive fuel vapors can cause severe injury or death. Vaporized fuels are highly explosive. Use extreme
care when handling and storing fuels. Store fuels in a well-ventilated area away from spark-producing equipment and out of the
reach of children. Never add fuel to the tank while the engine is running because spilled fuel may ignite on contact with hot parts
or from sparks. Do not smoke or permit flames or sparks to occur near sources of spilled fuel or fuel vapors. Keep the fuel lines
and connections tight and in good condition. Do not replace flexible fuel lines with rigid lines. Use flexible sections to avoid fuel
line breakage caused by vibration. Do not operate the generator set in the presence of fuel leaks, fuel accumulation, or sparks.
Repair fuel systems before resuming generator set operation.
Draining the fuel system. Explosive fuel vapors can cause severe injury or death. Spilled fuel can cause an explosion.
Use a container to catch fuel when draining the fuel system. Wipe up spilled fuel after draining the system.
