WARNING
• An electric shock can result in serious injury or death.
• Always perform the GFCI test before using the
generator. If the GFCI system fails the test, the
machine must be repaired by an authorized service
center.
• If the GFCI fails to trip when the test button is pressed
(power "ON" light does not go off) or fails to reset
(power "ON" light does not go on) the device is
inoperative and should be replaced immediately.
• If the GFCI tests properly without any appliance
connected to it but trips each time an appliance is
connected to it, the appliance has a ground fault and
needs to be repaired or replaced. DO NOT USE THE
APPLIANCE IF THIS CONDITION OCCURS: A REAL
SHOCK HAZARD MAY EXIST.
• Due to the risk of power interruption, do not power life
support equipment from this machine.
• GFCI's do not protect against short circuits or
overloads.
• Unplug accessories and tools before attempting
service.
• Close the front service doors protecting the receptacles
when operating the machine.
• Do not test or reset the GFCI while at idle speed.
• If the LED blinks, stop using the GFCI receptacle and
have it replaced by an authorized service center.
• Long extension cords or cords with poor insulation may
allow enough leakage current to trip the GFCI.

OvERLOAD OPERATION:

In the event that the combined weld + auxiliary power load
exceeds the machine's capability, the welding circuit will continue
to drive as much power as possible without causing damage to
any components. Continued operation in an overload state will bog
and stall the engine. Overloading just the auxiliary power circuits
will cause the circuit breakers to trip.

AuXILIARY POWER RECEPTACLES:

Combined continuous output of all receptacles is limited to 10.0
kW for the Ranger 330MPX. The current rating of any plug used
with a receptacle must be at least equal to the rating of the
receptacle.
Output voltage is within ±5% at all loads up to rated capacity.
