5. Continue holding down the ON/OFF switch on the drill
and at the same time press the TEST button on the
GFCI receptacle.
6. Verify that the drill turns off when the TEST button
was pressed.
7. If the drill motor continues to run after the TEST button
was pressed then it can be determined that the GFCI
receptacle is not working properly and should be
replaced.
8. Press the RESET button to restore power to the GFCI
receptacle.
PROTECTION DEVICES
NOTICE
Low oil pressure, high coolant temperature, high
engine speed and battery charge are considered major
protection parameters and will cause the engine to
shutdown.
1. This unit is equipped with protection devices. When
any of the major protection devices are activated, the
engine will automatically stop and the error code
message will be displayed on the DC welding current
meter (Figure 74).

GENERATOR SIDE
If the power transistor (PTR), insulated-gate bipolar
transistor (IGBT) on the welding side become abnormally
hot, a protective error code will be displayed on the DC
welding current meter. This condition will cause the welding
to stop, but will not shutdown the engine.
An error code of E10 will be displayed on the terminal A
side, while an error code of E20 will be displayed on the
terminal B side.
The cause of these two error codes (E10/E20) is due to
an overload condition on the welding side (duty cycle over
the limit) or insufficient cooling due to an open cabinet
door or blocked air intake. Take corrective action on these
conditions and welding will resume when the PTR (IGBT)
cools down.
FUSES
The engine wiring system has its own fuses (F2 and F5). If
either of these fuses are blown, check the wiring to determine
if an electrical short circuit exists. Correct the problem
before installing new fuses.
