MAINTENANCE
STOrAGE: Store in clean, dry protected areas.
CLEANING: Blow out the generator and controls peri-
odically with low pressure air. Do this at least once a
week in particularly dirty areas.
BrUSH rEMOVAL AND rEPLACEMENT: It's nor-
mal for the brushes and slip rings to wear and darken
slightly. Inspect the brushes when a generator over-
haul is necessary.
CAUTION
• Do not attempt to polish slip rings while the
engine is running.
WArNING
• Service and repair should only be performed by
Lincoln Electric Factory Trained Personnel.
Unauthorized repairs performed on this equip-
ment may result in danger to the technician and
machine operator and will invalidate your factory
warranty. For your safety and to avoid Electrical
Shock, please observe all safety notes and pre-
cautions.
GFCI TESTING AND RESETTING PROCEDURE
The GFCI should be properly tested at least once every month or
whenever it is tripped. To properly test and reset the GFCI:
• If the GFCI has tripped, first carefully remove any load and
check it for damage.
• If the equipment has been shut down, it must be restarted.
• The equipment needs to be operating at high idle speed and
any necessary adjustments made on the control panel so
that the equipment is providing at least 80 volts to the
receptacle input terminals.
• The circuit breaker for this receptacle must not be tripped.
Reset if necessary.
• Push the "Reset" button located on the GFCI. This will
assure normal GFCI operation.
• Plug a night-light (with an "ON/OFF" switch) or other
product (such as a lamp) into the Duplex receptacle and turn
the product "ON".
• Push the "Test" button located on the GFCI. The night-light
or other product should go "OFF".
• Push the "Reset" button, again. The light or other product
should go "ON" again.
If the light or other product remains "ON" when the "Test"
button is pushed, the GFCI is not working properly or has been
incorrectly installed (miswired). If your GFCI is not working
properly, contact a qualified, certified electrician who can assess
the situation, rewire the GFCI if necessary or replace the device.
For GFCI Models that have the appearance as shown in Figure
D.2, please use the following information and troubleshooting
guide listed below. For all other GFCI models, please use the
FIGUrE D.2
GFCI testing and resetting procedure listed previously.
• The GFCI automatically monitors ground fault circuit inter-
rupting functionality every (3) hours or less, and it also
automatically tests within (5) seconds of power to the
device.
• If the GFCI device can no longer provide GFCI protection it
will deny power and provide a visual indication that it no
longer can provide protection.
TROUBLESHOOTING GUIDELINES:
• If the line conductor is incorrectly wired to the load terminal,
power to the receptacle will be denied. This includes initial
installation and any subsequent reinstallations.
• Visual indicators: Green LED on represents power at the
face of the receptacle; solid Red LED on indicates a trip
condition and load is off. A flashing red LED indicates that
the GFCI is no longer functioning and needs replaced.
• Reverse Wire Safety Feature: The GFCI will not have power
at both the face and downstream if the line and load are
reverse wired. Additionally, the unit will not be able to reset
under a reversed wiring condition. If the line conductor is
incorrectly wired to the load terminal, power to the
receptacle will be denied. This includes initial installation
and any subsequent reinstallations.
• (GFCI no longer functioning): A rapid flashing red LED will
indicate that the unit can no longer provide ground fault
protection. This indication will occur regardless of the
specific test mode that is being conducted, automatic or
manual.
• If your GFCI is no longer working properly, contact a
qualified, certified electrician who can assess the situation
and rewire the GFCI if necessary or replace the device.
