WELDER / GENERATOR

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 normal 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 RECEPTACLE TESTING AND RESET- TING PROCEDURE

The GFCI receptacle should be properly tested at least once every month or whenever it is tripped. To proper- ly test and reset the GFCI receptacle:

•If the receptacle 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 recep- tacle. This will assure normal GFCI operation.

•Plug a night-light (with an "ON/OFF" switch) or other product (such as a lamp) into the GFCI receptacle and turn the product "ON".

•Push the "Test" button located on the GFCI recepta- cle. 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 prop- erly or has been incorrectly installed (miswired). If your GFCI is not working properly, contact a qualified, certi- fied electrician who can assess the situation, rewire the GFCI if necessary or replace the device.
