GND/PE		gears insulate the welding generator from the
		gears insulate the welding generator from the
		vehicle frame. Always connect a ground wire
		from the generator equipment grounding termi-
		nal to bare metal on the vehicle frame as shown.

! Do not weld on base. Welding on base can cause fuel tank fire or explosion. Bolt unit down using holes provided in base.

! Always securely fasten weld- ing generator onto transport vehicle or trailer and comply with all DOT and other applica- ble codes.

! Do not mount unit by support- ing the base only at the four mounting holes. Use cross- supports to adequately sup- port unit and prevent damage to base.

! Always ground generator frame to vehicle frame to pre- vent electric shock and static electricity hazards.

! If unit does not have GFCI re- ceptacles, use GFCI-protected extension cord.

NOTICE − Do not install unit where air flow is restricted or engine may over- heat.

Mounting:

1 Cross-Supports

Mount unit on flat surface or use cross-supports to support base.

Grounding:

2Equipment Grounding Terminal (On Front Panel)

3Grounding Cable (Not Supplied)

4Metal Vehicle Frame

Connect cable from equipment ground terminal to metal vehicle frame. Use #10 AWG or larger insu- lated copper wire.
