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

! 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 overheat.

.See Section 4-2for lifting eye rating.

.See Section 5-2for mounting information.

Grounding:

2Grounding Cable (Not Supplied)

3Metal Vehicle Frame

.Electrically bond generator

frame to vehicle frame by met- al-to-metal contact.

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

! Bed liners, shipping skids, and some running gears insu- late the welding generator from the vehicle frame. Al- ways connect a ground wire from the generator equipment grounding terminal to bare metal on the vehicle frame as shown.
