TRAILER (See Optional Features)

If the user adapts a non-Lincoln trailer, he must assume responsibility that the method of attachment and usage does not result in a safety hazard nor dam- age the welding equipment. Some of the factors to be considered are as follows:

1.Design capacity of trailer vs. weight of Lincoln equipment and likely additional attachments.

2.Proper support of, and attachment to, the base of the welding equipment so there will be no undue stress to the framework.

3.Proper placement of the equipment on the trailer to ensure stability side to side and front to back when being moved and when standing by itself while being operated or serviced.

4.Typical conditions of use, i.e., travel speed, rough- ness of surface on which the trailer will be operated; environmental conditions, likely maintenance.

5.Conformance with federal, state and local laws. (1)

(1)Consult your federal, state and local laws regarding specific requirements for use on public highways.

VEHICLE MOUNTING

Improperly mounted concentrated loads may cause unstable vehicle handling and tires or other compo- nents to fail.

•Only transport this equipment on serviceable vehi- cles which are rated and designed for such loads.

•Distribute, balance and secure loads so vehicle is stable under conditions of use.

•Do not exceed maximum rated loads for compo- nents such as suspension, axles and tires.

•Mount equipment base to metal bed or frame of vehicle.

•Follow vehicle manufacturer’s instruction.

POLARITY CONTROL AND CABLE SIZES

With the engine off, route the electrode and work cables through the strain relief bracket on the base and connect to the studs located below the fuel tank mounting rail. (See size recommendations below.) For positive polarity, connect the electrode cable to the terminal marked “+”. For Negative polarity, con- nect the electrode cable to the “-”stud. These con- nections should be checked periodically and tightened if necessary.

When welding at a considerable distance from the welder, be sure you use ample sized welding cables.

RECOMMENDED COPPER CABLE SIZES

Oil

This unit is supplied from the factory with the engine crankcase filled with a high quality SAE 10W/30 oil. This oil should be acceptable for most typical ambient temperatures. Consult the engine operation manual for specific engine manufacturer’s recommendations. Upon receipt of the welder, check the engine dipstick to be sure the oil is at the “full” mark. DO NOT overfill.

Fuel

Fill the fuel tank with the grade of fuel recommended in the Engine Operator’s manual. Make sure the fuel valves on the sediment bowl and the water separator are in the open positions.

Cooling System

The radiator has been filled at the factory with a 50-50 mixture of ethylene glycol antifreeze and water. Check the radiator level and add a 50-50 solution as needed (see engine manual or antifreeze container for alternate antifreeze recommendations).
