Undercarriages

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

1.Design capacity of undercarriage vs. weight of Lincoln equipment and likely additional attach- ments.

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 under- carriage 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 undercarriage will be operated; environmental conditions, likely mainte- nance.

5.Conformance with federal, state and local laws.Consult applicable federal, state and local laws regarding specific requirements for use on public highways.

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 “Positive (+)”. For Negative polarity, connect the electrode cable to the “Negative (-)”stud. These connections should be checked peri- odically and tightened if necessary.

When welding at a considerable distance from the

PRE-OPERATION SERVICE

READ the engine operating and maintenance instruc-

tions supplied with this machine.

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. Note: A optional Oil Drain Kit is available for this engine. (Order K1604-1)

NOTE: This unit is equipped with an Engine

Protection Package, an internal kill switch will shut down the engine if the oil pressure drops below a minimum operating specification, or if the oil temperature reaches an excessive level.

Fuel

Fill the fuel tank with the grade of fuel recommended in the Engine Operator’s manual. Make sure the fuel valve on the sediment bowl is in the open position.
