D. Switch Guard Installation (Figure 3-5)

IMPORTANT: Switch guard installation is only neces- sary on welding generators without this bracket installed from the factory.

1.Locate the supplied switch guard (angle bracket), and using the guard as a template, mark the two mounting hole locations onto lower front portion of the welding generator base as shown in Figure 3-5.

CAUTION: METAL FILINGS AND/OR TOOL CONTACT WITH INTERNAL COM- PONENTS can damage unit.

Cover internal components.

Clean unit, and remove internal covering material before resuming operation.

2.Drill 9/32 in. (7 mm) diameter hole at each marked location.

3.Install and secure the switch guard with the two supplied 5/16-18 x 3/4 in. self-forming screws.

E.Final Procedure

1.Reinstall weld output terminal bracket onto left front upright.

IMPORTANT: To ease reinstalling of the weld output terminal bracket, position cables 19 and 30 below the bottom edge of the bracket so that the cables are routed along the left side of the stator barrel. Also, check the bimetal jumper bar connection at the rear of the weld output terminal after reinstalling the bracket; tighten the bimetal jumper bar securing hardware if necessary.

2.Affix supplied ELECTRODE label over NEGA- TIVE designation for weld output terminal.

3.Affix supplied WORK label over POSITIVE des- ignation for weld output terminal.

4.Connect weld cables to weld output terminals as follows: Electrode holder cable to weld output terminal labeled ELECTRODE, and work clamp cable to weld output terminal labeled WORK.

IMPORTANT: Once weld cables are connected to the unit, the Selector Switch position provides the desired DC polarity or AC to the weld output terminals.

5.On all welding generator models except BIG 30A DIESEL, reinstall components as follows:

a.Reinstall and secure top cover.

b.Reinstall and secure the air cleaner hose onto the engine intake manifold.

6.On BIG 40 DIESEL, BIG 40G, and BIG 50 DIE- SEL models: Reinstall and secure the muffler onto the exhaust pipe.

7.Close and secure both side doors.
