MOVING PARTS can injure.

• Keep guards in place.

• Keep away from moving parts.

• Only qualified personnel should install, use or service this equipment.

CAUTION

Any increase of the high idle engine RPM by changing the governor setting or overriding the throttle linkage will cause an increase in the AC auxiliary voltage. If this voltage goes over 140 volts, wire feeder control circuits may be damaged. The engine governor set- ting is preset at the factory — do not adjust above RPM specifications listed in this manual.
