MAINTENANCE

ENGINE SPEED ADJUSTMENTS

Any increase in the engine RPM by changing the governor
setting or overriding the throttle linkage will cause an
increase in the A.C. auxiliary voltage.  If this voltage goes
above 140 volts, the control circuits of the WFM and wire
feeders will be damaged.  The engine governor setting is pre-
set at the factory -- do not adjust above RPM specifications
listed in the engine welder operating manual.
