Engine Adjustments
OVERSPEED IS HAZARDOUS
The maximum allowable high idle speed for this
machine is 3750 RPM, no load. Do NOT tamper
with governor components or setting or make any
other adjustments to increase the maximum
speed. Severe personal injury and damage to the
machine can result if operated at speeds above
maximum.
------------------------------------------------------------------------
Adjustments to the engine are to be made only by a
Lincoln Service Center or an authorized Field Service
Shop.
Slip Rings
A slight amount of darkening and wear of the slip rings
and brushes is normal. Brushes should be inspected
when a general overhaul is necessary. If brushes are
to be replaced, clean slip rings with a fine emery paper.
Do not attempt to polish slip rings while engine is
running.
Battery
1. When replacing, jumping, or otherwise connecting
the battery to the battery cables, the proper
polarity must be observed. Failure to observe
the proper polarity could result in damage to the
charging circuit. The positive (+) battery cable
has a red terminal cover.
2. If the battery requires charging from an external
charger, disconnect the negative battery cable
first and then the positive battery cable before
attaching the charger leads. Failure to do so
can result in damage to the internal charger
components. When reconnecting the cables,
connect the positive cable first and the negative
cable last.
Hardware
Both English and Metric fasteners are used in this
welder.
