PIPELINER® 200D PERKINS
SAFETY PRECAUTIONS
GENERAL INSTRUCTIONS
1. Blow out the welder and controls with an air hose at
least once every two months. In particularly dirty
locations, this cleaning may be necessary once a
week. Use low pressure air to avoid driving dirt into
the insulation.
2. “Current Range Selector” contacts should not be
greased. To keep the contacts clean, rotate the cur-
rent control through its entire range frequently.
Good practice is to turn the handle from maximum
to minimum setting twice each morning before start-
ing to weld.
3. Put a drop of oil on the “Current Range Selector”
shaft at least once every month.
4. When necessary, remove the sediment bowl from
beneath the gas tank and clean out any accumulat-
ed dirt and water. Replace the fuel filter in the fuel
line as needed.
5. See the engine manufacturers operation manual for
detailed engine maintenance and troubleshooting
instructions.
COOLING SYSTEM
The Pipeliner® 200D is equipped with a pressure radi-
ator. Keep the radiator cap tight to prevent loss of
coolant. Clean and flush the cooling system periodical-
ly to prevent clogging the passage and overheating the
engine. When antifreeze is needed, always use the
permanent type.
ENGINE MAINTENANCE
Refer to the Engineʼs operation and mainte-
nance manual for additional information on
the engine.
Have qualified personnel do the maintenance
work. Turn the engine off before working inside
the machine. In some cases, it may be necessary
to remove safety guards to perform required
maintenance. Remove guards only when neces-
sary and replace them when the maintenance
requiring their removal is complete. Always use
the greatest care when working near moving
parts.
Do not put your hands near the engine cooling
blower fan. If a problem cannot be corrected by
following the instructions, take the machine to
the nearest Lincoln Field Service Shop.
