plete. Always use the greatest care when work-
ing near moving parts.

blower fan. If a problem cannot be corrected by
following the instructions, take the machine to
the nearest Lincoln Field Service Shop.

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
current control through its entire range frequently.
Good practice is to turn the handle from maximum
to minimum setting twice each morning before
starting to weld.

MAINTENANCE

3. Change the crankcase oil and oil filter after the first
50 hours of operation and thereafter at regular
intervals using the proper grade of oil. See the rec-
ommendations in the engine operation manual.
4. Inspect the air filter daily - - more often in dusty
conditions when necessary clean or replace. The
air filter should never be removed while the engine
is running. The air filter element part number is
Donaldson #181050 or Nelson #70206N.
5. 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. In an emergency, the fuel filter can
be back-flushed for continued use until a replace-
ment can be obtained.
6. Fan belts tend to loosen after the first 50 hours of
operation. Check engine operation manual and
tighten if necessary. DO NOT OVERTIGHTEN.
7. Put a drop of oil on the "Current Range Selector"
shaft at least once every month.
8. See the engine manufacturers operation manual
for detailed engine maintenance and troubleshoot-
ing instructions.

COOLING SYSTEM

The Pipeliner 200G is equipped with a pressure radia-
tor. Keep the radiator cap tight to prevent loss of
coolant. Clean and flush the cooling system periodi-
cally to prevent clogging the passage and overheating
the engine. When antifreeze is needed, always use
the permanent type. Capacity = 9.9 Qty. (9.4 liter)
Consult the engine owners manual for the proper fre-
quency and procedure.

nance manual for additional information on
