Have qualified personnel do the maintenance
work. Turn the engine off before working inside
the machine. In some cases, it may be neces-
sary to remove safety guards to perform
required maintenance. Remove guards only
when necessary and replace them when the
maintenance requiring their removal is com-
plete. Always use the greatest care when work-
ing 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.

WARNING
4. Inspect the air filter daily - more often in dusty condi-
tions. When necessary, clean or replace. The filter
should never be removed while the engine is running.
The air filter element part number is Donaldson
#181050 or Nelson #70206N.
5. Drain any accumulated water from the engine fuel fil-
ter/water separator daily. Change the filter every 1000
hours of operation. Order Deutz fuel filter #117-4482
from your local Deutz Service Center. A fuel filter ele-
ment without the water separator may be used in
place of the standard element. Order Deutz #117-
4696.
6. Fan belts tend to loosen after the first 50 hours of
operation. Check engine Operation Manual and
tighten if necessary. DO NOT OVER TIGHTEN.
7. Put a drop of oil on the “Current Range Selector” shaft
at least once every month.
8. See the engine manufacturerʼs Operation Manual for
detailed engine maintenance and troubleshooting
instructions.
COOLING SYSTEM
The Classic II is equipped with an air cooled Deutz
engine. Clean the engine cooling system periodically to
prevent clogging the air passages on the cylinder heads
and oil cooler and overheating the engine. Consult the
Engine Operation Manual. It is important that the
welder is located in a manner which will provide an unre-
stricted flow of clean, cool air.
BEARINGS
This welder is equipped with a double-shielded ball bear-
ing having sufficient grease to last indefinitely under nor-
mal service. Where the welder is used constantly or in
excessively dirty locations, it may be necessary to add
one half ounce of grease per year. A pad of grease one
inch wide, one inch long, and one inch high weighs
approximately one half ounce. Over-greasing is far worse
than insufficient greasing.
When greasing the bearings, keep all dirt out of the area.
Wipe the fittings completely clean and use clean equip-
ment. More bearing failures are caused by dirt introduced
during greasing than from insufficient grease.
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.
3. Change the crankcase oil and oil filter after the first
50 hours of operation and thereafter at 750 hour
intervals using the proper grade of oil. See recom-
mendations in the engine Operation Manual.
Order Deutz oil filter #117-4416 or #117-4417 from
