3. Change the crankcase oil at regular intervals using
the proper grade of oil as recommended in the
engine operating manual.
4. Change the oil filter in accordance with the
instructions in the engine operator’s manual.
When the filter is changed, add a quart of oil to the
crankcase to replace the oil held in the filter during
operation.
5. Inspect the air filter daily - more often in dusty
conditions. When necessary, clean or replace.
The filter should never be removed while the
engine is running.
6. Change the diesel fuel filters every 500 hours of
operation.
7. Fan belts tend to loosen after the first 30 or 40
hours of operation. Check and tighten if
necessary. DO NOT OVERTIGHTEN.
8. Put a drop of oil on the “Current Range Selector”
shaft at least once every month.
9. See the engine manufacturer’s Operating Manual
for detailed engine maintenance and
troubleshooting instructions.
Cooling System
The 350-SA is equipped with a pressure radiator.
Keep the radiator cap tight to prevent loss of coolant.
Clean and flush the cooling system periodically to
prevent clogging the passage and overheating the
engine. When antifreeze is needed, always use the
permanent type.
Bearings
This welder is equipped with a double-shielded ball
bearing having sufficient grease to last indefinitely
under normal 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 equipment. More bearing failures are caused
by dirt introduced during greasing than from
insufficient grease.
Commutator & Brushes
Uncovered rotating equipment can be dangerous.
Use care so your hands, hair, clothing or tools do
not catch in the rotating parts. Protect yourself
from particles that may be thrown out by the
rotating armature when stoning the commutator.
------------------------------------------------------------------------
The generator brushes are properly adjusted when
the welder is shipped. They require no particular
attention. DO NOT SHIFT THE BRUSHES or adjust
the rocker setting.
Periodically inspect the commutator, slip rings and
brushes by removing the covers. DO NOT remove or
replace these covers while the machine is running.
Commutators and slip rings require little attention.
However, if they are black or appear uneven, have
them cleaned by an experienced maintenance man
using fine sandpaper or a commutator stone. Never
use emery cloth or paper for this purpose.
Note: If the welder is used in dirty or dusty locations,
or if the welder is not used for prolonged periods of
time, it may be necessary to clean the commutator
and slip rings more often.
Replace brushes when they wear within 1/4” of the
pigtail. A complete set of replacement brushes should
be kept on hand. Lincoln brushes have a curved face
to fit the commutator. Have an experienced
maintenance man seat these brushes by lightly
stoning the commutator as the armature rotates at full
speed until contact is made across the full face of the
brushes. After stoning, blow out the dust with low
pressure air.
To seat the slip ring brushes, position the brushes in
place. Then slide one end of a piece of fine
sandpaper between slip rings and brushes with the
coarse side against the brushes. With slight
additional finger pressure on top of the brushes, pull
the sandpaper around the circumference of the rings,
in direction of rotation only - until brushes seat
properly. In addition, stone slip ring with a fine stone.
Brushes must be seated 100%.
Arcing or excessive exciter brush wear indicates a
possible misaligned shaft. Have an authorized Field
Service Shop check and realign the shaft.
