Maintenance
Safety Precautions:
•
Have qualified personnel do maintenance and trou-
bleshooting work.
•
Turn the engine off before working inside the machine.
•
Remove guards only when necessary to perform
maintenance, and replace them when the maintenance
requiring their removal is complete.
•
If guards are missing from a machine, obtain
replacements from a Lincoln Distributor. (See
Operating manual Parts List.)
Read the Safety Precautions in the front of this manual and the
engine instruction manual before working on this machine.
Keep all equipment safety guards, covers and devices in position
and in good repair. Keep hands, hair, clothing and tools away from
gears, fans and all other moving parts when starting, operating or
repairing the equipment.
Routine Maintenance:
1.
At the end of each day’s use, refill the fuel tank to minimise
moisture condensation in the tank. Running out of fuel
tends to draw dirt into the fuel system. Also check the
crankcase oil level and add oil if indicated.
2.
Oil - Maintenance schedule for changing the oil and oil filter
after running-in can be found in the Engine Manual. More
frequent oil changes are required with dusty, high
temperature and other severe operating conditions. Refer
to the maintenance section of the Engine Owner’s Manual
for more information.
Note
: Engine life will be reduced if the oil and oil
filter are not changed according to the manufacturer’s rec-
ommendations.
3.
Air Cleaner - Petrol engine
- With normal operating
conditions, the maintenance schedule for cleaning and re-
oiling the foam pre-filter is every 25 hours and replacement
of the air cleaner filter, every 100 hours. More frequent
servicing is required with dusty operating conditions. Refer
to the maintenance section of the Engine Owner’s Manual
for more information.
Diesel engine
- with normal operating conditions check
the oil level in the air cleaner daily. Refer to engine manual
for other service and oil changing intervals.
4.
Refer to the maintenance section of the Engine Owner’s
Manual for the maintenance schedule, spark plug servicing
(petrol engine), cooling system servicing and fuel filter
replacement.
5.
Blow out the machine with low pressure air periodically. In
particularly dirty locations, this may be required once a
week.
See page 18 for Ground Test Procedure.
Engine Adjustments:
Adjustments to the engine are to be made only by a Lincoln
Service Centre or an authorised 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.
Before fitting replacement brushes, twist the brush pigtail at its
entrance to the brush until the strands are tightly packed and no
part of the pigtail protrudes beyond the brush surface in the pigtail
slot. When the brush is placed in the holder, clear the pigtail from
the side of the holder to allow free radial movement of the brush.
Sand new brushes by placing a piece of sandpaper between the
brushes and the slip ring with the abrasive side against the
brushes. With light finger pressure on the brushes, pull the
sandpaper around the circumference of the rings only until
brushes are properly seated. Stone the slip rings with a 320 grit
sanding stone. Slip rings must be clean and free from oil and
grease.
Battery:
Gases from battery can explode
- Keep sparks, flame and cigarettes away from
battery.
To prevent Explosion when:
Installing a new battery
- disconnect negative
cable from old battery first and connect to new
battery last.
Connecting a Battery Charger
- Remove battery
from welder by disconnecting negative cable first
then positive cable and battery clamp. When
reinstalling, connect negative cable last.
Using a Booster
- connect positive lead to battery
first then connect negative lead to engine foot.
Also see page 9 for other battery information.
WARNING
Make certain that the oil filler cap is securely tightened
after checking or adding oil. If the cap is not tight, oil
consumption can increase significantly which may be
evidenced by white smoke coming from the exhaust.
CAUTION
Overspeed is hazardous: The maximum allowable high
idle speed for this machine is 3400 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.
WARNING
Do not attempt to polish slip rings while engine is running
