MAINTENANCE
WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts
such as output terminals or internal
wiring
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside
MOVING PARTS can injure.
• Do not operate with doors open or
guards off
• Stop engine before servicing
• Keep away from moving parts
• Remove guards only when necessary and replace when
work requiring removal is complete.
• Only qualified personnel should install, use, or service
this equipment.

ROUTINE MAINTENANCE

At the end of each day's welding, refill the fuel tank to minimize
moisture condensation in the tank. Also, running out of fuel tends
to draw dirt into the fuel system. Check the engine crankcase oil
levels.
If the fuel supply runs out while the fuel pump is operating, air
may be entrapped in the fuel distribution system. If this happens,
bleeding of the fuel system may be necessary. See the engine
instruction manual.

ENGINE AIR FILTER

The engine air filter element is a dry cartridge type. It is located
above the engine. It can be cleaned and re-used; however,
damaged elements should not be washed or re-used. Remove
loose dirt from element with compressed air or water hose
directed from inside out. Compressed Air: 100 psi maximum. The
filter should never be removed while the engine is running.

PERIODIC MAINTENANCE

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. The current control reactor brushes are self-lubricating and
should not be greased. Keep the contacts clean. This control
should be moved from maximum to minimum daily to prevent
the controls from sticking.
3. See the engine Instruction Manual for periodic engine
maintenance information. Change the crankcase oil at regular
intervals using the proper grade of oil as recommended in the
engine operating manual. Change the oil filter in accordance
with the instructions in the engine operating manual. When
the oil filter is changed add one quart of oil to the crankcase
to replace the oil held in the filter during operation.
4. Belts tend to loosen after the first 30 or 40 hours of operation.
Check the cooling fan belt and tighten if necessary. DO NOT
OVER TIGHTEN.

Bearing Maintenance

(For Code 11605 only)
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.
