MAINTENANCE

WARNING

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.

-----------------------------------------------------------------------

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or electrode with skin or wet clothing.

Insulate yourself from work and ground

Always wear dry insulating gloves.

--------------------------------------------------------

----------------

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.

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 cur- rent control through its entire range frequently. Good practice is to turn the handle from maximum to mini- mum setting twice each morning before starting to weld.

3.Put a drop of oil on the “Current Range Selector” shaft at least once every month.

4.When necessary, remove the sediment bowl, if so equipped, from beneath the fuel tank and clean out any accumulated dirt and water.

5.Follow the engine service schedule in this manual and the detailed maintenance and troubleshooting in the engine manufacturer’s manual.

Cooling System

The Classic III & III D are each equipped with a pres- sure radiator. Keep the radiator cap tight to prevent loss of coolant. Clean and flush the cooling system periodically to prevent clogging the passage and over- heating the engine. When antifreeze is needed, always use the permanent type. Capacity = 9.3 qts.

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 con- stantly or in excessively dirty locations, it may be nec- essary 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 insuffi- cient grease.

Commutator and Brushes

WARNING

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 rotat- ing armature when stoning the commutator.

------------------------------------------------------------------------

Shifting of the commutator brushes may result in:

-Change in machine output

-Commutator damage

-Excessive brush wear

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.
