WARNING

ELECTRIC SHOCK can kill.

●Do not touch electrically live parts such as output terminals or inter- nal 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 com- plete.

●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, run- ning out of fuel tends to draw dirt into the fuel system. Check the engine crankcase oil level.

4.Belts tend to loosen after the first 30 or 40 hours of oper- ation. Check the cooling fan belt and tighten if necessary.

DO NOT OVER TIGHTEN.

ENGINE OIL CHANGE

The SAE-400 SEVERE DUTY is equipped with a convenient oil drain system. Drain the oil when the engine is warm to assure rapid and complete draining.

•Remove the oil filler cap and dipstick.

•To open drain valve, push handle away from valve and turn 90°.

•Drain oil into a suitable container.

•To close drain valve, turn handle 90° till handle snaps in the closed position.

•Refill engine with the recommended oil to the appropriate level. Replace dipstick and tighten the oil filler cap secure- ly.

Change the crankcase oil at regular intervals using the prop- er grade of oil as recommended in the Engine Operating Manual. Wash your hands with soap and water after handling used oil. Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take it in a sealed container to your local service station or recycling center for reclamation. Do not throw it in the trash, pour it on the ground or down a drain.

If the fuel supply runs out while the fuel pump is oper- ating, air may be entrapped in the fuel distribution sys- tem. If this happens, bleeding of the fuel system may be necessary. See the engine instruction manual.

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 pres- sure 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 oil filter in accor- dance with the instructions in the engine operating man- ual. When the oil filter is changed add one quart of oil to the crankcase to replace the oil held in the filter during operation.

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.
