The filter should never be removed while the engine is running. The air filter element part number is Donaldson #181050 or Nelson #70206N. 5. Drain any accumulated water from the engine fuel filter/ water separator daily. Change the filter every 1000 hours of operation. Order Deutz fuel filter #117-4482 from your local Deutz Service Center. A fuel filter element without the water separator may be used in place of the standard element. Order Deutz #1174696. 6. Fan belts tend to loosen after the first 50 hours of operation. Check engine Operation Manual and tighten if necessary. DO NOT OVER TIGHTEN. 7. Put a drop of oil on the “Current Range Selector” shaft at least once every month. 8. See the engine manufacturer’s Operation Manual for detailed engine maintenance and troubleshooting instructions. COOLING SYSTEM The Classic II is equipped with an air cooled Deutz engine. Clean the engine cooling system periodically to prevent clogging the air passages on the cylinder heads and oil cooler and overheating the engine. Consult the Engine Operation Manual. It is important that the welder is located in a manner which will provide an unrestricted flow of clean, cool air. 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. CLASSIC II DEUTZ D-2 MAINTENANCE D-2 Commutator and Brushes Idler Maintenance 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. Shifting of the 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. 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 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 WARNING seated 100%. 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. Arcing or excessive exciter brush wear indicates a possible misaligned shaft. Have an authorized Field Service Shop check and realign the shaft. 1. The solenoid plunger must work freely and not bind. Dust the plunger about once a year with graphite powder. 2. Proper operation of the idler requires good grounding of the printed circuit board, reed switch, and battery. 3. If desired, the welder can be used without automatic idling by setting the “Idler” switch to the “High” position. CAUTION Before doing electrical work on the idler printed circuit board, disconnect the battery. When installing a new battery or using a jumper battery to start the engine, be sure the battery polarity is connected properly. The correct polarity is negative ground. Damage to the engine alternator and the printed circuit board can result from incorrect connection. Nameplates Whenever routine maintenance is performed on this machine - or at least yearly - inspect all nameplates and labels for legibility. Replace those which are no longer clear. Refer to the parts list for the replacement item number. CLASSIC II DEUTZ E-1 E-1 TROUBLESHOOTI...
