4.Slide the new element onto the grommet post on the bottom of the filter header until the element no longer easily moves up into the filter header. Now rotate the element (may take almost 1 full turn) with a slight upward pressure until the element begins to further engage the header. With the proper orientation now established apply additional pressure to seat the ele- ment in the filter header. You should feel the element “pop” into place when properly seated.

Note: The element will only go on one way. Never use excessive force when mounting the element to the header.

5.Slide the quick change ring up over the element and rotate counter clockwise until an audible click or pop is heard. If you do not hear the click you have not rotat- ed the ring far enough and the element is not in the locked position. Another indication that the ring is in the locked position is that one set (it doesn’t matter which one) of arrows located on the outside of the ring should be located directly under the air vent valve.

6.Open the fuel shutoff valve (lever in line with the hose).

7.Open the air vent valve on the front of the filter head- er until fuel emerges free of air bubbles and then close the air vent valve.

Note : Consult your engine operation manual for infor- mation on air bleeding the entire fuel system.

SECONDARY FUEL FILTER

The Secondary Fuel Filter is a spin on cartridge type mount directly to the engine. Consult your engine opera- tion manual for complete information on service intervals and element changing procedures.

COOLING SYSTEM

The cooling system of the Deutz engine needs to be checked and cleaned periodically. Consult the engine owners manual for the proper frequency and procedure.

COOLING BLOWER BELT

The following procedure should be followed to replace the cooling blower belt:

1.Allow the machine to cool.

2.Unfasten and slide the battery holder out from the welder.

3.Disconnect the negative battery cable.

4.Remove engine case side.

5.Loosen air cleaner hose clamp and detach hose.

6.Remove the engine end panel with air box and air clean- er attached for access to the engine.

7.Loosen the alternator mounting bolts and rotate the alternator towards the engine.

8.Remove the old cooling blower belt and install a new one.

9.Adjust the cold belt tension to 63-73 lbs. midway between any two pulleys.

10.Reinstall the air cleaner hose, engine case side and end panel. Reattach the negative battery cable. Slide in and refasten the battery holder.

11.Check the cooling blower belt tension after 100 hours of operation. (Follow steps 1,2,3,4,5,6,9 & 10)

BATTERY HANDLING

WARNING

GASES FROM BATTERY can explode.

•Keep sparks, flame and cigarettes away from bat-

tery.

To prevent EXPLOSION when:

•INSTALLING A NEW BATTERY - disconnect nega- tive cable from old battery first and connect to new battery last.

•CONNECTING A BATTERY CHARGER - Remove bat- tery from welder by disconnecting negative cable first, then positive cable and battery clamp. When reinstalling, connect negative cable last. Keep well ventilated.

• USING A BOOSTER - connect positive lead to bat- tery first then connect negative lead to engine foot.

BATTERY ACID CAN BURN EYES AND SKIN.

•Wear gloves and eye protection and be careful

when working near battery. Follow instructions printed on battery.

PREVENTING ELECTRICAL DAMAGE

1.When replacing, jumping, or otherwise connecting the battery to the battery cables, the proper polarity must be observed. Failure to observe the proper polarity could result in damage to the charging circuit. The positive (+) battery cable has a red terminal cover.

2.If the battery requires charging from an external charg- er, disconnect the negative battery cable first and then the positive battery cable before attaching the charger leads. Failure to do so can result in damage to the internal charger components. When reconnecting the cables, connect the positive cable first and the negative cable last.

PREVENTING BATTERY DISCHARGE

If you have an ignition switch, turn it off when engine is not running.

PREVENTING BATTERY BUCKLING

Tighten nuts on battery clamp until snug.
