manual abstract
Remove all accessories from gun before servicing. Items referenced ( ) will correspond with list items. 1 Legs: Loosen set screws (23) and pull legs (not shown) straight out. Inspect legs for damage and straightness, replace if necessary. 2 Chuck (Not Shown): Insert chuck key into chuck adapter and turn key 180 degrees. Inspect chuck for damage. If taper on chuck appear worn out replace chuck. 3 Dust Bellows (3): Remove dust bellows by sliding over end of chuck adapter. The bellows prevent contaminates from entering the internal mechanisms of the gun. If bellows has holes or is torn, replace. 1 2 3 4 5 6 8 7 12 13 14 11 10 23 9 24 4 25 27 26 29 30 28 27 22 23 33 35 36 31 32 37 34 15 16 17 18 19 20 21 38 40 41 42 39 4 Chuck Adapter (2): Unscrew chuck adapter counter clockwise from cable clamp adapter. Important that chuck adapter is tight on cable clamp adapter to form a tight connection. An effective way of removing the adapter is to insert a round rod through two of the chuck eject holes. Replace chuck adapter if inside surface or threads are pitted or damaged. 5 Front Cover Nuts (1): The front cover is held on with two nuts. Use a 3/4 inch wrench to remove them. Inspect the plastic bearing (4) for damage or excessive wear. 6 Front Cover (5): If gun is equipped with a plunge dampener it is located in the front cover. Inspect front cover for cracks and replace if cracked. The front cover prevents dirt from entering the internal mechanism and maintains alignment of internal components. 7 Plunge Dampener (7): The dampener is inside the front cover. It pulls straight out and pushes straight back in. When the plunge dampener is activated by a finger it should offer continuous resistance over the entire range of travel. The plunger should then return, by itself, to full extension. If this is not the case the dampener needs to be replaced. 8 Cable Clamp Adapter (8): Remove two #10.32 x 5/8 socket head cap screws (6) from cable clamp adapter. The cable clamp adapter will separate from the lifting rod. Maneuver the cable clamp adapter forward between the leg inserts. Remove the #8.32 x 1/2 cap screw (11) from the back of the cable clamp adapter (8). Inspect threads on cable clamp adapter. If threads are damage replace cable clamp adapter. This item transfers all the weld current. If there is damage to the threads, arcing will continue and potentially fuse all the components together. 9 Lifting Mechanism: The lifting mechanism consists of the lifting rod (12), main spring (13), lift release (14), moveable core (15.20) and core return spring (21). To disassemble, press the lift release ring tight against the moveable core and pull the lifting rod out of the assembly. All components listed above, will come apart. 10 Lifting Rod (12): Inspect lifting rod for wear or damage. The brass inserts should show no signs of loosening. The steel shaft should not have any nicks on it. Run a finger over the shaft. If you can feel grooves from the lifting bearing then the lifting rod is worn out. Typically the lifting rod and lift bearing should be replaced as a set. When reassembling, the shaft should have a light film of grease (a lithium based grease) applied. 11 Disassembly of Moveable Core (15 - 20): Remove snap ring (20) from shaft (18) of core assembly. The snap ring acts as a spring seat and is important to maintain proper spring tension. Where the core assembles into the bearing housing is another retaining ring (19). This retaining ring can be removed with a small flat bladed screw driver. After removing the second retaining ring the bearing housing (15) will separate from the core shaft. The lift bearing (16) and the lift bearing spring (17) can now be removed. When reassembling the lift bearing cage must oriented toward the liftbearing spring. Put a light film of grease (such as a lithium based grease) over the lift bearing and the lift bearing spring. 12 Handle Covers (35): Remove 3 flat head screws (36 - 37) that retain the handle cover. Inspect handle cover for breakage. 13 Weld Cable (40): The weld cable can lift out of the gun body. Be careful unthreading the internal weld cable (9) from inside the body. The internal and external weld cables can be unscrewed from the weld cable anchor plate (32). Note the orientation of the weld cable anchor plate. The radius corner goes toward the top of the body. Inspect the internal weld cable for frayed or broken wires. If starting to fray, the internal cable should be replaced. Inspect weld cable for fraying. Also inspect strain relief (38) for tears. Inspect cable jacketing for breaks, cuts or tears. If cable shows signs of damage or wear it should be replaced. In addition, inspect the weld.lok connector (39). If pitted or damaged, replace. Inspect weld cable to camlok joint to ensure there is no fraying of the weld cable. 14 Control Cable (42) (if desired): The control cable is removed by cutting the wires by the splice connectors. Inspect the control cable for damage. Thi...
