WARNING:

Disconnect tool from its air source before disassembly.

CAUTION:

When replacing the dividers (510102), care should be taken to replace the retaining rings (S15) so they do not

block the air ports at the bottom of the cylinder assembly (510121) where the handle (510422) attaches. Use caution

not to nick or score i.d. bore.

* For a complete overhaul, SERVICE KIT (550000) is recommended.

Using a Truarc® plier, remove retaining ring (S15) which allows removal of back cap (541121) and cushion (510114).

Double nut front end of drawbolt (551136) using 1/4 - 28 nut, then remove connector bolt assembly (551121) permitting removal

of retaining ring (S15) and piston (510101).

Remove front retaining ring (S15) and withdraw front seal (510119).

Remove the front piston (510101), permitting removal of the sleeve (510104). The triple piston chambers are separated by dividers

(510102) which may be removed by removing the retaining rings (S15). It can be difficult to remove the pistons.

Gage Bilt recommends using an "L" shaped rod (like a hex wrench) to facilitate removal. Insert the short end in the middle of the piston

and pull the piston out. You will have to work it up and out evenly, being careful to keep the piston level so not to get it stuck.

The re-assembly sequence is the opposite of disassembly.

For complete disassembly.

Remove two button head cap screws (A-819).

Slide out 2 dowel screws (510215).

Remove and replace o'ring (400782).

Remove seal seat (510125) then remove and replace seal (510105).

Carefully pull actuator assembly (510127) with o'ring (400772) from handle assembly. Replace o'ring (400772) on actuator assembly

(510127).

Reassembly sequence is the opposite of disassembly.

Note: When reassembling, seal seat (510125) inserts into hole on actuator assembly (510127). (See image below).

When tool life is met, disassemble tool and remove all rubber o'rings, seals, wipers and collection bottle. All tool materials are

recyclable except rubber o'rings, seals and wipers. Dispose of rubber materials in accordance with the material safety datasheet.
