WARNING:
DISPOSE OF HYDRAULIC OIL IN ACCORDANCE WITH ALL ENVIRONMENTAL LAWS AND
REGULATIONS APPLICABLE IN YOUR AREA.
Disconnect hydraulic hoses (28) and air line from manifold-handle (29) and drain hydraulic hoses (28). Push piston assy
(6) back to rear of the cylinder (3) to empty all oil from the tool. Push piston ass'y (6) to the front of the cylinder (3).
Unscrew socket head cap screw (12) from retaining ring (11) use a spanner wrench to remove retaining ring. Push
piston ass'y (6) back until cylinder cap ass'y (10) falls out of cylinder (3). Push piston ass'y (6) out the rear of the
cylinder (3). Using a small blunt object, remove o'rings and back-up rings from components.
Clean parts mineral spirits or other o'ring compatible solvent being sure to clean o'ring grooves. Inspect components
for scoring, excessive wear or damage.
Reassembly sequence is opposite of disassembly. (See Filling and Bleeding instructions.)
IMPORTANT:
Be sure to use thread sealant on all hydraulic fittings, Loctite® 30534 or similar Teflon® infused pipe
dope is recommended.
properly applied, pieces of Teflon may enter the hydraulic system and cause malfunction or damage.
Use 1 1/2 wraps of tape on each thread. Cut off all loose tape ends. Tighten until fitting feels snug and
then go 1/2 to a full turn past that point.
HANDLE
To inspect air cylinder bore, remove only flat head cap screws (61) & base cover (60). Any further disassembly will
require removal of the manifold-handle (29) first.
For complete disassembly, start by removing flat head cap screws (61) & base cover (60). Next, holding tool upright,
remove six socket-head cap screws (31). Lift manifold-handle (29) from handle (27) and set aside o'ring (23) and gasket
(30). Empty all hydraulic oil into a container.

Remove cotter pin (56). Place piston rod wrench (741511) down into top of handle, into the slot of piston rod assy (36)
and remove slotted nut (55) then unscrew and remove piston rod assy (36) from air piston (54). Insert threaded end of
power cylinder assy tool (704151) into bottom of air cylinder and remove air piston (54).
After removal of air piston (54), slide piston rod assy (36) back up the end of its travel. Using packing plug wrench
(756151) remove packing plug (42). With packing plug removed, power cylinder (33) can be tapped out by lowering
power cylinder tool (704151) down into top of handle (27) onto top of power cylinder (33).
To reassemble the handle, reverse the above procedure, being certain that all o'rings are properly lubricated before
installation. Attach the seal guide (870201) to the piston rod assy (36) and with a mallet, tap the piston rod assy (36)
through the packing plug (42).
AIR VALVE
WARNING:
DISCONNECT TOOL FROM ITS AIR SOURCE BEFORE DISASSEMBLY.
To disassemble, first disconnect tool from its air source. Remove retaining ring (51) and muffler (50). Thread valve
extractor (S1178) in end of valve plug (49) and pull it out. Using the same procedure, pull out valve spool ass'y (47).
NOTE: It should never be necessary to remove valve sleeve (44) unless the ports in the valve sleeve (44) are plugged
from contaminated air. If it is suspected that the ports are plugged up, use needle nose pliers to grasp end of spring
(45), turning clockwise and pulling to dislodge from groove in casting. With spring (45) removed, valve sleeve (44) can
be pulled out using valve sleeve removal tool (870207).
