Assembly
When assembling parts, refer to Parts illustrations for
correct orientation and placement of parts.
Clean all parts with solvent (take care to protect eyes),
then dry thoroughly. Do not expose O-rings or other
packing components to solvent for long periods of time.
Inspect all parts as they are assembled for signs of
damage, wear, cracks, etc. Do not install any parts
which appear to be damaged.
Apply hydraulic fluid or O-ring lubricant to all O-rings
and all metal surfaces which O-rings must slide over.
When installing an O-ring over a sharp edge, use a
rolling action to avoid damage to O-ring.
Wherever assembled parts cause metal-to-metal
contact, coat the surfaces with hydraulic fluid or O-ring
lubricant.
Handle and Valve
1. Install O-ring (41), spool (40), spring (42), cap (43), to
upper end of insulated valve body handle (75).
2. Install O-ring (39), stem (38) and stem retainer (37)
on lower end of valve body handle (75).
3. Position trigger (34) on valve handle (75), align-
ing holes in each component. Install trigger pivot
pin (35) and secure in place with two 5/32 external
retaining rings (36).
4. Position trigger guard (64) on handle (75) and secure
with 1/4-inch round slotted head cap screws (66)
and internal tooth lock washers (65).
5. Install O-ring (47) onto handle (75).
6. Install O-ring (48) on return tube assembly (49).
Install return tube assembly in handle and secure in
place with 3/4-inch internal retaining ring (52).
7. Install rod seal support (54), bushing (57), O-ring (55)
and seal (56) and O-ring (47) on upper end (59).
8. Clamp upper end (59) in a vise and thread cylin-
der (53) onto upper end (59). Tighten with a strap
wrench.
9. Install piston seals (61) and back-up washers (60) on
piston and rod assembly (63).
10. Install bypass seal (51), seal retainer (50) in bottom
end of piston and rod assembly (63) and secure into
place with 3/4" internal retaining ring (52).
11. Slide piston and rod assembly (63) in cylinder and
upper end.
12. Thread handle assembly (75) onto cylinder (53).
Thread nut (14) onto upper end (59).
Outer Extension Tube and Inner Pull Rod
1. Apply Loctite 242-05 (F015774) or equal, onto both
threaded ends of the inner extension rod assembly
(6). Follow the manufacturer’s instruction for curing.
2. Thread the extension rod end (7) onto the inner
extension rod (6). Thread the swivel assembly (1)
onto the lower end of the inner extension rod (6).
Thread the other end of swivel (1) into the shaft of
piston rod (63). Tighten everything securely, using
two 1/2 inch open-end wrenches on the wrench
flats milled in both components.
3. If removed, install the hand grip (11) onto the outer
extension tube (10). The nearest end of the hand
grip (11) must be 5 inches from the end of the outer
extension tube (10).
4. Slide the extension connector nut (16), tapered end
first, onto the outer extension tube (10). Install the
upper collet ring (13), beveled end first, and clamp
collet (12) onto the outer extension tube (10). Install
the clamp ring (9) to secure the components to the
tube. Slip the lower collet ring (8) onto the end of the
outer extension tube (10).
5. Apply a liberal amount of grease (F015437) onto the
extension rod end (7) and inner extension rod (6).
Slide the outer extension tube (10) over the rod and
rod end (6, 7). Thread the extension connector nut
(15) onto the upper end (59). Tighten securely.
Cutter and Mounting Unit
1. Mount the cutter brace (2) and cutter hook (30) onto
the cutter mounting bracket (18). Loosely thread
the two 1/4-28 x 7/8 inch hex head cap screws (17)
and 1/4 inch lock washers (20). The cap screws (17)
must be installed through the brace (21), then the
mounting bracket (18), and finally into the threaded
holes in the hook (30).
2. Install the cutter blade (29) and brass washer (67)
between the brace (2) and hook (30). Align the holes
of all these components and insert the cutter bolt
(22). Thread the 3/8-24 hex nut (33) onto the cutter
bolt (22). Tighten the 3/8-24 hex nut (33) until some
drag is felt when the blade is opened or closed. The
cutter blade (29) should pivot around the cutter bolt
(22) with slight tension.
Note: The cutter hook (30) and cutter blade (29)
must fit together snugly. If they are too tight, the
cutter will not perform properly. If the fit is too loose,
the tool will not cut cleanly, and damage to the tool
may occur. Wood may jam in-between the hook and
cutter blade, springing them apart and permanently
bending one or the other.
