2. Loosen the 2 setscrews on the cylinder.
3. Turn the adapter until it stops:
• Counter Clockwise (CCW) to change to closed
center (creates gap)
• Clockwise (CW) to change to open center (clos-
es gap)
4. Tighten the two setscrews.
DIE INSTALLATION
Each crimping head has two die holders: one station-
ary and one moved by hydraulic ow when the trigger
is squeezed.
To install dies, follow the instructions below for your
model of crimping head.
1.
WARNING
Installing dies in the tools with the hydraulic hoses
connected can cause severe personal injury or
equipment damage.
To prevent accidental start-up, always disconnect the
hoses before installing dies.
If the hydraulic hoses are connected:
• Turn the hydraulic system control valve OFF.
• Disconnect rst the hydraulic input (supply)
hose, then the output (return) hose.
2. Clean the surfaces of the die holder to remove any
dirt or grease.
3. Select the dies for the task:
• If the die load has not been veried, select blank
dies and verify die load.
PRE-OPERATION
Careful inspection of the tool and hydraulic system be-
fore startup is important for safe, reliable operation of the
tool.
The following items should be checked daily at the start
and the end of each work shift.
1. Make sure the proper dies are securely in place. Op-
erating the tool without dies can deform the crimping
heads. Refer to Die Installation for instructions.
2. Connect hoses. Wipe all hose couplers with a clean,
lint-free cloth before making connections. Dirty cou-
plers can contaminate the hydraulic lines and pre-
vent a good seal at the connection.
3. Check all fasteners for tightness.
4. Check the equipment for oil leaks. If leaks are ob-
served, do not use the tool; have the equipment ser-
viced before use.
5. Check the tool and hydraulic system for proper op-
eration and performance.
6. If the equipment does not appear to operate prop-
erly, have it serviced before use.
7. Periodically verify the crimping force of the tool. Re-
fer to Die Load Verication.
SETUP AND TEST
• Never operate the tool without dies. Operating with-
out dies can deform the crimping head (retainer die
yoke or C-frame).
• If this happens, the dies cannot be installed and the
crimping head must be replaced.
• Never install the dies while the hydraulic hoses are
connected to the tool.
• Verify the crimping force before operating the tool.
OPEN CENTER/CLOSED CENTER
SETUP
The CT04 Hydraulic Crimping Tool can be congured
for either open-center or closed-center operation. The
current setting is easily determined by looking at the gap
between the adapter and the cylinder:
TO CHANGE THE CURRENT SETTING:
1. Remove the hydraulic hose coupling from the return
port on the tool, if one is installed. When making
the change from CC to OC, hydraulic uid may be
trapped in the tool, preventing complete movement
of the adapter. Remove the return coupling to allow
the hydraulic uid to escape.
