hose, then the output (return) hose.
2. Clean the surfaces of the die holder to remove any
dirt or grease.
3. Pull the pin out to release the latch.
4. Rotate the latch away from the head to provide
access to the nib/nest die.
5. To release the nib/nest die, drive the roll pin out of
the center of the latch.
6. Remove the nib/nest die by rotating it out and around
the small pivot pin inside the latch.
7. Insert the new nib/nest die, rotating it around the
pivot pin as in step 6. Make sure the nib/nest die is
oriented so the notched side faces the pivot pin.
8. Press the nib/nest die rmly until it locks into place.
9. Drive the roll pin into the center of the latch to retain
the nib/nest die.
10. Close the latch. Insert the latch pin.
HYDRAULIC HOSE CONNECTION
Make sure the hydraulic system control valve is in the
OFF position when coupling or uncoupling the hoses.
Failure to do so may result in damage to the quick
couplers and cause overheating of the hydraulic system.
Before installing the hoses, wipe the ttings and the
entire length of the hoses with a clean, dry, lint-free cloth
to remove any dirt or moisture. Dirty connections can
contaminate the hydraulic uid, causing rapid wear and
early failure of internal pars.
Check the ow indicators (arrows) stamped on the
couplers to ensure oil ows in the proper direction. The
female coupler on the tool is the inlet coupler.
Connect the output (return) hose rst and disconnect it
last to minimize trapped pressure within the tool.
1. Connect the output hose to the OUT or “T” port on
the tool.
2. Connect the input hose to the IN or “P” port.
3. Be sure all hose connections are tight.
DIE LOAD VERIFICATION
1. Use test slugs to verify the crimping force in the tool.
2. Connect the tool to an appropriate hydraulic power
source. Follow the Hydraulic Hose Connection
safety guidelines and instructions in this section. If
possible, use the hydraulic power source you plan to
use for crimping.
3. Position the test slug within the nibs.
4. Actuate the tool to squeeze the test slug.
5. Release the test slug and then measure it.
If the indicated value is low or high, and the system
pressure relief valve setting is greater than 1650 psi
(114 bar), adjust the relief valve on the CT to obtain
the correct die load.
6. When the value is within the acceptable range,
turn the hydraulic system control valve OFF and
disconnect the hoses from the tool.
OC/CC SETTING
Check the open-center/closed-center (OC/CC) setting
on the tool. The current setting is easily determined by
looking at the gap between the adapter and the cylinder,
see Figure 2.
• Open Center: No gap
• Closed Center: Approximately 1/4-inch (6.4-mm)
gap
If the setting is not correct for your hydraulic system,
follow “Open center/closed center setup” on page 10
to make the change.
CHECK POWER SOURCE
Using a calibrated ow meter and pressure gauge,
check the hydraulic power source at the tool’s input port.
Make sure the system maintains an operating ow in the
range of 3–9 GPM/11–34 LPM within a pressure range
of 1650–2000 psi /114–140 bar.
The hydraulic uid temperature should be at least
80°F/27 °C for this test.
CONNECT HOSES
1. Wipe all hose couplers with a clean, lint-free cloth
before making connections.
2. Connect hoses from the hydraulic power source to
the tool ttings or quick disconnects. Connect the
return hose rst and disconnect it last to minimize
trapped pressure within the wrench.
3. Observe the ow indicators stamped on the main
body assembly and the hose couplers to ensure
that the ow is in the proper directions. The female
couple on the tools “IN” port is the inlet (pressure)
coupler.
Note: If the uncoupled hoses are left in the sun,
pressure increase within the hoses can make them
dicult to connect. Whenever possible, connect the
free ends of the hoses together.
TOOL RELIEF VALVE ADJUSTMENT
The relief valve on a universal pressure CT can be
adjusted to increase or decrease the tool’s crimping
force. Standard CT’s do not have a relief valve.
