b. If the die load has been verified, select a set
of dies to match the sleeve or connector to be
crimped.
DIE LOAD VERIFICATION
With blank (test) dies installed, use a die load tester to
verify the crimping force in the tool before operating a
new crimping tool, before placing the tool in service after
storage or repair or periodically during normal use
1. Make sure blank (test) dies are installed in the die
holder. If not, follow the Die Installation instructions
at the beginning of this section.
2. Connect the tool to an appropriate hydraulic power
source. Follow the Hydraulic Hose Connection safe-
ty guidelines and instructions in this section. If pos-
sible, use the hydraulic power source you plan to
use for crimping.
3. Place the die load tester between the blank (test)
dies.
4. Actuate the tool and read the value shown on the
load tester indicator. The force should be 15 tons
(13,600 kg), depending on the pressure from the hy-
draulic power source.
5. If the indicated value is low and the system pressure
relief valve setting is greater than 1650 psi (114 bar),
adjust the relief valve on the CT to get the correct
die load.
If the indicated value is high, adjust the relief valve
on the CT to get the correct die load.
6. When the value is within the acceptable range, turn
the hydraulic system control valve OFF and discon-
nect the hoses from the tool.
7. Follow the Die Installation instructions at the begin-
ning of this section to remove the blank dies and
install the proper crimping dies.
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.
• Open Center: No gap
• Closed Center: Approximately 1/4-inch (6.4-mm)
gap
If the setting is not correct for your hydraulic system, fol-
low the instructions in this section, OC/CC Adjustment,
to make the change.
OPERATION
DIE CHECK
Make sure the dies installed in the tool match the sleeve
or connector to be crimped. If not, follow the instructions
in this section, Die Installation.
CHECK POWER SOURCE
Using a calibrated flowmeter and pressure gauge, check
the hydraulic power source at the tool's input port. Make
sure the system maintains an operating flow in the range
of 3-9 gpm/11-34 lpm within a pressure range of 1650-
2000 psi /114-140 bar.
The hydraulic fluid 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 fittings or quick disconnects. It is good prac-
tice to connect the return hose first and disconnect it
last to minimize or eliminate trapped pressure within
the wrench.
3. Observe the flow indicators stamped on the main
body assembly and the hose couplers to ensure
that the flow 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 difficult to
connect. Whenever possible, connect the free ends
of the hoses together.
OPERATION
Observe all safety precautions when operating the tool.
Read Safety and Hydraulic System Requirements, be-
fore operating the tool for the first time.
CONDUCTOR PREPARATION
1. If the conductor is insulated, remove the insulation
from the end of the conductor.
a. Use an insulation stripping tool. If a stripping
tool is not available, carefully shave the insula-
tion from the cable.
b. Be sure not to nick or cut the strands of the con-
ductor.
2. Remove any oxide or foreign matter from the ex-
posed conductor. A bright, shiny surface is required
for a good connection. Do not wire-brush tin-plated
copper conductors or tinned connectors.
