Crimping Machine
TH8-D206
Bulletin 4480-T22-US
PROBLEM: CRIMPER WILL NOT RUN AT ALL
The white rocker switch is also a circuit breaker. Check to see that the circuit breaker has not been
tripped
Check the wall outlet. The crimper comes from the factory wired for a 115 volt single phase circuit. Use
of extension cords or outlets with inadequate power can damage the motor . Do not run the crimper from a
portable power source.
Check the stop switch mounted to the switch bracket under the Micro-Crimp Adjuster. This is a normally
closed switch and if it does not close the crimper will not operate.
CAUTION: Do not operate the crimper with this switch jumpered as the pump will not shut off and the
brackets can be damaged.
Check the pneumatically actuated switch in the electrical box mounted on the motor. This switch controls
power to the motor and is actuated with air pressure from the pendant switch bulb.
PROBLEM: CRIMP DIAMETER TOO LARGE
Incorrect setting of the Micro-Crimp Adjuster. Check crimp specifications.
(NOTE: All published machine settings are approximate. To correct for slight variances, the gauge settings
may be adjusted for the specific hose, fitting and size combination.)
Incorrect die being used. Each die has a range of approximately 3mm (.120 in) above the closed diameter
of the die. The closed diameter is the die size stamped on the die ring.
Check crimper calibration and re-calibrate if required.
Inadequate pump pressure. Check oil level in the pump. It should be 1-1/2 to 2 inches below the fill plug.
Replenish with ISO Viscosity Grade 46 hydraulic oil.
Inadequate lubrication of the dies and compression ring causing the pump to work harder than normal to
reach the required diameter. Use only the grease shipped with the machine or equivalent.
Inadequate pressure being generated by the pump. This is most likely if the crimper can crimp the
smaller size hoses and not the larger hoses. When correctly adjusted, the pump should generate approximately
10,000 psi.
Do Not adjust pump to produce in excess of 10,000 psi as damage to components or personal injury may
result.
No pressure being generated by the pump. There should be a definite change in pitch of the pump as it
cycles into high pressure mode and begins to “work” harder.
PROBLEM: CRIMP DIAMETER TOO SMALL
Incorrect setting of the Micro-Crimp Adjuster. Check crimp specifications.
( NOTE: All published machine settings are approximate. To correct for slight variances, the gauge settings
may be adjusted for the specific hose, fitting and size combination.)
Incorrect die being used (See die range under Crimp Diameter too Large)
Check crimp diameter and re-calibrate if necessary
PROBLEM: DIES STICKING IN COMPRESSION CONE
Inadequate lubrication of the compression cone and die surfaces. Use only the grease shipped with the
machine or equivalent.
