Quick Cable Quick Crimp Pneumatic Crimper - Manual (Page 7)

The Quick Crimp Pneumatic Crimper is designed to work on a shop air supply of 90 psig. It
has a working range on shop air down to approximately 80 psig; line pressures below that will
not deliver satisfactory results. Variations in air pressure supply at your location may require
adjusting the auto-cycle setting of the Quick Crimp Pneumatic.
The air gauge on the Quick Crimp Pneumatic shows the air regulator setting when the
machine is idle. This may be different from the supply line pressure—the regulator is able to
increase pressure by restricting the input orifice size. When the machine is idle the regulator
should show a reading of 85 or more in most cases. The regulator pressure is easily adjusted
with the regulator knob shown in figure 2. Turn the knob clockwise (CW) to increase pressure
and counter-clockwise (CCW) to decrease pressure.
Each complete cycle of the Quick Crimp Pneumatic Crimper consists of pressurizing the
pneumatic cylinder to a predetermined set point, and then releasing the air pressure. As you
watch the gauge, it will drop immediately after you press the foot pedal as the pneumatic cylin-
der begins to fill, and then the pressure will increase to the final crimp pressure that it delivers
before the pressure falls again. The crimping pressure that you see should be 80 psi. This is
referred to as the Auto-Cycle setting.
If the Auto-Cycle setting is less than 80 psi, it should be adjusted higher by turning the ad-
justing screw clockwise. Make adjustments slowly, ¼ to ½ turn at a time, cycle the crimper and
note the readings.
In order for the Auto-Cycle to work, there must be a difference of at least 5 psi between the
idle air regulator setting and the Auto-Cycle setting. If the machine will not complete the
cycle—if it will pressurize the pneumatic cylinder to the tripping point where the air is released,
the difference is too small. Either raise the regulator setting or decrease the Auto-Cycle
setting.
If the machine chatters at the end of a crimp cycle, the Auto-Cycle setting is too low, so you
must either raise the Auto-Cycle setting or lower the regulator setting.
Note: The Quick Crimp Pneumatic will not
cycle if the protective guard is not lowered
in place. Raising the guard automatically
releases the air pressure, so if the machine
fails to cycle and you want to reset, lift the
guard and then replace it.
The pressure differential between the regula-
tor setting and the Auto-Cycle setting should
never be more than 20 psi, but must be
greater than 5 psi.
Quick Cable recommends testing crimp
quality periodically using a calibrated
pull-tester. Quick Cable can perform these
tests—contact our customer service depart-
ment for more information.
