9. Calibrate.
• Before crimping a hose assembly,
check calibration.
Calibration is the proper relationship between
a setting and the crimp diameter. It should be
checked at least monthly, possibly weekly or
daily, if crimper has been used heavily or
abused.
• Place the MC33 die set into the
die cone and install pressure plate.
• Turn the knob to a setting of 245.
Note: Rotating the knob on front of switch box clockwise will
increase the number; counterclockwise will decrease the num-
ber. When changing the setting, always move to a highter
number then down to the desired setting. (Example: To change
from 200 to 245, move dial up to 300 then down to 245.)
• Insert an 8G MegaCrimp®coupling into the
die set.
• Complete the crimp.
• Remove the coupling and measure the crimp
diameter, which should measure 1.000"
±.003". To properly measure crimp diameter,
refer to page 13.
• If the crimp diameter is within this range, no
adjustment is necessary.
• If the crimp diameter is not within this range,
the crimper must be calibrated.
• To get a smaller crimp diameter,
change the setting to a smaller number.
• To get a larger crimp diameter,
change the setting to a larger number.
• For every .001" change in crimp diameter,
change the setting by 002. For example, to
increase the crimp diameter by .002", increase
your setting from 245 to 247.
• Turn the knob to this new setting
and crimp a new coupling.
• After the correct diameter is achieved, pull the
plastic cap from the knob.
• Loosen the two (2) set screws in the brass knob
1/4 to 1/2 turn using a .05” Allen wrench.
• Turn the brass knob either clockwise or coun-
terclockwise to get the setting back to 245.
• Tighten the set screws and replace
the plastic cap.
• Crimper is now calibrated.
