Crimping Procedures
WARNING: Maintain clear distance from all moving parts .
Crimping Procedure
Refer to the current Danfoss Crimp Specifications for com-
plete and detailed crimp specification information for each
hose and fitting style.
1. Retract the cylinder by pressing the RETRACT switch until
the cylinder is fully retracted. Select the proper die cage
from current Danfoss Crimp Specifications. Insert die cage
onto the pressure plate.
2. Press the proper PRESET button or key in a value to the
DISPLAY. (See page 5 for keypad operating instructions.)
3. Position the fitting in the crimp die set according to the
corresponding figure shown in Figure 5.
4. To crimp the fitting, press the CRIMP switch or footswitch.
The die cage will advance until the fitting is fully crimped
(Figures 5 & 6). It will then automatically begin to retract,
signifying that the crimp is complete. Release the crimp
switch or footswitch. The cylinder will automatically
retract and stop at the “full retract” position (or at the
programmable retract position, if it has been set).
Hint:
Retraction can be halted at any point by momentarily
pressing the RETRACT switch or footswitch.
5. Verify the correct crimp diameter.
Procedure for determining a target setting
Enter the number “500” into the DISPLAY, and start the
crimping process. If the dies crimp the fitting, measure the
crimp diameter and decrease the DISPLAY setting by the
same amount that you wish to decrease the crimp diam-
eter. If the dies don’t touch the fitting, lower the DISPLAY
setting by 050 to “450” and crimp the fitting again. If that
still isn’t enough, continue to reduce the DISPLAY setting
by 050 increments until the dies make contact with the
fitting. Then, measure the crimp diameter and decrease
the DISPLAY setting by the same amount that you wish to
decrease the crimp diameter.
Example: If a display setting of “250”produces a crimp
diameter of 1.004 inches, subtract the crimp specification
(0.990 inches) from the diameter that you measured (1.004-
0.990=0.014). Then, subtract “014” from the DISPLAY
setting (250-014=236), and change the DISPLAY to “236.”
Crimp the fitting again, and measure the crimp diameter. If
the crimp diameter is still too large, repeat this process.
Note: Record the setting for future reference.
