ET1280 Crimp Machine Set Up and Operating Manual E-EQCR-TM003-E September 2005
Establishing Crimp
Settings
The adjustment knob at the
top of the machine deter-
mines the crimp diameter
for each combination of
hose, fitting, and die cage.
The numbers on the dial and
barrel of the machine are for
selecting target settings and
not crimp diameters.
Settings between 000 and
400 can be achieved with
this crimp machine. Consult
the target setting chart for
the ET1280 crimp machine
for the initial setting.
There are 25 marks on the
dial (0-24), and 16 marks on
the barrel (025-400 by 025
increments). The top of the
barrel corresponds to a 000
setting. When the adjust-
ment knob is rotated to the
top most position on the
crimper, and the “0” mark is
located as shown in Figure
2, the machine setting is
000. Each complete down-
ward rotation of the adjust-
ment knob increases the
target setting by 025; each
mark around the dial corre-
sponds to a 001 change in
target setting. For example,
to achieve a target setting of
050, the adjustment knob is
rotated until the top of it
corresponds to the 050
mark on the barrel, and the
0 mark on the dial is lined
up with the center, vertical
mark on the barrel (see
Figure 3). One more full
downward rotation of the
dial would result in a target
setting of 075. If the
desired target setting is 065,
the dial would instead be
rotated downward 15
“marks” on the dial, or
approximately 2/3 of a turn,
past the 050 target setting.
Crimping Procedures
Refer to the current Crimp
Specifications Manual on the
Eaton website for complete
and detailed crimp specifica-
tion information for each
hose and fitting style.
1. Select and load the proper
die cage according to the cur-
rent Crimp Specifications
Manual on the Eaton website.
2. Rotate the adjustment
knob/barrel indicator to the
proper setting (see Example).
3. Position the fitting to
the proper crimping position
within the die cage
according to the Crimp
Specifications Manual on
the Eaton website.
4. To crimp the fitting in
an 110V Power Unit model,
press and hold the crimp
switch in the upward position.
5. The crimp switch may be
toggled up and down as
required to reposition the fit-
ting. To crimp the fitting in a
Hand Pump, Air/Hydraulic
Pump or 12V DC Pump
model, activate the hydraulic
power source according to
the respective pump manual.
Note:
The use of a 10,000
psi hydraulic power source
is required to operate the
ET1280 crimp machine. If
lower rated power units are
utilized, improper crimping
may result.
5. When the fitting is fully
crimped, all movement in the
machine will stop, and the
black guard around the piston
(pinch point hat) will move up
and completely cover the red
indicator ring located on the
adjustment knob.
6. Release the hydraulic
pressure and remove the
crimped hose assembly.
For the 110V Power Unit
model, this is accomplished
by pressing and holding the
crimp switch in the down-
ward position until the
machine is completely
retracted. For the Hand
Pump, Air/Hydraulic Pump or
12V DC Pump model, refer
to the manual provided with
the respected pump for
pressure release.
7. Verify that the correct
crimp diameter and crimp
length is achieved.
Crimping Procedures
WARNING:
Maintain clear distance from all moving parts.
Figure 4
For proper crimping procedure,
refer to the Crimp Specification
Manual on the Eaton website.
Example:
Position the adjustment knob at
a setting of 300. Activate the
hydraulic pump and attempt a
crimp. If the dies crimp the fit-
ting, measure the crimp diame-
ter and decrease the machine
setting (rotate the adjustment
knob upward) by the same
amount in thousandths of an
inch that you wish to decrease
the crimp diameter (a smaller
target setting number means a
smaller crimp diameter. If the
dies do not crimp the fitting,
decrease the machine setting
by 050 increments until the dies
do touch the fitting and the
resultant crimp diameter can
be measured.
For a target crimp diameter of
0.990 inches and a machine
setting of 250 produces a crimp
diameter of 1.124 inches, sub-
tract the target crimp diameter
(0.990 inches) from the diame-
ter you measured (1.124 - 0.990
= 0.134). Subtract 134 from the
machine setting (250-134=116)
and change the machine set-
ting to 116. Crimp the fitting
again and measure the crimp
diameter. If the crimp diameter
is too large, repeat this
process. If the crimp diameter
is too small, repeat the process
but instead add the difference
to the machine setting.
