Note: Do Not operate 115V crimper with a 230V pump. Digital readout will be damaged. See page 11
for additional instructions.
Do not use 720 or 739 die set with notched die cone. May cause damage to die cone.
CAUTION:

1. Remove crimper, back-up ring, two die
cones, die magnet, hose assembly, mounting
bracket with bolt, jar of Molykote “G” grease,
operating manual, crimp data book and crimp
decals from shipping carton. Locate serial
number on base plate in front of left post and
record on Page 1. Be sure to fill out the
crimper registration card. (By completing the
card and returning it to Gates, you will receive
crimp data updates and full warranty cover-
age.) Remove pump, breather cap and operat-
ing manual from its shipping carton.
2. Mount crimper so it overhangs a work-
bench (as shown in Photo 1). The back of the
cutout (in the base plate) should be in line
with front of bench. The bench should be 37”
to 42” high, stable and of sturdy construction.
3. Drill three 3/8” diameter holes as shown
in Illustration 1. Connect the mounting bracket
to top rear of crimper and to the hole farthest
from edge of workbench. Further secure
crimper to workbench using the two
remaining holes.
4. When crimper is secured to the work-
bench, connect hose assembly between
crimper and pump.
5.Connect receptacle on short cord of pump
to plug on cord of switch box of the crimper.
If plug and receptacle do not match, do
not try to connect. Differences in the plug
and receptacle indicate the pump and crimper
have different voltages and should not be
operated.
6. Remove plug from top of pump reservoir
and replace with breather cap provided. Check
that hydraulic oil is within 1/2” of bottom of
plug opening. If needed, add Dextron II ATF or
equivalent to reservoir.
7. Verify that switch on pump electrical box is
in “OFF” position. Connect pump power cord
to a 15 amp (minimum) rated electrical circuit.
8. Move switch on pump electrical box to
“ON” position. This will provide power to the
pump and crimper.
9. Turn knob on top of crimper switch box to
get a setting of 2.00 on the readout. Cycle
crimper at least 5 times to bleed air from
cylinder and hydraulic system.

1. Before initiating calibration procedure,
make sure crimper has been cycled five times.
To cycle, dial in a setting of 2.00 and run
crimper down to shutoff with no die set
loaded.
2. Install the “733” die set to calibrate the
machine using an 8G MegaCrimp®coupling.
3. Set the digital readout setting to 5.20.
(Rotating the knob on top of switch box clock-
wise will increase the number; counterclock-
wise will decrease the number. When chang-
ing the setting, always move to a higher num-
ber then down to the desired setting.
Example: To change from 5.00 to 5.20, move
dial up to 6.00 then down to 5.20.) The
readout figures may jump a number; i.e. 5.20
to 5.19 or 5.21. This will not affect the crimp OD.
4. Insert the coupling into the die set
approximately 1/8” below top of die. (See
Photo 1.)
5. Slide the die cone assembly under the
ram until it stops against back locating pins
and push the crimp button and hold. Release
the button immediately when the pump stops.
6. Remover coupling and measure crimp diame-
ter, which should measure 1.000” ± .003”. (See
Page 9 for Measuring Crimp Diameter.)
7. If ferrule crimp diameter is not acceptable,
adjust actuator rod. (See Photo 2.)
a. To increase crimp diameter – Hold the
1-1/16” actuator rod while loosening the
3/4” lock nut. Rotate the actuator rod clock-
wise (one full turn of the actuator rod will
change crimp diameter approximately
0.024”). Then tighten the lock nut down.
b. To decrease crimp diameter – Hold the
1-1/16” actuator rod while loosening the
3/4” lock nut. Rotate the actuator rod
counter clockwise (one full turn of the actu-
ator rod will change crimp diameter approxi-
mately 0.024”). Then tighten the lock nut
down.
8. Repeat steps 3 through 7 to verify correct
crimp diameter.

When using 21 and 22 Dies
1.Using Gates “21/22” dial calipers (Product No.
7369-1320, Part No. 78217) measure halfway
between ridges (Fig. 1). To be sure crimp diameter
is being properly measured, mark a crimp flat.
Beginning with that flat, count 9 flats to get the
diameter. Be sure caliper blades DO NOT touch
ridges. (See Photo 3.)
2.Measure halfway between the ends of crimped
portion of the ferrule (Fig. 2).
When NOT using 21 and 22 Dies
1.Using Gates dial calipers (Product No. 7369-
0320, Part No. 78215) which are notched to clear
ridges, measure halfway between ridges (Sketch 1).
Be sure caliper fingers DO NOT touch ridges or

This crimper requires minimal maintenance.
However, the following practices are recom-
mended to ensure maximum reliability
and service.
1. Lubricate.
Using a small brush and Molykote “G”
grease, apply a light coat to the inside
surface of the die cone whenever it
becomes shiny.
2. Check oil level.
a. Check the hydraulic oil level in the
pump reservoir after each 10 hours of
use (see pump operation manual for
instructions).
b. If the oil is more than 1/2” below the
top, add Dextron II ATF or equivalent
until within 1/2” of the top of the
reservoir.
3. Change the oil.
(NOTE: Frequency depends on the
pump’s general working conditions,
severity of use and overall cleanliness.)
a. For general shop conditions, change
oil every 300 hours.
b. Drain, clean and refill the reservoir per
pump operating instructions with
Dextron II ATF or equivalent to within
1/2” of the top of the reservoir.
4. Inspect die sets.
a. Periodically inspect the surfaces of die
sets for debris (metal chips, dirt, etc.)
or damage.
b. If debris is present, clean and lightly
lubricate. If damaged, replacement is
required (see parts list for ordering
information).
c. Check screws holding fingers to cage
to make sure they are tight. Tighten if
necessary.
5. Inspect hose assembly.
a. Inspect hose assembly connecting the
crimper and pump monthly (more
often with severe use).
b. If hose has any signs of damage,
replace immediately. A damaged hose
may rupture and cause serious injury.
c. If hydraulic oil is present on the hose
assembly, serious damage may exist.
Replace hose assembly immediately.
Maintenance

11
The standard PC 707 crimper (P/N
7480-0043/77700) requires a 115V,
15A power source. It is possible to oper-
ate the crimper with a 230V, 15A power
source. However, a 230V wiring harness
must be purchased and the pump must
be rewired to use the PC 707 as a 230V
machine. If the crimper is not rewired
when operated at 230V, the LED digital
readout will be damaged. Other
problems may also occur if the PC 707 is
not operated using the proper power
source.
Instructions
1. Purchase a new, 230V wiring har-
ness (Prod. No.: 7482-0498 / Part
No.: 78748).
2. Unplug the pump from the power
source.
3. Remove the shroud from the PC
707 by removing the two allen
screws on the front of the shroud.
4. Replace the old wiring harness
between the digital readout meter
and the switchbox with the new,
230V wiring harness.
5. Place the shroud on the crimper.
6. Unplug the pump from the crimper
switchbox.
7. Rewire the pump for 230V. Note: A
230V pump can be purchased
(Prod. No.: 7481-0028 /
Part No.: 77811).
Rewiring the Pump
A. Unplug the pump from the wall
outlet.
B. Remove the coverplate on the
end of the motor control box and,
per the instructions on back of
coverplate, change the motor
leads to the 230V configuration.
C. Re-install the coverplate on the
motor control box.
D. Install a new, 230V, 15A male
plug on the power cord.
E. Check the plug types for the con-
nectors (one from the pump and
one from the crimper) between
the pump and the switch box.
Both plugs should be rated for at
least 230V and 15A to be used
with a 230V PC 707. If these
plugs are not rated to handle
230V and 15A, then replace both
plugs with nema L6-15 plugs.
After all the re-wiring is completed and
the plug and wire types checked (and
changed, if necessary), re-connect the
pump to the pump source and the
crimper.

All equipment is tested for proper performance before it is shipped from the factory. However, if you should
experience any difficulties, we recommend you check the guide below to help restore equipment to proper
operating standards before contacting Gates customer service.
Problem Solution
Crimper will not come up to pressure. ●Check the oil level in pump.
●Check operation of pump relief valve.(See pump operation manual.)
Crimping leaves a “bell” or “tail” on ferrule. ●Check location of ferrule in die fingers before crimping.
Crimping gives wrong crimp diameter. ●Check for proper die set.
●Check for proper hose/ferrule/stem combination.
●Check for proper digital readout setting.
●Check calibration of crimper.
●Change digital readout setting until an acceptable crimp diameter
is obtained. (See page 9) Record new setting for future use.
NOTE: Published settings are only approximate values. You need
to adjust your setting so that thecorrect crimp diameter is achieved.
Pump will not activate crimper. ●Check crimp switch on switchbox.
●Check electrical connections between pump and crimper and
between pump and wall outlet.
Crimping unit is off center under the ram. ●Make certain die backup ring is completely back against both rear
locating pins.
