HOSE PREPARATION
A new hose and end fittings (stem/ferrule) must be used when building a hose assembly. Re-using
any component will seriously affect performance and could result in serious injury or property damage
Two-Piece Couplings
1. Cut Hose to desired length.
2. Using Gates Crimp Data Manual
#35019 (Ind), 428-7365(Auto) select the
correct stem and ferrule. Or, log onto
www.gates.com/ecrimp for the latest crimp
information on line
3. Place the ferrule over end of hose. If
skiving is required, see instructions in
Gates Hand Skiver manual # 35019-W
4. Lubricate the first two or three serrations
on the stem with lightweight oil (SAE 10W)
5. Clamp the stem in vise on hex portion,
and push hose onto stem. Hose should be
flush against stem shoulder (See cutaway
drawing)
6. Push ferrule so it rests against hex of
stem. Hose and coupling are now ready for
crimping
MegaCrimp® Pre-Assembled
Couplings
1. Cut hose to desired length
2. Using Gates Crimp Data Manual
#35019(Ind), 428-7365 (Auto) select the
correct MegaCrimp® coupling. Or, log onto
www.gates.com/ecrimp for the latest crimp
information on-line.
3. Place a visible mark on the hose cover
at the insertion length shown in the crimp
data manual.
4. Insert coupling into the hose until the
mark lines up with the end of the coupling
ferrule.
5. Hose and coupling are now ready for
crimping.
See Hose Assembly Guide of the Gates
Crimp Data Manual #35019(Ind) and

SC32 CRIMPER CALIBRATION PROCEDURE
1. Install the “.733” die set to calibrate
the machine using an 8G Megacrimp®
coupling.
2. Set the Dial Vernier setting to
5.20. Rotating the dial clockwise will
increase the number and rotating it
counterclockwise will decrease the
number. When changing the setting,
always move to a higher number then
down to the desired setting
• Example: To change from 5.00 to
5.20, move the Dial Vernier up to 6.00
then down to 5.20.
3. Insert the coupling into the die set
approximately 1/8 inch below the top of
the die. (See Photo 1)
Photo 1
4. Push and hold the start/stop switch
until the pump stops.
5. Remove the coupling and measure
the crimp diameter which should measure
1.000 +/- .003 inches. See page 8 for
measuring crimp diameter.
6. If ferrule crimp diameter is not
acceptable adjust the Dial Vernier (See
Photo 2)
Photo 2
• To increase the crimp diameter, hold
the Dial Vernier barrel with a 5/16 inch
open end wrench and rotate the stem
out of the barrel with a 5/32 inch hex
key wrench.
• To decrease the crimp diameter, hold
the Dial Vernier barrel with a 5/16 inch
open end wrench and rotate the stem
into the barrel with a 5/32 inch hex key
wrench.
7. Repeat steps 2 through 5 to verify the
correct crimp setting.

OPERATING INSTRUCTIONS WITH PC707 DIES
1Note the tag attached to the pump motor
and make certain that the power source
matches the requirements specified on the
tag.
2Make certain that the base is clean.
Insert the standard Pressure Plate and
tighten the set screw through the hole in
the hand hazard decal with a 1/8 inch hex
key wrench.
3Orient the Pressure Plate as shown and
tighten the set screw to hold it securely
in place. Lubricate the Pressure Plate
with a high quality moly-disulfide grease .
Molykote “G” is recommended.
4Select the correct die set from the Gates
Crimp Manual #35019 (Ind) and 428-7635
(Auto) or log onto www.gates.com/ecrimp.
Lubricate the outer surfaces of the dies with
MolkKote “G”
5Position the Compression Ring loosely
over the die set and insert the hose and
fitting from the bottom of the crimper.
6Position the ferrule or MegaCrimp®
approximately 1/8 inch below the top of the
die fingers.
Important: Be sure the hex of a straight
stem or round portion of a bent ferrule
rests against the ferrule.
7Adjust the Dial Vernier to the setting
obtained from the Gates Manual for the
combination of hose and fitting being
crimped.
8Press and hold the pneumatic start/
stop switch until the motor shuts off and
the ram retracts.
9Always measure the finished crimp
diameter to be certain that it is within the
Gates specification.

7
OPERATING INSTRUCTIONS DOUBLE ANGLE DIES
SC32 DA Double Angle Dies
Double Angle dies effectively double the
force of the crimper thus larger fittings
can be crimped than would be possible
with conventional dies. The trade off
is that the diameter range that can be
crimped with a given die is more limited
than with a conventional die.
Use only the dies specified in the Gates
Crimp Specifications for a given combi-
nation of hose and fitting.
1Remove the standard Pressure Plate by
loosening the set screw holding it in place.
The set screw is located through the hole in
the Hand Hazard Decal. A 1/8 inch hex key
wrench is required.
2Install the Double Angle Base Ring
making certain that the bottom flange is
clean and free of debris and that the base
ring seats firmly and squarely in the bottom
flange.
3Select the correct Double Angle Die for
the hose and fitting combination being
crimped. Lubricate the I D of the Bottom
Base Ring and the top Compression Ring
with a high quality moly-disulfide grease .
Molykote “G” is recommended.
4Place the top Compression Ring
squarely on top of the Double Angle Die
set.
5Insert the Hose and fitting from the bottom
of the crimper.
Note: In order to avoid taper in the final
crimp, the fitting should be centered
vertically in the die set.
6Adjust the Dial Vernier to the setting
obtained from the Gates Manual. Note that
for Double Angle Dies settings greater
than 16 are above the zero due to the
special calibration factors for Double
Angle Dies.
7Install the Pusher on the ram if it has
been removed and press and hold the
pneumatic start/stop switch until the
motor shuts off and the ram retracts.
8Always measure the finished crimp
diameter to be certain that it is within the
Gates specification.

8
MEASURING CRIMP DIAMETER
To properly measure a crimp diameter:
DO NOT measure on top of
part number stamps
When using 21 and 22 Dies
1. Using Gates “21/22” dial calipers (Product
No 739-1320, 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).
3. Should actual crimp diameter not be
within recommended crimp tolerance, check
calibration of the machine and recalibrate.
If machine is properly calibrated, you may
need to make a slight adjustment to the Dial
Vernier Adjuster,
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 part
number stamps (See Photo 3)
2, Measure halfway down the crimped
portion of the ferrule (Sketch 2).
4. To obtain a smaller crimp diameter,
change the Vernier Adjuster to a smaller
number. To get a larger crimp diameter,
change the Vernier Adjuster to a larger
number. Changing the adjuster readout by
.05 will change the crimp diameter .001”.
Record the new setting on your crimp chart
for future reference.

TROUBLESHOOTING
PROBLEM: CRIMPER WILL NOT RUN AT ALL
• The white rocker switch is also a circuit breaker. Check to see that the circuit breaker has not
been tripped.
• Check the wall outlet. The crimper comes from the factory wired for either 115V AC or 220V
AC single phase circuit. Make certain that correct voltage and amperage is available. Use
of extension cords or outlets with inadequate power can damage the motor . Do not run the
crimper from a portable power source.
• Check the stop switch mounted to the switch bracket under the Dial Vernier. This is a normally
closed switch and if it does not close the crimper will not operate.
CAUTION: Do not operate the crimper with this switch jumpered as the pump will not shut off
and the brackets can be damaged.
• Check the pneumatically actuated switch in the electrical box mounted on the motor. This
switch controls power to the motor and is actuated with air pressure from the bulb on the end of
the hose going into the box.
PROBLEM: CRIMP DIAMETER TOO LARGE
• Check crimper calibration and re-calibrate if required.
• Incorrect die being used.
• Incorrect setting of the Dial Vernier Adjuster. Check hose crimp specifications.
• Inadequate pump pressure. Check oil level in the pump. It should be 1-1/2 to 2 inches below
the fill plug. Replenish with ISO Viscosity Grade 46 hydraulic oil.
• Inadequate lubrication of the dies and die cone causing the pump to work harder than normal to
reach the required diameter.
• Inadequate pressure being generated by the pump. This is most likely if the crimper can crimp
the smaller size hoses and not the larger hoses. When correctly adjusted, the pump should
generate approximately 10,000 psi.
Do Not adjust pump to produce in excess of 10,000 psi as damage to components or personal
injury may result
• No pressure being generated by the pump. There should be a definite change in pitch of the
pump as it cycles into high pressure mode and begins to “work” harder.
PROBLEM: CRIMP DIAMETER TOO SMALL
• Check crimp diameter and re-calibrate if necessary.
• Incorrect die being used (See die range under Crimp Diameter Too Large).
• Incorrect setting of the Dial Vernier. Check hose crimp specifications.
PROBLEM: DIES STICKING IN COMPRESSION RING
• Inadequate lubrication of the die cone and die surfaces.

MAINTENANCE
This crimper requires minimal maintenance.
However, the following practices are
recommended 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
• Check the hydraulic oil level in the pump
reservoir after each 10 hours of operation.
• If the oil in the hydraulic reservoir is more
than 1 1/2 to 2 inches below the fill plug
add ISO Viscosity Grade 46 hydraulic oil
3. Change the oil
(Note) Frequency depends on the pump’s
general working conditions, severity of use
and overall cleanliness.
• For general shop conditions change the
oil every 300 hours.
• Drain the oil through the plug in the
bottom of the reservoir and refill with ISO
Viscosity 46 hydraulic oil to between 1 1/2
and 2 inches below the fill plug
4. Inspect Die Sets
• Periodically inspect the surfaces of dis
sets for debris (metal chips, dirt, etc.) or
damage.
• If debris is present, clean and lubricate
with Molykote “G” grease.
• Check screws holding fingers to
cage to make sure that they are tight.
Tighten if necessary.
5. Inspect hose assembly
• Inspect hose assembly connecting the
crimper and pump monthly (more often
with severe use)
• If hose has any signs of damage,
replace immediately. A damaged hose
may rupture and cause serious injury.
• If hydraulic oil is present on the hose
assembly, serious damage may exist.
replace hose assembly immediately.
