WARNING –SAFETY PRECAUTIONS
DO NOT OPERATE THIS EQUIPMENT UNTIL YOU READ AND FULLY
UNDERSTAND ALL INSTRUCTIONS CONTAINED WITHIN THIS MANUAL.
ALWAYS WEAR EYE PROTECTION.
CRIMPER CAN PRODUCE 60 TONS OF FORCE. KEEP HANDS AND FINGERS
AWAY FROM MOVING PARTS.
WARNING! REFERENCE KURT HYDRAULICS CRIMP SPECIFICATIONS WHEN
USING KURT HYDRAULICS HOSE AND COUPLING COMBINATIONS. DUE TO
THE ADJUSTABILITY OF THE CRIMPER, HOSE AND COUPLINGS OF OTHER
MANUFACTURERS MAY STILL BE CRIMPED WITH THIS MACHINE. KURT
HYDRAULICS RECOMMENDS CONTACTING THE HOSE AND FITTING
MANUFACTURER FOR PROPER SPECIFICATIONS IF USING HOSE AND
COUPLINGS NOT FROM KURT HYDRAULICS. KURT HYDRAULICS DISCLAIMS
ALL LIABILITY FOR ANY HOSE AND COUPLING ASSEMBLY THAT IS NOT
MADE ACCORDING TO KURT HYDRAULICS RECOMMENDATIONS. CONSULT
YOUR LOCAL KURT HYDRAULICS REPRESENTATIVE OR DISTRIBUTOR IF
YOU HAVE ANY QUESTIONS.

INSTALLATION
Unpack the crimper and verify you have received the following items:
KH-60 Crimper
Reservoir Vent
Ram Pusher
Bent Tube Pusher Donut
Operators Manual
Moly Grade Anti-Seize 3 oz. Tube
Follow these steps before using the crimper for the first time:
1. Locate a sturdy bench or worktable at a suitable height for your needs that’s in a well-lighted
area and within 7 feet of a 110 Volt AC outlet.
2. Lift the crimper onto the located worktable. Due to the weight of the crimper, Kurt Hydraulics
recommends lifting the crimper by mechanical means at the top of the single handle. When
lifted by this handle, the crimper will be balanced. Place the front edge of the sheet metal
crimper base flush to the front of the worktable. The crimper is balanced in this position but
Kurt Hydraulics recommends using the four (4) mounting holes provide in the crimper base to
securely fasten to the worktable.
3. Plug-in power cord to a grounded 110 Volt AC outlet. The use of extension cords is not
recommended.
4. Remove the threaded shipping plug and replaced with the supplied vent.

HOSE PREPARATION
1. Kurt Hydraulics recommends that all KH60 crimper users familiarize themselves with all
warning statements, SAE J1273 standards, the technical guide in the Kurt Hydraulics Catalog,
and this Operator’s Manual.
2. Select the hose and coupling assembly.
3. Reference the latest Kurt Hydraulics crimp specification which can be found at
www.kurthydraulics.com, by contacting technical support at 1-866-257-7995, or sending a
4. Determine hose cut length by subtracting the cut-off factor for each coupling from the overall
length of the assembly. For these cut-off factors, reference the Kurt Hydraulics Catalog.
5. Cut the hose square and to the proper length with a suitable piece of equipment.
6. Mark insertion length on hose (reference figure above). Insert hose until it bottoms in
coupling.
CRIMPING
Once the hose and coupling are prepared, you are ready to crimp with the KH60 crimper.
Insure that you have the following:
Verify all components are available.
Properly prepared the hose and coupling.
Insure the interior of the hose is free of cuttings, dirt or other debris.
Obtain the Kurt Hydraulics crimp specifications.
1. Consult the Kurt Hydraulics crimp specification for the KH60 to determine the proper die set
for the chosen hose and coupling combination.
2. Lubricate the cone base and segments for the die set with the supplied anti-seize or equivalent
high pressure molybdenum grease. Re-apply grease regularly, especially when wearing
surfaces on cone base and fingers appear shiny. Kurt Hydraulics recommends applying more
grease at least every 10 crimps, or after periods of non-use.
CAUTION: Failure to lubricate die sets and the cone base regularly will cause damage to the die
set and could permanently damage the crimper.
3. Place the die set in the cone base. Verify that the dies
are properly aligned and that the die holders do not
overlap. Kurt Hydraulics recommends placing the
seam between the two die holders in front of the
crimper in view of the operator.

4. Insert the hose and coupling into the die set as
illustrated. Position the coupling to the proper depth
according to the following guideline:
Coupling with crimp location markings: Several
Kurt Hydraulics couplings are manufactured with a
knurl mark on the circumference of the ferrule.
Looking down from the die set, line up the middle
of the knurl with the top edge of the die set.
Coupling without crimp location markings:
Refer to the Kurt Hydraulics crimp specification for die position.
5. Manually place the pusher donut on top of the die
set with the clearance slot facing forward to the
operator. Be sure the top rings of the die set are
evenly contained inside the bottom of the pusher
donut.
6. Seat the die set in the cone base by firmly
pushing down on the pusher donut. Check the
alignment of the die set to make sure the die
holders are level and are not overlapping.
7. Slide the ram pusher onto the retainer disk at the
end of the ram.
8. Select the proper micrometer setting from the
Kurt Hydraulics crimp specification and twist the
top of the micrometer until that number appears on the micrometer barrel.
9. Depress and hold the foot switch.
10. Ram pusher will travel downward and engage pusher donut until the micrometer foot contacts
the limit switch.
11. Release the foot switch once the micrometer contacted the limit switch and the pump has shut
off.
12. Ram pusher returns to its fully retracted up position.
If multiple crimps are being made with the same
fitting, the retraction stop can be released and
tightened again while ram is extended. This will
limit the amount of retraction and advancement time
of the ram for the next crimp.
13. When the crimp cycle is finished and the ram pusher has retracted, manually remove the pusher
donut and pull the coupling out of the die set. The ram pusher can also be removed as
necessary depending on the size of the fitting being crimped. Using dial calipers or a
micrometer, measure the crimp diameter on the mid-point of the flat surface and of the crimped
coupling where die faces have met the coupling. Take four (4) measurements around the
coupling and average the measurements. Refer to the Kurt Hydraulics crimp specification to
confirm crimp diameter is in tolerance.

CALIBRATION CHECK
1. Brand new crimpers are shipped calibrated, but a calibration check is recommended prior to
using the crimper for the first time.
2. Lubricate all contact surfaces, place any die set, and the pusher donut in the crimper. No hose
and fitting are required for an initial calibration check.
CAUTION: Failure to lubricate die sets and the cone base regularly will cause damage to the
die set and could permanently damage the crimper.
3. Slide the Pusher onto the retaining disc on the hydraulic ram.
4. Set the micrometer at “95”.
5. Press and hold down the foot pedal. For the portable unit operate the power unit according to
manufacturer’s instructions.
6. When the ram extends it should engage the pusher donut causing the dies to completely close
and the pump to start building pressure for approximately 1 second before shutting off, the
crimper is correctly calibrated.
7. If the time to shut off is not approximately 1 second after the die completely closes or the die
does not completely close, the micrometer must be adjusted.
8. For the KH-60-P Series: If the line is just visible as shown in the illustration after the dies are
completely closed and pressure has built up in the hydraulic cylinder the crimper is correctly
calibrated.
The KH60 crimper is factory calibrated prior to shipment.
However, due to machining tolerance on metal surfaces of the
die sets and cone base, as well as normal wear, recalibration
should be performed when the crimper consistently crimps
hose and coupling assemblies outside of the Kurt Hydraulics
crimp diameter tolerance.
