3) Use and maintenance of hydraulic crimper
a. Avoid operation of hydraulic crimper at overload. Before
use, retract the piston completely, and counterclockwise
rotate the handwheel of the pressure relief valve so that
the crimping clip of hydraulic crimper can go back to the
fixed clip seat.
b. Counterclockwise rotate the fixed clip seat of the hydrau
-
lic crimper so that it leaves the cylinder bottom, remove
the movable pin connected to the key chain, and replace
the crimping module group matching with the hose.
c. Select the copper or aluminium joint matching with the
hose, insert the hose completely, and check the assembly
in place.
d. Install the above hose joint in the clip seat (i.e. mouth of
tongs), fold the movable clip seat to the fixed clip seat
so that the pin holes of two clip seats can coincide, and
completely insert the movable pin connected to the key
chain.
e. Clockwise rotate the fixed clip seat of the hydraulic crim
-
per so that it presses close to the cylinder bottom.
f. Re-check if the piston completely returns, counterclockwi
-
se rotate the handwheel of the pressure relief valve until
the piston completely returns, and clockwise rotate the
handwheel of the pressure relief valve so that the pressu
-
re relief valve is completely closed (firmly tightened).
g. Slightly press the handle so that the crimping clip is slow
-
ly close to the hose joint, and adjust the position of the
hose joint in the mouth of tongs simultaneously. When it
reaches the designed position, the crimping work begins.
h. During crimping, observe the joint change at any time to
ensure crimping quality and aesthetic appearance.
i. At the end of crimping, counterclockwise rotate the hand
-
wheel of the pressure relief valve slowly, so the piston will
rapidly return under the action of its spring force. Remove
the movable pin connected to the key chain, open the
mouth of tongs, and take out the crimped hose joint.
j. Perform crimping of the next joint or clean and store the
tools in a tool kit.

CAUTION ! Please keep the tools out of reach of children.
The us of the hydraulic tools by untrained person maybe
leads to the damage to the tools or personal injury.
CAUTION ! Do not increase the arm strength by expanding
the handle, or the tools will be permanently damaged.
CAUTION ! If the hose and joint are not in their places, the
clip seat is not close to the cylinder bottom, or a module
group does not match the hose joint, etc., it is impossible
to start the piston handle, or the tools will be permanently
damaged. In addition, keep no hand at any clipping point
during use of the tools.
Note: Use the correct model dimension, or leak or crimping fault may occur!

4) Equipment Maintenance
The equipment can be maintained by professional techni
-
cians using only the original parts in order to ensure the
equipment safety.
1.3 Important Instructions
Keep no hand or limb at the work area of hydraulic crimper.If
serious damage to the equipment leads to a large leakage or
cylinder burst, damage to piston and mouth of tongs, please
stop work immediately. Unauthorized maintenance may lead
to serious personal injury.
Replace the damaged parts only with original parts from our
company.
37-10291 hydraulic crimper can be used only by the trained
technicians for hose crimping.
The joint must match with the hose.
A defective joint must be cut before a new part is used for
re-crimping.
On completion of crimping , each joint must undergo pressu
-
re test in order to meet the process requirement.
