GENERAL
New-Line crimping machines are electrically operated hydraulic crimping
machines for hydraulic hose assemblies. The crimping machine comprises a
crimping head and a hydraulic unit mounted on the oil tank which serves as
machine frame. Normally delivered with a single electric motor. On request it
can be equipped with a 3 phase motor.
TRANSPORT
The packed machine is transported on a pallet, which is easy to move and lift
by a forklift truck. After unpacking, the machine can be lifted using a
hoisting belt. Size of package for P51-models: x = 102, y = 82, z = 113cm.
Size of package for other models: x = 77, y = 62, z = 81cm.
STORAGE
The manufacturer has protected the machine against the ma-
e chine against corrosion by using the Zerust method. The ma-
chined parts have been treated with Axxatec 77C protective agent. A Zerust
vapor capsule has been put into the electric
in box, and the machine has been packed into a bag made of
Zerust film. The protection is effective for months if the package is not
l opened. After opening it, the protection of the wrapping film
ceases. If the machine is not yet brought into use, it must be
– reprotected against corrosion. The machine is to be stored in
dry indoor conditions. Remove the protective agent according to the
instructions
w enclosed in the package.
MOUNTING
e The adjacent picture shows an appropriate way to lift the man chine after it
has been unpacked. It is recommended to mount
the machine on table. Before mounting, the table must be screwed to the floor
with four M12 wedge anchors. Boreholes in the floor: Ø 12mm, depth 55mm. When
the machine is mounted on the table, the four shoes under the machine are
removed. The table with assembly instructions is packed separately. The
crimper may be installed on some other table as well, provided it is sturdy
and broad enough or it has been fastened on the floor so that it cannot fall
over. Furthermore, there must be a hole in the table to enable emptying the
oil tank through the drain plug. S20 & S32 – models x = 558, y = 560.

WARNINGS
GENERAL
The machine is intended for professional use. It is to be operated only by a
trained operator who has understood the dangers involved in the operation.
Openings between the dies exceed 6mm, thus being large enough to let fingers
go between the dies and get crimped. It is, therefore, ABSOLUTELY necessary to
follow operating instructions and warnings indicated by the stickers on the
machine when changing dies and crimping fittings.

COMMISSIONING ine OIL FILL l Fill the oil tank to centre line of the
indicators in the dipstick with hydraulic oil like Shell Tellus T46 or –
equivalent. Volume of the tank is 32 litres.
It is recommended to pump the oil into the tank through a 20 filter, because
new oil in drums is not pure.
w OIL FILL
CAUTION! Check that the machine voltage (see type plate) is equal to your
supply voltage. For proper
e installation to local code, consult a licensed contractor. n Bring the
supply cable in through the hole in the side panel of the electric box. Secure
the cable with a
stress relief plug.
1-phase: Connect the phase and the neutral to the retrospective terminals in
the supply disconnecting device. Connect the earth connection to the ground
terminal on the fixing plate. Check the connection against the wiring diagram
enclosed in the spare parts list.
3-phase: Connect the phase conductors to the respective L1, L2 and L3
terminals in the supply disconnecting the device. Connect the earth connection
to the ground terminal on the fixing plate. Check the connection against the
wiring diagram enclosed in spare parts list.
Check that the motor rotation is parallel with the arrow on the tank close to
the motor. In case the motor rotates in wrong direction, two phase conductors
in the supply disconnecting device must be interchanged.
QUICK FIX-PACKAGE
Included with the machine, there is a Quick Fix-Package which has some basic
parts for that machine model.

SELECTING THE DIE SET
Use only original die sets in crimping machines. Refer to the fitting
manufacturer’s specifications for proper crimping diameter for the fitting.
Each die set has its own crimping range. Follow it to assure the roundest
possible crimping result. The minimum crimping diameter D is marked on each
die set. Example: with die set No 18506/10 the minimum crimping diameter is 10
mm.
line INSTALLING THE DIE SET – QUICK CHANGE MS (OPTION)
An optional Quick Change Tool Base enables storing die sets under the machine.
Die sets can be installed into the master dies with a quick change tool one
set at a time.
w · Before installing dies, make sure that the master dies are clean.
· STOP THE MOTOR PRIOR TO CLEANING DIES.
e · Insert the pins of the tool into the die set in the die table, turn the
tool clockwise and pull the whole set out (Image on next page).
n· Hold handle of the quick change tool as shown in Figures 1 and 2, and make
sure your hand will not get between the dies. · Mount the die set between
master dies (Fig. 2) and start closing the dies. · TO AVOID DAMAGING MASTER
DIES, MAKE SURE THAT ALL DIE SET PINS HIT IN THEIR
HOLES. · Close the master dies completely until the pins are locked in their
places (Fig 3). Remove the
tool. The dies are now ready for use (Fig 4). · Die set is removed from the
master dies in reverse order: close the dies, insert the tool into the
die set, open the master dies and place the set back in the die table.
8
QUICK CHANGE MS (OPTION)
· Start the motor and depress the retraction button until
maximum retraction is reached. Stop the motor.
CAUTION | THE MOTOR SHALL ALWAYS BE
STOPPED DURING INSTALLATION OF DIES.
· Prior to installing dies, clean the contact surfaces of
both the die set and master dies properly to avoid
damaging the surfaces.
· Pull the pull pin in the master die with the tool delivered
together with the machine (see figure).
· Insert the die with the retaining pin into the master die,
die number always towards you. Release the pull pin.
· After installing all the dies, make sure they are straight
and properly seated in the master dies.
SETTING THE CRIMPING DIAMETER MS
new-line The crimping diameter chart S32
EXAMPLE: Manufacturer has specified a crimping diameter of 20.6 mm for the
fitting. Select die set No 20-19 (min crimping diameter 19 mm) according to
the die chart. Turn the dial to position 1.60 (upper scale 1, lower 60). This
setting will give the crimping diameter 20.6 mm (19 + 1.6 mm)
The machine has been calibrated at the factory with 40 bar pressure. This
means that when you are crimping a fitting requiring 44 bar pressure, the
measuring scale of tte crimping diameter dial provides an accurracy of +/- 0.1
mm (possible elastic recover of the ffitting not
regarded).
PREVENTATIVE MAINTENANCE
· The following maintenance operations can be performed by the operator
according to the instructions below. However, electrical works and repairs
like changing seals or the pump must only be carried out by a qualified
specialist.
· PRIOR TO ANY SERVICING OPERATION, TURN THE SUPPLY DISCONNECTING DEVICE TO
POSITION `0′.
· BEFORE CHANGING THE MOTOR CIRCUIT BREAKER OR UNDERVOLTAGE TRIP, DISCONNECT
THE PLUG OR SUPPLY CABLE FROM THE MAINS!
· Open the dies to maximum retraction before servicing.

GREASING S20 & S32
· Lubricate the inner surface of the conical flanges daily with pressure-proof
grease like Molub Aloy OG-H or equivalent.
· Apply the grease to the conical surfaces at the front and back of the die
with small brush. · Lubricate often with a small amount of grease rather than
seldom with much grease. · Do not grease the piston rod.
e RE-CALIBRATING OF CRIMPING DIAMETER DIAL MS -CONTROL in NOTE: The crimping
diameter dial has been calibrated at the factory during test run.
- Re-calibrate the crimping diameter with ferrule
l (seamless steel tube) Ø 25 mm; wall 2 mm, by us-
ing the die set No 20-19 (S20) or the die set 32-19
– (S32) - Set the dial at 1.0, so that the crimping diameter
w will be 20 mm (see adjacent picture) and lock the dial.
Crimp the ferrule and measure the real diameter.
e 3) Remove the control dial (avoid turning the dial n shaft at the same time). - Open the dial lock and set the real diameter into it (diameter of ferrule)
relock it and reinstall. 5) Turn the dial to right diameter and crimp another
ferrule. Now the machine has been calibrated and the real diameter should be
the same as the diameter on the dial. If not, repeat from point 2 and be more
careful when handling the dial. 6) After the adjustment, the crimping result
should be the minimum nominal crimping diameter of each die set with the dial
at 0.0.

IMPROPER DIE WARNING
Improper die set may have the effect similar to the picture shown on the next
page. The die set protrudes outward and the rear part of the master die is off
the cone track. You can observe the phenomenon quite easy when crimping if
this happens. Please view these pictures carefully. When you encounter the
same issue, please stop crimping immediately. You need a proper die for your
fitting. This machine requires a balanced crimping. If you experience an
improper die – stop crimping immediately and change a die set or contact us
for a replacement die set.
POSSIBLE CAUSES
- The die diameter is not correct, you chose a smaller die (the difference
between the die diameter and coupler diameter shall be less than 10 mm). If
exceeding 10 mm before crimping, you must check the die sets and change to the
one closest. 2) The die set is too long compared to the length of the ferrule
needing to be crimped. This makes the crimping part too forward to be abel to
crimp evenly or balanced. This will cause the problems shown
e in the pictures on the next page. Normally this is casued by one piece fitting, as one piece fitting is very
short compared to the normal fittings. Our standard die set is designed to crimpe the most fittings, thus
in it is usually longer. But when you encounter these phenomena, please stop crimping and request prop-
er die sets from us. Please stop crimping when you experience these issues. If you proceed you will have serious conse-
l quences like but not limited to: breaking the jaw of the master die and damaging the front and back new- cone surface, which will eventually make the machine useless.
