Ⅱ、Introduction of products
BNT68 hose crimpers is one of our new products, it is a heavy
type. Our technicians already have mature technology for many
years, we add the self–filling oil cup on the machine head, in which
you can fill oil automatically. we also add oil grooves on the die
bases, very easy for lubrication and cleaning. This machine has
3. 3
large mouth, low gravity, convenient operation, and the swaging
force grow doubled because of mechanical convert
design,operation will be easy. And the machine oil system can be
cooled circularly,so it supports long time working and large quantity
working. We will do our best to make one satisfactory brand!

V、Instructions for use and maintenance
I、Operation
1. Store the machine:When you open the package, please put
the machine in the ventilation and dry house whose temperature is
above 10℃.
6. 6
2. Add the hydraulic operating fluid: You can add the hydraulic
operating fluid slowly by the empty filter beside the motor. ( Please
see the technical data to get the hydraulic oil type). Please look the
scale of oil, when you added the oil to the scale of 3 / 4, please
stop.
3. Connect the electrical wire: The voltage of these series
machines is 380V*50HZ. Meanwhile, these machines need three
phase (four wires).The electric controlling part is behind of the
operation part. And the customers need a professional electrician
to wiring.
4. The direction of turning about plunger pump: please open
the switch when you ensure the electricity goes smoothly. Then
press the “ON” start button,the motor will start to run. At this time,
look the direction of turning . If the direction is wrong, the machine
will not operate. The right way: the inverted hour is right direction.
The way of adjusting the direction: turn off the power, change the
two live wires.
5.Systematic pressure：hydraulic pressure adjusted right when
the machine goes out from the factory. Don’t adjust to avoid the
machine broken.
7. 7
6.Exclude the air: The system has air when the machine operate
at first time. Therefore, the die base will tremble. Don’t worry, it’s
normal. Please open the air bleed, then the air goes out and the
trembling disappear.
7. Choose the die: The customers can choose the die according
to the hose. The surface of die has the dimension of the hose.
8. Install the die: The right way to install the dies : Screw off the
bolts, and install the dies as per the number. Then, screw down the
bolts.
9. Lubricate the die base: At the beginning of crimping, add the
lithium grease to the head of die base so that the working
surface(cone surface) is smooth.The more oil grease will flow out
from the mouth under the machine head.
10. Operate the hose crimper: when you finished that the above
mentioned, cancel the emergency stop button, the machine start
to run. First, press the start button, Second, push the toggle switch
to inching position, Then press tighten button so that the hose can
8. 8
be crimped. At this time, adjust the precise locator to get your
crimping size. Press the loosen button to open, this process is over.
Then push the toggle switch to automatic position. Press the
tighten button or pedal switch, the machine will crimp one process.
II、Maintenance
1. You should often add the working surface and die base surface,
and keep them clean.
2. Please keep the machine head clean in order to avoid
something into the cylinder and the die base
3. Make sure the hydraulic liquid is clean, it will be affecting its life.
4. Clean oil filter and internal tank regularly. Clean them twice in a
year.
5. Please check the flanges and fix the bolts regularly. If they are
loose, please screw down.

Ⅷ、Troubleshooting
Fault Reason The way of avoiding
The hydro
cylinder don't
work after the
machine
operated
1There is no oil in tank.
1. Add the enough
hydraulic oil in the tank.
2. The direction of motor is
diffident with the pump’s
direction.
2. Adjust the direction of
motor.
3. The hand-wheel of high
pressure relief valve is
loose
3. Adjust the hand-wheel.
4. The new machine
couldn't operate at first.
4. Open the air valve to
deflate.
The system
couldn't
indicate the
pressure
1. The hydraulic oil pump is
damaged.
1.Change a new oil pump
2. The manometer is
blockage or broken.
2.Clean the flow line of
manometer or change a
manometer
3. The hand-wheel of relief
valve is loose.
3. Adjust the hand-wheel.
Stick-slip
phenomenon
1. The NO. of oil is wrong.
1.Change the oil, and open
the air valve to deflate
2.The level of oil is too low
and the air came in.
2. Add the hydraulic oil,
and open the air valve to
deflation.
3. Oil filter is clog. 3. Clean the oil filter.
The noise of
system is too
loud
1. The pump absorb
unknown thing.
1.Clean the pump
2. The oil in the tank is
shortage.
2. Add the hydraulic oil to
the required position.
12. 12
3. The pressure of low
pressure relief valve is too
low. The
Hydraulic operated check
valve is closed.
3.Adjust the low pressure
relief valve to required
value.（5Mpa)
Couldn't change
the direction
when crimping
1. The electromagnet of
solenoid valve is broken.
1. Change a solenoid
valve.
2. The pressure relief valve
is locked. The
hydraulic operated check
valve is opening.
2.Clean the pressure relief
valve
3. The hydraulic operated
check valve is locked.
3. Clean. the hydraulic
operated check valve
4.Front (behind) approach
switch is damaged
4.Change the front
(behind) approach switch
The running of
die is no
synchronous
1. The oil in the dies flanges
and piston is shortage.
1. Add the oil to those
accessories. .Make the
machine runs without
crimping the hose.
2. The spring breaks off. 2. Change a spring.
3. The hydraulic oil is too
dense.
3. Change the hydraulic oil.
4. Oil filter is clog 4. Clean the oil filter.
The flange has
uncommon
sound when
crimping
1. The flange’s surface is
broken.
1. Take off the flange and
rub the broken the surface
of flange and die base.
The switch is
closed
automatic.
1. The electric power
source is wrong.
1. Check the electric power
source
