1. General
1.1 Usage:
The TW-10/16A/B/C series Rocker Hydraulic Pressure Cutting Machine is qualitatively
designed and manufactured based on more than ten years of experiences in production of
cutting machine and combined with the loud noise and poor safety properties of
small-tonnage mechanical cutting machine. It is a substitute for small-tonnage mechanical
cutting machine.
This cutting machine is mainly used in different industries to cut various soft materials, e.g.
leather, plastic, canvas, nylon, cardboard, etc., with knife die.
1.2 Characteristics:
1.) The cutting forces are 100KN and 160KN. The rocker arm width is 330mm.
2.) This machine is equipped with automatic lubricant system which can lessen wearing and
prolong the service life.
3.) The electronic delay circuit is adopted to control the low limit position of stroke, providing
higher precision and cutting quality. The hand wheel can be used adjust the height of
working table of rocker arm distance, featuring more simple, reliable and convenient.
4.) Main key parts: both the main post and the piston of oil cylinder adopt high quality steel.
5.) The inertia of flywheel can realize instantaneous cutting with low energy consumption.
6.) Type A adopts gear pump, and Type B adopts vane pump. Type C is made in Italian, with
selectable controls of pressure and time.

3.The installation of machine
3.1 Tie steel rope on rocker arm (note: close to arm post, no slippage). Transport this
machine to installation site with lifting equipment. During lifting, the original wood pad on
machine can not be removed. It shall be pressed on the workbench by rocker arm to prevent
said rocker arm from swinging flexibly, which can ensure no damage in components such as
hand wheel, handle, electrical apparatus, etc.
3.2 Clean relevant components with cleaning oil, especially the bright bared parts on main
post, and then apply lubricant. Disassemble the plastic backing plate on workbench and
calibrate the level in the vertical and transversal directions on the workbench surface with the
level bar.
It’s better to use forklift to shovel the bottom surface.
3.3 Disassemble the left-rear cover plate and add 45L of 46# antiwear hydraulic oil in oil tank.
Note that the oil shall not contact with the flywheel.
3.4 Connect the power supply of machine and make reliable grounding as per the electrical
principle and requirement. The power indicator will be on.
3.5 Press the ON button of motor to observe whether the rotation direction of the flywheel is
in accordance with the clockwise direction. Carry out test punching for several times with
empty load after idling for two minutes.
3.6 Press the OFF button of motor, the power indictor will be off, and the machine stops.
4.The function and debugging of machine control element
4.1 Set the delay timer in the minimum position.
4.2 Place the materials need cutting on the workbench.
4.3 Place the knife die on materials need cutting.
4.4 Move the rocker arm at the upright top position of the knife die to align rocker arm with
the centre line of knife die as possible.
4.5 Rotate the upper hand wheel. Lower the rocker arm along clockwise direction and lift it
along clockwise direction and lift it along anticlockwise direction, keeping a distance about
5~10mm between the bottom surface of rocker arm and the upper back of knife die.
4.6 Press the startup button (ON) of motor and push down the descending button of rocker
arm with hands. Note that those two buttons must be pressed synchronously. If the cutting
depth of knife die on backing plate is too large, adjust the knob of timer on the rocker arm to
a smaller value. Adjust this knob in accordance with above condition until the knife die is be
pushed into the backing plate slightly.

5. The operation order of machine
5.1 Place the materials need cutting on the plastic backing plate of the workbench.
5.2 Place the knife die on the position of the materials need cutting.
5.3 Move the rocker arm at the upright top position of the knife die.
5.4 Press the descending button of the rocker arm with hands.
5.5 Release the descending button of rocker arm to move rocker arm. Remove the required
cutting materials. One cycle of operation is completed.
5.6 Place the knife die on the materials need cutting again to enter next cutting operation.
Note: Press the OFF button of motor when people leave machine or repair it.
6. The maintenance and service of machine
6.1 The cleaning work of machine
The routine cleaning work of machine shall be carried out once per shift, and the overall
cleaning work shall be carried out once per week. The oil filter must be cleaned once per
month.
Suggestion: Raise the main post to the maximum position and clean it. Blow off pollutants
from inside to outside with compressed air during cleaning of oil filter.
6.2 Hydraulic oil level
It is necessary to check the oil level in machine body in application of machine. If it is lower
than the minimum position, the hydraulic oil of the same type shall be supplemented. If there
is severe loss, please find out the reason and take corresponding measurements.
After cumulative 2000 hours or at most no more than 1 year of working time, the hydraulic oil
shall be replaced.
Suggestion: When clean the oil tank just after the machine stops, do not wipe it with wool
yarn.
6.3 The overflow valve, which has been set before leaving factory and locked, can not been
adjusted randomly so as to avoid the machine being damaged due to overload.
6.4 In the material cutting process, any position of plastic backing plate shall be used evenly
and can be rotated 180°in horizontal plane.

The delay timer can not
match with the travel
distance, or there is
leakage or sufficient oil
amount in oil cylinder
position or the oil filter is
