1. SAFETY RULES

Observe these safety rules to prevent injuries and accidents:
a) Never modify the machine. If the control circuit or other part of the machine
is modified, the ram may malfunction.
b) Whenever the machine is not in use, remove the key from the POWER
ON/OFF keyswitch, and hand it to the chief operator for custody.
c) Assign trained operators to the operation and maintenance of the machine.
d) Inspect the machine before the start of the day's work.
e) Install the machine with a rear clearance of at least 1000 mm {40 in.} where
it is not exposed to direct sunlight. If the electrical equipment of the machine is overheated as a result, the machine may malfunction.
f) Before starting the operation of the machine, check that there are no
persons and obstacles around the machine. Pay particular attention to the rear of the machine. Never place hand tools and parts on the installed dies and the lower beam.
g) Never put your hand or hands between the punches and dies.
I-2
h) When changing the tools, strictly observe the following rules:
Before installing and removing the dies, turn the POWER ON/OFF keyswitch to OFF, remove the key from the keyswitch, and keep it by yourself. (Install and remove the dies as described in “4. Removing tools” and “5. Installing tools” in Part V.)
Before installing and removing the punches, turn the multiple closing limit setting handwheel to close the ram to the desired position, turn the POWER ON/OFF keyswitch to OFF, remove the key from the keyswitch, and keep it by yourself. Never put your hand or hands between the punch and die to support the punch. (Install and remove the punches as described in “4. Removing tools” and “5. Installing tools” in Part V.)
Securely fix the punches, dies, and die holders before applying pressure to them.
When you install and remove the tools with an assistant operator or operators, be sure to coordinate your work with them.
Never put your hands between the punches and dies to support a punch, for example.
When you install a tool by sliding it sideways, take care not to get your hand pinched between it and another tool already installed.
I-3
If your machine is equipped with optional one-touch punch holders, keep the following rules:
When applying pressure to the punches or bending the worksheet,
ONE-TOUCH PUNCH HOLDER
LEVER POSITIONS
POSITION POSITION POSITION
turn the punch holder levers to the position B.
POSITIONS FOR OPERATING LEVER AND INSTALLING AND REMOVING PUNCHES
Install or remove the punch holder levers only in the position B.
Affix the punch holder lever position sticker in an easy-to-see place to prevent procedural mistakes.
i) When you bend worksheets with an assistant operator or operators, you
must press the bar pedal after fully ensuring the safety of all of them.
I-4
j) Before adjusting the stoppers, turn the POWER ON/OFF keyswitch to OFF,
remove the key from the keyswitch, and keep it by yourself. Be sure to adjust the stoppers from the rear of the machine.
k) Correctly set the position where the bending speed of the ram is to be
changed. If this position is not correctly set, the worksheet may start to bend unexpectedly.
l) When bending a small worksheet, set the stroke length of the ram to 6 mm
{0.24 in.} or less, and hold the worksheet as shown on the next page. Take care not to get your fingers pinched between the punches and dies or between the punches and worksheet.
6 mm {0.24 in.} or less
I-5
Hold the worksheet as shown below.
m) If your machine is equipped with an optional backgauge, push the
worksheet against the stoppers of the backgauge after the backgauge is properly positioned. Otherwise the worksheet may be pushed forward when the backgauge moves forward.
n) Use Amada genuine punches and dies on the machine. The machine
performs various controls by reference to the Amada genuine punches and dies. Non-genuine punches and dies are different in brittleness and allowable tonnage from the genuine punches and dies. Use of such non­genuine tools may cause various troubles and detract from safety of the machine.
o) Apply to the installed tools a pressure
that is not higher than the allowable tonnage marked on them. Unless a proper pressure is applied to them, the tools may break and scatter in a dangerous manner. When 2V-dies are used, use the V­groove toward the rear of the machine for additional safety from breakage.
I-6
p) When bending a large worksheet, be careful of its springing upward. Hold
one side of the worksheet or otherwise be ready for its springing upward.
q) Before bending each worksheet, check that the tools are securely installed
and tightened. With a sharp bend or U-bend, the punches and dies may eat into the worksheet and fall together with the worksheet.
I-7
r) When rebending the same worksheet, align the nose line of the punches
with the bend line of the worksheet. If the worksheet is rebent without aligning the lines, abnormal noise may be produced, and the tools may break and scatter in a dangerous manner.
s) Whenever trouble occurs during the operation of the machine, press one of
the EMERGENCY STOP buttons, turn the POWER ON/OFF keyswitch to OFF, remove the key from the keyswitch, keep it by yourself, and fix the problem. When picking a worksheet that has fallen into the machine, be sure to do so from the rear of the machine. As soon as the machine develops trouble, report it to the chief operator.
I-8
t) If the machine suddenly loses its power due to a power failure, the ram may
open to the maximum opening limit. In such a case, hold the worksheet over the ram so that it does not fall.
u) Before walking away from the machine, turn the POWER ON/OFF
keyswitch to OFF, remove the key from the keyswitch, and keep it by yourself.
v) Before opening the electrical enclosure, be sure to turn off the machine
circuit breaker. You may receive an electric shock if you touch any parts in the electrical enclosure.
w) Be sure to perform periodic maintenance on the machine. For the items of
maintenance to be performed, refer to Part VI, Maintenance.
x) Before maintaining or cleaning the machine, turn off the shop circuit breaker,
relieve the residual hydraulic pressure in the machine, and post a sign to inform other workers that the machine is under maintenance.
y) When relocating the machine, ask AMADA about how to move the machine.
If moved incorrectly, the machine may turn over.

1. FUNCTIONS

This machine is a hydraulic press brake of the central pressure application and parallel rising type. It has the following features:
The hydraulic circuit is simplified to minimize oil leakage and facilitate maintenance.
A main cylinder is installed at the center of the ram to minimize the distortion produced in the upper and lower beams during pressure application.
Installed at the center of the ram, a bearing guide unit slides up and down along the main cylinder surface that doubles as sliding surface, in order to keep the upper and lower beams accurately parallel.
A punch-to-die clearance setting unit allows the ram stroke length to be set to a required minimum and the working efficiency to be enhanced as a result.
The bar pedal can be pressed as required to adjust the ram approach speed or stop the ram mid-stroke. This is ideal for bending worksheets on which scribed lines must be aligned with the punch nose line.
Punch holders and die holders are installed in the upper and lower beams and provide for easy installation of punches and dies, respectively.
Standard tools are light in mass, easy to carry, available in many types, and adaptable to a variety of bending operations. (For the tools, refer to their catalogs.)

III-1

1. SUMMARY

1-1. Environmental conditions

Keep the machine at least 10 m {33 ft} away from a welder or any other equipment that may produce electrical noise and magnetic fields.
Where the ambient temperature is not higher than 5 °C {41 °F}, keep the machine and hydraulic pump motor energized during the day's work.
The higher the humidity in the place where the machine is installed, the lower the insulation performance of its electric parts becomes. This results in the premature degradation of the electric parts. Do not install the machine in such a humid place.
Install the machine in a place where it is not subjected to dust, dirt, and organic or corrosive gases.

1-2. Input power source

Power requirement: 200/230/380/400/460 VAC±10% (transformer tap and motor wiring is required), 3 phases, 50/60 Hz±1 Hz
NOTICE
O Supply the machine from a power source independent of a welder or any
other equipment that may produce line voltage variations. Otherwise the machine may misoperate.
