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-3
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-4
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,
turn the punch holder levers to the
position ◯
B.
•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-5
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-6
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 non-
genuine 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 V-
groove toward the rear of the machine
for additional safety from breakage.

I-7
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-8
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-9
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.

2. DANGER AND WARNING PLATES
Keep the DANGER and WARNING plates well noticeable and never remove
them.

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.)
