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.

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.

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 ◯

•Install or remove the punch holder
levers only in the position ◯
