your hands can be removed from the workpiece
when the bend is made. Set the forming speed
to avoid excessive part ~whip".
12. Releasing the footswitch of your CINCINNATI
press brake will immediately stop or reverse
(depending upon the mode selection) downward
travel of the ram in case of emergency.
13. When you leave the machine, place the ram at
bottom of the stroke or place safety blocks in
position under the ram. Turn OPERATOR CON-
TROL selector to «OFF" and remove the key ..
even if you will be away for only a few minutes.
14. Have the routine scheduled maintenance and
adjustments performed as shown on the
Maintenance Checklist in Section 6.
15. Check alignm~t of the dies before operating the
machine after the dies have been changed or if
the machine has been idle overnight.. Improper
alignment could cause chipping and flying chips
can cause lacerations and eye injuries.
16. Report any cuts, bruises and all other injuries
to your supervisor or the medical department
immediately. They are the best judges of how
serious or minor the nature of your injUry is.
GENERAL GUIDELINES FOR
INSTALLING, REMOVING AND
TRANSFERRING TOOLING (DIES)
Installing, removing and transferring tooling is haz-
ardous and should be done with proper supervision
by experienced set-up men. Improper handling
techniques can cause muscle ,strains, hernias or
serious disabling injUries.
1. Transfer dies using the proper techniques for
the weight of the die{s) being handled:
a. Very light dies (up to 50 pounds) can be car-
ried manually or transferred on a die truck.
b. Dies weighing over 50 pounds or those that
are awkward to move should be handled by a
hoist.
If the punch or die has tapped holes for lifting
attachments, be sure the proper size bolts are
used. A bolt smaller in diameter than the
tapped hole will slip Qut and cause serious
injUry. If no lifting attachments are prOVided ..
use only approved rope slings so the dies will
not be nicked or scratched.
Lift the dies high enough to clear any obstruc-
tions .. but no higher.

CAUTION
2. When installing and setting-up dies:
a. Clean the machine and filler block surfaces to
which the dies will be fastened. Always turn
machine OFF and use safety blocks between
the bed and ram when working in this area.
b. Inspect the dies for chips, cracks or other
hazardous conditions. Wipe them off with a
clean cloth.
c. Always place the machine control MODE
selector in the "INCH" position so the ram
can only be cycled by use of palmbuttons.
d. Never reach into or through the die area
when . aligning the dies or setting the gaging.
3. When removing dies from the press brake:
a. Clear the work areas of all stock, containers,
tools and other eqUipment.
b. After placing safety blocks between the dies
and turning OFF the machine, clean both
upper and lower dies using a bench brush
and finally wipe clean with a cloth.
c. Place the machine control MODE selector in
the "INCH" position so the ram can only be
cycled by use of the palmbuttons.
d. Never loosen the ram clamp bolts unless the
dies are in a closed position and the drive
motor has been shut «OFF".
