Make sure to turn off the power (electric and

compressed air), before adjusting, cleaning etc.

14-5 Air pressure

Set the air pressure at 4~5 kg/cm2 by regulator.
Do not increase the air pressure over 5kg/cm

, which

may cause trouble.

14-6 Adjustment (Air type)

Height of Cutter
Loosen screw K and adjust lever L in order to set
24 mm of the distance between lower cutter and
upper cutter at the top position (top dead point).

Overlapping of Cutter
1.

Loosen screw M, then loosen screw N until
disappearing of pressurized power of upper
cutter.

Loosen screw O, then adjust screw P in order
to overlap properly between upper cutter and
lower cutter.
