Step 3 Li the Upper cutter Disc ( 8) of the ma-
chine by using its cam lever (18) Unscrew and
take out knob (17) on pivot pin (9) and mount
punched / drilled gasket on pivot pin (9) to rest
on support plate and then tighten knob (17)
from top.
Step 4 - Set the radius of required gasket size
( 1/2 of diameter ) aer loosening lock screw
(32) and sliding moveable scale (5) in its slot,
tighten the lock screw (32) when the desired
radius is adjusted against the edge for setting.
Step 5 - Lower the upper cutter disc (8 ) by
operating cam lever (18) so that, the cutter bites
in the gasket.

it ,so that the gasket moves. Hold the gasket and
feed it along the markings below the upper
cutter disc (8) e cutter will cut the gasket
along the marking , as long as handle is rotated
