Enlarging hole
1 . Transverse (width) enlargement
A hole can be enlarged transversely by
adjusting the gauge plate. ILlaR. expan-
sion of hole width is
15 mm (9/16").
Example :
When cutting a hole
25 mm (1") wide
using a cutter chain
18mm (23/32"),
proceed as follows:
Push the lever
( B ) away from you.
Loosen t h e hex bolts securing the gauge
plate. Adjust t h e gauge plate
so
that the
travel distance
(D) is 7 mm (9/32"); that
is,
25 mm (1") - 18 mm (23/32")
=
7 mm (9/32"). Tighten the hex bolts
to secure the gauge plate. Cut the first hole with
the lever ( B ) pushed away from you. Then pull the lever ( B ) toward you and c u t again
to enlarge t h e hole.
NOTE
:
The gauge plate is factory adjusted for cutting a hole
30 mm (1-3/16") wide using a
cutter chain
18 mm (23/32").
Cutter chain position
Original position
No. 1 set position
No. 2 set position
2. Longitudinal (length) enlargement
Hole length can be determined in three steps shown in the table below.
Hole length to be c u t
52.5 mm (2-1/16")
52.5 mm (2-1/16") - 105 mm (4-1/8")
77.5
mm (3-1/16") - 130 mm (5-1/8")
NOTE :
. A hole a little longer than predetermined may be c u t depending upon the cutter

in the
No. 1 set position and 120 mm (4-3/4") long in the No. 2 set position.
