Enlarging hole
1. Transverse (width) enlargement

006008
A hole can be enlarged transversely by adjusting the
gauge plate. Max. expansion of hole width is 15 mm
(5/16")
Example:
When cutting a hole 25 mm (1") wide using a
cutter chain 18 mm (23/32"), proceed as
follows:
Push the lever (B) away from you.
•
Loosen the hex bolts securing the
gauge plate.
Adjust the 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 cut again to
enlarge the 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").
2. Longitudinal (length) enlargement
Hole length can be determined in three steps shown in
the table below.
Cutter chain position
Original position
No.1 set position
No.2 set position

NOTE:
A hole a little longer than predetermined may be
•
cut depending upon the cutter chain tension.
The adjusting hex bolts are factory adjusted for
•
cutting holes 90 mm (3-9/16") long in the No.1 set
position and 120 mm (4-3/4")long in the No.2 set
position.

WARNING:
When using pressure to turn the adjusting hex bolt
•
or hex nut, be careful not to allow the adjusting hex
bolt to slip off the set position.
To bring the cutter chain back to the perpendicular
(original) position, pull the lever (C) toward you while
pressing down on the right-hand grip and slightly raising
the left-hand grip and move the cutter chain back to its
original position.
When cutting a hole, first use the perpendicular position,
then No.1 set position and finally No.2 set position.
Always safely hook the tool head back onto the hook
when changing the cutter chain position.
