2. Longitudinal (length) enlargement
Hole length can be determined in three steps shown in the table below.
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 long
in the No.1 set position and 120 mm long in the No.2 set position.
Push down the right-hand grip while raising the left-hand grip. Make sure that

the adjusting hex bolt slips into place securely.
Loosen the hex nut securing the adjusting hex bolt. Turn the adjusting hex bolt
006010
until the cutter chain reaches the desired position, then tighten the hex nut.
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 posi-

tion and finally No.2 set position. Always safely hook the tool head back onto
the hook when changing the cutter chain position.
