OPERATION

Fig.9
Grasp firmly the grips on either side. Switch on the tool
and wait until the cutter chain attains full speed. Then
release the hook and lower the tool head to cut in the
workpiece. Do not apply excessive pressure to the tool.
This may not only decrease the working efficiency but
also cause a dangerous reaction. Feed slowly at the
beginning of a cutting operation, at the time of hole
breakthrough and when cutting a knot in the workpiece.
After cutting, gently raise the tool head until you can
hook the tool head back onto the hook. Then switch off
the tool. Raise the lever (A) and remove the tool from the
workpiece.
WARNING:
Always hook the tool head back onto the hook
•
when not operating the tool.
Never attempt to cut a twisted or warped
•
workpiece which the tool is not secured firmly to.
Adjusting indicator plate and indication plate
The yellow indicator plate and indication plate are
factory adjusted for the standard equipped cutter chain
16.5 mm. If the alignment is off, for some reason, or
when using another size cutter chain, loosen the screws
and adjust the yellow indicator plate and indication plate.
Enlarging hole
1. Transverse (width) enlargement
Fig.10
A hole can be enlarged transversely by adjusting the
gauge plate. Max. expansion of hole width is 15 mm.
Example:
When cutting a hole 25 mm wide using a
cutter chain 16.5 mm, 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 8.5 mm; that is, 25 mm -
16.5 mm = 8.5 mm. 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 wide.
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
006562
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.
Fig.11
Loosen the hex nut securing the adjusting hex bolt. Turn
the adjusting hex bolt until the cutter chain reaches the
desired position, then tighten the hex nut.
Fig.12
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.
Fig.13
When enlarging
longitudinally, cut the holes in the order indicated from
No.(1) to (6) as shown. This makes for more easy and
efficient hole enlargement.
Fig.14
WARNING:
Never attempt to enlarge a hole with the cutter
•
chain still within the hole. This will cause
unstable and dangerous operation.
Never angle the cutter chain when cutting the first
•
hole, or a dangerous kickback may result. Always
have the cutter chain set to the perpendicular
position when cutting the first hole.
Lap joints up to 130 mm can be cut with this tool.
Fig.15
NOTE:
Lap joints can be cut only on the front (side away
•
from you) of the workpiece.
