For safe operations:
1.
Keep work area clean.
Cluttered areas and benches invite injuries.
2.
Consider work area environment.
Do not expose power tools to rain. Do not use
power tools in damp or wet locations. Keep work
area well lit. Do not use power tools where there is
risk to cause fire or explosion.
Guard against electric shock.
Avoid body contact with earthed or grounded surfaces (e.g. pipes, radiators, ranges, refrigerators).
Keep children away.
Do not let visitors touch the tool or extension cord.
All visitors should be kept away from work area.
Store idle tools.
When not in use, tools should be stored in a dry,
high or locked up place, out of reach of children.
Do not force the tool.
It will do the job better and safer at the rate for which
it was intended.
Use the right tool.
Do not force small tools or attachments to do the job
of a heavy duty tool. Do not use tools for purposes
not intended; for example, do not use circular saws

Turn the adjusting screw to increase the tension on the cutter chain. Pull the
middle of the cutter chain lightly. When there is a clearance of approx. 5 6 mm between the chain bar and the cutter chain, the tension on the cutter
chain is adequate.
After adjusting the tension, tighten the hex bolt firmly to secure the chain bar.
Additionally tighten slightly the adjusting screw. Close the chain cover.
To remove the cutter chain, follow the installation procedures in reverse.

1. Hook
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
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.

•
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.

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.
NOTE:
