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 break-
through 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.

standard equipped cutter chain 16.5 mm. If the alignment is off, for some rea-
son, or when using another size cutter chain, loosen the screws and adjust the
yellow indicator plate and indication plate.

NOTE:
• The gauge plate is factory adjusted for cutting a hole 30 mm wide.
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.
