Installing or removing the bit
003257
CAUTION:
• Install the bit securely. Always use only the wrenches provided with the
tool. A loose or overtightened bit can be dangerous.
• Do not tighten the collet nut without inserting a bit. It can lead to
breakage of the collet cone.
Insert the bit all the way into the collet cone and tighten the collet nut securely
with the two wrenches.
A 6 mm or 1/4" collet cone is also provided as standard equipment besides the
8 mm or 3/8" collet cone that is factory installed on the tool. Use the correct
size collet cone for the bit which you intend to use.
To remove the bit, follow the installation procedure in reverse.
Set the tool base on the workpiece to be cut without the bit making any con-
tact. Then turn the tool on and wait until the bit attains full speed. Lower the
tool body and move the tool forward over the workpiece surface, keeping the
tool base flush and advancing smoothly until the cutting is complete.
When doing edge cutting, the workpiece surface should be on the left side of
the bit in the feed direction.

• Moving the tool forward too fast may cause a poor quality of cut, or
damage to the bit or motor. Moving the tool forward too slowly may burn
and mar the cut. The proper feed rate will depend on the bit size, the kind
of workpiece and depth of cut. Before beginning the cut on the actual
workpiece, it is advisable to make a sample cut on a piece of scrap
lumber. This will show exactly how the cut will look as well as enable you

to check dimensions.
• When using the straight guide, be sure to install it on the right side in the
feed direction. This will help to keep it flush with the side of the
workpiece.
