even when the tool is plugged.
At this time, the indication lamp blinks in red and shows
the unintentional restart proof device is on function.
To cancel the unintentional restart proof, return the
switch lever to O position.
Soft start feature

OPERATION

Always hold the tool firmly with

one hand on housing. Do not touch the metal part.
Set the base on the workpiece to be cut without

attains full speed.
3. Move the tool forward over the workpiece surface,
keeping the base flush and advancing smoothly until
the cutting is complete.
► Fig.5
When doing edge cutting, the workpiece surface
should be on the left side of the trimmer bit in the feed
direction.

direction
When using the straight guide or the trimmer guide,
be sure to keep it on the right side in the feed direc-
tion. This will help to keep it flush with the side of the
workpiece.

NOTE: Moving the tool forward too fast may cause
a poor quality of cut, or damage to the trimmer 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.
Templet guide
The templet guide provides a sleeve through which the
trimmer bit passes, allowing use of the trimmer with
templet patterns.

4. Secure the templet to the workpiece. Place the
tool on the templet and move the tool with the templet
guide sliding along the side of the templet.

NOTE: The workpiece will be cut a slightly different
size from the templet. Allow for the distance (X)
between the trimmer bit and the outside of the templet
guide. The distance (X) can be calculated by using
the following equation:
Distance (X) = (outside diameter of the templet
guide - trimmer bit diameter) / 2
Straight guide
The straight guide is effectively used for straight cuts
when chamfering.

nut securely.
4. When cutting, move the tool with the straight guide
flush with the side of the workpiece.
