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.
Fig.18
NOTE:
The workpiece will be cut a slightly different size
•
from the templet. Allow for the distance (X)
between the 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 - bit diameter) / 2
Trimmer guide (optional accessory)
Fig.19
Trimming, curved cuts in veneers for furniture and the
like can be done easily with the trimmer guide. The
guide roller rides the curve and assures a fine cut.
Install the trimmer guide on the guide holder with the
wing bolt (B). Insert the guide holder into the holes in the
tool base and tighten the wing bolt (A). To adjust the
distance between the bit and the trimmer guide, loosen
the wing bolt (B) and turn the fine adjusting screw (1.5
mm per turn). When adjusting the guide roller up or
down, loosen the wing bolt (C). After adjusting, tighten
all the wing bolts securely.
