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)

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 or 1/16" per turn). When adjusting the guide roller up
or down, loosen the wing bolt (C). After adjusting, tighten
all the wing bolts securely.

Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
