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 tool base with the clamp
screw (A). Loosen the clamp screw (B) and adjust the
distance between the bit and the trimmer guide by
turning the adjusting screw (1 mm per turn). At the
desired distance, tighten the clamp screw (B) to secure
the trimmer guide in place.
