12.1. TRIMMING THE FITTING FOR THE FRONT PLATE OF
THE LOCK FOR A MAXIMUM "Nt" OF 170 mm
Check that the trimmer is disconnected from the
mains.

CHANGING THE TRIMMING

• Measure the width "N1" (Fig. 11) of the front of the lock and
attach a mortising bit of the correct size to the machine, fo-
llowing the instructions in section 6 of the manual.
MEASURING, MARKING REFERENCE POINTS AND PLACING
THE FC116U ON THE DOOR
• Measure the distance between the box for the lock and each of
the two edges of the front of the lock, giving you measurements
"N2" and "N3" (Fig. 11).
• If the two measurements "N2" and "N3" (Fig. 11) are the same:
Hold the machine against the door, aligning the upper edge of
crossbeam "V" (Fig. 12) with the upper reference mark "rs" (Fig.
12), which aligns the centres of the machine's trimming path for
the lock box and the front plate for the lock.
• If the measurements "N2" and "N3" (Fig. 11) are not the same,
calculate the difference between them, "N2"-"N3"=X mm (Fig.
11) and make a new upper reference mark "rs1" (Figs. 13 and
12), which is X mm in the direction of the side with the greater
measurement, either "N2" or "N3". Then hold the machine aga-
inst the door, aligning the upper edge of crossbeam "V" (Fig. 12),
using the new upper reference mark "rs1" (Fig. 12), which results
in the alignment of the machine's trimming path with the centre
of the front plate for the lock.

ADJUST THE TRIMMING PATH

• Measure the length of the front "NT" (Fig. 11) of the lock and
fix the two longitudinal stops "S1" (Figs. 12 and 14) onto the
corresponding division of the measurement NT, using the scale
on the guide column "S" (Fig. 14).
• Position and fix the two correcting stops for the diameter of
the cutter bit "S2" (Fig. 14) onto the frame corresponding to the
diameter of the cutter bit attached (Fig. 14).
• Adjust the length of the trim on the connecting rod to a mea-
surement somewhat greater than the front of the lock "NT" (Fig.
11), as explained in section 9 (Fig. 6) of this manual.
