DO NOT INCLUDE the exterior decorative face of
the lock.
Check that the trimmer is disconnected
from the mains.
- Place a mortising trimmer bit of the measurement
taken or slightly larger, according to the instructions
in section 6.
9. ADJUSTING THE TRIMMING LENGTH
- Measure the longest point, "H", of the lock box,
including any protuberance it may have (Fig. 4).
DO NOT INCLUDE the exterior decorative face of
the lock.
Check that the trimmer is disconnected
from the mains.
- To adjust the machine to the required trimming
length "H", loosen nut "P" (Fig. 5) with key "F" and
move screw knob "R" until the length indicator "S"
reaches the desired measurement "H", then tighten
nut "P" in this position.
Be sure to tighten nut "P" (Fig. 5); if
not, this may cause the trimming length
adjustment mechanism to break.
The centring of the bit over the thickness of the door
or the part to be mortised is automatic if the small
plates "J1" (Fig. 7) are in the "0" position on the two
clamp vise guides "V1" (Figs. 7 and 9).
10. ADJUSTING THE TRIMMING DEPTH
- Measure the depth "T" (Fig. 4) of the lock box in-
cluding any protuberance it may have at the bottom,
the thickness of the exterior decorative face and an
additional few centimetres as allowance.
Check that the trimmer is disconnected
from the mains.
- The trimming depth is controlled by the graduated
rule "U2" (Fig. 6), marked in 1 mm divisions. Loosen
knob "W" and position ring "V" so that the inside
face coincides with the required depth, then tighten
knob "W" in this position.

11. TEST TRIMMING
- Having made the prior adjustments as explained in
the above sections, it is recommended to check the
results of the latter with the dimensions of the lock box
to be mounted by carrying out a test trimming.
- Secure a 4x15 cm section wooden beam vertically
in the bench screw or fix well by other means.
Check that the trimmer is disconnected
from the mains.
- Loosen knob "K" (Fig. 9). Turn the locking bar "J"
(Figs. 6 and 9) to the horizontal position and help
the motor to rise by supporting it manually, until it
reaches the end of its path.
- Place the mortising trimmer on the wooden beam
(Fig. 7) so that the slot of the position bar "D1" (Fig.
8), which marks the centre of the tool, coincides
with the centre line of the mortising outline. Fasten
the trimmer on the beam and firmly fix the clamp
vises "X" (Fig. 7) using the crank handles "K1" (Figs.
7 and 9).
- Check that the advance crank handle "A" (Fig. 7) is
able to turn freely over the whole path.
- Turn locking bar "J" (Fig. 6) to the vertical position
to gear the trimming depth advance mechanism.
Check to ensure that the motor switch
is in the "ON" position and that lateral
fixing stop "Z" (Fig. 7) is loosened.
- Disconnect the lock mortiser from the mains.
- Start up the motor, pushing lever "Y" (Fig. 7) and
fix it with fixing stop "Z".
- Turn the advance crank handle "A" (Fig. 7) repea-
tedly to effect a synchronised tool advance, both
lengthways and in depth, to the end of the path as
fixed in section 10.
- Stop the machine by activating lever "Y" (Fig. 7).
Disconnect the trimmer from the
mains.
- Turn locking bar "J" (Fig. 6) to the horizontal po-
sition, so freeing the tool advance mechanism and
help the motor to return by supporting it with both
hands to the end of its path.
- Remove the trimmer from the wooden beam and
check the fit of the lock in the trimmed setting, in
