SETTING MORTISER FOR LENGTH OF CUT
Disconnect tool from power source!
Set the mortiser for the length of cut
(Fig. 6). Loosen the crank pin nut (T)
and turn the adjusting knob (U) until the
correct graduation mark on the slide
aligns with the line on the crank-pin
indicating washer. If you find that the
adjusting knob (U) is difficult to move,
turn the crank (E) Fig. 8 until the tension
is relieved. Tighten the crank pin nut (T),
Fig. 6 securely.
EXAMPLE: If you want your mortise to be 4" (101.6 mm) long, turn the adjusting
knob (U) until the Fig. 6 graduation mark aligns with the line on the crank-pin
indicating washer.
SETTING MORTISER FOR DEPTH OF CUT
Disconnect tool from power source!
Measure the lock box at its deepest part, including the thickness of the lock face.
Add 1/4" (6.4 mm) for clearance. The depth of cut is controlled by the feed rod
(W) Fig. 7 which is marked in 1/4" (6.4 mm) increments. Loosen the collar (X) and
move it to the determined depth requirement. Lock it in place.
MAKING A TRIAL CUT
After set-up, make a trial cut to ensure the fit of the lock box.
1. Clamp a length of 2" x 6" (50.8 x 152.4 mm), or larger lumber in vise, or
fasten it securely to a work bench, in an upright position.
