DETERMINE WIDTH OF CUT
Measure the width of the lock box at its widest point, including any protruding parts.
DO NOT INCLUDE THE LOCK FACE. Select a mortise bit equal to, or slightly larger
than this width.
Do not use mortise bits with a diameter in excess of 1-1/4".
EXAMPLE:
1)
Overall width of lock box – 31/32" (24.6 mm) Use PORTER-CABLE
#43704PC 1" (25.4 mm) diameter bit.
2)
Overall width of lock box – 3/4" (19.1 mm) Use PORTER-CABLE #43703PC
3/4" (19.1 mm) diameter bit.
Various sizes of mortise bits are available as accessories.
Disconnect the tool from the power source and exercise
extreme care when handling the cutter to avoid bodily injury or damage to
the cutting edge.
Thread the selected bit on the end of the splined cutter shaft. Tighten securely.
DETERMINING LENGTH OR HEIGHT OF CUT
Measure the height of the lock box (Fig. 5), including any protruding parts. DO NOT
INCLUDE THE LOCK FACE.

SETTING MORTISER FOR LENGTH OF CUT
To reduce the risk of injury, turn unit off and disconnect it from
power source before installing and removing accessories, before adjusting or
when making repairs. An accidental start-up can cause injury.
Set the mortiser for the length of cut (Fig. 6). Turn the adjusting knob (U) until the
correct graduation mark on the slide aligns with the line on the crank-pin indicating
washer (T). If you find that the adjusting knob (U) is difficult to move, turn the crank (E)
Fig. 8 until the tension is relieved.
EXAMPLE: If you want your mortise to be 4" (101.6 mm) long, turn the adjusting
knob (U) Fig. 6 until the graduation mark aligns with the line on the crank-pin indicating
washer.
SETTING MORTISER FOR DEPTH OF CUT
To reduce the risk of injury, turn unit off and disconnect it from
power source before installing and removing accessories, before adjusting or
when making repairs. An accidental start-up can cause injury.
