INSTALLING BIT AND CHISEL
Bit and chisel come boxed together, with the bit inside
the chisel.
Always make sure the mortiser is disconnected from its
power source before starting to install the set.
• Always place the chip escape slot in the chisel shaft
to one side, right or left, never to front or rear.
Handle chisels with care: they are exceptionally
sharp. A small block of wood is a help to hold the
chisel in place while the procedure goes on.
• Open the chuck access doors.
• Open the chuck as far as needed: check by remov-
ing the chisel from its drill, and using the drill shank
to size the chuck opening.

POWER SOURCE
WARNING: Do not connect hollow chisel mortiser to
the power source until all assembly steps have been
completed.
The motor is designed for operation on the voltage and
frequency specified. Normal loads will be handled safe-
ly on voltages not more than 10% above or below spec-
ified voltage. Running the unit on voltages which are not
within range may cause overheating and motor burn-
out. Heavy loads require that voltage at motor terminals
be no less than the voltage specified on nameplate.
. Power supply to the motor is controlled by a rocker
switch. Removing the key from rocker switch will lock
the unit and prevent unauthorized use.
GROUNDING INSTRUCTIONS
WARNING: Improper connection of equipment
grounding conductor can result in the risk of electrical
shock. Equipment should be grounded while in use to
protect operator from electrical shock.
. Check with a qualified electrician if you do not under-
stand grounding instructions or if you are in doubt as
to whether the tool is properly grounded.
. This tool is equipped with an approved cord rated at
150V and a 3-prong grounding type plug (See Figure
12) for your protection against shock hazards.
o Grounding plug should be plugged directly into a
properly installed and grounded 3-prong grounding-
type receptacle, as shown (See Figure 12).

when completely assembled. The hollow chisel mortiser
must be installed in a place with ample lighting and cor-
rect power supply. To install hollow chisel mortiser:
. Make sure there is plenty of room for moving the
workpiece through the entire cut. There must be
enough room that neither the operators nor the
bystanders will have to stand in line with the wood
while using the tool.
. Use this tool only after fastening it to the bench: the
long handle gives needed leverage for mortising, but
also pulls the machine forward and over.
. Insert two lag 5/16"x 2" screws (not supplied), with flat
washers, through the holes in the base, and drive
them into the benchtop, after drilling pilot holes.
. If the mortiser is to be left portable, attach it to a 3/4"
x 13" wide x 16" long plywood base (not supplied)
that can be clamped or bolted to the benchtop.

DESCRIPTION
The Craftsman hollow chisel mortiser is a heaw duty,
portable, machine designed to produce mortises up to
_/2"wide in hardwoods and 3/4"wide in softwoods. Slow
feeds and patience allow the user to create 3/4"wide
mortises in most hardwoods. The Craftsman mortiser is
powered by a 120 volt, 4.0 amps, 60 Hz electric motor.
The mortiser uses hollow chisel mortising tools. While
the Craftsman mortiser is designed for portability, it
should never be used without secure fastening to a
solid bench or other surface to prevent tipping.
