SAFETY FIRST
This Multi-Undercut Saw is designed for undercutting affixed
wooden door jambs, moldings, or base, to allow new floor
coverings to be fit underneath. Do not use this saw for sand-
ing floors, cutting metal, or any other purpose not described
in this instruction manual. Please read all instructions.
WORKING TERMINOLOGY:
see
Figure 1
BLADE REMOVAL:
see Figure 2
BLADE INSTALLATION:
see Figure 3
Switch off and unplug
saw, with blade stopped.
Place the blade spacer
over the spindle.
Place the saw blade on
top of the blade spacer.
Place the blade clamp
through the arbor hole
of the blade with the
bottom slot of the blade
clamp properly aligned
with the spindle.
Screw in and re-tighten
the blade screw. Push in
the spindle lock button
to tighten. Be sure to
tighten firmly before use.
HEIGHT ADJUSTMENT:
see Figure 4
Switch off and unplug the
saw. Blade must be stopped.
The depth adjuster accurate-
ly controls depth of cut from
either straight-on (Figure 5)
or a 45˚ angle (Figure 6).
To adjust, loosen the three-
arm knob on the depth
gauge and move the depth
gauge in and out as required
(Figure 7).
A depth gauge adjustment
scale is provided just behind
the three arm knob with nine
1/8" increments (Figure 7).
Re-tighten the three-arm
knob firmly before use.
We recommend that you set
the depth of cut to no more
than 1/2" to minimize the
chance of hitting wall studs
or nails, etc.
Remove the depth gauge
when cutting inside corners.
DEPTH ADJUSTMENT:
Switch off and unplug the saw. Blade must be stopped.
Loosen two wing screws on height adjuster about 1-1/2
to 2 turns. Do not back off the wing screws more than
necessary.
Adjust the height of your blade by moving the height ad-
juster up or down until desired height of cut is achieved.
The inside of the height adjuster has 10 reference lines, in
height increments of 3/32" (.093"- one blade thickness).
Use the reference lines as a guide (Fig. 4). The hous-
ing must be set parallel to the floor. Make certain that
the bottom edge of the housing is set parallel with a
Figure 4
reference line. This is
critical for safety and
straight undercutting.
The maximum height
adjustment is 1".

screws before use.
USING THE SAW:
Make sure the blade screw
and handle screws are tight-
ened securely. Make sure
blade is parallel with the floor.
Keep handle in vertical posi-
tion for general undercutting.
Turn the handle away from
the toe kick for undercutting
toe spaces (see Figure 8).
Plug-in the saw; hold firmly
and push the switch forward to turn the power unit ON.

Retract the height ad-

Push the lock button
down with one hand and
insert the hex wrench
into the blade screw with
other hand, then turn
until the spindle engag-
es with the lock button
(blade stops rotating).
Hold onto the plastic housing; then, push hard on the
hex wrench counter-clockwise to open. If the blade is
very hard to remove, use a vise grip to hold the blade.

HANDLES:
Keep both hands on the handles until the blade stops.
KICKBACK HAZARDS:
While cutting, do not force the saw.
Also, keep the housing flat on the floor and the blade parallel
to the floor at all times. Angling may cause powerful, danger-
ous kickback. Keep the saw RPMs high. Using a dull blade
will place a heavy load on your saw and increase the danger of
kickback. Use only Crain replacement blades.
EYE & EAR PROTECTION:
Always wear safety glasses when
using a power tool. Wear ear plugs when using this saw.
BLADE GUARD:
The blade guard attached to your saw
is for your safety and protection. If it becomes damaged,
do not operate your saw until it has been repaired. Always
leave blade guard in operating position when using the saw.
DOUBLE-INSULATED:
This tool is constructed with two
separate layers of electrical insulation. A tool built with this
insulation system does not need to be grounded.
DANGEROUS ENVIRONMENTS:
Keep work area clean;
clutter invites accidents. Do not use the saw on damp or
wet floors. Be sure that there is good lighting. This saw
may throw sparks. Make certain that flammable materials,
especially explosive vapors, are not present. Use a face or
dust mask if the cutting operation creates dust.
ACCIDENTAL STARTS:
Do not carry with fingers on switch
or while plugged in. When carrying, blade must be stopped.
CORD ABUSE:
Never carry the saw by the cord or yank the
cord to disconnect from an outlet. Keep cords away from
heat, oil, and sharp edges.
EXTENSION CORD:
To minimize power loss and prevent
overheating, use maximum of 25 feet long and 16 AWG.
HAIR & CLOTHING:
Keep all loose hair and clothing away
from the spinning blade at all times.

To start a cut, use the wall to push the blade guard back
and expose blade.
DO NOT USE YOUR HAND!
