due t o faul ty ma teri al s or wo rkma nsh ip for a
period of 90 days.
During this period, any parts of tools found defective
subject to the guarantee will be replaced at no charge.
Returns should be sent freight PREPAID, in assembled

Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from brick, cement and other
masonry product, and
• Arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well-ventilated
area, and work with approved safety equipment, such as
those dust masks that are specially designed to lter out
microscopic particles.

MAINTENANCE:
If the saw is dropped, the blade guard may be bent,
restricting the full return of the blade guard. With the cord
unplugged, check operation of the blade guard before
each use. Dust build-up can also restrict the full return
of the blade guard. Clear off all dust periodically.
retighten the screw rmly before use. Make sure spindle
lock is pulled out before turning saw on.
DIAMOND BLADE
A diamond blade is available
as an accessory. It's used to
saw out tile under toe spaces or on counters. Also, for
tile repair, it can be used to
remove eld tiles.
Caution: Do not overheat this blade! Cut 6ft. maximum
and allow cooling. Avoid cutting into wood suboors as
this gums up the diamond grit. For best results, lay down
underlayment or plywood at least the width of the saw
so that the diamond blade cuts only to a depth corresponding to the thickness of tile. Make sure no chicken
wire or expanded metal has been installed under tiles
to be cut.

To avoid accidental starting,
DISCON NECT THE SAW
FROM POWER SOURCE
before inserting the cutting
head into the toe-spa ce.
The safest way is by angling it in (Figure 1).
Plug-in the saw. Grasp the
handles rmly and pull the
trigge r. Moving the saw
slowly forward retracts the
guard s and exposes the
blade. Press down on the
handles slowly to p lunge
th e bl ad e in to the cut.
Slowly push the saw forward and along the toe-kick (Figure 2). Do not force the
saw; let the blade cut at the highest RPM possible.
As you complete the cut, release the trigger and make
sure the motor comes to a full stop before removing the
saw from the toe-space. Unplug the saw before removing from the toe-space.

BLADE CHANGE (continued):

No. 787
Keep hands away from the spindle tube and blade housing
(red area). This is not a handle!
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.
This saw is designed for removal of oors or underlayment under toe-spaces. It cuts ush to the wall of the
toe space. Please note these features of the saw.
LOW-PROFILE CUTTING HEAD: Will t under toe-kicks
as low as 3" in height.
SPINDLE LOCK: For blade changes, the spindle lock
stops the blade rotation, so that the blade can be easily
removed. This is NOT to be used as a motor brake!
CARBIDE BLADES & DEPTH OF CUT: The saw comes
with a 3
3
/8" diameter carbide blade (No. 787) that cuts
underlayment up to
3
/4" thick. It cuts to a xed depth
of
3
/4".
DOUBLE-INSULATED:
This saw is constructed with two separate layers of electrical insulation. A saw built with this insulation system
does not need to be grounded. As a result, this saw
comes with a two-prong plug without a ground pole.
DANGEROUS ENVIRONMENTS:
Keep work area clean; clutter invites accidents. Do not use
on damp or wet oors. This saw may throw sparks. Do not
use around ammable gasses. Be sure lighting is good.
ACCIDENTAL STARTING:
To avoid accidental starting, do not carry saw with ngers
on switch. Do not carry the saw while it is plugged in.
CORD ABUSE AND EXTENSION CORDS:
Nev er car ry saw by the cord or yank the cord to
disconnect from an outlet. Keep cords away from heat,
oil, and sharp edges. If the cord is cut or damaged,
replace immediately.
Avoid using long extension cords, as they will cause some
loss of power. To keep the loss to a minimum and prevent
saw from overheating, use a heavy-duty extension cord
with a minimum wire size based on the length of cord that
is needed: 25' = 16 gauge wire, 50' = 14 gauge wire
WEAR SAFETY GEAR:
GENERAL SAFETY
BLADE GUARD:
Always wear safety glasses and ear plugs when using this
saw. Use face or dust mask if cutting operation is dusty.
In the event of blade binding or any interruption of the
cut, release the switch. Hold the saw motionless until the
blade stops. While the blade is still turning, if you remove
the saw from the cut, or pull the saw backwards, this can
cause saw kickback.
Cut slowly, especially when nails may be present. Keep
motor RPMs high at all times.
This saw is not for use in general sawing. Cutting loose
plywood can bind the blade and cause kickback.
Use only Crain No. 787 or No. 789 blades (see back).
Use new, sharp blades at all times.
This saw plunge starts. Plunge slowly before pushing
forward.
HAND POSITIONING:
FEATURES OF THE SAW:
BLADE CHANGE:
WARNING: Regarding carbide blades, use only Crain
No. 787 Carbide-Tipped Blades. The kickback reducing
clutch is calibrated to this blade diameter ONLY!
WARNING: Check the depth of the underlayment to be
cut. If it is less than
3
/4" thick, to prevent suboor damage,
nail down a strip of additional underlayment at least the
width of the saw to adjust the cutting depth. Make sure
the blade cuts through both underlayment thicknesses.
Cutting through a gap can cause binding and kickback.
WARNING: Don't adjust cutting depth by shimming up
the saw by afxing shims to any of its parts, or by manually holding the saw at an elevation off the oor.

PREVENTING & PREPARING FOR KICKBACK
KICKBACK REDUCING CLUTCH
OTHER KICKBACK PRECAUTIONS
Saw kickback is a sudden reaction to a pinched, bound,
or misaligned saw blade, causing the saw to jump backward towards the user.
Saw kickback is preventable. Cutting straight and forward
helps prevent kickback. This prevents the teeth at the back
of the blade from grabbing in the top surface of the wood,
which causes the saw to jump backward.
Always prepare for saw kickback by keeping both hands
on the handles and gripping rmly. Kneel to the side of the
saw, keeping hands and knees out of the kickback arc.
ALLOW MOTOR TO STOP
AT THE END OF THE CUT:
At the end of a cut, allow the
motor to fully stop b efore
removing the saw from the
cut, or removing hands from
the handles. Otherwise, if
the saw blade is still spinning, the saw can catch and kick back toward the user.
This saw has a kickback reducing clutch that helps reduce
kickback forces. If the saw is abused by making anything
other than straight cuts (curves, angles, etc.), OR by attempting to cut backwards rather than forward, the clutch
may disengage. A loud buzzing sound will occur.
If the clutch disengages, immediately release the switch
and allow the motor to stop. Remove the saw from the
cut and allow the blade guard to extend before restarting
the motor and resuming the cut.
The saw's clutch can withstand about 500 disengagements before the saw will no longer transmit sufcient
power to the blade for cutting. At such time factory
service is required. Don't waste the clutch.
