617931-00QP350 Circular Saw NEW
Do not attempt to remove cut material when blade is moving.
CAUTION: Blades coast after turn off.
• SUPPORT LARGE PANELS. Large panels must be supported as
shown in Figure 16 to minimize the risk of blade pinching and
kickback. When cutting operation requires the resting of the saw
on the work piece, the saw shall be rested on the larger portion
and the smaller piece cut off.
• USE RIP FENCE. Always use a rip fence or straight edge guide
when ripping.
• GUARD AGAINST KICKBACK. Kickback occurs when the saw
stalls rapidly and is driven back towards the operator. Release
switch immediately if blade binds or saw stalls. Keep blades
sharp. Support large panels as shown in Figure 16. Use fence or
straight edge guide when ripping. Don't force tool. Stay alert-
exercise control. Don't remove saw from work during a cut while
the blade is moving.
• LOWER GUARD. Raise lower guard with the retracting handle.
• ADJUSTMENTS. Before cutting be sure depth and bevel
adjustments are tight.
• USE ONLY CORRECT BLADES IN MOUNTING. Do not use
blades with incorrect size holes. Never use defective or incorrect
blade washers or bolts.
• AVOID CUTTING NAILS. Inspect for and remove all nails from
lumber before cutting.

Motor
Be sure your power supply agrees with nameplate marking. 120
Volts AC only means your tool will operate on standard 60 Hz
household power. Do not operate AC tools on DC. A rating of 120
volts AC/DC means that you tool will operate on standard 60 Hz AC

or DC power. This information is printed on the nameplate. Lower
voltage will cause loss of power and can result in over-heating. All
Black & Decker tools are factory-tested; if this tool does not operate,
check the power supply.
Brushes
DISCONNECT PLUG FROM POWER SUPPLY BEFORE
SERVICING
Inspect carbon brushes regularly by unplugging tool, removing the
Brush Inspection Cap (Fig. 2) and withdrawing the brush assembly.
Keep brushes clean and sliding freely in their guides. Always replace
a used brush in the same orientation in the holder as it was prior to
removal. Carbon brushes have varying symbols stamped into their
sides, and if the brush is worn down to the line closest to the spring,
they must be replaced. Use only identical brushes. Always replace
both brushes. Use of the correct grade of brush is essential for
proper operation. New brush assemblies are available at your
authorized service center. The tool should be allowed to "run in" (run
at no load without a blade) for 10 minutes before use to seat new
brushes.
While "running in" DO NOT TIE, TAPE, OR OTHERWISE LOCK
THE TRIGGER SWITCH ON. HOLD BY HAND ONLY.
Adjustments and Setup
ATTACHING AND REMOVING BLADES
DISCONNECT PLUG FROM POWER SUPPLY.
To attach the blade, retract lower blade guard and place inner
clamp washer and blade on saw spindle with printed side of blade
out (teeth at bottom of blade pointing forward) (FIG. 1.) Place outer
clamp washer on saw spindle. The larger surfaces of both washers
must face the blade. Thread on blade clamping screw firmly by
hand to hold both blade washers in position.
Lightly depress the blade lock (FIG. 2) while turning the spindle
until the blade stops rotating. Tighten blade clamping screw
