Additional Safety Instructions for
Circular Saws
• CAUTION: When cutting into walls, floors or wherever live elec-
trical wires may be encountered, DO NOT TOUCH ANY METAL
PARTS OF THE TOOL! Hold the tool only by insulated grasping
surfaces to prevent electric shock if you cut into a live wire.
• KEEP GUARDS IN PLACE AND IN WORKING ORDER. Never
wedge or tie lower guard open. Check operation of lower guard
before each use. Do not use if lower guard does not close briskly
over saw blade. CAUTION: If saw is dropped, lower guard may
be bent, restricting full return.
• KEEP BLADES CLEAN AND SHARP. Sharp blades minimize
stalling and kickback.
• DANGER: KEEP HANDS AWAY FROM CUTTING AREA.
Keep hands away from blades. Do not reach underneath work
while blade is rotating. 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 10 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 10. Use fence or
straight edge guide when ripping. Don'f 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.
• CAUTION: Some wood contains preservatives such as copper
chromium arsenate (CCA) which can be toxic. When cutting
these materials extra care should be taken to avoid inhalation
and minimize skin contact.

Motor
Your D WALT tool is powered by a D

power supply agrees with nameplate marking. 120 Volts AC/DC
means your saw will operate on alternating or direct current. Lower
voltage can cause loss of power and can result in overheating. All

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 either brush is worn down to the line closest
to the spring, they must be replaced. Use only identical D
