the blade lock engages and the blade stops

rotating.

5. Tighten the blade clamping screw firmly with the

blade wrench.

NOTICE: Never engage the blade lock

while saw is running, or engage in an

effort to stop the tool. Never turn the

saw on while the blade lock is engaged.

Serious damage to your saw will result.

TO REPLACE THE BLADE (FIG. 2–5)

1. To loosen the blade clamping screw (k), depress

the blade lock (d) and turn the saw spindle with

the blade wrench (p), stored underneath the

main handle (c), until the blade lock engages

and the blade stops rotating. With the blade

lock engaged, turn the blade clamping screw

counterclockwise with the blade wrench (screw

has right-hand threads and must be turned

counterclockwise to loosen).

2. Remove the blade clamping screw (k) and outer

clamp washer (o). Remove old blade.

3. Clean any sawdust that may have accumulated

in the guard or clamp washer area and check

the condition and operation of the lower blade

guard as previously outlined. Do not lubricate

this area.

4. Select the proper blade for the application

(refer to Blades). Always use blades that are

the correct size (diameter) with the proper size

and shape center hole for mounting on the

saw spindle. Always assure that the maximum

recommended speed (rpm) on the saw blade

meets or exceeds the speed (rpm) of the saw.

5. Follow steps 1 through 5 under To Install the

Blade, making sure that the blade will rotate in

the proper direction.

LOWER BLADE GUARD

WARNING: The lower blade guard is

a safety feature that reduces the risk

of serious personal injury. Never use

the saw if the lower guard is missing,

damaged, misassembled or not working

properly. Do not rely on the lower

blade guard to protect you under all

circumstances. Your safety depends on

following all warnings and precautions

as well as proper operation of the

saw. Check the lower blade guard for

proper closing before each use. If the

lower blade guard is missing or not

working properly, have the saw serviced

before using. To assure product safety

and reliability, repair, maintenance and

adjustment should be performed by

an authorized service center or other

qualified service organization, always

using identical replacement parts.

CHECKING THE LOWER GUARD (FIG. 1)

1. Turn tool off and disconnect from power supply.

2. Rotate the lower guard lever (fig. 1, l) from the

fully closed position to the fully open position.

3. Release the lever and observe the guard (j)

return to the fully closed position.

The tool should be serviced by a qualified service

center if it:

 • fails to return to the fully closed position,

 • moves intermittently or slowly, or

 • contacts the blade or any part of the tool in all

angles and depth of cut.

BLADES

WARNING: To minimize the risk of

eye injury, always use eye protection.

Carbide is a hard but brittle material.

Foreign objects in the workpiece such

as wire or nails can cause tips to crack

or break. Only operate saw when proper

saw blade guard is in place. Mount

blade securely in proper rotation before

using, and always use a clean, sharp

blade.

If you need assistance regarding blades, please

contact your local D

eWALT dealer.

Kickback

Kickback is a sudden reaction to a pinched, bound

or misaligned saw blade, causing an uncontrolled

saw to lift up and out of the workpiece toward the

operator. When the blade is pinched or bound

tightly by the kerf closing down, the blade stalls

and the motor reaction drives the unit rapidly back

toward the operator. If the blade becomes twisted or

misaligned in the cut, the teeth at the back edge of

the blade can dig into the top surface of the material

causing the blade to climb out of the kerf and jump

back toward the operator.

Kickback is more likely to occur when any of the

following conditions exists.

1. IMPROPER WORKPIECE SUPPORT

A. Sagging or improper lifting of the cut off

piece can cause pinching of the blade and

lead to kickback (fig. 24).
