OPERATION cont.

1. Kickback is a sudden reaction to a pinched,

bound or misaligned saw blade, which

causes an uncontrolled saw to lift up and

out of the workpiece and toward

the operator.
2. 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

towards the operator.
3. 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 wood. This

causes the blade to climb out of the kerf and

jump back towards the operator.
4. Sawing into knots or nails in the workpiece

can cause Kickback.
5. Sawing into wet or warped lumber can

cause Kickback. (see Fig. 6a)
6. Forcing a cut, or not supporting the workpiece

correctly can cause Kickback. (see Fig. 6a)
7. Kickback is a result of tool misuse and/or

incorrect operating procedures or conditions.

It can be avoided by taking the proper

precautions, on page 19.

OPERATION

SAW BLADES

All saw blades need to be

kept clean, sharp and properly

set in order to cut efficiently.

Using a dull blade places a

heavy load on the saw and

increases the danger of

kickback. Keep extra blades on

hand, so sharp blades are

always available. Gum and

wood pitch hardened on the

blade slows the saw down.

Use gum and pitch remover,

hot water or kerosene to

remove them.

DO NOT use

gasoline.

BLADE GUARD

SYSTEM (Fig. 4)

The lower blade guard, attached to your circular saw, is there for your protection and

safety. It should NEVER be altered for any reason. If it becomes damaged or begins

to return slowly or sluggishly, DO NOT operate your saw until the damage has been

repaired or replaced. ALWAYS leave the guard in its correct operating position when

using the saw.

CAUTION:

NEVER use the saw when the guard is not operating properly.

The guard should be checked for correct operation before each use. If you drop

your saw, check the lower blade guard and bumper for damage at all depth

settings before using.

NOTE: The guard is operating properly when it moves freely and then readily

returns to the closed position. If for any reason your lower blade guard and

bumper does not close freely, take the saw to your nearest Sears Repair Center

for service before using it.
