Kickback causes and related warnings

—

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 wood causing the blade to climb

out of the kerf and jump back toward the operator.

Kickback is the result of saw misuse and/or incorrect

operating procedures or conditions and can be avoided

by taking proper precautions as given below.

Maintain a rm grip with both hands on the saw

and position your arms to resist kickback forces.

Position your body to either side of the blade, but

not in line with the blade. Kickback could cause the

saw to jump backwards, but kickback forces can be con-

trolled by the operator, if proper precautions are taken.

10.

When blade is binding, or when interrupting a cut

for any reason, release the trigger and hold the saw

motionless in the material until the blade comes to a

complete stop. Never attempt to remove the saw from

the work or pull the saw backward while the blade is

in motion or kickback may occur. Investigate and take

corrective actions to eliminate the cause of blade binding.

11.

When restarting a saw in the workpiece, centre the saw

blade in the kerf and check that saw teeth are not engaged

into the material. If saw blade is binding, it may walk up or

kickback from the workpiece as the saw is restarted.

12. Support large panels to minimise the risk of

blade pinching and kickback. Large panels tend

to sag under their own weight. Supports must be

placed under the panel on both sides, near the line

of cut and near the edge of the panel.

13. Do not use dull or damaged blades.

Unsharpened or improperly set blades produce

narrow kerf causing excessive friction, blade

binding and kickback.

14. Blade depth and bevel adjusting locking levers

must be tight and secure before making cut. If

blade adjustment shifts while cutting, it may cause

binding and kickback.

15. Use extra caution when sawing into existing

walls or other blind areas. The protruding blade

may cut objects that can cause kickback.

16. ALWAYS hold the tool rmly with both hands.

NEVER place your hand or ngers behind the

saw. If kickback occurs, the saw could easily jump

backwards over your hand, leading to serious

personal injury.

17. Never force the saw. Push the saw forward at a

speed so that the blade cuts without slowing.

Forcing the saw can cause uneven cuts, loss of

accuracy, and possible kickback.

Lower guard function

18. Check lower guard for proper closing

before each use. Do not operate the saw if

lower guard does not move freely and close

instantly. Never clamp or tie the lower guard

into the open position. If saw is accidentally

dropped, lower guard may be bent. Raise the

lower guard with the retracting handle and make

sure it moves freely and does not touch the blade

or any other part, in all angles and depths of cut.

19. Check the operation of the lower guard spring.

If the guard and the spring are not operating

properly, they must be serviced before use.

Lower guard may operate sluggishly due to

damaged parts, gummy deposits, or a build-up of

debris.

20. Lower guard should be retracted manually

only for special cuts such as “plunge cuts”

and “compound cuts”. Raise lower guard by

retracting handle and as soon as blade enters

the material, the lower guard must be released.

For all other sawing, the lower guard should oper-

ate automatically.

21. Always observe that the lower guard is cov-

ering the blade before placing saw down on

bench or oor. An unprotected, coasting blade

will cause the saw to walk backwards, cutting

whatever is in its path. Be aware of the time it

takes for the blade to stop after switch is released.
