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.
9.

Maintain a firm 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 
controlled 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.

To avoid kickback, do support board or panel near 
the cut. (Fig. 2)
Do not support board or panel away from the cut. 
(Fig. 3)

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 firmly with both hands. 
NEVER place your hand or fingers behind the saw.

If kickback occurs, the saw could easily jump 
backwards over your hand, leading to serious 
personal injury.

 (Fig. 4)

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 may 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 operate automatically.

21.

Always observe that the lower guard is covering 
the blade before placing saw down on bench or 
floor.

 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.

22.

To check lower guard, open lower guard by hand, 
then release and watch guard closure. Also check 
to see that retracting handle does not touch tool 
housing.

 Leaving blade exposed is VERY 

DANGEROUS and can lead to serious personal injury.

Additional safety warnings

23.

Use extra caution when cutting damp wood, 
pressure treated lumber, or wood containing 
knots.

 Maintain smooth advancement of tool without 

decrease in blade speed to avoid overheating the 
blade tips.

24.

Do not attempt to remove cut material when blade 
is moving. Wait until blade stops before grasping 
cut material. 

Blades coast after turn off.

25.

Avoid cutting nails. Inspect for and remove all 
nails from lumber before cutting.

26.

Place the wider portion of the saw base on that 
part of the workpiece which is solidly supported, 
not on the section that will fall off when the cut is 
made. As examples, Fig. 5 illustrates the RIGHT 
way to cut off the end of a board, and Fig. 6 the 
WRONG way. If the workpiece is short or small, 
clamp it down. DO NOT TRY TO HOLD SHORT 
PIECES BY HAND!

27.

Before setting the tool down after completing a 
cut, be sure that the lower guard has closed and 
the blade has come to a complete stop.

28.

Never attempt to saw with the circular saw held 
upside down in a vise. This is extremely 
dangerous and can lead to serious accidents. 
(Fig. 7)

29.

Some material contains chemicals which may be 
toxic. Take caution to prevent dust inhalation and 
skin contact. Follow material supplier safety data.

30.

Do not stop the blades by lateral pressure on the 
saw blade.

31.

Do not use any abrasive wheels.
