• 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 correc-

tive actions to eliminate the cause of blade bind-

ing.

• 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.

• 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 minimize the risk of blade pinching and kick-

back. When cutting operation requires the resting

of the saw on the workpiece, the saw should be

rested on the larger portion and the smaller piece

cut off. (Fig. 2 & 3)

• Do not use dull or damaged blades. Unsharp-

ened or improperly set blades produce narrow kerf

causing excessive friction, blade binding and kick-

back. Keep blade sharp and clean. Gum and wood

pitch hardened on blades slows saw and

increases potential for kickback. Keep blade clean

by first removing it from tool, then cleaning it with

gum and pitch remover, hot water or kerosene.

Never use gasoline.

• 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.

• Use extra caution when making a “plunge cut”

into existing walls or other blind areas. The

protruding blade may cut objects that can cause

kickback. For plunge cuts, retract lower guard

using retracting handle.

• 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 per-

sonal injury. (Fig. 4)

• Never force the saw. Forcing the saw can

cause uneven cuts, loss of accuracy, and pos-

sible kickback. Push the saw forward at a speed

so that the blade cuts without slowing.

10. 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 posi-

tion. 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. To check lower guard, open lower

guard by hand, then release and watch guard clo-

sure. Also check to see that retracting handle does

not touch tool housing. Leaving blade exposed is

VERY DANGEROUS and can lead to serious per-

sonal injury.

11. Check the operation of the lower guard spring. If

the guard and the spring are not operating prop-

erly, they must be serviced before use. Lower

guard may operate sluggishly due to damaged

parts, gummy deposits, or a build-up of debris.

12. Lower guard should be retracted manually only

for special cuts such as “plunge cuts” and

“compound cuts.” Raise lower guard by retract-

ing 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.

13. 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. Before setting the tool

down after completing a cut, be sure that the lower

guard has closed and the blade has come to a com-

plete stop.

14. Use the appropriate riving knife for the blade

being used. For the riving knife to work, it must be

thicker than the body of the blade but thinner than

the tooth set of the blade.

15. Adjust the riving knife as described in this

instruction manual. Incorrect spacing, positioning

and alignment can make the riving knife ineffective

in preventing kickback.

16. Always use the riving knife except when plunge

cutting. Riving knife must be replaced after plunge

cutting. Riving knife causes interference during

plunge cutting and can create kickback.

17. For the riving knife to work, it must be engaged

in the workpiece. The riving knife is ineffective in

preventing kickback during short cuts.

18. Do not operate the saw if riving knife is bent.

Even a light interference can slow the closing rate of

a guard.

19. Use extra caution when cutting damp wood,

pressure treated lumber, or wood containing

knots. Adjust speed of cut to maintain smooth

advancement of tool without decrease in blade

speed.

20. Avoid Cutting Nails. Inspect for and remove all

nails from lumber before cutting.

21. 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! (Fig. 5 & 6)

22. Never attempt to saw with the circular saw held

upside down in a vise. This is extremely danger-

ous and can lead to serious accidents. (Fig. 7)

23. Some material contains chemicals which may be

toxic. Take caution to prevent dust inhalation

and skin contact. Follow material supplier safety

data.

24. Do not stop the blades by lateral pressure on the

saw blade.

25. Always use blades recommended in this manual.

Do not use any abrasive wheels.
