210mm CIRCULAR SAW

- If the blade becomes twisted or misalign 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.

a. 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.

b. 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.

c. When restarting a saw in the work-piece, center 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 work-piece as the saw is restarted.

d. Support large panels to minimize 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.

e. Do not use dull or damaged blades.

Unsharpened or improperly set blades product narrow

kerf causing excessive friction, blade binding and kickback.

f. 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.

SAFETY INSTRUCTION FOR CIRCULAR SAW WITH INNER

PENDULUM GUARD

a. 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 parts, in all angles and depths of cut.

b. 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.

c. Lower guard should be retracted manually only for special cuts such as“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.

d. 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,
