GENERAL SAFETY RULES

Personal Safety (continued)

Remove adjusting keys or wrenches before
turning the tool on.
 A wrench or a key that is left
attached to a rotating part of the tool may result in
personal injury.

Do not overreach. Keep proper footing and
balance at all times.
 Proper footing and balance
enables better control of the tool in unexpected
situations.

Use safety equipment. Always wear eye pro-
tection. 
Dust mask, nonskid safety shoes, hard
hat, or hearing protection must be used for
appropriate conditions.

Tool Use and Care

Use clamps or another practical way to secure
and support the workpiece to a stable plat-
form. 
Holding the work by hand or against your
body is unstable and may lead to loss of control.

Do not force tool. Use the correct tool for your
application. 
The correct tool will do the job better
and safer at the rate for which it is designed.

Do not use tool if switch does not turn it on or
off.
 Any tool that cannot be controlled with the
switch is dangerous and must be repaired.

Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing the tool.
 Such preven-
tive safety measures reduce the risk of starting

the tool accidentally.

Store idle tools out of the reach of children
and other untrained persons.
 Tools are danger-
ous in the hands of untrained users.

Maintain tools with care. Keep cutting tools
sharp and clean.
 Properly maintained tools with
sharp cutting edges are less likely to bind and are
easier to control.

Check for misalignment or binding of moving
parts, breakage of parts, and any other condi-
tion that may affect the tool's operation.
 If
damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained
tools.

Use only accessories that are recommended
by the manufacturer for your model.
 Accesso-
ries that may be suitable for one tool, may be-
come hazardous when used on another tool.

Service

Tool service must be performed only by
qualified repair personnel. 
Service or mainte-
nance performed by unqualified personnel could
result in a risk of injury.

When servicing a tool, use only identical
replacement parts. Follow instructions in
Maintenance section of this manual. 
Use of
unauthorized parts or failure to follow Mainte-
nance Instructions may create a risk of electric
shock or injury.

SPECIFIC SAFETY RULES

Specific Safety Rules for Circular Saws

DANGER! Keep hands away from cutting area
and blade. Keep your second hand on the
auxiliary handle or motor housing.
 If both hands
are holding the saw, they cannot be cut by the blade.

Keep your body positioned to either side of the
saw blade, but not in line with the saw blade.
Kickback could cause the saw to jump backwards.
(See "Causes and Operator Prevention of
Kickback.")

Do not reach underneath the work. The guard
cannot protect you from the blade below the work.

Check lower guard for proper closing before
each use. Do not operate 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. Make sure it moves freely and
does not touch the blade or any other part, in all
angles and depths of cut.

Check the operation and condition 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 buildup of
debris.

Lower guard should be retracted manually only
for special cuts, such as "Pocket Cuts" and
"Compound Cuts." Raise lower guard by
retracting handle. As soon as blade enters the
material, lower guard must be released.
 For all
other sawing, the lower guard should operate
automatically.
