General Safety Rules – For All T
ools
W
ARNING! Read and understand all instructions.
Failure to follow all instructions listed below may
result in electric shock, fire and/or serious personal injury
.
SA
VE THESE INSTRUCTIONS
WORK AREA
• Keep your work area clean and well lit.
Cluttered benches
and dark areas invite accidents.
•
Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquids, gases, or dust.
Power tools create sparks which may ignite the dust or fumes.
•
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL
SAFETY
•
Grounded tools must be plugged into an outlet properly
installed and grounded in accordance with all codes and
ordinances. Never remove the grounding prong or modify
the plug in any way
. Do not use any adaptor plugs. Check
with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded.
If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user
. Applicable
only to Class I (grounded) tools.
•
Double insulated tools are equipped with a polarized plug
(one blade is wider than the other
.) This plug will fit in a
polarized outlet only one way
. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet. Do not
change the plug in any way
.
Double insulation
eliminates
the need for the three wire grounded power cord and grounded
power supply system. Applicable only to Class II (double
insulated) tools.
•
Avoid body contact with grounded surfaces such as pipes,
radiators, ranges and refrigerators.
There is an increased risk
of electric shock if your body is grounded.
•
Don’
t expose power tools to rain or wet conditions.
Water
entering a power tool will increase the risk of electric shock.
•
Do not abuse the cord. Never use the cord to carry the tools
or pull the plug from an outlet. Keep cord away from heat,
oil, sharp edges or moving parts. Replace damaged cords
immediately.Damaged cords increase the risk of electric shock.

PERSONAL SAFETY
•
Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use tool while
tired or under the influence of drugs, alcohol, or medication.
A moment of inattention while operating power tools may
result in serious personal
injury
.
• Dress properly
. Do not wear loose clothing or jewelry
.
Contain long hair
. Keep your hair
, clothing, and gloves away
from moving parts. Loose clothing, jewelry
, or long hair can be
caught in moving parts.
Air vents often cover moving parts and
should also be avoided.
•
Avoid accidental starting. Be sure switch is of
f before plug-
ging in.
Carrying tools with your finger on the switch or plugging
in tools that have the switch on invites accidents.
•
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 protection. Dust
mask, non-skid safety shoes, hard hat, or hearing protection
must be used for appropriate conditions.
TOOL USE AND CARE
•
Use clamps or other practical way to secure and support
the workpiece to a stable platform.
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 of
f.
Any tool
that cannot be controlled with the switch is dangerous and must
be repaired.

missing or damaged.
If grinding wheel or accessory loosens,
it may dismount from the machine and may cause serious
personal injury.
•
Always use proper guard with grinding wheel.
A
guard pro-
tects operator from broken wheel fragments and wheel contact.
• Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other acces-
sories running over rated speed can fly apart and cause injury.
Accessory ratings must be above listed minimum wheel speed
as shown on tool nameplate.
•
Hold tool by insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden
wiring or its own cord.
Contact with a “live” wire will make
exposed metal parts of the tool “live” and shock the operator
.
•
AL
W
AYS WEAR EYE PROTECTION WHEN USING THIS
T
OOL.
•
Use of accessories not specified in this manual is not recommended and may be hazardous.
Use of power boosters
that would cause the tool to be driven at speeds greater than its
rated speed constitutes misuse.
•
Do not use circular saw blades or any other toothed blades
with this tool.
Serious injury may result.
• When starting the tool with a new or replacement wheel, or
a new or replacement wire brush installed, hold the tool in
a well protected area and let it run for one minute.
If the
wheel has an undetected crack or flaw
, it should burst in less
than one minute. If the wire brush has loose wires, they will be
detected. Never start the tool with a person in line with the
wheel. This includes the operator
.
• Avoid bouncing the wheel or giving it rough treatment.
If this
occurs, stop the tool and inspect the wheel for cracks or flaws.
•
Disconnect the plug from the power source before making
any adjustments, changing accessories, or storing the tool.
Such preventative safety measures reduce the risk of starting
the tool accidentally.
•
Store idle tools out of reach of children and other untrained
persons.Tools are dangerous 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, break-
age of parts, and any other condition that may af
fect 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.
Accessories that may be suitable for
one tool, may become hazardous when used on another tool.
SERVICE
• Tool service must be performed only by qualified repair
personnel.
Service or maintenance performed by unqualified
personnel could result in a risk of injury.
•
When servicing a tool, use only identical replacement parts.
Follow instructions in the Maintenance section of this manual.
Use of unauthorized parts or failure to follow maintenance
instructions may create a risk of electric shock or injury
.
Additional Specific Safety Instructions
for Grinders
•
Check that the grinding wheel backing flange has a yellow
rubber ring (I) installed, see Figure 1. Replace rubber ring if
missing, damaged or worn. See page 9 for details regarding
proper accessory installation.
WARNING:
The grinding wheel or accessory may loosen
during coast-down of the tool when shut off if rubber ring is
English
6
•
When the wheel is pinched or bound tightly by the workpiece,
the wheel stalls and the motor reaction drives the unit rapidl
y
back toward or away from the operator
.
•
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
•
Maintain a firm grip with both hands on the unit and position your body and arm to allow you to resist kickback
forces.
Kickback forces can be controlled by the operator, if
proper precautions are taken.
•
When wheel is binding, or when interrupting a cut for any
reason, release the trigger and hold the unit motionless
in the material until the wheel comes to a complete stop.
Never attempt to remove the unit from the work or pull
the unit backward while the wheel is in motion or kickback may occur
.
Investigate and take corrective actions to
eliminate the cause of wheel binding.
•
When restarting a cut-of
f tool in the workpiece, check
that the wheel is not engaged into the material.
If wheel is
binding, it may walk up or kickback from the workpiece as the
tool is restarted.
•
Support large panels to minimize the risk of wheel pinching and kickback.
Large panels tend to sag under their own
weight. Support must be placed under the panel on both
sides, near the line of cut and near the edge of the panel.
