SAFETY INSTRUCTIONS
General power tool safety warnings
Warning! Read all safety warnings and all instructions. Failure to follow the warnings and instructions
listed below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference. The term "power tool" in all of the warnings listed below
refers to your mains operated (corded) power tool or battery operated (cordless) power tool.
1. Work area safety
a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b. 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.
c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2. Electrical safety
a. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
b. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord
away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable
for outdoor use reduces the risk of electric shock.
f. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of electric shock.
NOTE: The term "Residual Curent Device (RCD)" can be replaced by "Ground Fault Circuit Interrupter (GFCI)" or by
"Earth Leakage Circuit Breaker (ELCB)".
3. Personal safety
a. Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools may result in serious personal injury.
b. Use personal protective equipment. Always wear eye, ear and respiratory protection. Protective equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will
reduce personal injuries.
c. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or
energising power tools that have the switch on invites accidents.
d. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal injury.
e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in
unexpected situations.
f. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g. If devices are provided for the connection of dust extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can reduce dust-related hazards.
4. Power tool use and care
a. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the
job better and safer at the rate for which it was designed.
b. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source and/or the battery pack from the power tool before making any
adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
d. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
e. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other
condition that may affect the power tools operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
f. Use the power tool, accessories and tool bits etc., in accordance with these instructions, taking into
account the working conditions and the work to be performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
5. Service
a. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
6. Electrical Safety
Your tool is double insulated; therefore no earth wire is required. Always check that the main voltage
corresponds to the voltage on the rating plate.
Warning! If the power cord is damaged, it must be replaced by the manufacturer, authorized Black & Decker
Service Center or an equally qualified person in order to avoid damage or injury. If the power cord is replaced by
an equally qualified person, but not authorized by Black & Decker, the warranty will not be valid.
7. Labels on Tool
The label on your tool may include the following symbols:
V ........... Volts
Read Instructions Manual
A ........... Amperes
Hz ......... Hertz
Use Eye Protection
W........... Watts
min........ minutes
Use Ear Protection
........ Alternating Current
SPECIFIC SAFETY RULES
• Always use proper guard with grinding wheel. A guard protects operator from broken wheel fragments. Always
position the guard so that as much of the exposed disc as possible is pointing away from you.
• Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other
accessories running over rated speed can fly apart and cause injury.
• 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.
ADDITIONAL SAFETY INSTRUCTIONS FOR GRINDERS
• ALWAYS WEAR EYE PROTECTION.
• WEAR EAR PROTECTION. NOISE LEVEL MAY BE AMPLIFIED WHEN GRINDING IN ENCLOSED SPACES.
• KEEP GUARDS IN PLACE.
• Use only accessories having a maximum operating speed at least as high as the speed specified in the warning on
the tool's label.
• Before using, inspect recommended accessory for cracks or flaws. If such a crack or flaw is evident, discard the
accessory. The accessory should also be inspected whenever you think the tool may have been dropped.
• When starting the tool (with a new or replacement wheel or brush installed) hold the tool in a well protected area and
let it run for one minute. If the wheel or brush has an undetected crack or flaw, it should burst or separate in less than
one minute. Never start the tool with a person in line with the accessory. This includes the operator.
• In operation, avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and inspect the wheel.
• ALWAYS USE GUARDS with grinding wheels and wire brushes. Always position the guard so that as much of the
• Clean your tool out periodically.
• Do not use Type 1 flat cut-off abrasive or diamond wheels without proper guard. (Guard not included with unit.)
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction
