General Safety Rules   
WARNING: Read all safety warnings and all instructions. Failure 
to follow the  warnings and instructions  may  result in electric shock, 
fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (cord-
ed) 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 ammable 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 ground fault circuit 
interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
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 inuence 
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 protection. Protective 
equipment such as dust mask, nonskid 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 energizing 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 bet-
ter control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing 
and gloves away from moving parts. Loose clothes, jewelry 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 cor-
rect 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 tool’s oper-
ation. If damaged, have the power tool repaired before use. Many accidents are 
caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp 
cutting edges are less likely to bind and are easier to control.
g) 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 qualied repair person using only identical 
replacement parts. This will ensure that the safety of the power tool is maintained.
SPECIFIC SAFETY RULES
 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.
 Always wear eye protection and a respirator when sanding.
 Sanding of lead-based paint is not recommended. Sanding Lead Based Paint See   for 
additional information before sanding paint.
