GENERAL SAFETY RULES
WARNING :
Remove the plug from the socket before carrying out any adjustment, servicing or
maintenance. Read all safety warnings and all instructions. Failure to follow the
warnings and instructions may result in electric shock, fire and/or serious injury.
Make sure the voltage corresponds to the type label on the unit. Packing materials
are not toys! Children must not play with plastic bags! Danger of suffocation! The
power tool noise output may exceed 85dB(A) at the workplace. In this instance, wear
ear protection.
WARNING :
Read all enclosed safety warnings and instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/
or serious injury. The term “power tool” in the warnings refers to your power tool or
battery operated (cordless) power tool.
Save all warnings and instructions for future reference.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
-
uids, 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
3
b) 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.
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 and 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) pro-
tected supply. Use of an RCD 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 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 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
the switch or energizing power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning on the power tool. 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 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 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 mea-
sures 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.
plugs with grounded power tools. Unmodified plugs and matching outlets will reduce risk of electric
shock.

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 operation. 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
This will ensure that the safety of the power tool is maintained.
b) When servicing a power tool, use only identical replacement parts. Follow instructions in the Main-
tenance section of this manual. Use of unauthorized parts or failure to follow Maintenance instruc-
tions may create a risk of shock or injury.
WARNING :
To reduce the risk of injury, user must read the instruction manual.
SPECIFIC SAFETY RULES
• Hold the power tool only by the insulated gripping surfaces when performing an operation where
the accessory may contact hidden wiring or its own power cord. Cutting accessory contacting a “live”
wire may make exposed metal parts of the power tool “live” and could give the operator an electric
shock
• Know your power tool. Read operator’s manual carefully. Learn its applications and limitations, as
• Always wear safety glasses. Everyday eyeglasses have only impact-resistant lenses; they are NOT
safety glasses. Following this rule will reduce the risk of serious personal injury.
• Protect your lungs. Wear a face or dust mask if the operation is dusty. Following this rule will re-
duce the risk of serious personal injury.
• Protect your hearing. Wear hearing protection during extended periods of operation. Following this
rule will reduce the risk of serious personal injury.
• Inspect tool cords periodically and, if damaged, have repaired at your nearest authorized service
center. Constantly stay aware of cord location. Following this rule will reduce the risk of electric
• Check damaged parts. Before further use of the tool, a guard or other part that is damaged should
be carefully checked to determine that it will operate properly and perform its intended function. Fol-

• Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any
other conditions that may affect its operation. A guard or other part that is damaged should be prop-
erly repaired or replaced by an authorized service center. Following this rule will reduce the risk of
• Make sure your extension cord is in good condition. When using an extension cord, be sure to use
one heavy enough to carry the current your product will draw. A wire gauge size (A.W.G.) of at least
14 is recommended for an extension cord 50 feet or less in length. A cord exceeding 100 feet is not
recommended. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the
cord. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
• Inspect for and remove all nails from lumber before using this tool. Following this rule will reduce
the risk of serious personal injury.
• Save these instructions. Refer to them frequently and use them to instruct others who may use this
tool. If you loan someone this tool, loan them these instructions as well.
WARNING :
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contain chemicals known to cause cancer, birth defects or
other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals, work in a well ventilated area, and
work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.

ELECTRICAL
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, which eliminates the need for the
usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal
motor components with protecting insulation. Double insulated tools do not need to be grounded.
7
WARNING :
The double insulated system is intended to protect the user from shock resulting
from a break in the tool’s internal wiring. Observe all normal safety precautions to
avoid electrical shock.
NOTE :
Servicing of a tool with double insulation requires extreme care and knowledge
of the system and should be performed only by a qualified service technician. For
service, we suggest you return the tool to your nearest authorized service center for
repair. Always use original factory replacement parts when servicing.
ELECTRIC CONNECTION
This tool has a precision-built electric motor. It should be connected to a power supply that is 120
volts, 60 Hz, AC only (normal household current). Do not operate this tool on direct current (DC). A
substantial voltage drop will cause a loss of power and the motor will overheat. If your tool does not
operate when plugged into an outlet, double-check the power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from a power source, be sure to use an extension
cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a
drop in line voltage, resulting in overheating and loss of p
ower. Use the chart to determine the mini-
mum wire size required in an extension cord. Only round jacketed cords listed by Underwriter’s Labo-
ratories (UL) should be used.
When working outdoors with a tool, use an extension cord that is designed for outside use. This type
of cord is designated with “WA” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.

WARNING :
Keep the extension cord clear of the working area. Position the cord so that it will
not get caught on lumber, tools or other obstructions while you are working with a
power tool. Failure to do so can result in serious personal injury.

WARNING :
Check extension cords before each use. If damaged, replace immediately. Never use
tool with a damaged cord since touching the damaged area could cause electrical
shock resulting in serious injury.
