SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS cont.
!
WARNING: Read all safety warnings and 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 electric (corded) power tool or
battery-operated (cordless) power tool.
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
4. Make your workshop childproof with padlocks and master switches. Lock
tools away when not in use.
5. MAKE SURE the work area has ample lighting so you can see the work and that
there are no obstructions that will interfere with safe operation BEFORE using your
power tool.
PERSONAL SAFETY
1. 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.
2. 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.
3. 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.
4. 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.
5. Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
6. 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.
7. 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.

TOOL USE AND CARE SAFETY
!
WARNING:
operating this tool. Failure to follow all instructions listed below may result in
electric shock, fire and /or serious personal injury.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits etc., in accordance with these
instructions and in the manner intended for the particular type of power tool,
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.
8. Use clamps or another practical way to secure and support the workpiece to a
stable platform.
9. Holding the work by hand or against your body leaves it unstable and may lead
to loss of control.
BE SURE to read and understand all instructions before
ELECTRICAL SAFETY
!
WARNING:
installing or removing the plug from the outlet.
1. 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.
2. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter
plugs with grounded power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.

3. 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.
4. Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
5. 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.
6. When operating a power tool outdoors, use an extension cord suitable for outdoor
use marked “W-A” or “W”. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
7. If operating a power tool in a damp location is unavoidable, use a Ground Fault
Circuit Interupter (GFCI) protected supply. Use of a GFCI reduces the risk of
electric shock.
EXTENSION CORDS
USE PROPER EXTENSION CORD. 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. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage
number, the heavier the cord.

SERVICE SAFETY
1. If any part of this tool is missing or should break, bend, or fail in any way;
or should any electrical component fail to perform properly: SHUT OFF the power
switch and remove the saw’s plug from the power source and have the missing,
damaged or failed parts replaced BEFORE resuming operation.
2. 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.
3. If the replacement of the supply cord is necessary, this has to be done by the
manufacturer or his agent in order to avoid a safety hazard.
SAFETY RULES FOR HAMMER DRILLS
1. Know your Professional Hammer Drill. Read operator’s manual carefully. Learn
its applications and limitations, as well as the specific potential hazards related
to this tool. Following this rule will reduce the risk of electric shock, fire, or
serious injury.
2. BE SURE that twist drill bits, drive bits, hammer drill bits and other accessory
attachments are properly and securely mounted in the chuck jaws BEFORE
operating the hammer drill.
3. ALWAYS carefully inspect the material you are going to drill into. Drilling into nails,
pipes and electrical wires can cause serious personal injury.
4. HOLD HAMMER DRILL by insulated gripping surfaces (handles) when performing
an operation where the tool may drill into hidden wiring. Contact with a “live” wire
will make the exposed metal parts of the tool “live” and shock the operator.
5. NEVER hold the piece being drilled in your hands or across your legs. It is
important to support and clamp the workpiece properly in order to minimize body
exposure, bit binding, or loss of control.
