GENERAL POWER TOOL SAFETY WARNINGS
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power tool. Distractions can cause you to
lose control.
ELECTRICAL SAFETY
• 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.
• 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.
• Do not 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 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.
• 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.
FPO
WARNING!
Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals
known to the state of California 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.
FPO
WARNING!
This product may contain lead, phthalates or other chemicals known to the state of California to cause cancer, birth
defects and other reproductive harm. Please wash your hands after use.
FPO
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.

GENERAL POWER TOOL SAFETY WARNINGS
• 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.
PERSONAL SAFETY
• 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.
• 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.
• 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 with the switch on invites accidents.
• 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.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
• 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.
• 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.
POWER TOOL USE AND CARE
• 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.
• 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.
• 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.
• 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.
• 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.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits in accordance with these instructions and in

GENERAL POWER TOOL SAFETY WARNINGS
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 other than those
intended could be hazardous.
BATTERY TOOL USE AND CARE
• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one
type of battery pack may create a risk of fire when used with another battery pack.
• Use power tools only with specifically designated battery packs. Use of any other battery packs
may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects, that can make a connection from one terminal
to another. Shorting the battery terminals together may cause burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery: avoid contact. If contact
accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or burns.
SERVICE
• 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.
SAFETY WARNINGS FOR CUTTING
• Hold power tool by insulated gripping surfaces, when performing an operation where the cutting
accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the operator an electric shock.
• Use clamps or another practical way to secure and support the workpiece to a stable platform.
Holding the work by hand or against your body leaves it unstable and may lead to loss of control.

WORKING HINTS FOR YOUR TOOL
WORKING HINTS FOR YOUR TOOL
If your power tool becomes too hot, especially when used at low speed, set the speed to maximum and run
it with no-load for 2-3 minutes to cool the motor. Avoid prolonged usage at very low speeds. Always keep
the blade sharp.
Always ensure the workpiece is firmly held or clamped to prevent movement.
Any movement of the material may affect the quality of the cutting or sanding finish.
Start your tool before working and turn it off only after you stop working.
Do not start sanding without having the sandpaper fitted.
Do not allow the sandpaper to wear away; it will damage the sanding pad. The guarantee does not cover
sanding pad wear and tear.
Use coarse grit paper to sand rough surfaces, medium grit for smooth surfaces and fine grit for finishing
surfaces. If necessary, first make a test run on scrap material.
Excessive force will reduce the working efficiency and cause motor overload. Replacing the accessory
regularly will maintain optimum working efficiency.
