WARNING!
• Read all safety warnings, instructions, illustrations and
specifications provided with this power tool. Failure to
follow all instructions listed below may result in electric
shock, fire and/or serious injury.
GENERAL POWER TOOL SAFETY WARNINGS
• Save all warnings and instructions for future reference.
• The term “power tool” in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmosphere, 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 adaptor plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce risk of electrical 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.
• 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.

6 7
• 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
that have 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.
• Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe
injury within a fraction of a second.
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 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 remove the battery pack,
if detachable, 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 and accessories. 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, 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.
• Keep handles and grasping surfaces dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not allow for safe handling and control of
the tool in unexpected situations.
POWER TOOL USE AND CARE
• Ensure the switch is in the “off” position before inserting the battery pack.
Inserting the battery pack into power tools that have the switch “on” invites accidents.
• When recharging, use only the charger that is 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 only specifically designated battery packs with power tools. The use of any
other battery pack may create a risk of injury or fire.
• When the battery pack is not in use, keep it away from objects that can create
a connection between the terminals, such as paper clips, coins, keys, nails,
screws or other small metal objects. Short-circuiting the battery terminals 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,
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.
SPECIFIC SAFETY RULES FOR BELT SANDER
• Hold the power tool by insulated gripping surfaces, because the sanding
surface may contact its own cord. Cutting a “live” wire may make exposed metal
parts of the power tool “live” and could give the operator an electric shock.
• Never leave the trigger locked “ON”. Before plugging the tool in, check that
the trigger lock is “OFF”. Accidental start-ups could cause injury.
• Unplug the sander before changing accessories. Accidental start-ups may occur
if sander is plugged in while changing an accessory.
• Keep your fingers and clothing away from the belt. They could get cut or
wedged between the pulley, belt and motor housing.
• Clamp or secure workpiece when sanding. Clamping the workpiece prevents it
from being ejected from under the sander and leaves both hands to control the tool.
• Do not wet sand with this sander. Liquids entering the motor housing is an
electrical shock hazard.
• Always wear safety glasses. Everyday eyeglasses 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.

learn their meaning. Proper interpretation of these symbols will allow you to operate the
product better and safer.
DOUBLE-INSULATED TOOLS
• To reduce the risk of electric shock, double-insulated tools are equipped with
a polarized plug (one blade is wider than the other). This
plug will fit into a polarized outlet only one way. If the
plug does not fit into the outlet properly, 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.
• Double insulation eliminates the need for the three-
wire grounded power cord and grounded power supply
system. This sander is a double-insulated tool.
