General power tool safety warnings
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
(corded) power tool or battery-operated (cordless) power tool.
WORK AREA SAFETY
1
a) Keep work area clean and well lit. Cluttered and dark areas
invite accidents.
b) 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.
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 residual current device (RCD) protected 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.
Use safety equipment. Always wear eye protection.Protective
b)
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 offposition 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.
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 better control of the power tool in unexpected
situations.
3
f) 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.
g) If devices are provided for the connection of dust extraction
and collection facilities, ensure these are connected and properly
used. Use of these devices can reduce dust related hazards.
POWER TOOL USE AND CARE
4
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 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 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.
SERVICE
5
a) 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.
Additional safety points for your
finishing sander
Remove the plug from the socket before carrying out any
1
adjustment, servicing or maintenance.
Fully unwind cable drum extensions to avoid potential
2
overheating.
When an ex tension cable is required you must ensure it has
3
the correct ampere rating for your power tool and is in a safe
electrical condition.
Ensure your mains supply voltage is same as indicated on the
4
rating plate.
Your tool is double insulated for additional protection against a
5
possible electrical insulation failure within the tool.
Always check walls, floors and ceilings to avoid hidden power
6
cables and pipes.
After long working periods external metal parts and accessories
7
could be hot.
4
If possible, ensure the workpiece is firmly clamped to prevent
8
movement.
Your finishing sander is a hand held tool, do not clamp your
9
finishing sander.
Before sanding, check the area is free of nails, screws, etc.
10
Never stop the finishing sander by applying a force to the
11
baseplate.
Only use paper in good condition. Do not use torn or worn paper.
12
Do not sand material containing asbestos due to a health risk.
13
Do not sand lead based paint due to the risk of lead poisoning.
14
Do not eat or drink in the working area of the sander.
15
Do not allow people to enter the working area without wearing
16
a dust mask.
Where possible, seal off the working area to contain the dust for
17
later removal.
Your tool is designed for dry sanding only, not wet sanding.
18
Your tool is designed for general purpose light polishing of
19
wood and metals.
Do not sand magnesium material due to the risk of fire.
20
Always wear safety glasses or eye shields when using the
21
sander. Everyday eyeglasses have only impact-resistant lenses;
they are NOT safety glasses. Following this rule will reduce the
risk of serious personal injury.
Always wear hearing protection during extended periods of
22
operation. Following this rule will reduce the risk of serious
personal injur y.
Harmful/toxic dusts will arise from sanding e.g. lead painted
23
surfaces, woods and metals. Contact with or inhalation of these
dusts can endanger the health of operator and bystanders.
Always use eye glasses and dust mask.
Warning: Some dust particles created by power sanding,
sawing, grinding, drill and other construction jobs 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.
•
Arsenic and chromium from chemically treated lumber.
•
Your risk from these exposures varies, depending upon how often
you do this type of work.
To reduce your exposure to these chemicals:
Work in a well-ventilated area.
•
Work with approved safety equipment, such as those dust masks
that are specially designed to bag microscopic particles.
