Power
Tool Safety
Warnings
_
ARNING! 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.
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or 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) ff operating
a power tool in a damp location
is unavoidable,
use a ground fault circuit
interrupter (GFCI) protected supply, Use of a GFCI 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 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.
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) ff 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 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.
5) SERVICE
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
Rules
for Hammerdrills
•
Wear ear protectors
with impact drills. Exposure to noise can cause hearing loss.
•
Use auxiliary
handles supplied
with the tooL Loss of control can cause personal injury.
•
Hold power
tools
by insulated
gripping
surfaces
when performing
an operation
where the cutting
tool may contact
hidden wiring or its own cord. Contact with a "live"
wire will make exposed metal parts of the tool "live" and shock the operator.
•
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
•
Wear ear protectors
when hammering
for extented periods
of time. Prolonged exposure
to high intensity noise can cause hearing loss. Temporary hearing loss or serious ear drum
damage may result from high sound levels generated by hammer drilling.
•
Wear safety goggles
or other eye protection.
Hammering and drilling operations cause
chips to fly,Flying particles can cause permanent eye damage. Wear a dust mask or respirator
for applications that generate dust. Ear protection may be required for most applications.
• Always
use the side handle supplied
with the tooL Tighten the side handle securely
before use. Keep a firm grip on the tool at all times. Do not attempt to operate this tool
without
holding
it with both hands. Operating this tool with one hand will result in loss of
control Breaking through or encountering hard materials such as re-bar may be hazardous
as well.
•
Hammer bits and tools get hot during operation.
Wear gloves when touching them.
•
Do not operate this tool for long periods
of time. Vibration caused by hammer action may
be harmful to your hands and arms. Use gloves to provide extra cushion and limit exposure
by taking frequent rest periods.
• Air vents often cover moving parts and should
be avoided.
Loose clothes, jewellery or
long hair can be caught in moving parts.
• An extension
cord must have adequate
wire size (AWG or American
Wire Gauge) for
safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that
is 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. When using more than one extension to
make up the total length, be sure each individual extension contains at least the minimum
wire size. The following table shows the correct size to use depending on cord length and
nameplate ampere rating, ff in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
