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
(GFCl) 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 jeweilery.
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,
ff
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) BATTERY TOOL USE AND CARE
a) 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.
b) Use power tools only with specifically designated battery packs.
Use of any other
battery packs may create a risk of injury and fire.
c) 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.
d) 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.
6) SERVICE
a) Have your power
tool serviced
by a quafified
repair
person
using only identical
replacement
parts. This will ensure that the safety of the power tool is maintained.
