CLASS 1 LED PRODUCT
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, re 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
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
adaptor 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.
If operating power tools 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 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.
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

2
turn it on and off. Any power tool that can not 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
tools 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 and in 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 different from intended could result in a
hazardous situation.
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.
DRILL AND SCREWDRIVER SAFETY WARNINGS
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.
Hold power tool by insulated gripping surfaces,
when performing an operation where the fasteners
may contact hidden wiring. Fasteners contacting a
“live” wire may make exposed metal parts of the power
tool “live” and could give the operator an electric shock.
CHARGER SAFETY WARNINGS
Do not expose charger to wet or damp conditions.
Use of an attachment not recommended or sold by the
battery charger manufacturer may result in a risk of
fire, electric shock, or injuries to person.
To reduce risk of damage to charger body and
cord, pull by charger plug rather than cord when
disconnecting charger.
Make sure cord is located so that it will not be stepped
on, tripped over, or otherwise subjected to damage
and stress.
An extension cord should not be used unless
absolutely necessary. Use of improper extension
cord could result in a risk of fire and electric shock. If
extension cord must be used, make sure:
a. That pins on plug of extension cord are the same
number, size and shape as those of plug on charger.
b. That extension cord is properly wired and in good
electrical condition.
Do not operate charger with a damaged cord or plug,
which could cause shorting and electric shock. If
damaged, have the charger replaced by an authorised
serviceman.
Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way; take
it to a qualified serviceman.
Do not disassemble charger; take it to a qualified
serviceman when service or repair is required.
Incorrect reassembly may result in a risk of electric
shock or fire.
To reduce risk of electric shock, unplug the charger
from outlet before attempting any maintenance or
cleaning. Turning off controls will not reduce this risk.
Disconnect charger from power supply when not in
use.
Risk of electric shock. Do not touch uninsulated portion
of output connector or uninsulated battery terminal.

VIBRATION LEVEL
WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of
exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is used
for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may
signicantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may signicantly reduce the exposure level over the total working
period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation of work patterns.
