VIBRATION INFORMATION

Vibration total values (triax vector sum) determined according to EN 60745:

Typical weighted vibration

The declared vibration total value may be used for comparing one tool with another, and may
also be used in a preliminary assessment of exposure.

WARNING: The vibration emission value during actual use of the power tool can differ

from the declared value depending on the ways in which the tool is used dependant on
the following examples and other variations on how the tool is used:
How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained .
The use the correct accessory for the tool and ensuring it is sharp and in good condition.
The tightness of the grip on the handles and if any anti vibration accessories are used.
And the tool is being used as intended by its design and these instructions.

Vibration emission value ah= 9.37m/s

Uncertainty K = 1.5m/s²

2

5

This tool may cause hand-arm vibration syndrome if its use is not adequately
managed.

WARNING: To be accurate, an estimation of exposure level in the actual conditions of

use should also take account of all parts of the operating cycle such as the times when
the tool is switched off and when it is running idle but not actually doing the job. This may
significantly reduce the exposure level over the total working period.

Helping to minimise your vibration exposure risk.
ALWAYS use sharp chisels, drills and blades.
Maintain this tool in accordance with these instructions and keep well lubricated (where
appropriate).
If the tool is to be used regularly then invest in anti vibration accessories.
Avoid using tools in temperatures of 10°C or less.
Plan your work schedule to spread any high vibration tool use across a number of days.

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.

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.

6

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.

b) Use personal protective equipment.

Always wear eye protection. Protective

equipment such as dust mask, non­skid 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)

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.

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) 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 qualified repair person using only
identical replacement parts. This will

ensure that the safety of the power tool is
maintained.

SCREW DRIVER AND
IMPACT WRENCH SAFETY
WARNING

1. Hold power tool by insulated gripping
surfaces, when performing an operation
where the fastener 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.
