Vibration

The vibration total value (tri-axial vector sum) deter-
mined according to EN62841-2-1:
Work mode: drilling into metal
Vibration emission (a

h,D

) : 2.5 m/s

2

 or less

Uncertainty (K) : 1.5 m/s

2

NOTE:

 The declared vibration total value(s) has been 

measured in accordance with a standard test method 
and may be used for comparing one tool with another.

NOTE:

 The declared vibration total value(s) may also 

be used in a preliminary assessment of exposure.

WARNING:

 

The vibration emission during actual 

use of the power tool can differ from the declared val

-

ue(s) depending on the ways in which the tool is used 
especially what kind of workpiece is processed.

WARNING:

 

Be sure to identify safety measures 

to protect the operator that are based on an estima-
tion of exposure in the actual conditions of use (tak-
ing account of all parts of the operating cycle such 

as the times when the tool is switched off and when 

it is running idle in addition to the trigger time).

EC Declaration of Conformity

For European countries only

The EC declaration of conformity is included as Annex A 
to this instruction manual.

SAFETY WARNINGS

General power tool safety warnings

WARNING:

 

Read all safety warnings, instruc-

tions, illustrations and specifications provided with this 

power tool.

 Failure to follow all instructions listed below 

may result in electric shock, fire and/or serious injury.

Save all warnings and instruc-
tions 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. 

Keep work area clean and well lit.

 Cluttered or 

dark areas invite accidents.

2. 

Do not operate power tools in explosive atmo-

spheres, such as in the presence of flammable 

liquids, gases or dust.

 Power tools create sparks 

which may ignite the dust or fumes.

3. 

Keep children and bystanders away while operating 
a power tool.

 Distractions can cause you to lose control.

Electrical safety

1. 

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.

2. 

Avoid body contact with earthed or grounded 
surfaces, such as pipes, radiators, ranges and 
refrigerators.

 There is an increased risk of elec-

tric shock if your body is earthed or grounded.

3. 

Do not expose power tools to rain or wet con-
ditions.

 Water entering a power tool will increase 

the risk of electric shock.

4. 

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.

5. 

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.

6. 

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.

7. 

Power tools can produce electromagnetic 

fields (EMF) that are not harmful to the user.

 

However, users of pacemakers and other similar 
medical devices should contact the maker of their 
device and/or doctor for advice before operating 
this power tool.

Personal safety

1. 

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 med

-

ication.

 A moment of inattention while operating 

power tools may result in serious personal injury.

2. 

Use personal protective equipment. Always 
wear eye protection.

 Protective equipment such 

as a dust mask, non-skid safety shoes, hard hat or 
hearing protection used for appropriate conditions 

will reduce personal injuries.

3. 

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.

4. 

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.

5. 

Do not overreach. Keep proper footing and 
balance at all times.

 This enables better control 

of the power tool in unexpected situations.

6. 

Dress properly. Do not wear loose clothing or 
jewellery. Keep your hair and clothing away 
from moving parts.

 Loose clothes, jewellery or 

long hair can be caught in moving parts.

7. 

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.

8. 

Do not let familiarity gained from frequent use 
of tools allow you to become complacent and 
ignore tool safety principles.

 A careless action 

can cause severe injury within a fraction of a 

second.
