WARNING:

 

Wear ear protection.

WARNING:

 

The noise emission during actual 

use of the power tool can differ from the declared 

value(s) depending on the ways in which the 

tool is used especially what kind of workpiece is 

processed.

WARNING:

 

Be sure to identify safety mea-

sures to protect the operator that are based on an 

estimation of exposure in the actual conditions of 

use (taking 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).

Vibration

The vibration total value (tri-axial vector sum) deter-

mined according to EN62841-2-2:

Model DTW300

Work mode: impact tightening of fasteners of the maxi-

mum capacity of the tool

Vibration emission (a

h

) : 12.5 m/s

2

Uncertainty (K) : 1.5 m/s

Model DTW301

Work mode: impact tightening of fasteners of the maxi-

mum capacity of the tool

Vibration emission (a

h

) : 12.5 m/s

2

Uncertainty (K) : 1.5 m/s

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 value(s) depending on the ways in which 

the tool is used especially what kind of workpiece 

is processed.

WARNING:

 

Be sure to identify safety mea-

sures to protect the operator that are based on an 

estimation of exposure in the actual conditions of 

use (taking 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

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.
