Noise/Vibration Information

Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 81 dB(A); Sound power level 91 dB(A).
Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745:

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 expo-
sure.
The declared vibration emission level represents the main ap-
plications 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 significantly in-
crease 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 sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep hands warm, organise work patterns.

Assembly
Changing the Tool
Before any work on the machine itself, pull the mains
plug.
Open the key type drill chuck 5 by turning until the tool can be
inserted. Insert the tool.
Insert the chuck key 3 into the corresponding holes of the key
type drill chuck 5 and clamp the tool uniformly.

Screwdriver Tools
When working with screwdriver bits , a universal bit holder
should always be used. Use only screwdriver bits that fit the
screw head.
Dust/Chip Extraction
Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause

,
allergic reactions and/or lead to respiratory infections of

.
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Operation
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Reversing the rotational direction
Actuate the rotational direction switch 1 only when the
machine is at a standstill.
The rotational direction switch 1 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 4 actuated.
Right rotation: For drilling and driving in screws, push the ro-
tational direction switch 1 to "R".
Left rotation: For loosening or unscrewing screws and nuts,
push the rotational direction switch 1 to "L".
Switching On and Off
O
O
To switch off the machine, release the On/Off switch 4. When
the On/Off switch 4 is locked, press it first and then release it.
When not using the power tool, switch it off in order to save
energy.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 4 is pressed.
Light pressure on the On/Off switch 4 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
To start the machine, firstly pull the
I
On/Off switch 4 toward the rear and then
press the On/Off switch 4.
To lock-on, pull the On/Off switch 4 to-
I F
ward the rear, press the On/Off switch 4
and pull it further toward the rear.
