Initial Operation - Metabo SB 850-2 Original Instructions Manual

en ENGLISH
This also applies to dust from other materials such
as some timber types (like oak or beech dust),
metals, asbestos. Other known diseases are e.g.
allergic reactions, respiratory diseases. Do not let
dust enter the body.
Observe the relevant guidelines and national
regulations for your material, staff, application and
place of application (e.g. occupational health and
safety regulations, disposal).
Collect the particles generated at the source, avoid
deposits in the surrounding area.
Use suitable accessories for special work. In this
way, fewer particles enter the environment in an
uncontrolled manner.
Use a suitable extraction unit.
Reduce dust exposure with the following measures:
- do not direct the escaping particles and the
exhaust air stream at yourself or nearby persons
or on dust deposits,
- use an extraction unit and/or air purifiers,
- ensure good ventilation of the workplace and keep
clean using a vacuum cleaner. Sweeping or
blowing stirs up dust.
- Vacuum or wash the protective clothing. Do not
blow, beat or brush.

7. Initial Operation

Before plugging in the device, check to see
that the rated mains voltage and mains
frequency, as specified on the rating label, match
your power supply.
Always install an RCD with a maximum trip
current of 30 mA upstream.
To guarantee secure purchase of the chuck:
After initial drilling (clockwise), use a screw-
driver to firmly tighten the safety screw inside the
drill chuck (if available/depending on the model).
THE SAFETY SCREW HAS A LEFT-HANDED
THREAD!
7.1 Fitting the additional handle (2)
B
For safety reasons, always use the additional
handle supplied.
Tighten the additional handle firmly by turning it.
8. Use
8.1 Setting depth stop
8.2 Setting direction of rotation, transporting
safety device (switch-on lock)
Do not activate the rotation selector switch
(11) unless the motor has completely stopped.
8.3 Setting for normal drilling, impact drilling
Fig. E
Impact drilling and normal drilling only in a
clockwise direction.
8.4 Selecting gear
Change thumbwheel (1) only when the
machine is in the process of running down
(briefly switch it on and off).
8.5 Setting impulse function
= impulse function switched on constantly (to
facilitate tightening and releasing of screws
that are tight even when the screw heads are
damaged. To enable clean drilling without
centre punching in tiles, aluminium or other
materials).
8.6 Preselecting rotational speed
See the table for recommended rotational speeds
for drilling.
8.7 Switching On and Off
Switching on, rotational speed
the trigger (13).
Release the trigger to switch off.
Continuous operation
(13) pressed, push in the locking button (12) and
release the trigger. Press and release the trigger
