When using dual-purpose (combined grinding and
cut-off wheels), only the following guard types must
be used: type A, type C.
See chapter 11.
Using the correct guard:
Using an incorrect guard can lead to loss of control
and serious injuries. Examples for incorrect use:
- when using a type A guard for lateral grinding, the
guard may interfere with the workpiece causing
poor control.
- when using a type B guard for cutting-off
operations with bonded cut-off wheels, there is an
increased risk of exposure to emitted sparks and
particles, as well as exposure to wheel fragments
in the event of a wheel burst.
- when using a type A, B, C guard for cutting-off
operations or lateral grinding in concrete or
masonry, there is an increased risk of exposure to
dust and loss of control resulting in kickback.
- when using a type A, B, C guard with a wheel-type
wire brush with a thickness greater than the
maximum permitted thickness, the wires may
catch on the guard leading to breaking of the
wires.
Always use the matching guard for the accessory.
See chapter 11.
Reducing dust exposure:
WARNING - Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
- Lead from lead-based paints,
- crystalline silica from bricks and cement and other
masonry products, and
- arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals,work in a well-
ventilated area, and work with approved safety
equipment, such as those dust masks that are
specially designed to filter out microscopic
particles.
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 towards yourself or nearby
persons or towards dust deposits,
- use an extraction unit and/or an air purifier,
16
- ensure good ventilation of the workplace and keep
it clean using a vacuum cleaner. Sweeping or
blowing stirs up dust.
- Vacuum or wash protective clothing. Do not blow,
beat or brush protective gear.

6. Commissioning
Before commissioning, check that the rated
mains voltage and mains frequency stated on
the type plate match your power supply.
Always install an upstream GFCI with a
maximum trip current of 30 mA.
6.1 Attaching the additional handle
Always work with the additional handle (10)
attached! Attach the additional handle on the
left or right of the machine and secure.
6.2 Attach the safety guard
For safety reasons, only use the guard
provided for the respective accessory! Using
an incorrect guard can lead to loss of control and
serious injuries. See also chapter 11. Accessories!
