In case of extreme dust deposits, the machine
cleaning cycles must be shortened and/or a
residual-current-operated circuit-breaker (RCCB)
must be connected upstream.
When the machine is shut down via the RCCB
circuit-breaker, it must be checked and cleaned.
Use only cutting discs recommended by the
manufacturer that comply with the specifications of
the respective safety standards for grinding
materials, e.g. EN 12413.
Caution! The use of other tools and accessories can
result in a risk of injury.
Cutting discs must be stored in accordance with
manufacturer specifications and handled carefully.
Wear protective gloves when handling cut-off
wheels.
Store the cutting disc in a dry place. With cutting
discs for dry cuts, the strength may be reduced by
moisture or water.
Handle the cutting disc with caution. Protect the
cutting disc from jolts or impacts.
Always use equipment that fulfils the following
minimum requirements:
Only cutting discs with resinoid bonding and fibre
reinforcement can be used. The maximum rotations
per minute (rpm) of the cutting disc must not be
lower than the machine idling speed.
Adhere to the maximum cutting disc diameter (see
technical data).
Use no cutting discs that are thicker than 3 mm (3/
32").
The bore of the cutting disc must fit the toolholder
without any clearance. Do not use adapters or
reducers.
Observe the specifications of the tool or accessory
manufacturer!
Adhere to the cutting disc instruction manual.
Use elastic cushioning layers if they have been
supplied with the sanding media and if required.
Be particularly cautious with the parts that are
connected to the cutting disc. Take care not to
damage the spindle, flange or screw. Damage to
these parts can cause the cutting disc to break.
It must be ensured that mounted cutting discs are
installed in accordance with the manufacturer
specifications.
Before use, make sure the cutting discs are
correctly fixed and fastened, and operate the
machine in idling mode for 30 s. Immediately switch
off the machine if strong vibrations or other
malfunctions occur. Should they occur, inspect the
machine to find the cause.
When the cutting disc is used up to the wear limit (1/
3 of the outer diameter), replace the cutting disc.
Pull the plug out of the plug socket before any
adjustments or servicing are performed.
The cutting disc continues to rotate after the
machine has been switched off.
Engage the spindle locking knob (8) only when the
motor is inoperative.
Do not touch the rotating cutting disc.
Danger of injury!
When the cutting disc vibrates too strongly in idling
mode, it can lead to breakage. In case of
irregularities during use, immediately switch off the
machine and have it repaired.
Secure the workpiece. Use the vice to secure the
workpiece.
Do not try to saw extremely small workpieces.
During machining, the workpiece must be firmly
supported and secured against moving.
Long workpieces must be sufficiently supported.
Begin cutting only after having reached the max.
rpm.
Use only the cutting edge of the cutting disc to cut.
Do not use the lateral surface of the cutting disc for
grinding jobs.
When working on workpieces with curves or
inclined surfaces, make sure that no lateral
pressure is applied to the cutting disc.
Ensure that sparks produced during work do not
constitute a risk to the user or other personnel and
are not able to ignite inflammable substances.
Endangered areas must be protected with flame-
resistant covers.
Make sure that fire-risk areas are always provided
with suitable fire extinguishers.
The workpiece can be very hot after having been
machined. Caution, risk of burning!
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).
