any kickback force. Always use the auxiliary
handle, if included in the delivery, to ensure
optimum control over kickbacks or reaction
torques during start-up. The user can control
reaction torques or kickbacks if suitable pre-
cautionary measures are taken.
• Never place your hands near rotating tools.
Tools can kick back over your hand.
• Never position your body in the area in which
the machine moves in the event of a kickback.
A kickback accelerates the machine in the di-
rection of rotation opposed to the disc at the
jamming point.
• Take extra care when working in corners, on
sharp edges, etc. Avoid kickbacks and pre-
vent the tool from seizing. Corners, sharp
edges or a jump back tend to cause the ro-
tating tool to catch, thus leading to a loss of
control or a kickback.
Special safety instructions for fi ne sanding
• Do not use excessively large sanding discs
when fi ne sanding. Observe the specifi cati-
ons of the manufacturer when selecting abra-
sive discs. A sanding disc that is too large and
protrudes over the sanding pad represents a
cutting injury hazard and can cause catching,
disc tears or kickbacks.
Additional warning notes
• Hold the machine fi rmly with both hands and
assume a stable stance when performing
work. Hold the machine with both hands to
guide more securely.
• If potentially explosive or self-igniting dust is
produced during sanding, the processing in-
structions of the material manufacturer must
be observed under all circumstances.
• Harmful/toxic dusts can be produced during
your work (e.g. lead-containing paint, some
types of wood and metal). Contact with these
dusts, especially inhaling them, can represent
a hazard for operating personnel or persons
in the vicinity. Comply with the safety regula-
tions that apply in your country. Connect the
electric power tool to a suitable extraction
system. To protect your health, wear a protec-
tive mask.
• Never use machines with a damaged cable.
Do not touch damaged cables and pull the
plug from the mains power supply if the cable
becomes damaged during work. Damaged
cables increase the risk of electric shock.
ELECTRONICS
The machine features full-wave electronics with
the following properties:
Smooth start-up
The electronically controlled smooth start-up
function ensures that the machine starts up
smoothly.
8
Speed control
You can regulate the rotational speed steplessly
between 1500 and 2100 rpm using the adjusting
wheel. This enables you to optimise the cutting
speed to suit the respective material.
Constant speed
The preselected motor speed remains constant
through electronic control. This ensures a uni-
form cutting speed even when under strain.
CHANGING SANDING PADS
• Insert an Allen key into the Allen screw on the
sanding pad.
• Hold the sanding pad securely and turn the
Allen key to release.
In order to further ensure optimum axial run-
out, you must fi rst clean the bearing surface
for the grinding disk on the driveshaft.
• Attach the new sanding pad.
• Tighten the screw.
Only attach specifi ed sanding pads to the
machine.
AFFI XING ABRASIVES
Compatible sanding discs are quick and easy to
attach to the sanding pad. Simply press the self-
adhesive sanding discs onto the sanding pad.
The adhesive coating holds the sanding pad
securely in position. Make sure that the sanding
disc holes line up with the suction holes. Tear off
the sanding disc when worn.
ADJUSTING THE SUCTION POWER
You can adjust the suction power to match the
surface type, but only when internal extraction
is active.
• Use the adjusting wheel to adjust the suction
power.
• Start with a low suction power and slowly in-
crease until you can feel that the application
pressure has noticeably changed.
A high suction power makes sanding work on
ceilings and walls less tiring.
DUST EXTRACTION
CAUTION! Breathing in dust can dam-
age the respiratory passage!
• Always connect the machine to a dust extrac-
tor.
• When performing work that generates dust,
always wear a dust mask.
OPERATION
• Connect the machine to the mains power sup-
ply.
• Switch on the machine.
