Machine-related instructions
This machine is designed for grinding. Please read all safety notices, instructions, illustrations
and descriptions supplied with the machine. Failure to follow the instructions below could res-
ult in electric shock, fire, and/or serious injury.
Do not use this machine for jobs such as scrubbing, brushing, polishing, or disc grinding. Per-
forming tasks for which the machine was not designed can lead to danger and injuries.
Never use accessories that are not specifically designed and intended for this machine. Safe
operation is not automatically guaranteed just because an accessory can be attached to your
machine.
The permissible speed of the accessories must be at least as high as the maximum speed
specified on the machine. ccessories that rotate faster than the permitted speed can break.
The outside diameter and thickness of the accessories must be within the specified size range
of the machine. ccessories with incorrect dimensions cannot be adequately protected or con-
trolled.
The bore diameter of washers, flanges, retaining plates and all other accessories must fit ex-
actly on the machine spindle. ccessories with an unsuitable diameter run out-of-round, vi-
brate heavily and lead to loss of control.
Do not use damaged accessories. Before each use, check the accessories, e.Jg. abrasive
pads, nicks or kinks and backing plates for cracks and excessive wear. Every time the ma-
chine has been dropped, check whether the machine and the accessories are damaged and,
if necessary, mount undamaged accessories. fter checking and installing the accessories,
ensure that everyone is out of the rotating range of the tool and allow the machine to run at
maximum speed for one minute. Damaged accessories usually break through completely dur-
ing this test run.

Wear personal protective equipment. Use shielding or safety glasses depending on the applic-
ation. If possible, wear a respirator, ear protection, protective gloves and a work apron that is
suitable for protecting against bumps or small grinding or workpiece parts. The respirator or
device must be able to filter particles caused by various work processes. Constant exposure
to noise can lead to hearing loss.
Make sure that people in the vicinity of the machine are a safe distance from the work area. ll
persons in the work area must wear personal protective equipment. Parts of the workpiece or
broken accessories can fly off and cause injuries outside the immediate work area.
lways hold the machine by the insulated handles when you want to carry out work that in-
volves the risk of intruding into hidden power cables or your own machine cable. Contact with
live cables transmits an electric current to metallic machine parts and causes electric shocks.
Keep the power cord away from rotating parts. If you lose control, the power cord could be cut
or caught, which could pull your hand or arm into rotating parts.
Never stop the machine until the tool has come to a complete standstill. Lathe tools can get
caught on the work surface, causing you to lose control of the machine.
Make sure that the machine never operates while you are carrying it by your side. The rotating
tool can accidentally catch your clothing and cause serious cuts.
Clean the ventilation slots on your machine regularly. The cooling air fan draws the dust into
the machine and excessive build-up of metal dust can create electrical hazards.
Never operate the machine in the vicinity of explosive materials. Sparks could set them on fire.
Never use tools that require liquid cooling. Water and other liquid coolants can cause poten-
tially fatal electric shock.

Kickback causes and how to avoid kickback
Kickback is a sudden reaction to the pinching or catching of a spinning disc, platen, brush, or
other accessory.
The pinching or entanglement causes the rotating accessory to come to a rapid standstill, with
a counter-reaction accelerating an out of control machine around the pinching point, which in
turn drives out the disc. Depending on the direction of rotation, the disc can either fly towards
the user or away from the user. It can also break the sanding pad. Kickback is the result of in-
correct use of the machine and/or incorrect work or operation and can be avoided by carefully
observing the following precautionary measures.
lways hold the machine firmly and position your body and arms so that you can control all
kickback forces. lways use the auxiliary handle, if included in the scope of delivery, in order
to ensure optimal control of kickbacks or reaction moments during commissioning. The user
can control reaction moments or kickbacks if appropriate precautionary measures are taken.
Keep your hands away from moving parts. The device could jump back and hit your hand.
Never position your body in the area where the machine will move in the event of a kickback.
kickback accelerates the machine in the direction of rotation opposite the disc at the clamp-
ing point.
Be particularly careful when working in corners, on sharp edges, etc. void kickbacks and pre-
vent the tool from getting stuck. Corners and sharp edges can cause the rotating tool to get
caught, resulting in loss of control or kickback.
Special safety instructions for fine sanding
Do not use grinding discs that are too large for fine sanding. The manufacturer’s instructions must be
observed when selecting the grinding discs. grinding disc that is too large and protrudes beyond the
sanding pad poses a risk of cuts and can lead to entanglement, cracks and kickbacks.
Additional warnings
Hold the machine firmly with both hands and maintain a stable posture when working. Hold
the machine with both hands to ensure safe guidance.
If explosive or self-igniting dust is produced during sanding, the processing instructions of the
material manufacturer must be observed.

During work, harmful/toxic dusts can arise (e.Jg. from leaded paints, some types of wood and
metal). Contact with these dusts, especially inhalation, can pose a risk to the operator or to
people in the vicinity. Observe the safety regulations applicable in your country. Connect the
power tool to a suitable extraction system. Wear a protective mask to protect your health.
Never use devices if their power cord is damaged. Do not touch damaged cables and discon -
nect the power plug from the mains if the cable is damaged during work. Damaged cables in-
crease the risk of electric shock.
Commissioning
Warning! Danger of accidents when operating the machine with impermissible voltages or
frequencies.
The mains voltage and the frequency of the power source must correspond to the specification on the
nameplate of the machine.
Asse bling the grinding device
Hold the grinding head (1-1) with the grinding plate facing down.
When the handle is the desired length, lock the lock button (3-1)
Extend the tube (1-3), insert the handle (1-2) and then lock it (3-2)
Connect the suction pipe (6-2) to the dust outlet nozzle (6-1) and the other side to (6-3) If you
wish, you can also use the grinder to sand walls where space is limited. You can e.Jg. reduce
the length of the machine by adjusting the extension tubes (1-3)
Electronics
The machine has the following properties:
Smooth start-up
The electronically controlled soft start ensures that the machine starts smoothly.
Controlled speed
The speed can be regulated with the adjusting wheel (2-2) In this way you can adjust the cut-
ting speed to the respective material.
Permanent speed
The preselected engine speed remains constant thanks to the electronic control. This ensures
a constant cutting speed even under load.
Changing the sanding pad
Insert a key (size 5) into the screw (4-1) of the sanding pad.
Hold the sanding pad firmly and turn the key to loosen it. In order to ensure an optimal axial
run-out, you must first clean the contact surface for the grinding wheel on the drive shaft.
ttach the new sanding pad.
Tighten the screws (4-1) again.
Only attach the intended sanding pads to the machine. In order to ensure optimum suction perform -
ances, the sealing surface between the machine and the sanding pad is ground in in the first few
minutes after changing the disc. During this time, the speed of the machine is slightly lower and forms
particles from the grinding process. However, they do not damage the machine.
Attaching abrasives
Grinding discs can be quickly and easily attached to the sanding pad. Simply press the self-adhesive
grinding discs (4-2) onto the sanding pad. The adhesive coating holds the grinding wheel securely in
place. Make sure that the holes in the grinding wheels line up with the suction holes (4-3) Tear off the
grinding disc when worn.
