Do not use accessories which are not specifically
designed and recommended by the power tool manufac-
turer. Safe operation is not ensured merely because an
accessory fits your power tool.
Clean the ventilation openings on the power tool at regu-
lar intervals using non-metal tools. The blower of the
motor draws dust into the housing. An excessive accu-
mulation of metallic dust can cause an electrical hazard.
Before putting into operation, check the mains connec-
tion and the mains plug for damage.
Recommendation: The tool should always be supplied
with power via a residual current device (RCD) with a
rated current of 30 mA or less.
Handling hazardous dusts
For work procedures with this power tool where mate-
rial is removed, dusts develop that can be hazardous to
one's health.
Contact with or inhaling some dust types, e. g. asbestos
and asbestos-containing materials, lead-containing coat-
ings, metal, some wood types, minerals, silicate particles
from materials containing stone, paint solvents, wood
preservatives, antifouling paints for vessels, can trigger
allergic reactions to the operator or bystanders and/or
lead to respiratory infections, cancer, birth defects or
other reproductive harm. The risk from inhaling dusts
depends on the exposition. Use dust extraction matched
appropriately for the developing dust, as well as personal
protective equipment and provide for good ventilation of
the workplace. Leave the processing of asbestos-contain-
ing materials to specialists.
Wood and light-metal dust, hot mixtures of grinding dust
and chemical materials can self-ignite under unfavourable
conditions or cause an explosion. Avoid sparking in the
direction of the dust collector as well as overheating of
the power tool and the materials being sanded, empty the
dust collector/container in time, observe the material
manufacturer's working instructions, as well as the rele-
vant regulations in your country for the materials being
worked.
Hand/arm vibrations
The vibration emission level given in this information
sheet has been measured in accordance with a standard-
ised test given in EN 60745 and may be used to compare
one tool with another. It may be used for a preliminary
assessment of exposure.
The declared vibration emission level represents the
main applications of the tool. However, if the tool is used
for different applications, with different accessories or
poorly maintained, the vibration emission may differ.
This may significantly increase the exposure level over
the total working period.
An estimation of the level of exposure to vibration
should also take into account the times when the tool is
switched off or when it is running but not actually doing
the job. This may significantly reduce the exposure level
over the total working period.
Identify additional safety measures to protect the opera-
tor from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation
of work patterns.

Adjustments.
Before any work on the machine itself, pull the mains
plug.
Adjustment of the gap clearance (figures 1, 6).
Loosen screws (7) and adjust a max. gap clearance of
4 mm.
Tighten screws (7) again.
Adjusting the handle (figure 2).
The handle can be fastened in 3 different positions.
Loosen the handle.
Set the handle to your working position and retighten it.
Adjusting the belt tracking (figure 3).
Switch the machine on and check the belt tracking.
If the belt does not run centred, loosen screw (9) and
turn nut (10) using a spanner (size 10 mm) to the right or
left, as required.
Adjusting the working position of the drive motor
(figure 5).
Loosen the screw using a 6 mm Allen key and turn the
drive motor to the desired position.
The drive motor can be turned by 360°.
Replacing the grinding belt (figure 4).
Pivot lever (5) toward the right. The grinding belt is now
loose and can be removed.
Mount the new grinding belt. Pay attention that the arrow
directions on the inside of the grinding belt and the hous-
ing of the power tool correspond.
Pivot lever (5) toward the left and check if the grinding
belt is positioned centrally. Check the belt tracking regu-
larly.
Check the belt rollers for damage each time when replac-
ing a grinding belt. Replace damaged belt rollers.
Check the drive disc (13) and the contact disc (8) for
wear and damage each time when replacing a grinding
belt. Have damaged parts replaced.
