4.2.5 Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection, ear protection and pro-
tective gloves when the tool is in use. Breathing pro-
tection must be worn if no dust removal system is used.
5. Before use
It is essential that the safety precautions printed in these
operating instructions are read and observed.
The mains supply voltage must comply with the infor-
mation given on the type plate.
If extension cords are used: Only extension cords of a
type approved for the intended application may be used.
Check the extension cord and the supply cord for dam-
age at regular intervals.
Extension cords for outdoor use
For outdoor work use only extension cords approved
and correspondingly marked as suitable for outdoor use.
Pay attention at all times
Always concentrate on the job. Proceed carefully and
do not use the tool if you are distracted from your work.
6. Operation
System
The sanding finish and speed of material removal is
determined by the choice of sanding sheet (grit), the
speed setting and the pressure applied to the sander.
The electric tool, the sanding plate and the sanding sheet
form a system. Take care to ensure that the most suit-
able combination and tool settings are used for the appli-
cation.
Fitting sanding sheets
Use sanding sheets with an outside diameter of 150 mm
and Velcro-type attachment.
Sanding sheets with 6 dust extraction holes (80 mm
pitch circle diameter) or 9 holes (8 holes on 120 mm
pitch circle and 1 hole in the centre of the sheet) may be
used.
●
Prevent unintentional starting by disconnecting the
supply cord plug from the mains socket.
●
Take care to ensure that the dust extraction holes in
the sanding sheet are in alignment with the holes in the
sanding plate.
Holding the sander - recommended grip positions
For fast removal
●
Guide the tool with both hands.
●
Use the main grip and the built-in auxiliary grip. Pull
the auxiliary grip out into the working position (the guid-
ing grip may be used instead of the auxiliary grip).
For finishing work
●
Guide the tool with one hand.
●
Use the finishing grip. This makes it possible to guide
the tool precisely and easily with 1 hand close to the sur-
face being sanded and ensures a sensitive touch, for
example, for intermediate sanding between coats of paint
or fine finishing sanding.
For working on vertical surfaces
(e.g. walls, edges, etc.)
●
Guide the tool by the finishing grip. The centre of bal-
ance of the tool then lies in the hand when working on
vertical surfaces. This makes it possible to work safely
and without undue fatigue.
CAUTION
Sanding may produce hazardous sanding dust.
Sanding dust may be harmful to the lungs and eyes.
Use a dust extraction system and wear respiratory pro-
tection and protective goggles.
Sanding
●
Ensure that the tool is switched off.
●
Connect the supply cord plug to the mains socket.
●
Select the desired speed.
●
Place the tool on the workpiece, ensuring that the
entire sanding surface is in contact.
●
Switch on the tool and move it over the workpiece
while applying moderate pressure (approx. 20 N).
●
When you are finished working or during pauses
between work, we recommend that the tool is lifted away
from the workpiece while running and then switched off.
