Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 62841-2-4:
2 2
a = 5.0 m/s , K = 1.5 m/s ,
h
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
Selecting the Sanding Sheet
Different sanding sheets are available, depending on the material you are working with and the required surface removal rate:
Material
– Paint
– Varnish
– Filler
– Bodyfiller
Expert for Wood
– All wood and wood-based ma-
terials (e.g. hardwood, soft-
wood, chipboard, construction
boards)
Best for Wood
– Hardwood
– Chipboard
– Construction boards
– Metal materials
– Car paint
– Stone
– Marble
– Granite
– Ceramic
– Glass
– Perspex
– Fibreglass reinforced plastics
Changing the sanding sheet (see figure A)
To remove the sanding sheet (6), lift it from the side and pull
it from the sanding pad (5).

To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Application
For sanding down paint
For sanding undercoats (e.g. removing brush-
strokes, paint drips and paint runs)
For final sanding of primers prior to painting
For pre-sanding, e.g. of rough and uneven
beams and boards
For surface sanding and levelling of slight irreg-
ularities
For finish-sanding and fine sanding of wood
For pre-sanding
For shaping and edge chamfering
For fine sanding during shaping
Buffing and edge rounding
Remove dirt and dust from the sanding pad (5), e.g. with a
paintbrush, before attaching a new sanding sheet.
The surface of the sanding pad (5) is fitted with a hook-and-
loop fastening, allowing sanding sheets with a hook-and-loop
backing to be secured quickly and easily.
