en

When only one tip or corner of the sanding sheet is 
worn, it can be removed again and reattached turned by 
120°.
Work with the entire surface of the sanding plate, not 
only with the tip.
When sanding with small triangle sanding plates, select 
a high oscillating frequency (electronics level 4 – 6); 
when sanding with the round sanding plate and the 
large triangle sanding plate, select a moderate oscillating 
frequency (max. electronics level 4).
Sand with continuous motion applying moderate pres-
sure. Applying excessive pressure does not increase the 
rate of removal, it only wears off the sanding sheet 
faster.

Notes on profile sanding.

Select a medium oscillating frequency.

Notes on sawing.

Select a high oscillating frequency. Round saw blades 
can be released and clamped offset again, to allow for 
uniform wearing off.

Notes on scraping.

Select a moderate to high oscillating frequency.

Repair and customer service.

When working metal under extreme oper-
ating conditions, it is possible for conductive 
dust to settle in the interior of the power 

tool. The total insulation of the power tool can be 
impaired. Blow out the interior of the power tool via 
the ventilation slots frequently with dry and oil-free 
compressed air, and connect a residual current device 
(RCD) on the line side.
When working gypsum-containing materials, dust can 
settle within the power tool and switch element, which 
can harden in connection with humidity. This can 
impair the switching mechanism. Blow out the interior 
of the power tool via the ventilation slots and the 
switch element frequently with dry and oil-free com-
pressed air.
Products that have come into contact with asbestos 
may not be sent in for repair. Dispose of products con-
taminated with asbestos according to the applicable 
country-specific regulations for such disposal.
When the machine's power supply cord is damaged, it 
must be replaced by the manufacturer or their repre-
sentative.
