Working instructions.
Before mounting or replacing application tools or accessories, pull the power
plug.
This preventive safety measure rules out the danger of injuries
through accidental starting of the power tool.
For each job, use only the FEIN application tool released and intended for the respec-
tive application.
Connecting the dust extraction
(Figure 2,
➐
).
When working materials that
produce dust, the power tool
is to be connected to an external dust extrac-
tion via the extraction adapter.
The vacuum cleaner must be suitable for
the material being worked.
When vacuuming dry dusts that are partic-
ularly hazardous to one’s health or carcino-
genic, a specialty vacuum cleaner is to be
used.
Switching ON and OFF (Figure 1).
First check that the power
cable and power plug are
not damaged.
Always hold the power tool
firmly.
Otherwise, you
could lose control over the power tool.
Switching ON:
➤
Push the switch towards the
front (
I
).
Switching OFF:
➤
Push the switch towards the
back (
0
).
Setting the oscillating frequency
(Figure 1).
The oscillating frequency can be set infi-
nitely variable with the dial control.
Increasing the oscillating frequency:
➤
Turn dial control in counterclock-
wise direction.
Decreasing the oscillating frequency:
➤
Turn dial control in clockwise direc-
tion.
The oscillating frequency depends on the
application and the application tool. Exam-
ple:
– High oscillating frequency:
Sanding, sawing, using as a rasp, polishing
stone and metal.
– Low oscillating frequency:
Polishing of varnish and veneers, removal
of grout, teak decks from boats.
Securing the work piece.
Secure the workpiece firmly.
A work piece that is gripped
tightly in a clamping device or vice, is more
secure than if held by hand.
Sanding
Typical application: Dry sanding of wood
and metal, especially of smaller surfaces,
corners and edges, as well as hard to reach
locations.
Work with the complete surface of the
sanding plate, not only with the tip. Select a
high oscillating frequency. Sand with con-
tinuous motion and light pressure.
Applying
excessive pressure does not increase mate-
rial removal; only the sanding sheet wears
more quickly.
Sawing
Typical application: Sawing of thin steel
sheet, wood and plastic components.
Select a high oscillating frequency.
