Grinding disk brake
To prevent an unchecked raising of the grinding disk,
it is braked by a sleeve 9 (Fig. 5). As the sleeve
wears out in the course of time, it must be replaced
with a new one at a MAFELL customer service shop if
the braking effect decreases.
4.5 Additional handle
If necessary, the additional handle 10 (Fig. 6) can be
dismantled from the machine with the integrated
screw 11 using the enclosed hexagon screw driver.
4.6 edge protection
The edge protection 12 (Fig. 6) can be detached from
the machine, if necessary. To do so, turn it to the left
into its rear position, then push downwards and pull
out to the rear.

Operation
5.1 Initial operation
Personnel entrusted to work with the machine must
be made aware of the operating instructions, calling
particular
attention
instructions".
5.2 Switching on and off
Short operation
Switching on: Press switch 1 (Fig.1).
Switching off: Release the switch.
Continuous operation
Switching on: Press switch 1 and locking
button 2 consecutively. Then release the switch
with depressed locking button. The motor runs
without pressure on the switch.
Switching off: Press switch 1 until locking
button 2 pops out. Then release the switch.
5.3 Control electronics
The stroke rate of the orbital disk sander EVA150E 3
/ EVA150E 5 can be adjusted in a continuously

the
chapter
"Safety
variable manner between 9000 strokes/min and
22000 strokes/min at the adjusting wheel 3 (Fig.1) of
the control electronics .
With the control electronics, the sanding speed can
be adapted to the respective material. Thus, heat-
sensitive materials such as plastics, paints, varnishes
and glazes are protected against damage by
excessive sanding speeds. In addition, the abrasive
grid lasts longer as it does not get clogged. Thus,
when grinding different materials, always use the
control electronics to select a grinding speed that is
appropriate for the material to be processed.
5.4 Work instructions
The best sanding performance is achieved with slight
pressure.
You can avoid scratching caused by switching on and
off, if you position the running orbital sander on the
workpiece and also remove it with running motor from
the workpiece.

Service and maintenance
Danger
Pull the power plug during all
service work.
MAFELL machines are designed to be low in
maintenance.
The ball bearings used are greased for life. When the
machine has been in operation for a longer period of
time, we recommend to hand the machine in at an
authorised MAFELL customer service shop for
inspection.
Regularly remove deposited dust from the machine.
In the process, blow out the ventilation openings on
the motor.
6.1 Storage
If the machine is not used for a longer period of time,
it has to be carefully cleaned. Spray bright metal parts
with a rust inhibitor.
