Operation
5.1
Initial operation
Personnel entrusted to work with the machine must
be made aware of the operating instructions, calling
particular attention to the chapter "Safety
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 sander UVA 115 E can
be steplessly set at adjusting wheel 3 of the control
electronics from 4000 strokes/min to 24000
strokes/min.
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 working with the control electronics when
sanding a wide variety of different materials, you
always obtain a sanding speed that is suitable for the
material.
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.
