Cordless Random Orbital Sander

Press the sanding sheet firmly onto the un-
derside of the sanding pad.
To ensure optimum dust extraction, make
sure that the punched holes in the sanding
sheet are aligned with the drilled holes in the
sanding pad.
Selection of the Sanding Plate
The power tool can be fitted with sanding
pads of various hardnesses, depending on
the application:
– Extra soft sanding pad: Suitable for
polishing and sensitive sanding even on
curved surfaces.
– Soft sanding pad: Suitable for all sanding
work, universal application.
– Hard sanding pad: Suitable for heavy
sanding on fl at surfaces.
Changing the sanding pad (see fi gure B)
Note:
Replace damaged sanding pads imme-
diately.
Remove the sanding sheet or polishing tool.
Unscrew the screw completely and remove
the sanding pad. Attach the new sanding
pad and retighten the screw so that it is fin-
ger-tight.
Note: Pads with diameters of 150 mm and
125 mm have diff erent carriers. The pads can
only be fi tted to the right power tool.
Note:
When attaching the sanding pad, make
sure that the teeth of the catch mate with the
recesses in the sanding pad.
Note: Damaged sanding pads must only be
replaced by an after-sales service centre au-
thorised to work with P.I.T. power tools.
Dust/chip extraction
The dust from materials such as lead paint,
some types of wood, minerals and metal can
be harmful to human health.
Touching or breathing in this dust can trigger
allergic reactions and/or cause respiratory
illnesses in the user or in people in the near
vicinity.
Certain dusts, such as oak or beech dust,
are classified as carcinogenic, especially in
conjunction with wood treatment additives
(chromate, wood preservative). Materials con-
taining asbestos may only be machined by
specialists.
– Use a dust extraction system that is suit-
able for the material wherever possible.
– Provide good ventilation at the work-
place.
– It is advisable to wear a P2 filter class
breathing mask.
The regulations on the material being ma-
chined that apply in the country of use must
be observed.
► Avoid dust accumulation at the work-
place. Dust can easily ignite.
External dust extraction (see fi gure C)
Attach the dust extraction adapter to the
extraction outlet. Make sure that the locking
levers of the dust extraction adapter lock into
place.
The dust extractor must be suitable for the
material being worked.
When extracting dry dust that is especially
detrimental to health or carcinogenic, use a
special dust extractor.
When working on vertical surfaces, hold the
power tool with the dust extraction hose fac-
ing downwards.
Operation
Starting Operation
► Pay attention to the mains voltage. The
voltage of the power source must match
the voltage specifi ed on the rating plate of
the power tool. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
► Make sure that you are able to press the
On/Off switch without releasing the handle.
To switch on the power tool, press and hold
the on/off switch.
To lock the on/off switch press and hold it
while also pushing the lock-on button.
To switch off the power tool, release the on/off
switch. If the on/off switch is locked, press the
switch fi rst and then release it.
Preselecting the orbital stroke rate
You can even preselect the orbital stroke rate
during operation using the necessary orbital
stroke rate preselection thumbwheel.
The required orbital stroke rate is dependent
on the material and the work conditions and
can be determined using practical tests.
The Constant Electronic keeps the orbital
stroke rate at no load and under load virtually
consistent, guaranteeing uniform perfor-
mance.
After working at a low orbital stoke rate for
an extended period, you should operate the
power tool at the maximum orbital stroke rate
for approximately three minutes without load
to cool it down.
Sanding Plate Brake
An integrated sanding pad brake reduces the
orbital stroke rate when running without load
to prevent scoring when the power tool is
placed on the workpiece.
