USE
• Assembly instructions ⑦
- unfold the tool and ensure that screw A fits the slot in
the tool handle connection
- push down lever B completely for locking the handle
connection
! if necessary, use hex key C for loosening/
tightening screw A when handle connection
cannot be locked completely
- for folding the tool handle vice-versa
Extending tool to medium length (165 cm) ⑧
•
- loosen locking sleeve D by turning it in the direction of
the unlocking symbol on the tool
- extend the tool to the desired length (123 - 165 cm)
- tighten locking sleeve D by turning it in the direction of
the locking symbol on the tool
• Extending tool to maximum length (220 cm) ⑨
- loosen locking sleeve E by turning it in the direction of
the unlocking symbol on the tool handle
- insert additional handle F into the end of the tool
handle until the marking as illustrated aligns with the
edge of locking sleeve E
- tighten locking sleeve E by turning it in the direction of
the locking symbol on the tool handle
! extending the tool to its maximum length is only
possible when tool is already extended to its
medium length
• Backing pads ⑩
- never run the tool without backing pad G
! replace damaged backing pads immediately
(loosen/fasten pad screw H with hex key C)
! unplug tool before removing/mounting backing
pads
• Mounting sanding discs ⑪
- simply press sanding disc J onto backing pad with
perforation in sanding disc corresponding with
perforation in backing pad
- if necessary, clean backing pad first
! the dust suction requires the use of perforated
sanding discs
• Dust suction ⑫
- loosen locking sleeve E by turning it in the direction of
the unlocking symbol on the tool handle
- insert flexible hose K into the end of the tool handle as
illustrated
- tighten locking sleeve E by turning it in the direction of
the locking symbol on the tool handle
- connect the flexible hose with the Ø 57 mm adapter
directly to an industrial vacuum cleaner (remove
vacuum cleaner hose first)
- one may also connect flexible hose K with one of the
3 adapters to an industrial vacuum cleaner without
removing the vacuum cleaner hose
- for mounting vacuum cleaner adapter L or M use
screwdriver N as illustrated
• Tool standard/airflow control ⑬
- tool standard P prevents the hose from damage when
putting the tool aside during work breaks
- control the airflow by sliding regulator Q over the
opening in tool connector R
- the vacuuming power is at its lowest level when the
opening is fully visible
• On/off locking switch S ⑭
- switch on tool ⑭a
! before the accessory reaches the workpiece, the
tool should run at full speed
- lock switch ⑭b
- unlock switch/switch off tool ⑭c
! before switching off the tool, you should lift it
from the workpiece
! the accessory continues to rotate for a short time
after the tool has been switched off
• Electronic soft-start
Ensures reaching the maximum speed smoothly without
a sudden impact when tool is switched on
• Electronic constant speed
Keeps the speed at a constant level as the load
increases
• Speed control ⑮
For optimal sanding results on different materials
- with wheel T you can adjust the sanding speed
steplessly from minimum to maximum
- always adjust speed to grit size used
- before starting a job, find the optimal speed and grit by
testing out on spare material
• Holding and guiding the tool ⑯
! always hold the tool firmly with both hands
! while working, always hold the tool at the grey-
coloured grip area(s)
- guide the tool parallel to the working surface and move
it in circles or in a cross pattern
! do not apply too much pressure on the tool; let
the sanding surface do the work for you
- do not tilt the tool in order to avoid unwanted sanding
marks
- keep ventilation slots V ② uncovered
• Sanding
- the amount of material removed is determined by the
speed of the sanding disc and the grit size used
- the speed of the sanding disc decreases relative to the
pressure applied to the tool
APPLICATION ADVICE
