• The instructions regarding PPE apply for all
persons within the work area in addition to the
machine operator.
• The sanding of extremely hazardous materials
(e.g. paints with lead content and asbestos) is
highly toxic and should therefore be avoided or
only carried out by specialists wearing appropriate
PPE.
• Ensure that your workplace is clean and well-lit at
all times to prevent accidents.
• When working with electric power tools
outdoors, only use extension cables suitable for
outdoor use.
4.4 Recoil
Recoil is a sudden reaction to a jammed, hooked
or blocked accessory, e.g. the abrasive or driving
disc. The rotation of the accessory is blocked and
comes to a sudden standstill. This causes the
electric power tool to respond with increased
speed against the rotational direction of the
accessory at the location of the blockage. For
example, when a sanding disc hooks or jams
on the workpiece, the edge of the sanding disc,
which dips into the workpiece, may get caught
and break out the sanding disc, tear off or react
in a recoil. Depending on the rotational direction
of the sanding disc at the jamming point, it can
be ejected toward or away from the machine
operator. The sanding discs may also break at the
jamming point.
A recoil is the result of improper or incorrect use
of the machine, incorrect work practices and/or
unfavourable operating conditions. The following
safety measures minimise the risk of recoil:
• Hold the machine securely with both hands and
place your arms and body in such a way as to have
maximised control over recoil forces and reaction
momentum.
• Keep your hands away from rotating accessory
parts at all times, as they may recoil back across
your hand.
• Stay clear of the area of movement of the electric
power tool in case of a recoil and prevent other
from entering that area, as the device will be
8 GB
accelerated against the rotational direction of
the abrasive at the jamming point when a recoil
occurs.
• Take extra care when working in corners and
along sharp edges, etc. Prevent the electric power
tool from rebounding or jamming in these areas.
The result would be loss of control and recoil.

5.3 Commissioning (page *5*–*11*)
Caution! The mains plug must be disconnected
from the mains socket and must not be
plugged into the mains socket for all works
described in the following!
a. Remove the respective machine from the
packaging.
In TSW devices (page *5*–*7*): Remove the
body of the machine (main unit) and the
round or triangular replaceable head from the
package. Open the locking mechanism of the
replaceable head by pressing the two levers
on the outside of the unit (1a.). Push the re-
placeable head and main unit of the machine
together via the joining elements for a form-
locked fit (2a.–4a.). Make sure that the drive
pin is aligned correctly. Then release the clasp
levers of the head attachment (2a.).
To replace the replaceable head, loosen the
locking mechanism on the lever on the main
body of the machine and separate the replace-
able head from the main body of the machine
by pulling it upwards (1b. and 2b.).
b. Attach a suitable abrasive centrically on the
velcro backing pad of the tool (1c. and 2c. – see
page *8*)
Caution! The extraction openings of the
abrasive must be placed directly over the
openings in the velcro backing pad to minimise
dust production during operation (2b).
c. Attach an industrial vacuum cleaner to the tool
using a click or plug-in system. Follow the illustra-
tions on page *9* (1d. and 2d.) to connect the
industrial vacuum cleaner via the MENZER system.
Three velcro straps are attached to the
power cable. You can place these evenly
spaced around the suction hose. The closed velcro
connection links the cable and the suction hose
together and provides more stability when
working (1e. and 2e. - see page *9*).
Please follow the instructions on the following two
pages *10* and *11* (1f. and 2f. for the attach-
ment of the adapter; 1h.–1i. for the attachment/
removal of an industrial vacuum cleaner to/from
the adapter) for machines requiring an interme-
diary fitting of a MENZER universal adapter for
vacuum hose systems with hose diameters Ø
27-50 mm. Ensure that a dust bag suitable for
fine dust collection is in place inside the industrial
vacuum cleaner.
AV machines do not require a connected indus-
trial vacuum cleaner, as they have an integrated
extraction system. Only connect our M-certified
dust bag system to these machines (refer to point
10. for Functional accessories and peripherals).
d. Ensure that the on/off button is not pressed be-
fore connecting the power cable to mains supply.
5.4 Settings and handling
(Page *10*–*14*)
a. Switch on the industrial vacuum cleaner first,
and then the drywall sander. Hold the machine
securely and press the on/off button. At the same
time unlock the pushbutton safety guard (A and
B – refer to page *4* / *12*). Expect a rotational
effect when you switch the machine on.
b. Grip the drywall sander firmly with both hands
positioned within the insulated grip areas (D1 and
D2 – refer to page *12*).
c. The rotational speed can be steplessly adjusted
as needed via the speed dial (C – see page *4* /
*12*). Speed adjustments can be made during tool
operation. Higher speeds allow more abrasion,
while lower speeds ensure more control over the
sanding process.
Sanding performance, quantity and quality
depend largely on the correct choice of
abrasive.
d. Begin the sanding process by gently lowering
the device onto the substrate.
Press down with moderation to ensure that
the cup wheel lies flat and flush against the
substrate. Pressing down with too much force can
result in spiral-shaped scratch patterns on the
substrate and may damage the tool long-term. We
recommend using a circular, overlapping forward
motion of the sanding head across the work area.
The sander should remain in constant motion until
the desired refinement is achieved, as prolonged
sanding in place will result in abrasion marks.
Too much pressure will result in an overloading of
the machine and overheating of the sanding disc
and backing pad, leading to premature wear.
The sanding quality and performance depends
largely on the correct choice of abrasive.
In TSW devices: The triangular sanding head
does not have a rotating, but an oscillating
sanding motion. Less pressure should be applied
in the corners to protect the tips of the head
against overload and deformation.
