1.1 FEATURES OF THE MACHINE
In figure 1 (page 2), we have included the designations of the most
important components of the FLIP. Take your time to become
familiar with the machine.
1.2 DESCRIPTION OF THE MACHINE
The FLIP edge-sanding machine works with a sanding plate on
which Velcro sanding discs can be fastened. Traditional sanding
discs fastened with a tensioning screw can, of course, also be
used. The work zone is protected by the attachment. The fan
housing, on which the electric motor is mounted in vertical position,
is located on the attachment. A motor power supply cable is used
to connect the machine to the power supply system. The motor
switch with ON / OFF is located on the right-hand side of the motor
in the switch box. The machine is moved by means of two guide
rollers at the rear side of the machine. The handles are located on
top of the motor.
A rotable elbow piece mounted in a tube socket on the rear of the
fan housing, feeds the sanding dust into the dust bag. The dust
bag is connected to the elbow piece via a flange with two quickrelease fasteners. The power cord is fixed to the bag’s fixing bracket by a Velcro tape so that it is kept out of the working area of
the machine.
The FLIP can only be used for dry processing operations. Never
use the FLIP for wet processing operations (life-threatening risk)!
1.3 PROPER USE AS INTENDED
The edge-sanding machine FLIP is suitable for the dry sanding of
wooden floors, cork floors and wooden stairs in the professional
and rental business sectors.
Any other form of use without the approval of the manufacturer is
not permitted.

WORKING WITH THE FLIP
4
4.1 GENERAL APPLICATION TIPS
The FLIP is a very versatile machine. The required attachment can
be replaced in a matter of seconds. The FLIP is used for fine
sanding of transitions, borders, edges, corners and stairs.
Deep sanding marks due to the selection of a too coarse
sandpaper grain size can be prevented by starting the first sanding
operation with a fine sandpaper grain size to the extent possible.
Prevent sanding marks made by previously used sandpaper grain
sizes by adhering to the order of the sandpaper grain sizes and
never skip more than a sandpaper grain size. Following each
sanding operation, vacuum the floor thoroughly.
After changing over to a new sanding disc, start working in poorly
lit areas in the room in order to remove the initial aggressiveness
of the sanding disc.
Bear in mind that the FLIP operates at very high cutting speeds.
For this reason, danger of burn marks exists for finer sandpaper
grain sizes!
Do not apply excessive pressure to the attachment. This will
significantly worsen the sanding finish by causing deep scratches,
and could cause the motor to become overheated and switch off.
Please refer to the LÄGLER sanding instructions for additional
important and interesting application tips.
4.2 REPLACING THE SANDING DISC
Depending on the processing operation, you will use various
sandpaper grain sizes. To replace the sanding disc, proceed in
the following manner:
4.2.1 VELCRO SANDING DISCS
1 Switch off the machine.
2 Always pull the power supply plug out of the socket!
3 Turn the machine upside down or lay it on its side, avoiding
damage to the floor and machine.

4.3 EMPTYING THE DUST BAG
The dust bag must be emptied when it is one-third full at the very
latest in order to prevent a deterioration of the suction
performance due to the missing filtering surface area. The horizontal line on the outside of the dust bag marks the maximum filled
level. When emptying the dust bag, it is advisable to wear a
respiratory protective mask (P3).
To empty the dust bag proceed as follows:
1 Switch off the machine.
2 Always pull the power supply plug out of the socket!
3 Remove the extension cable coupler from the Velcro loop
on the dust bag (Fig. 13).
4 Before emptying, shake the dust residue into the dust bag
(Fig. 14).
5 Open the two quick-release fasteners on the locating flange
(fig. 15).
6 Slowly pull the dust bag off the locating flange (Fig. 15).
7 Hold the handle of the emptying fixture and insert a waste
bag from the ribbed side through the opening in the centre
of the fixture (Fig. 16).
8 Pull the waste bag over the emptying fixture from behind
(Fig. 17).
9 Take hold of the emptying fixture with the waste bag in one
hand and the dust bag in the other. Hold the dust bag at a
slight angle to prevent dust escaping.
10 Insert the dust bag into the emptying fixture. Make sure
the rods are in the correct position. The pins have to fit into
the openings provided (Fig. 18).

contacts are used to prevent the collector from being damaged
by completely worn-out carbon brushes. These safety contacts
will switch off the machine automatically when the wear limit is
reached. The carbon brushes should, however, be replaced at
least once a year in order to prevent damage to the machine!
1 Switch off the machine and always pull the power supply
plug out of the socket!
2 Undo the four fixing screws of the handle and remove it
from the motor housing, ensuring that no small parts fall
into the motor (Fig. 40 + 41).
3 Pull off the connector of one of the carbon brushes from
the carbon holder (Fig. 42).
4 Use the universal spanner to turn the brass pressure clamp
so that it faces the back and remove the worn carbon brush
(Fig. 42).
5 Insert the new carbon brush and turn back the brass
pressure clamp (Fig. 43).
6 Fix the carbon brush connector on the contact provided.
Install the carbon brush cable as for the other old carbon
brush that is still installed, to avoid subsequent pinching of
the cable (Fig. 43).
7 Now replace the second carbon brush in the same way.
8 Now refit the handle to the motor housing.
Fig. 42 Pull off the connector, turn the brass pressure clamp
to the back and remove the carbon brush.
Fig. 43 Insert the new carbon brush, turn back the brass
pressure clamp and attach the connector.
Professional tip:
You should have a qualified electrician clean
the collector by removing the carbon fines every
other time the carbon brushes are changed to
extend the service life of the motor!

6.6 CHECKING THE DUST SUCTION SYSTEM
In order to guarantee optimal dust suction for your safety and for
the safety of other persons, the following items must be taken into
account:
• Always use original LÄGLER dust bags FLIP (Art. no. in
Section 11, Spare parts
).
• Do not use any damaged dust bags.
• Ensure that the guide rollers are correctly positioned.
• Check the suction system for any clogged-up material or
deposits.
• Make sure that the dust bag and locating flange are
connected properly.
6.7 ADJUSTING THE GUIDE ROLLERS
The position of the guide rollers will have an effect the sanding
results and the aggressiveness of the machine. For rough sanding
tasks, a large setting angle is selected. For fine sanding tasks, a
flat setting angle.
The two alignment marks on the universal spanner can be used to
set a position for the guide rollers, which is suitable for both rough
and fine sanding work, for the short and long attachment.
This is achieved by holding the corresponding alignment mark of
the universal spanner, that depends on the attachment used,
between the guide roller and the fan housing and this spacing is
then set (see below for procedure).
This setting allows a horizontal and even sanding setting, which
does not overload the machine and leads to an even and attractive
sanded finish.
In special cases the setting must be adjusted to the circumstances,
however it is easy to find the standard setting again using the universal spanner.
The high cutting speed of the machine allows you to work fast.
The machine must be moved quickly without applying extra
pressure. If a higher amount of removed material is demanded,
the setting angle must be adjusted to a steeper setting!

To adjust the guide rollers, proceed in the following manner:
1 Switch off the machine and always pull the power supply
plug out of the socket!
2 Loosen the locknut of the guide roller to be adjusted.
3 Hold the appropriate universal spanner alignment mark for
attachment used between the guide roller and fan housing,
namely so that the lettering on the spanner faces towards
the fan housing (Fig. 44 + 45).

- long attachment: long
- corner attachment: short
4 Now turn the guide roller in the direction required and re-
tighten the locknut.
5 Perform a trial sanding operation and check the sanding
results (Fig. 46 – 50). Should you require a steeper or flatter
setting, loosen the locknut again and turn the guide roller
one or two turns in the relevant direction and then tighten
the locknut again.

6.11 CLEANING THE MACHINE FOLLOWING
RESTORATION TASKS
Following restoration tasks, residual material consisting of
adhesive, wax or sealing lacquer may have accumulated on the
belt pulleys or in the attachment.
This can impair the running characteristics of the machine and
reduce the suction performance. This kind of soiling is indicated
in most cases by unsteady running, difficult starting, reduced
working speed and increased development of noise. The suction
performance also decreases. In this case, the V-belt must be
dismantled as described in
Section 6.2
and the attachment as well
as the flanks of the belt pulley be cleaned. Check the fan for any
deposits. Wear a respiratory protective mask (P3).
