INTRODUCTION
1.1 FEATURES OF THE MACHINE
In figure 1 we have indicated 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 tension 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 cable is used to connect the
machine to the power supply system. The motor switch with ON/OFF
positions is located on the switch box cover of the motor housing.
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 rotatable pipe socket is mounted on the rear of the fan housing
which feeds the sanding dust into the dust bag. The dust bag is
connected to the pipe socket via a flange with two quick-release
fasteners. The power cable is attached to the bag’s fixing bracket
with Velcro tape so that it is kept out of the working area of the
machine.
There are three different attachments for the FLIP®(part numbers
are in Section 11, Spare parts FLIP®):
• short attachment for sanding edges and stairs
• long attachment for sanding edges and below radiators or
similar objects
• attachment for sanding corners (corner attachment)
1.3 PROPER USE AS INTENDED
The FLIP®edge-sanding machine is suitable for the dry sanding
of wooden floors, cork floor and wooden stairs in the professional
and rental business sectors.
Any other form of use is not permitted without the approval of the
manufacturer!

RISK OF EXPLOSION due to sparks while sanding or a high dust
concentration in the air:
• Do not use the machine near
- sources of fires,
- flammable liquids or gases,
- potentially explosive areas!
• Do not smoke in a dusty environment, e.g. while sanding,
emptying the dust bag or cleaning the machine!
RISK OF FIRE from sparks while sanding or from spontaneous
combustion:
• Prior to sanding a nailed or screwed floor all nails or screws
must be countersunk deeply enough so that they cannot be
sanded:
- Countersink the nails for example with a hammer and a
punch!
- Tighten the screws!
• There is a high risk of fire when sanding woods with a large
amount of resin, oiled or waxed floors or metal! Therefore,
the machine must always be cleaned carefully directly
after sanding! Be certain to note the warning notices of the
manufacturers of paint, oil and wax!
• Cloths, pads, et cetera which have been immersed in oil or
wax can spontaneously combust! Be certain to note the
warning notices of the manufacturers of paint, oil and wax!
• The dust bag must always be removed from the
machine directly after sanding and emptied into a
waste bag with the emptying fixture! Dispose of these
waste bags in a non-combustible container! Cover this
container with a non-combustible cover and be certain
to store it outdoors in non-combustible environment
( Section 5.3, Emptying the dust bag)!
• Always transport and store used dust bags in closed and
non-combustible containers!
• Always transport and store the machine without dust bag!
