INTRODUCTION
1.1 FEATURES OF THE MACHINE
Figure 1 depicts the TRIO with the main components designated.
Take your time to become familiar with the machine.
1.2 DESCRIPTION OF THE MACHINE
The TRIO works with three sanding discs that are suspended in a
freely rotating support. The working area is fully covered by the
machine housing.
The motor and switch box are positioned vertically on the machine
housing. One of the cables leads to the power supply, the other to
the on/off switch which can be positioned either on the switch box
or below the guide handle.
The chassis consisting of the frame with guide tube, wheels and
adjustable handle is mounted to the sanding unit with two cross
grip fasteners and can be removed for transport purposes.
A dust separator is fixed to the chassis and connected to the
dust suction system of the sanding unit by a flexible suction hose.
Dust is separated by a coarse filter system and collected in the
disposable dust bag.
Inside the dust bag box the dust bag is fastened to the dust
separator with a MultiClip. The transparent dust bag box can be
opened using two fasteners.
The air coming from the dust separator passes through a fine
particle filter behind the perforated cover before being blown
out into the environment. A sensor checks the air-pressure in the
dust separator and a red warning lamp lights up when the suction
capacity is too low.
To return to the correct suction capacity, the cleaning slide must
be used to clean the fine particle filter.

HAZARD WARNINGS AND SAFETY INSTRUCTIONS
RISK OF DEATH from unsecured load:
• When transported in a car or the like, the machines and all
parts must be secured against sliding!
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,
changing 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

• The dust bag must always be removed from the machine
directly after sanding! Seal and dispose the dust bags in
a non-combustible container! Cover this container with a
non-combustible cover ( Section 5.5, Changing the dust
bag)!
• Always transport and store the machine without dust bag!
