You have purchased a high-quality product
from LÄGLER®. We wish you a great deal
of success with your ELAN. All LÄGLER®
products are subjected to a thorough
inspection before leaving the factory.
Read these operating instructions
completely before working with the
ELAN for the first time! These operating
instructions include important information
on occupational safety and will provide
you with answers to many questions
so that you can work with the machine
safely and without any problems. If you
cannot find a specific subject in these
operating instructions, please read
the LÄGLER®application technique
manual “Sanding of wooden floors”
(http://www.laegler.com) or contact our
service department, your retailer or your
importer.
1.1 FEATURES OF THE MACHINE
In figure 1, we have indicated the most important components of
the ELAN. Take your time to become familiar with the machine.
1.2 DESCRIPTION OF THE MACHINE
The edge-, stair- and corner-sanding machine ELAN works with
a sanding disc 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 side in the handle
piece. 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. The suction muff, to which the dust bag clamp and the dust
bag are attached, is located underneath the handles.
For the ELAN are three different attachments available (part
numbers in Section 11, Spare parts ELAN):
• short attachment for sanding edges and stairs
• long attachment for sanding edges and under radiators,
cabinets, shelves and the like
• corner attachment for sanding in corners
1.3 INTENDED USE OF THE MACHINE
The edge-, stair- and corner-sanding machine ELAN 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 is not permitted without the approval of the
manufacturer!
Introduction
WARNING!
RISK OF DEATH from electrical shock:

HAZARD WARNINGS AND SAFETY INSTRUCTIONS
RISK OF DEATH and RISK OF PROPERTY DAMAGE 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,
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 non-combustible
container outdoors! Cover this container with a non-
combustible cover and be certain to store it and the dust bag
outdoors in non-combustible environment ( Section 5.5,
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!
