1 INTRODUCTION:
1.1 Purpose of the operating manual:
This manual is aimed at the operator and especially the personnel responsible for
using the machine correctly and thereby achieving good safety at work. It is, then,
recommended that the manual be read through carefully, paying particular attention to
the sections on warnings, precautions and methods of use, and that it is kept close to
hand for future reference, preferably next to the machine itself.
1.2 Presentation:
KM 775 edge banding machines are automatic machines equipped with a bottom
vertical gluing station, pressure rollers, front and back end trimming station, trimming
station, radius scraper, polisher and both top and bottom corner rounding station, as
well as a number of other features depending on version.
1.3 Reference standards:
KM 775 edge banding machines are designed and built in accordance with the
following standards:
Directive community: 2006/95/CE, 2004/108/CE, 2006/42/CE
Harmonized norms: EN 14121:2007, EN 60204-1:1999, EN 13849-1:2008, EN

cases where the machine has not been correctly connected to the earthed (grounded)
equipotential installation, such that the protective devices behind the machine itself are
not operative. For this reason, explicit reference is made to the entire contents of the
chapter relating to the characteristics of the electrical installation.
Original spare parts only must be used for special maintenance and repair work.
It is always advisable to contact our technical assistance service concerning
repairs. The responsibility for perfect machine operation rests solely with the user, if the
equipment has not been repaired or maintained by personnel authorized by ROBLAND.

2 MACHINE INSTALLATION:
2.1 General safety rules at the KM 775 edge banding machine
installation:
The person in charge of the machine must be instructed in how to use the machine
correctly and informed of the relevant safety devices and tools and accessories.
The devices fitted to the edgebander must be correctly set up and adjusted.
The appropriate routine and special machine maintenance tasks must never be
neglected.
Before starting each job and before switching the machine on, check that the
control and working stations are free from chippings of previously removed
material.
The machine operator must always wear suitable safety clothing bearing in mind
the type of activity being carried out, protective gloves, safety footwear and
spectacles or goggles for example. Remember never to wear clothing or objects
that may get caught in the machine such as loose clothing, ties, watches, rings and
so on.
Before beginning any operation, check that there are no persons or other obstacles
in the vicinity of the machine that may present a risk.
Make sure the cable connecting the machine to the electrical supply is fully
unwound and not coiled up.
Do not situate inflammable substances near the machine to prevent the risk of an
accidental spark causing fire or explosion.
The machine operator must always consider the possible consequences before
moving his hands towards the most dangerous zones.
Never remove the yellow protections located on the gluing set, as they prevent the
risk of burns to the operator.
The operator must always be particularly careful when working the pedal that sets
the machine into operation.
Always keep the machine switched off when not in use.
Do not enter, touch or handle zones where movements take place before switching
the machine off.

2.2 Limits of use:
This machine has been designed to work with the following materials:
Solid wood
Laminated or unlaminated chipboard
M.D.F.
Various compound materials, provided they are wood-based
The machines have been designed and built to work in closed industrial
environments. Sitting the machine in an unsuitable location must be considered as
improper use. The machines are not intended for edge banding materials other than
those described, and any such use must also be considered as improper.
