1.1 About these operating instructions
These operating instructions apply solely for cleaners and are intended for
those persons who install cleaners, commission them, and monitor their usage.
The operating instructions must be kept for the lifetime of the cleaners and must
be made available in an orderly condition to all persons entrusted with work with
and on the cleaners.
All illustrations are schematic representations and make no claim to
completeness.
NOTE
Before starting work on the cleaner or the conveyor, these operating
instructions must be read and understood completely

1.2 General information on cleaners
Cleaners are used in the discharge area of the belt conveyor to remove
adhering bulk material from conveyor belts. The cleaning result is increased by
using multiple cleaners.
Pre-cleaners are installed at the head pulley, below the discharge parabola of
the bulk material.
Secondary cleaners are installed behind pre-cleaners when viewed in the
direction of belt travel and are used for fine cleaning of the conveyor belts. The
typical installation position is behind the discharge pulley, but still inside the
chute enclosure.
These operating instructions describe actions and measures for the use of
cleaners on closed discharge enclosures of the conveyor. If the discharge area
of the conveyor is not enclosed, the operator must take precautions to ensure
that the cleaners can be relocated, installed, maintained and repaired in the
same way.
Furthermore, the operator must ensure that all necessary protective measures
for safe operation of the system with cleaners have been taken.
Cleaners must be easy to check, clean and maintain. Appropriate means of
access must be provided for this purpose.
1.3 Intended usage
Cleaners are used for mechanical removal of bulk material sticking on conveyor
belts with smooth surfaces. They may only be used:
in the industrial area above ground
on the carrying side of the conveyor belts
according to the technical data in the documentation
in the installation position as described in the documentation
The usage of the cleaners is only considered to be as intended if the following
conditions are also fulfilled:
Before starting initial work, the personnel must have been instructed on
the work on the system and on all relevant issues of occupational health
and safety
Any personal protective equipment required must be worn
The provisions of the operating instructions must be observed in full.
Operation of the cleaners under deviating conditions and unauthorised
modification of the cleaners is considered as improper usage.

1.4 Use in hazardous areas according to the ATEX directive
The standard version of the cleaner is NOT suitable for use in hazardous areas.
Martin Engineering offers special product variants that are suitable for use in
ATEX zones 22 and 21 under certain circumstances. These product variants
contain mandatory additional components or have special product
characteristics.
Special instructions for the use of cleaners in ATEX zones must be observed.
Requirements for the use of these special product variants:
Minimum ignition energy of the bulk material: >10 mJ
Belt connections are vulcanised
There are no substances in the bulk material which could generate
impact sparks on the cleaners.
Coatings (corrosion protection) have standard layer thicknesses
(max.80µm)
Earthing cables are properly installed (Bleeder resistance < 106Ω)
