1 General
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!

4M4082E ZA 2022-07 CSP1 S
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.

5M4082E ZA 2022-07 CSP1 S
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)

6M4082E ZA 2022-07 CSP1 S
1.5 Personnel qualification
Only authorised and qualified personnel may be entrusted with work with and on
the conveyors and cleaners. Persons are considered qualified if they have the
qualification of a skilled worker and meet all the following requirements:
•completed professional training or at least 5 years of professional
experience in the field,
•technical experience,
•knowledge of the relevant occupational health and safety regulations.
The persons must
•be able to assess the tasks and risks assigned to them,
•be able to recognise potential dangers in advance,
•be physically and cognitively able to operate the conveyors and cleaners
safely,
•have been trained and instructed appropriately,
•have read and understood these operating instructions.
Work on earth connections, cabling, switching, control, regulation, automation,
and all electrical components may be carried out only by trained electricians.

2 Safety
2.1 General safety instructions
DANGER
Entanglement in conveyor belt
Clothing or body parts can become entangled in the conveyor and cause serious or
fatal injuries.
Tensions may be released in the conveyor belt and cause movement of the bulk
material without prior detection.
−Do not carry out any work on the conveyor belt while it is in operation or
reach into the moving conveyor belt!
−Secure the conveyor against unintentional restart! Use lockout / tagout /
blockout / testout procedures!
−Install suitable guards to prevent access to the infeed section!
WARNING
Danger of injury due to unapproved component parts
Unapproved parts can directly or indirectly cause personal injury or damage to
property.
−Only use accessories and spare parts that are distributed by the
manufacturer or are explicitly approved (in writing)!
WARNING
Working in confined spaces
Areas in which cleaners are installed are often difficult to access and include
confined spaces. It is often necessary to work in difficult positions.
−Determine whether occupational safety measures are necessary that go
beyond the usual measures!
WARNING
Risk of falling down
Cleaners are often mounted and operated in heights. There may be a risk of falling
down.
−Therefore, use a fall protection device when installing in higher working
areas!

9M4082E ZA 2022-07 CSP1 S
2.2 Personal protective equipment
Persons carrying out work on cleaners must wear suitable personal protective
equipment.
Minimum requirements:
2.3 Safety markings on the system
The safety markings on the cleaners must be always kept in good condition and
clearly visible.
If parts of the system are replaced, ensure that the spare parts are or will be
provided with appropriate warning signs.
Symbol
Meaning
Wear head and eye protection.
Wear at least ankle-high foot protection.
Use gloves.
Use fall protection.

2.4 Special safety instructions for usage in ATEX areas
DANGER
Usage in ATEX zones 22 and 21
Combustible dust can cause explosions and thus cause serious or fatal injuries.
−Ensure that all explosion-related parameters and operating modes are
observed.
−Observe all instructions for usage in hazardous areas.
−Ensure that the bulk material meets the specified requirements before the
conveyor is switched on.
−Ensure that the cleaners are suitable for all explosion-related parameters and
operating modes of the application.
−Ensure that the conveyor belts do not have any metallic connectors. All belt
connections must be vulcanised.
−Ensure that the bulk material is free of foreign substances that could create
an ignition source for the dust/air mixture.
−Ensure that any necessary metal-separating devices are operating
effectively.
−Install cleaners in such a way that no metal part can contact moving
components even when the blade is completely worn.
−Use only tools and aids that are approved for use in the respective ATEX
zone.
−Ensure that the cleaners are tensioned against the conveyor belt with the
maximum forces / tension values specified.
−Ensure that the earth connections of the cleaners are installed correctly.
−Use only cleaners as special product variants that are suitable for use in
potentially explosive areas.
−Measure the gas and dust content of the environment before using open
flames.
−Prevent electrostatic charges, for example by cleaning plastic enclosures with
a dry cloth.
−Work on earth connections, cabling, switching, control, regulation, automation
and all electrical components may be carried out only by trained electricians.
