Introduction
2.2 Intended usage
The secondary cleaner can be used exclusively for the cleaning of a
conveyor belt in the bottom belt conveyor of a conveyor system. For
this purpose, the cleaner must be installed directly behind a head
pulley or counter-pressure roller.
It can be used on conveyor belts with a maximum belt width of
2400 mm and a maximum conveyor speed of 5 m/s.
Every other usage of this product is deemed as misuse. Please
contact Martin Engineering customer service if you would like to use
this product for a different purpose. We will be happy to assist you
with the product configuration.
2.2.1 Conveyor systems with open transfer systems
These installation instructions describe the installation on conveyor
systems with encapsulated transfer systems. Various MARTIN®
installation brackets can be used on open transfer systems.
Martin Engineering or one of its representatives can assist with the
position or with special solutions in cases where the installation
conditions are complicated such as insurmountable static
components or a head pulley as the tensioning station.
2.2.2 Usage in explosion-protected areas
This product can also be used in potentially explosive areas under
certain conditions. Contact Martin Engineering for more information
on usage in potentially explosive areas.
The cleaner must not be used in a higher equipment protection
category or under other operating conditions than those specified by
Martin Engineering unless such usage has been approved by
Martin Engineering.

Description of the product
3 Description of the product
3.1 Design and function
With its individually spring-loaded tungsten-carbide blades, the
secondary cleaner provides effective cleaning without damaging
either the conveyor belt, possible splices or the cleaner itself. The
rubber buffers of the tungsten-carbide blades cushion impact on the
one hand and maintain the required cleaning pressure on the other
hand.
3.2 Tensioners
The secondary cleaner and its specially developed Martin
Engineering Inline Reversing tensioners offer the best possible
results and correspond to the general state of the art.
The SQC2™ secondary cleaner can be operated exclusively with
the following tensioner:
•MARTIN
® SQC2™ tensioner,
part no. SQC2-35701-XX
3.3 Type designation
Den MARTIN® SQC2™ secondary cleaner is available in three
different designs
• with aluminium cartridges for general usage.
• without aluminium cartridges for additional usage in
explosive areas where no aluminium is permitted.
• as a miniature design for tight installation spaces.
NOTE
An unfavourably or improperly installed product can disrupt the
conveyor process or contaminate the bulk material to be
transported.
The owner-operator is responsible for taking the required
countermeasures.
In the case of applications with contaminants Martin Engineering
or one of its representatives can assist with the positioning or with
special solutions.

5.1 Safety information
NOTE
Read this section completely before starting any kind of work!
WARNING RISK OF INJURY!
Body parts and/or clothing may get caught and pulled in by
rotating parts or by the moving conveyor belt.
Before any installation or maintenance work is carried out ensure
that all power sources to the conveyor belt system and its
accessories are switched off and secured against unauthorised
reactivation. Use warning signs!
WARNING DANGER OF EXPLOSION!
Increased risk when using a cutting torch or welding device in
closed spaces!
Check the gas and dust content of the air before usage.

Installation
5.2 Installation process
5.2.1 Determination of the installation position
The position of the axle and the tensioning device of the secondary
cleaner must be determined on both sides of the chute wall. In this
process, the positions are therefore determined for where the shaft
of the secondary cleaner is routed through the chute wall and/or
where the tensioner is installed on the chute wall.
The secondary cleaner is delivered jointly with a tensioner. This is
delivered as a work´s dismantled unit and will be installed together
with the secondary cleaner during the general installation.
The installation process for the secondary cleaner and the tensioner
is described in the supplied installation instructions.
An overview of the installation steps follows:
Various on-site conditions requiring different work steps are
possible for the installation. These are presented as follows:
Installation on an encapsulated transfer system
• Follow the instructions in Section 5.2.2. ff
Installation on an encapsulated transfer system with pre-existing
installation openings and air line brackets for belt cleaners.
• Follow the instructions in Section 5.2.3. ff
Installation on an open transfer system
• Use the equipment provided at the site to comply with the
dimensions for correct installation.

2. Mark the vertical and horizontal centre line of the driving drum
on the operator side of the chute wall to determine the centre
point (A, Fig. 4) of the driving drum. The vertical line must run
at a right angle with respect to the conveyor belt line.
3. Mark a position (E, Fig. 4) at a distance from 50 mm to no more
than 100 mm in the conveying direction (D, Fig. 1) from the
point at which the belt leaves the head pulley (C, Fig.4).
4. Draw a vertical line at this position (E, Fig. 4) going downwards
at a right angle to the conveyor belt.
5. Use the dimensions from Tables 2 and 3 to mark the installation
holes for the tensioner (G, Fig. 4).
6. Create the cut-out and installation holes as shown in Fig. 6/Fig.
