Description of the product
3 Description of the product
3.1 Design and function
Der MARTIN®PIT VIPER™ Pre-Cleaner was specially developed to
simplify blade replacement and to reduce costs. It makes it possible
to quickly and easily replace the blade without any tools by removing
a single pin.
Although pre-cleaners and secondary cleaners can each be used in-
dividually, the installation of a system consisting of pre-cleaners and
secondary cleaners is recommended for an optimal cleaning result.
3.2 Tensioners
The 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 cleaner can be operated solely with the tensioners listed below:
•MARTIN
®TWIST™ Tensioner:
Part number 31443-I+E.
•MARTIN
®Cable Tensioner:
Part number 37944.
NOTE
An unfavourably or improperly installed product can disrupt the
conveyor process or contaminate the bulk material to be trans-
ported.
The owner-operator is responsible for taking the required counter-
measures.
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
The item numbers in the pictures correspond to the numbering in
the parts list in Section 9.
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 inadvertent
reactivation. Use warning signs!
WARNING! RISK OF EXPLOSION!
Increased risk when using a cutting torch or welding device in
closed rooms!
Check the gas and dust content of the air before usage.
NOTE
The chute wall on which the In-line-Reversing tensioner is to be
installed is designated as the “operator side”. The other chute wall
is referred to as the “far side”.
When dual In-line-Reversing tensioners are installed, the easiest
side to access is the “operator side”.
WARNING! RISK OF INJURY!
The pre-cleaner is heavy and can cause serious injuries if it is
dropped during lifting or moving.
Always use a suitable lifting device or engage the help of several
persons when lifting the pre-cleaner. Do not stand under hanging
loads.

Installation
5.2.1 Determination of the installation position.
1. Determine the centre point of the head pulley (1, Fig. 1) on the
operator side.
2. Drop a perpendicular (2, Fig.1) to the lower conveyor belt level
(3, Fig.1).
3. Determine radius R.
4. Draw the arc of a circle (4, Fig. 1) with radius R.
NOTE
The pre-cleaner is installed exclusively in the lower front quarter of
a head pulley. Always comply with the specified installation
dimensions.
Fig. 1
NOTE
Radius R results from the sum of: pulley radius, coating thickness,
belt thickness and a constant value between (70-76 mm). This
value is freely selectable. The selected value must also be used
for the far side.

5. Mark a point on the perpendicular which is at least 178 mm from
the centre (1, Fig. 2).
6. Draw a line vertical to the perpendicular at this point (2, Fig. 2).
7. The point of intersection (3, Fig. 2) with the arc of the circle is
the installation position of the pre-cleaner.
8. Repeat steps 1 to 7 on the far side of the chute wall.
