Introduction
General To introduce product back into the product flow, a Pre-Cleaner is installed on
the face of the head pulley. On a dual cleaner system, the Secondary Cleaner
is installed immediately following the Pre-Cleaner to remove stubborn
material left on the conveyor belt. If a Pre-Cleaner cannot be used because of
space limitations, the Secondary Cleaner is installed alone. If the material-
handling process or product could be affected by contamination from the use
of these belt cleaners, the user is responsible for taking the necessary steps to
prevent contamination. Consult Martin Engineering or a representative for
alternate belt cleaners or belt cleaner locations to use where contamination
may be an issue.
Installations
without chutework
These procedures were written for equipment that is being installed on
enclosed pulley chutework. If the pulley is not enclosed, the equipment should
be installed using the best available field resources and methods to ensure that
the critical dimensions are followed for proper installation.
Belt cleaner
inspection access
If the belt cleaner is installed on enclosed pulley chutework, a MARTIN®
Inspection Door should be installed. MARTIN®Inspection Doors are
available from Martin Engineering or a representative. See “Part Numbers”
for a list of MARTIN®Inspection Doors and part numbers.

rules must be strictly followed when working on the belt cleaner.
DANGER
!
Do not touch or go near the conveyor belt or conveyor
accessories when the belt is running. Your body or clothing
can get caught and you can be pulled into the conveyor,
resulting in severe injury or death.
DANGER
!
Before installing, servicing, or adjusting the belt cleaner/
tensioner, turn off and lock out/tag out all energy sources to
the conveyor and conveyor accessories according to ANSI
standards. Failure to do so could result in serious injury or
death.
DANGER
!
If this equipment will be installed in an enclosed area, test the
gas level or dust content before using a cutting torch or
welding. Using a torch or welding in an area with gas or dust
may cause an explosion resulting in serious injury or death.
WARNING
!
Before using a cutting torch or welding the chute wall, cover
the conveyor belt with a fire retardant cover. Failure to do so
can allow the belt to catch fire.
WARNING
!
Remove all tools from the installation area and conveyor belt
before turning on the conveyor. Failure to do so can cause

Before Installing Belt Cleaner
IMPORTANT
The delivery service is responsible for damage occurring in
transit. Martin Engineering CANNOT enter claims for
damages. Contact your transportation agent for more
information.
1. Inspect shipping container for damage. Report damage to delivery service
immediately and fill out delivery service’s claim form. Keep any damaged
goods subject to examination.
2. Remove belt cleaner assembly from shipping container.
3. If anything is missing contact Martin Engineering or a representative.
DANGER
!
Before installing, servicing, or adjusting the belt cleaner/
tensioner, turn off and lock out/tag out all energy sources to
the conveyor and conveyor accessories according to ANSI
standards. Failure to do so could result in serious injury or
death.
4. Turn off and lock out/tag out energy source according to ANSI standards
(see “References”).
DANGER
!
If this equipment will be installed in an enclosed area, test the
gas level or dust content before using a cutting torch or
welding. Using a torch or welding in an area with gas or dust
may cause an explosion resulting in serious injury or death.
5. If using a cutting torch or welding, test atmosphere for gas level or dust
content. Cover conveyor belt with fire retardant cover.
IMPORTANT
Center the belt cleaner blades to clean an area narrower than
the conveyor belt width. This allows for side-to-side
movement of the belt and prevents damage to the belt edge.
NOTE
The chute wall that the tensioner will be located on is referred
to as the “operator side.” The other side of the chute is
referred to as the “far side.” (If installing dual tensioners, side
that is most accessible is “operator side.”)
6. Determine which side of chute is easiest to access. Locate the tensioner
on the most accessible chute wall.
