head pulley. On a dual-cleaner system, a 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, Secondary Cleaners can be installed alone. Multiple Pre-Cleaners
and/or Secondary Cleaners may be required to clean the belt. If the materialhandling 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

rules must be strictly followed when working on the belt cleaner.
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.
Before installing, servicing, or adjusting the belt cleaner, turn
off and lockout / tagout / blockout / testout all energy sources
to the conveyor and conveyor accessories according to ANSI
standards. Failure to do so could result in serious injury or
death.
Introduction
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.
Follow local confined space procedures.
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. Follow local fire watch
procedures.
Remove all tools from the installation area and conveyor belt
before turning on the conveyor. Failure to do so can cause
serious injury to personnel or damage to the belt and
conveyor.
Mainframe with blade can be heavy and may require two
people to lift. Attempting to lift the belt cleaner without
assistance could result in injury.

NOTE
Before Installation
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.
Before installing, servicing, or adjusting the belt cleaner, turn
off and lockout / tagout / blockout / testout 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 lockout / tagout / blockout / testout energy source according
to ANSI standards (see “References”).
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.
Follow local confined space procedures.
5. If using a cutting torch or welding, test atmosphere for gas level or dust
content. Cover conveyor belt with fire retardant cover.
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.
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.”)

Belt Width
Belt Width + 5 in. minimum
Before Installation
Figure 2. Chute Width Requirements
Inside chute width must be a minimum of belt width plus
5 inches to insure there is adequate space to install cleaner and
tensioner. If chute width is too narrow either the tensioner will
need to be spaced off of the chute wall or the mainframe can
be cut down. The mainframe can only be cut down if the blade
is belt width minus 6 or 8 inches.
6. Inspect belt cleaner mounting area for possible obstructions that could
interfere with proper mounting. Refer to following guidelines:
a. The cleaner can be mounted anywhere on the arc from +30 degrees to
-30 degrees from a center line parallel to the belt line as long as:
(1) The blade is not in the direct flow of discharging material causing
premature blade wear.
(2) The diameter of the pulley is big enough that the blade does not
trap or hold material between the inside of the blade and the belt.
(3) There is at least the equivalent of a 45 degree angle between the
blade and belt to prevent material buildup in this space.
b. Lack of service is the main cause of poor belt cleaning performance.
Follow CEMA guidelines for access:
(1) Clearance for service outside the chute must be at least equal to the
belt width.
(2) Cleaners must have service platforms. CEMA recommends
cleaners be mounted at least 24 in. (600 mm) above the work
platform.
(3) If the belt width is 54 in. (1400 mm) or larger consider access
doors on both sides of the chute.
c. Refer to “Installing Belt Cleaner and Tensioner” and “Part Numbers”
sections of this manual for specific mounting and cleaner dimensions.
