Martin Engineering M4082-01/22 1CleanScrape®Small Cleaner
Introduction
Introduction
General CleanScrape®is a Pre-Cleaner which is installed diagonally across the
discharge pulley and forms a three dimensional curve. The cleaner has a
matrix of tungsten carbide scrapers incorporated into the main rubber body
during the vulcanization process. It is tensioned against the belt at an
extremely low contact pressure. 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 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, at least one
Martin®Inspection Door should be installed. Martin®Inspection Doors are
available from Martin Engineering or a representative.

Safety All safety rules defined in the above documents and all owner/employer safety
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, 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.
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.
Follow local confined space procedures.
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. Follow local fire watch
procedures.
WARNING
!
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.
WARNING
!
Cleaner can be heavy and may require two people to lift.
Attempting to lift the belt cleaner without assistance could
result in injury.

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, 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”).
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.
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.
CAUTION
!
Ensure conveyor chute remains unplugged. A plugged
conveyor chute may cause cleaner to damage belt.
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.”
NOTE
The installation instructions in this manual are the preferred
methods for the most common installations. Contact Martin
Engineering for alternative installation options.
Before Installation

Martin Engineering M4082-01/22 4CleanScrape®Small Cleaner
Figure 1. Belt Cleaner Mounting Orientation
IMPORTANT
The CleanScrape®carbide scrapers are molded into the
rubber body of the cleaner at a slight angle creating a serrated
cleaning edge. For effective cleaning, the cleaner can only be
mounted in orientation shown.
6. Inspect belt cleaner mounting area for possible obstructions that could
interfere with proper mounting. Refer to following guidelines:
a. Ensure cleaner does not lie in path of material unloading from
conveyor belt.
b. The top side of cleaner should be no less than the 2 o’clock position.
Material could strike the back of the cleaner causing wear which will
lead to premature failure.
c. The ideal installation angle is 17°–18°. Installation angles of 15°–21°
are acceptable. Higher angles lead to increased wear on the blade.
d. Belt width must not exceed a ratio of 3:1 to the head pulley diameter.
For example, the maximum belt width for a conveyor with a 300 mm
(12 in.) head pulley is 900 mm (36 in.).
e. Chute walls must be strong enough to not flex as tension is applied to
cleaner. If chute wall flexes inadequate tension may be applied to
cleaner resulting in poor cleaning performance. Additional chute wall
structure support may be added to prevent chute wall from flexing.
f. The distance between the cleaner and the chute wall should be
minimized. Martin Engineering recommends keeping the distance to
150mm (6 in.) maximum per side (see Figure 4). Excess cable could
result in vibration that could damage the belt or the cleaner. If
necessary, build a sub-wall to support the tensioners in the proper
position. Consult Martin Engineering for installation assistance if
parameters fall outside of this range.
g. For typical installations, start with the bottom rope in the 6 o’clock
position. The exact positioning of the top rope is a result of the
installation angle.
h. For belts with low product flow, lower the top rope until cleaner is out
of material path. Cleaner angle must be 15° or greater.
Correct Mounting Position Incorrect Mounting Position
Before Installation

Martin Engineering M4082-01/22 5CleanScrape®Small Cleaner
7. Lack of service can contribute to poor belt cleaning performance. Follow
local 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. Cleaners should be
mounted at least 600 mm (24 in.) above the work platform.

IMPORTANT
The maximum distance between chute wall and edge of blade
is 150 mm (6 in.). Excess free cable causes too much vibration
resulting in damage to cleaner and components. If necessary,

IMPORTANT
Tensioners used with CleanScrape®Small Cleaners can be
installed on either the inside or the outside of the chute wall.
Tensioners are shipped with the inside mounting plate (E)
installed. If the application requires tensioners to be mounted
on the outside of the chute wall, the outside mounting plate (C)
must be used.
NOTE
Standard tensioner mounting location is on the outside of
chute wall.
1. Determine if tensioner will be mounted on the inside or outside of chute
wall.
2. If the tensioner will be installed on the outside of chute wall, the tensioner
mount plate must be changed as follows:
a. Remove nuts (F).
b. Remove inside mounting plate (E) from tensioner assembly (A).
c. Install outside mounting plate (C) on tensioner assembly.
d. Install and tighten nuts (F).

CAUTION
!
The correct mounting plate must be used or damage to cleaner
will result. Using the incorrect mounting plate results in cable
being cut by roller and ultimately cleaner failure.
