pulley primary cleaner such as the Martin 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.

The cleaner can be supplied or retrofitted with a variety of cleaning blades. These include:

• Tungsten Carbide—For very abrasive materials.

Materials Required

Urethane Shelf Life

Only standard hand tools are required to install and service this equipment.

Urethane put in service after exceeding it’s shelf life may wear differently and deteriorate quicker than normal urethane.

Code Date is written near bottom of blade as mm/dd/yy-x. In addition to or in place of this date, you may see an imprinted date medallion similar to the example shown. In this example, “14” stands for the year 2014. The small circles represent the quarter of the year. If three circles are “punched” the blade was produced in the first quarter. If none of the circles are “punched” the blade was produced in the fourth quarter. If code date on your blade(s) is not legible or is missing, contact Martin Engineering or a representative.

DANGER

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 from shipping container. Equipment in container should include the following:

• Martin

• Two Conveyor Products Warning Labels, P/N 23395.

• Two Pinch Point Warning Labels, P/N 30528.

3. If anything is missing or damaged, contact Martin Engineering or representative.

Martin Engineering M3699-03/16 3 Martin® DT2 Inline Cleaner XHD

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.

to ANSI standards (see “References”).

WARNING

NOTE

Before Installation

If equipment will be installed in an enclosed area, gas level or dust content must be tested before using a cutting torch or welding. Using a cutting torch or welding in an area with gas or dust may cause an explosion.

5. If using a cutting torch or welding, test atmosphere for gas level or dust content. Cover conveyor belt with fire retardant cover.

The chute wall where the tensioner with hitch pin will be located is referred to as the “operator side.” The other side of the chute is referred to as the “far side.”

6. Determine which side of chute is easiest to access. Locate the tensioner on the most accessible chute wall.

Installing Belt Cleaner

IMPORTANT

WARNING

NOTE

To install the belt cleaner, follow the procedures corresponding to the following steps:

If installation is to be done in an enclosed area, test atmosphere for gas level or dust content. Follow all welding and safety guidelines. Protect belt surface from weld splatter with appropriate shield.

For original equipment installation, where cleaner cutouts and brackets have been fabricated into the chute during construction, ignore steps 1, 2 and 3.

Read entire section before beginning work.

Installation

Locating Cleaner Centerline

Solid backing of the blade is essential to ensure proper operation and efficient cleaning. Install the cleaner adjacent to the head pulley or a flat pressure roller to obtain best cleaning results. See Figures 1a and 1b.

For installation on enclosed head pulley chutework, draw all dimension lines on chute wall. In applications where head pulley is not enclosed, use the best available field resources and/or methods to ensure that these critical dimensions are followed for a proper installation.

1. On the return side of the belt, locate the tangent point at which the belt leaves the head pulley. Measure a distance 2 in. (50 mm) and draw a line perpendicular to the belt at this point. See Figures 1a and 1b.

2. Note: For installation below pressure rollers, mark the vertical line 2 in. (50 mm) from the centerline of the roller. See Figure 1a.

3. This line represents the centerline of the Martin XHD and the cleaner mount brackets.

1. Using the previously marked line as the centerline, mark the chute cutout and mount hole locations as shown in Figure 2. Repeat on both sides of chute, ensuring the cutouts are accurately aligned with each other.

Note: The location of the mounting holes differs for air- or

spring-tensioned models, as well as for Martin

Inline or Reversing Blades. Make sure that you are using correct dimensions and verify cleaner position before proceeding.
