7 Troubleshooting


7.2 Troubleshooting

If, after the installation, there is an abnormally high wear and tear onthe cleaner blade and/or the cleaning efficiency is too low, check thefollowing points:

NOTEThe secondary cleaner is subject to many different types of bulkmaterials and is often used in extreme working and environmentalconditions. Therefore faults can occur in addition to those listedhere.In this case, Martin Engineering or a representative can help withthe positioning or customized solutions. Use the conveyor beltsystem only after the fault has been identified and rectified.

Symptom Cause Corrective action

High wear and tear on the cleaner blade.

The tension of the scraper against the conveyor belt is too tight.

8.1 Storage

To maintain optimal functionality, Martin Engineering recommendsstoring the cleaners and the cleaner replacement blades made ofurethane or with rubber components at room temperature and pro-tected from direct sunlight.

Depending on the type of urethane and the storage conditions, stor-age of between 6 and 12 months or longer under unfavourable con-ditions can degrade the functionality of the cleaner or cleanerblades.

The best conditions for storage are at a temperature of +0°C to+30°C and 60% relative humidity.

8.2 De-installation

De-installation is the reverse of the installation (refer to section4.2.2., page 16).

8.3 Disposal

Assemblies and/or component parts of the Martin Engineering brushcleaner should be disposed of properly after use.

• Complete assemblies should be de-installed andseparated according to material and disposed of.

When disposing, all national and international waste disposal regu-lations have to be observed.
