Troubleshooting
NOTE
Conveyor equipment such as conveyor belt cleaners are subject to a wide variety of bulk materials
characteristics and often have to perform under extreme operating or environmental conditions. It is
not possible to predict all circumstances that may require troubleshooting. Contact Martin
Engineering or a representative if you are experiencing problems other than those listed in the
“Troubleshooting” chart above. Do not return the equipment to operation until the problem has been
identified and corrected.
Installation
checklist
If after taking the corrective actions suggested under “Troubleshooting” you
are still experiencing problems, check for the following:
Symptom
Corrective Action
Insufficient cleaning and
carryback.
• Tension of cleaner on belt is set too low or too high. Increase or
decrease tensioner setting.
• Blades are worn. Check blades and replace if necessary.
Blade wears only in the
center.
• Use a segmented style blade for crown pulleys.
• Consider narrowing the blade width to clean the middle of the belt.
Noise or vibration.
Tension is not sufficient or is set too high. Correct tension as
necessary. If this does not correct problem, blade urethane may not
match application. Contact Martin Engineering or representative.
High blade wear rate.
Tension of cleaner on belt is set too high. Reduce tensioner setting.
Unusual wear or damage
to blades.
Check belt splice(s) and repair as necessary.
Bent or broken mainframe
or support frame due to
blade slipping through.
If blades are worn to or past the wear line, replace blades. If blades
are not worn, check mainframe location.
Corrosion or chemical
degradation.
Blade urethane may not match application. Contact Martin
Engineering or a representative.
Installation Checklist
✓
Pre-Cleaner mainframe is proper distance from belt surface on both ends of mainframe and
parallel to the pulley shaft.
✓
Pre-Cleaner blade tip does not lie in path of material flow.
✓
Blades are centered on belt.
