6.1 Important Notes About Wear Items & Maintenance
The following information regarding life of the wear items and service or adjustment intervals of the functional
elements are only GUIDELINES. Conveyors are application-speci c products whose life expectancy can vary
depending on their relative loads and speeds, and which can be signi cantly infl uenced by environmental factors.
• All moving components and screw connections should be checked every 6 months.
• All safety-relevant components should be part of a regularly scheduled weekly inspection
• The proper function of these components must be con rmed at all times.
• Do NOT operate conveyors if safety-relevant components are damaged or missing.
• All parts which contact the product should be cleaned weekly (example: belt).
• Remove heavy grease coatings with ethyl alcohol.
• Blow off debris from belts with structured surfaces using compressed air.

7 CONVEYOR BELT MAINTENANCE - TENSIONING & TRACKING
7.1 Standard Idler 17
General Remarks:
• Belts may need to be tracked due to shifting during shipping.
• Prior to delivery of the mk conveyor, the belt was tensioned and tracked at the factory.
• Belt tracking should only be done at the idler end.
• After a downtime of more than 2 hours, allow the timing belt to run for 5 to 10 minutes in normal opration
before making any adjustments.
• All timing belt rollers and supports roller must be clean. Replace damaged or heavily worn components.
• The teeth of the timing belt pulley must always positeively engage with the timing belt.
• Avoid over tensioning the belt, increase slack in belt if necessary (see image below).
• Avoid under tensioning the belt, belt and pulley teeth must be proprely engaged (see image below).
All work to be performed by quali ed personnel only.
Conveyor power must be disconnected before replacing the belt.
Example: Over tensioned belt Example: Under tensioned belt
