7.7 Tighten/slacken the chain
The chain will elongate by use. How fast this happens depends on the conditions of use.
Chains elongate the most after the machine has been put into operation for the first time.
•
Too low chain tension results in the machine making a noise at the tensioning wheel
and jerky product carrier movement.
•
Too high chain tension causes extra wear and may damage the bearings of the motor
reductor.
7.7.1 How to measure the elongation on the chain
1. Measure the stretch amount using a chain stretch meter.
2. Tighten the chain depending on the measured stretch (or ’elongation’).
WARNING
•
When the chain has become 2% longer, the chain must be replaced soon.
•
When the chain has become 3% longer or more, the chain must be
replaced immediately.
WARNING
When replacing the chain, also replace the chain in the trolley (7 links).
