6.3 Belt Tension
This section gives a brief overview of how to properly adjust the tension of the drive belts of the
dissolution bath. To ensure consistent performance, follow the recommended steps below:
1 Check the drive motor belt tension (shorter belt) by running the stirring to 300 RPM. If the
belt is loose, you will hear and see the belt skipping. If it is to tight, you will feel
excessive vibration on the drive plate and on the vessel plate. Adjust the belt tension if
necessary by sliding the movable cog spindle towards the front to tighten or towards the
rear to loosen the belt tension.
2 Check the spindle belt tension (longer belt) by running the stirring to 300 RPM. If the belt
is loose, you will hear and see the belt skipping. If it is too tight, you will feel excessive
vibration on the drive plate and on the vessel plate. Adjust the belt tension if necessary
by sliding the movable front idler wheel towards the rear to tighten or front to loosen the
belt tension.
Drive motor and spindle tension adjustments
Tightening the drive belt will loosen the spindle drive belt and vice versa. Adjust the
drive belt first before adjusting the spindle drive belt for proper tension.
