– Optikrik Belt Tension Gauge & Components
To correctly tension belts using the Optikrik III:
Position the Optikrik in the middle of the longest belt runs on each of the belt circuits. Take care to
ensure that the indicator arm (A) is pushed down into the gauge body. Align the gauge so that its body
is parallel with the sides of the belt.
Push down on the pressure pad (C)
slowly and firmly with one finger. When a “click” is heard/felt, stop
immediately and remove the gauge carefully to avoid disturbing the indicator arm.
Read and turn the gauge sideways if required, to ascertain the exact point where the top surface of the
indicator arm (A) crosses the scale (E). This is the given belt tension.
Tighten or slacken the belts as necessary following the guidance below and repeat the process again
on the other two belt circuits.
