6-3 Adjusting the Belt Tension
The belt Tension is adjusted to the optimum tension at the time of shipment from the factory.
However, as the belt is used,it becomes run in and may loosen around the machine pulley
and motor pulley . Use the following procedure to check the belt tension.
Place a gauge against the belt q, loosen the nut w, and then turn the nut e to move the slot
to the appropriate position so that there is 8 mm of deflection in the belt q when 9.8 N (1 kgf)
of pressure is applied.
The machine operating direction is counterclockwise when seen from the machine pulley
end.
