7-9 V-belt tension
￭ Replace the old belts with the new V-belts after the first 25 operating hours.
￭ The best tension for a belt drive is the lowest possible, where the belt under
full load does not slip.
￭ A rough value for this is when the belt deflects 10 ㎜ when pressed with thumb
pressure between the two pulleys.
