It is very important that the driving and driven pulley grooves are in line and both pulley shafts are parallel,
see above, if the pulley faces are not parallel use appropriate size distance pieces to ensure belt grooves are
correctly aligned. Check belt tension by method below.
When fitting new belts spin drive by hand for 3-4 revolutions, taking care not to trap fingers. Tension belts to
1.25 setting forces see table 1. Run drive under load for 15-20 minutes. Stop and check tension reset to basic
value. If problems are experienced with belts turning over the 1.25 setting force may be maintained.
