the ignition key before starting the

NOTE!
Inspect new belts constantly for the
first 20 working hours and adjust
tensioning as necessary following the
instructions above. Use this procedure
each time you attach new belts to the
machine.
Correct tensioning can extend belt life
and reduce downtime.
The best tensioning is that point
where the transmission is at the lowest
tension without the belt being skid. An
under-tensioned transmission causes
wear and friction overheating.
