Drive belt, check and change

Stop the engine before doing any maintenance work.
Check belt tensions and condition regularly. A belt that
is tensioned too tightly may damage bearings, while a
belt too-loosely tensioned may slip.
Check and adjust the belt after operation, while the belt
is still warm.
A correctly-tensioned belt should be possible to
depress approx. 10 mm (0.4") between the pulleys.
