Check the tension of the fan belt
After working for 50 hours, perform the first
inspection. Check once every 100 hours
thereafter.
In order to ensure the normal operation of
the generator and the service life of the
belt, it is necessary to tension the fan belt
correctly.
For a correctly tensioned belt, apply 6kg
perpendicular to the belt between the fan
pulley and the generator pulley, and the
sinking amount for the belt is about
5-10mm.
If the belt is found to be damaged, it shall
be replaced.
