Drive alignment
1. Use a straight edge to check the alignment of the pulleys.
2. Check alignment of belt on idler pulley, it should be centered on the idler pulley. The belt tensioner’s idler
pulley is fixed in position, therefore, alignment must be obtained by adjusting the motor and propeller
pulleys.
3. If an adjustment is needed, remove the belt, then loosen the set screws in the pulleys and move them as
necessary to achieve proper alignment.
4. Remember to tighten the pulley set screws after making an adjustment.
5. Drive alignment is very important for long belt life and proper operation.
Installation now complete, reconnect power to the motor and install outlet or inlet guard.
