Speed Control
Speed change is effected by manual movement of the belt on the pulley. 33.5 RPM on the small diameter step on the pulley, 45
RPM on the larger diameter step on the pulley.
Installing the Belt
Start with the belt around the motor pulley, take care the other end clears the centre spindle and rotate the platter, the belt will track
around the platter. See Fig (14). Well Tempered Lab belts if dropped are easily misplaced, we give you two but suggest you place
the belt on something dark to make it easily seen.

Belt for Life Policy
The Well Tempered Lab offer a "belt for life policy" just send a self addressed envelope with stamp to your distributor or dealer for
replacement.
Speed adjustment
This is factory set, but if required, this can be achieved by carefully adjusting the small screw adjacent to the DC socket.
