2 Tighten the Belt
1.
By hand, thread the spring trolley nut on the threaded shaft until it is finger tight against the trolley. Do not
use any tools.
2.
Insert a flathead screwdriver tip into one of the nut ring slots and brace it firmly against the trolley.
3.
Tighten the spring trolley nut with an adjustable wrench or a 7/16" open end wrench about a quarter turn
until the spring releases and snaps the nut ring against the trolley. This sets the spring to optimum belt
tension.
