Setting Spring Tension

CAUTION

Do not overwind the Power Spring. Too much tension

reduces the life of the Spring.

To adjust tension on the Power Spring:

12. Add / remove one coil of hose to / from the Sheave

Assembly.

IMPORTANT: When the hose is fully extended

from the reel, the Power Spring should be a min-

imum of 1/2 turn from a fully wound condition.

13. Repeat step 12 until the proper tension is achieved.

* Which slots in the Sheave Assembly the U-Bolts are

installed depends on the mounting position of the reel. Refer

to section entitled Mount Positions for details.
