To increase spring tension:

Adding wraps of hose will increase spring tension. This can be accomplished by pulling out approximately 10 feet of hose, hand feed hose back up through roller bracket assembly* until the loop is large enough to slip over sheave. Add two or three wraps until desired tension is achieved. Do not exceed spring capacity.

To reduce spring tension:

This can be accomplished by removing wraps of hose from the reel sheave. Remove wraps of hose from the sheave, one wrap at a time, until desired tension is obtained.
 
 
2.How do I install a new drive spring and set pre-turns?
 
We have several different types of spring driven reels. Each require a slightly different set of instructions. For "How-To" instructions on replacing a drive spring please have your reel model or drive spring number available and consult customer service for instructions.
For how many wraps of "pre-tension" to put on the reel, please reference the chart below.
 
3.Can my spring driven reel be made "constant tension"?
 
While most JARCH spring retractable reels can be made "constant tension" at the factory or by simply removing the latching system there are some models that may not have this capability.
Please contact JARCH Customer Service to assure that the specific reel you have or require is capable of or available as a "constant tension" model.
