F & K Balance Adjustment Instructions

Balances sashes and adjusting balances

Try the sashes up and down TO THE LIMIT OF THEIR TRAVEL. If there is a tendency for either sash to drop when in the up position, adjust the balances as follows:

Disconnect balance foot attachment from pivot shoe (or kit), a screwdriver can now be inserted in the slot in the ratchet fitting at the bottom of the balance (see Fig. 24). Adjust by turning the ratchet in an anti-clockwise direction as viewed from underside (see Fig. 24). Two ‘clicks’ of the ratchet equal one complete turn. Ensure that the same number of turns are applied to each balance pair.

Two turns maximum would be required ONLY if necessary and sash is not holding correctly. Please make sure you only turn in an anti-clockwise direction. When the balance is tensioning you will hear it click on every turn. Do not over tension otherwise it will break the spring. Weight guidance is printed on text of tube.

Don’t tension balances more than necessary.

Do keep the foot attachment tight into the sash and make sure that the covers of the fitting.
Do not rub the jamb when the sash is moved.
