We assume that you have tilt windows using Series 600 red tip balances. If so, you might only need to add tension to the spiral using the 75-006 charging tool. You might also want to add some 3 in 1 oil to the spirals to loosen them up. Eventually, a balance replacement will be needed, but you can head it off for a while. See our media guide on charging the balances: |
