My series 751 won't work!

Regarding my recent order with SWISCO. I installed the 751 channel balances and I cannot get them to work. When I put the sash in the window and lower it to the shoe, the shoe remains in the locked position. Pushing the sash down farther only causes the shoe to be locked in a lower position in the channel. I have tried unlocking the shoe with a screwdriver and bringing it up to the sash but lowering the sash continues to lock the shoe in the channel. When I close the window completely the shoes will remain at the bottom of the channel. I have also looked at the cam pivots and replaced the mangled ones. I have three more windows to fix but I won't until I figure out what is going wrong. Thanks for whatever help you can provide.

Thanks for your response. I was able to also find this answer to my question in your discussions archive.

Success! Four channel balances replaced and the sashes are functioning as they should. One install note that should be pointed out as a supplement to the install video, the knife lock points need to be pointing inward to function properly. I made the mistake and then corrected. Thanks for all of your help.

I agree with 'a handy person from NJ' that it would be helpful if the video mentioned turning the points in towards the house. My windows work very well now and it cost me much, much less than a previous quote from a local window parts dealer. Thanks, I will use you again for other projects.
