Yanni Report post Posted November 12, 2014 My Adler 269-373 came with a pneumatic attachment as pictured. Can i buy one of these and make it work? https://www.college-sewing.co.uk/KHM-700-1H-HEEL-ACTION-AIR-TREADLE-ROD Thanks Yanni Quote Share this post Link to post Share on other sites

gottaknow Report post Posted November 13, 2014 A word from the wise. The aftermarket pittman rod air switches aren't that great. I would use a foot pedal air switch which would go right where the chain lift pedal is/was. That way you're not going to hit your footlift accidently while moving your treadle back to the brake/neutral position and you don't loose any positive feel between your treadle and your motor. On a flatbed, I prefer the knee lift air switch. Works like an old school knee lift, but with an air switch. Regards, Eric Quote Share this post Link to post Share on other sites
Yanni Report post Posted November 13, 2014 (edited) Where can I get a knee lift air switch or a pedal one from? I've got an efka servo motor installed so unlike in a clutch motor there is no stop on the heel press. Thanks.

gottaknow Report post Posted November 13, 2014 One of our sponsors here might have access to them. I buy from Universal Sewing Supply. They have an online catalog. Even with a servo motor, I prefer a separate air switch. Regards, Eric Quote Share this post Link to post Share on other sites
SARK9 Report post Posted November 15, 2014 I have set up one of my Juki machines with an air-actuated foot lift....built mostly using off-the-shelf parts. If you adjust the heel stroke on your foot pedal somewhat generously, its not particularly snarky about accidentally engaging it. Poor video of the action here: -DC Quote Share this post Link to post Share on other sites
Gregg From Keystone Sewing Report post Posted November 17, 2014 (edited) I think the foot treadle switch is the way to go, still, and like said, the quality is not the best in the history of sewing, but I sell the same item offered here and make it work no problem. Only one's I've seen that are better are sold here in the states, and I have some good used ones, but I really do use the same same as what you are showing from College, they work and are not bad, and have flow control valves installed as well, so you can control cylinder speed so it's not going to hammer up and down when moving.
