Adjustments for the deceleration or cushioning of the index

table lift/lower cycle are provided on both of the index lift air

cylinders. There are two cushion adjustment screws on

each lift cylinder. The adjustment screw located on the bot-

tom is used for the retraction (lowering) of the cylinder pis-

ton, while the adjustment on the top is used for the exten-

sion (raising) of the cylinder piston. On some models the

adjustment is made using a small blade screw driver, on

other models the adjustment is made using a 5/32” allen

wrench. Be aware, these adjustments are very slight, per-

haps only 1/8 turn to achieve the desired result. Turning the

adjustment screw in a clockwise direction will increase the

cushion effect while turning the adjustment screw in a coun-

terclockwise direction will decrease the cushion. (See illus-

trations at the right)
