Adjusting Lifter Trigger Pause
The Lifter Trigger Pause should be enabled whenever the Material Support Lifter is in use. The
Lifter Trigger Pause should be set to a parameter longer than the retraction time or the Material
Support Lifter may hit the Rail.

Setting Material Support Lift Actuation and Retraction Adjustment
Material Support Lift Retraction is pre-set at the Bend-Tech manufacturing facility. The
retraction value is typically set to roughly two seconds. If it is determined the retraction time
needs to be adjusted the Operator will be required to open the Material Support Lift enclosure
and adjust the needle valves in the air cylinder.
1. Open the Material Support Lift enclosure.
2. Locate the Material Support Lift air cylinder.
3. There are two needle valves on the air cylinder. When facing the inside of the enclosure,
the needle valve on the left adjusts the retraction speed of the Material Support Lift. The
needle valve on the right controls the actuation speed of the Material Support Lift.
4. Adjust the needle valves as needed. Screwing the needle valve in will slow the actuation,
screwing the needle out will speed up the actuation.
