5.3 Material Support Lift 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 Lifter Case
Open the Material Support Lift enclosure.
2. Locate the Air Cylinder
Locate the Material Support Lift air cylinder.
3. Adjust the Needle Valves
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.
Adjust the needle valves as needed. Screwing the needle valve in will slow the actuation,
screwing the needle out will speed up the actuation.
Bend-Tech recommends adjusting the needle valves incrementally, turning a half turn at a time
in order to avoid damaging the Material Support Lift.
