Product questions and answers
Is the full height range a single hydraulic stroke?
No. The description lists piston height and head-screw adjustment separately. Do not treat the complete 10-3/8 to 20 inch range as powered piston travel.
Can this jack start under a 10 inch lift point?
The listed minimum height is 10-3/8 inches, so a 10 inch starting clearance is below that specification. Check the complete contact arrangement before ordering.
Does the bypass valve replace a support stand?
No. Hydraulic protection does not establish permanent load support. Use the manufacturer's instructions and appropriate independent support for the work.
