valve. The hydraulic unit is controlled, with air trigger, from the tool.

Internal relief valves are pre-set at the factory for the protection of operator and equipment. External relief valves control PULL Pressure and RETURN Pressure.

Pressures are adjustable to match Huck installation tool being used. See applicable installation tool manual.

Hydraulic fluid is stored in a reservoir. Hydraulic quick disconnect couplers are furnished for connecting installation tool.
