This manual provides detailed instructions for setting up, operating, and maintaining the Norco 72080A and 72090A 20-ton air/hydraulic floor jacks. It emphasizes safety precautions, including proper load centering, use on hard surfaces, and avoiding overloading or modifying the equipment. The manual also includes setup steps for assembling the handle and release valve, purging air from the hydraulic system, and operating procedures for lifting and lowering vehicles safely. Safety warnings and maintenance requirements are highlighted throughout.
The document includes important safety cautions, such as not using the jack in horizontal or angular positions, not exceeding 100 PSI air pressure, and never placing body parts between the saddle and load. It also specifies that jack stands must be used to support the load after lifting and that the jack must be stored vertically to prevent oil leakage.
Do not exceed 100 P.S.I. input air pressure.
The jack may be stored in its normal use position or in a vertical position to save space. Do not use or store the jack with the handle assembly end pointing or angling down.
Use hydraulic jack oil or turbine oil only.
