INSTALLATION INSTRUCTIONS
E. HYDRAULIC INSTALLATION DETAILS
1. Locate the power unit, preferably within 10 feet of the lift cylinders (the lift is
supplied with a 10-foot connecting hose). The power unit can be mounted on the
floor or on the wall, contact the Autoquip Customer Assurance department if special
mounting brackets are required.
2. Fill the power unit with oil. Do not over fill! The oil level should be approximately 2”
from the top of the tank (See “Oil Specifications” in the General Maintenance
section). Wire in the power unit and remove any air from the hydraulic system.
3. Attach the hose from the power unit to the coupling on the back of the mast
(Reference Figure 20).
WARNING !
Use properly rated hoses only! Never use fittings or hoses that are
not properly rated for the intended use.
4. Connect electrical power to the power unit.
5. Remove any air from the hydraulic system per the “Bleeding Air from the System”
instructions found in the General Maintenance section. Do not operate the lift yet!
CAUTION!
Purge air in the system! The presence of air in the system can lead to
a lock-up of the velocity fuses. (Air reacts like a spring when it is
compressed.)
6. Adjust the top stop bolts that are provided into the stop angle located at the top of
the mast pair to make contact with the carriage overhead channel when in the fully
raised position (Reference Figure 16).
WARNING !
Do not over travel! Mechanical stops must be in place to prevent the
carriage from over traveling. Over-traveling can cause permanent
damage to the carriage or failure of the lifting cables.
