Description
1 50’ length of 3/8” low pressure rubber tubing
3 20’ lengths of 3/8” high pressure wire braided hose & misc. fittings
1. Locate the power unit behind the lift or beside either mast beam (the lift is
supplied with an extra 20-foot connecting hose for the cylinder furthest away from
the power unit – if required). 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. Plumb each lifting cylinder as show in Figure 26, taking care to note correct
orientation of the velocity fuses (arrows are stamped on the side of the fuse to
show the direction of the flow you are trying to control).
WARNING !
The velocity fuse (VF) must be properly installed! The VF is attached
to the elbow fitting in the rod port of the cylinder. If the VF is installed
improperly, it will not lock the carriage in place in the event of a
catastrophic hydraulic line break!
WARNING!
Attach velocity fuse with solid fitting! Do not use a swivel fitting
between the velocity fuse and the cylinder. If accidentally broken at
the swivel, the velocity fuse will not prevent the carriage from falling
to the floor.
3. Attach the high pressure, braided hoses from the high pressure port of the power
unit to the cylinders as shown in Figure 27.
WARNING !
Use properly rated hoses only! Never use fittings or hoses that are
not properly rated for the intended use.
4. Cut the required lengths of 3/8” low pressure, rubber bleeder tubes and connect
from the reservoir of the power unit to the cylinders as shown in Figure 27.
