Prevent serious injury or death.
Never go under lift platform until load is removed and scissors
mechanism is securely blocked in raised position with maintenance
devices and hydraulic pressure is relieved.
The VF/FC is attached to elbow fitting in rod port of cylinder. Do not use a
swivel fitting between VF/FC and cylinder. If VF/FC is installed improperly,
it will not protect in the event of a hydraulic line failure.
1. Arrow on VF/FC indicates direction of oil flow
restriction. VF/FC must be installed with arrow
pointing away from cylinder.
Do not use Teflon tape
on hydraulic threaded
connections. Tape fragments may
damage hydraulic system.
Autoquip recommends replacing
any NPT fittings that have been
disassembled due to their inherent
design for sealing.
2. Apply Loctite PST #567 pipe thread sealant or equivalent to threads and install fuse to cylinder with
arrow pointing away from cylinder. Tighten fuse.
3. Fill reservoir to full mark if necessary with proper oil.
4. Check all fitting connections for hydraulic leaks and tighten as necessary.
5. Bleed air from system. See
“Bleeding Air From System” section.
6.3.4 Hose Orientation
To prevent damage to cylinder hoses, it is necessary to establish a correct hose shape and pattern of
movement as follows:
1. Raise lift to its full height and block securely.
See “Maintenance Device”.
2. Install one end of new hose to cylinder fitting.
3. Since hose is fixed at both ends, it is possible to put a twist in hose that will allow it to follow the same
pattern each time lift is operated. This twist will allow hose to travel about half way between cylinder on
right side and inner leg on right side.
4. Lower lift carefully and verify hose is free and clear of cylinder and inner leg assembly. If not, twist
hose in direction necessary to clear any obstruction and tighten swivel fitting.
