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” in this 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 Devices”.
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.
6.3.5 Up Stop Valve Adjustment
The up-stop valve is bolted to a mounting plate assembly that is permanently welded near the end of
the scissors leg on the clevis end of the lift. A mechanical plunger is located on the end of the valve
which, when depressed, blocks the flow of oil until physically released. An adjustable striker bolt is
mounted to a plate that is welded to the base frame, which is also at the clevis end of the lift. As the lift
travels upward, the scissors leg and up-stop valve assembly swings into the adjustable striker bolt until
the up-stop plunger is depressed and thereby blocking the flow of oil to the lifting rams. Once blocked,
any further oil pumped from the power unit will pass over the relief valve back to the tank.
Do not operate the power unit on relief for more than a few seconds.
When on relief, the valve will make an audible squealing sound.
The up-stop system can be adjusted to modify vertical travel by:
1. Loosen holding nuts on either side of adjustable striker bolt.
2. Screw adjustable striker bolt in towards plunger (to raise travel) or out (to shorten travel).
3. Retighten the holding nuts.
Setting the up-stop valve for travel beyond catalog limits will cause the lift
to fully raise against physical stops and, if the pump is allowed to
continue to run, cause irreversible damage to the lift structure.
