SOUTHWORTH
ZLS SERIES — FLOOR HEIGHT LIFT TABLES

• Check all of the hydraulic fittings and hoses, and
tighten the connections as necessary. Sometimes
the fittings can be worked loose by the vibrations
from the power unit.
WARNING!
If a hydraulic fitting becomes loose, or if a
hydraulic hose breaks, the hydraulic fluid may
escape from the system under pressure. If the
lift table is elevated when this happens, it can
drop quickly. Someone may be hurt, or the lift
or load may be damaged. Be sure all hydraulic
fittings are tight.
• The clear plastic vent line and the surface of the
cylinder rod should be free of hydraulic fluid. If
you find much fluid in either place, the cylinder
seals may be leaking. (It is also possible the tank
may be overfilled.) Contact the Southworth Parts
Department for instructions on repacking the
cylinder.
• Disassemble the down valve. Blow the valve
plunger clean with compressed air. Reassemble
and reinstall the valve.
• Drain and discard the hydraulic fluid. The suction
filter is in the tank, at the point where the suction
line runs out to the pump. Unscrew the hydraulic
line, then remove the filter. Blow the filter clean with
compressed air. Reinstall the filter in the tank and
reassemble the hydraulic line.
• Refill the tank with new hydraulic fluid.
CAUTION!
If you continue to use fluid after it has “worn
out,” the moving parts in the system will wear
more quickly.
• Be sure all of the warning labels are in position
and legible. The labels are shown in Figure 6.
The
warning labels are intended to protect your workers.
If the labels are missing, or if they have been painted
over, replace them.
