Symptom
Handle mounting holes loosening or
enlarging.
Jack lowers with patient suspended.
Jack fails to lift to full height.
Oil leaking from around piston.
Oil leaking around rim of top cap.
Unit will not lower.
Action
• Periodically oil the pivot point.
• Check to make sure the pressure release
knob is completely closed.
• Check valve not sealing. Pump handle
rapidly several times, then open pressure
release knob and pull down on boom.
Repeat two or three times.
• Release cartridge defective– lay jack on
its side. Remove pressure release knob
cartridge and clean or replace.
• Air in oil under ram– pump unit up as far
as it will go. Open pressure release knob
and pull down on boom to lowest posi-
tion. Repeat until lift raises to full height.
• Unit may be low on oil– remove jack
from lift, collapse ram. Remove socket
screw (located on top of top cap) and
put 1oz. of #10 weight hydraulic oil in at
a time until the jack ram moves the
proper distance.
NOTE– Proper amounts of oil for a jack when com-
pletely empty are 7 3/4 oz. for 12" stroke; 11 1/2 oz.
for 17" stroke; 3 3/4 oz. for 6" stroke; 12 1/2 oz. for
19" stroke.
• Tighten packing nut.
• After use, seal should assume proper
shape. If oil continues to leak, clamp jack
base in vise with unit vertical; remove
top cap and replace quad ring located in
top cap. DO NOT loosen or remove reser-
voir tube from base as this will break seal
around base, causing loss of oil in unit.
• Lay jack on its side. Remove and clean
release cartridge making sure small
holes are cleaned out with pin or small
diameter wire.
• Replace release cartridge.
