TROUBLE SHOOTING
PROBLEM
SUGGESTION
Pumping pump handle but won’t lift
patient.
Pump arm very hard to pump.
Patient is in the standing position, but
slowly goes down.
Tried to tighten knobs for any of the
adjustments, won’t stay tight, or
knob won’t stay in.
Check that release lever isn’t held
down, lift lever up, try again. Check
Jack for leakage, jack is out of fluid.
Jack lobe needs to be re-adjusted.
Check lift linkage / lift arms, making
sure there is nothing stopping the
lifting motion. May need to release
pressure.
May be pumped to maximum exten-
sion
Readjust the Jack lobe. Lift up on
release handle. Replace jack.
Stripped threads, try to re-tap, if
that doesn’t work you may have to
tap the hole out to 3/8-16 and try
3/8” knob.
“Warning”
When pumping the jack handle back and forth please be sure the lift arms have enough
clearance to go under the table pad. By not doing so you may rip or tear the upholstery of
the table pad. (see below)
