TROUBLE SHOOTING:
FAULT CAUSE REMEDY
Foot pedal
will not
raise
platform. Air in hydraulics. Press and hold lowering pedal and
operate foot pedal twenty times.
Release lowering pedal.
If fault
remains. Release plunger
remains in (causing
release ball to not
seat properly). Check that release plunger is not
stuck, if so lightly lubricate and attempt
to operate pedal.
Check release plunger is not damaged
or deformed and jammed. Attempt to
straighten if necessary.
If fault
remains. Table overloaded Check weight of load is within table
capacity.
If fault
remains. Oil level low. Check oil level and top up if necessary.
DO NOT OVERFILL (see directly
below).
If fault
remains. Insufficient air in
reservoir (oil level
too high). Remove reservoir cap, remove excess
so that oil level is no higher than 8mm
below the bottom of the filler tube,
operate pedal to raise platform to full
height and replace cap.
If fault

lower the platform.
Whilst holding release pedal apply
additional load onto the platform to aid
its descent.
If fault
remains. Flow control
cartridge valve is
jammed. Unscrew hose connection, remove
flow control cartridge and check that its
plunger is still movable.
