Reconditioning instructions
Raise the lifting mechanism to the highest position.
Wipe the lifting column of dust and dirt with a dry cloth.
Then lubricate the lifting column using a thin layer of Teflon
or silicone-based grease.
Check that the seat is facing straight ahead relative to the
base. Check that the lifting mechanisms' attachments to the
seat frame and base are properly tightened. Replace screws
that have damaged key handles or threads.
Check that the lock ring under the bottom is securely fastened.
Check that the gas spring locks properly and that the height
does not slowly change under load. If the height slowly
changes under load, adjust the wire nipple. Check and
replace damaged wires and sheaths.
Check all welds carefully for signs of cracks, corrosion
and movement. Ensure good lighting and preferably use a
magnifying glass, as small cracks can be difficult to detect
on black lacquered bases. Make sure the base is stable. Fill
in any varnish damage with touch-up paint to avoid corrosion.
Check and tighten all screw joints. Replace screws that have
damaged key handles or threads.
Replace the brake feet. Check that the brake is working
properly.
Check that guide bushings and plastic plugs are properly
secured. Replace worn or damaged parts.
Check castors and jumpers for wear or play. Wear or play
may indicate defective bearings. Check that the castors
rotate well and the housings rotate. Replace worn or
damaged parts.
Check that the castors' screws are intact and tightened.
Replace screws that have damaged key handles or threads.
Carefully check all welded parts for cracks and paint
damage. Ensure good lighting and preferably use a
magnifying glass, as small cracks can be difficult to detect
on black lacquered structures. Fill in any varnish damage
with touch-up paint to avoid corrosion.
