Hunter L494 - Regular Maintenance; Corrosion; Maintenance Schedule

5.Regular Maintenance
With due care and maintenance, your Hunter alignment lift can last indenitely. Please use the following maintenance
schedule to keep your Hunter alignment lift in good working order.
5.1.Corrosion
NOTE
Scratches to powder-coat should be touched up as soon as possible, on an as-needed basis. Use provided
paint.
CAUTION
Wire ropes are a high wear item and must be inspected regularly to prevent failure. They MUST be replaced at
the rst sign of any symptoms listed below. The complete set MUST be replaced every 20,000 cycles or every
six years unless earlier replacement is indicated by the required service inspections (see the maintenance
schedule following).
The best preventive maintenance against wire rope corrosion is to keep the wire ropes well lubricated. The oil prevents
moisture from entering into the wire rope strands. Once salt and moisture have penetrated into the core of the wire rope
they are very dicult to displace and corrosion will begin immediately. The best method to prevent early replacement of
wire ropes is to keep them well oiled.
The following are specic signs to look for when inspecting wire ropes for corrosion:
• More than surface rust on exterior of the wire rope is unacceptable. In other words, if you can’t remove the rust easily
with a wire brush, it’s too deep and the wire rope should be replaced
• Any pitting of the wire rope indicates unacceptable amounts of corrosion. The wire rope should be replaced.
• Loss of exibility of the wire rope is unacceptable. This can be checked with the lift raised and set on the locks. If found,
the wire rope should be replaced.
• If any wires are broken, the wire rope should be replaced.
• Any “necking” or reduction in cross sectional area of the wire rope indicates a problem and the wire rope should be
replaced.
NOTE
If an area of the wire rope has no lubricant on its surface, the wire rope is rust bound and should be replaced.
Once the wire rope has lost oil protection, moisture has already entered the core and is nearly impossible to
remove.
