3. Regular Maintenance
W
ith due care and maintenance, your Hunter alignment li can last indenitely. Please use the following maintenance
schedule to keep your Hunter alignment li in good working order.
3.1. Corrosion
The best pr
evenve 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 inspecng 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 ping 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 li 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 reducon in cross seconal area of the wire
rope indicates a problem and the wire rope should be replaced.
3.2. Maintenance Schedule
M
aintenance is to be performed by shop employee or trained li service personnel.

meeng original manufacturer specicaons.
