RECOMMENDED MAINTENANCE
Regular maintenance will prolong the service of your mast
assembly. Follow this recommended schedule.
CAUTION Do not perform maintenance while the tower is
operating or energized.
Prior to beginning normal operation of the mast, check the mast
and lift system for any signs of damage or excessive wear. If
guyed, insure that all guy ropes are securely fastened. Also, verify
the height readout of the controller with the physical position of
the mast.
During routing operation, periodically verify the travel limit setting
and the accuracy of the position readout of the controller.
EVERY SIX MONTHS
Check the lifting rope and guy rope for signs of wear. A well
maintained rope and guying system will prolong the use of the
mast system.
Check to ensure that the rollers on the carrier assembly are
operating properly.
Inspect the components and tubing of the pneumatic polarization
mechanism for signs of corrosion, excessive moisture and wear.
Pneumatic tubing which appears to be brittle and worn from the
effects of UV radiation and inclement weather should be replaced.
