The boom slider is essential for the safe operation of the
machine. As a friction pair will develop between each
slider and the telescopic boom surface, improper slider
gaskets or continued use of extremely worn sliders may
result in component damage and unsafe operation. It is
recommended to check the boom slider thickness once
a year or after 1000 hours of operation.
1. Remove the cover plate from the head of the main
boom (near the turntable) or the nylon brush at the
tail of the main boom (near the platform).
2. Measure the thickness of each slider at the head
and tail of the main boom.
3. If the telescopic cylinder has sliders, measure the
slider thickness after the telescopic cylinder is
removed.
4. Compare the measured thickness value of each
slider with the value specified in the above table,
and replace the slider assembly in time if the wear
extent of the slider is greater than or equal to 3mm
(0.118in).
NOTICE
The disassembled slider cannot be reused and must
be replaced with a new slider assembly.
