D. Wear Pad Check (50 Hour Intervals)
Visually inspect boom wear pads between the boom
sections at the rear and front of the boom for excessive
wear at every 50 hour interval.
The average expected life of boom pads can vary depend-
ing upon vehicle use, weight of loads, operating
conditions, and the location of boom pads inside the
boom.
If the vehicle is used continuously or the weights of the
loads are at or near maximum capacity, or if you are
operating in very dusty or dirty conditions, the boom pads
will wear much faster. The pads that are under the most
stress from the weight of the load will also wear faster
d. Measure the chain sag. Acceptable boom
chain sag is between 1-1/2" (38,1 mm) and
2-1/2" (63,5 mm). If the chain sag is less
than 1-1/2" (38,1 mm), repeat Steps “a”
through “d.”
e. Replace the rear outer boom cover.
C. Chain Lubrication (1000 Hour Intervals or Annually)
With the boom fully extended, apply "LPS - 3" or "LUBRI-
PLATE" chain and cable fluid or equivalent to the two
extend chains.
