E. Wear Pad Inspection
(Boom)
(50 Hour Intervals)
Visually inspect the boom wear
pads between the boom sections at the rear and front of the boom for excessive
wear.
The average expected life of the wear pads will vary depending upon vehicle use,
weight of the loads, operating conditions and the location of the boom pads inside
the boom.
If the vehicle is used continuously and the weights of the loads are at or near
capacity, or if you are operating the vehicle in very dusty or dirty conditions, the pads
will wear much faster. The pads that are under most stress from the weight of the
load will also wear faster than other pads. For example, the lower pads at the front of
the boom and the upper pads at the rear of the boom are under more stress than
pads attached to any other surface of the boom. Consequently, the lower pads at
the front and the upper pads at the rear will require service more often.
F. Wear Pad Replacement (Boom)
(As Wear Pad Indicators Indicate)
Each boom wear pad (1) is manufactured with a convenient wear pad indicator. This
is the angled cut (2) at each end of all wear pads.
