E. Wear Pad Inspection
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 will vary depending upon vehicle
use, weight of loads, operating conditions, and the location of boom pads
inside the boom.
If the vehicle is used continuously and 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 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.
