5. Do not use the weight of the base machine to pry
earth as illustrated.
Doing so will damage the base machine and may
cause personal injury.
6. Machine stability is greater when the load is posi-
tioned parallel with the tracks.
Machine stability is reduced when the load is swung to
the side and when operating the front attachment
perpendicular to the tracks.
Sudden stop of boom lowering movement is espe-
cially likely to cause tipping over.
When working on weak/soft surfaces or when loading
high-density materials, operate the machine at re-
duced bucket loads.
