3.3.8 PROHIBITED OPERATIONS
WARNING
• Do not attempt to operate the work equipment control lever, while the machine is traveling.
•
Operations Using Swing Force
Do not use the swing force to compact soil or break earth
mounds or walls.
When swinging, do not dig the bucket teeth into the soil.
These operations will damage the work equipment.
•
Operations Using Travel Force
Do not dig the bucket into the ground and use the travel
force to carry out excavation. This will damage the machine
or work equipment.
• Prohibition of Operations Using Hydraulic Cylinders to
Stroke Ends
When operating the cylinder, do not operate it to the end of
its stroke. Always leave a small margin.
If the cylinder is operated to the end of its stroke, force will
be brought to bear on the cylinder, and this may cause dam-
age to the pins, boom, arm, and frame.
•
Digging Hard Rocky Ground
It is better to excavate hard rocky ground after breaking it up
by some other means. This will not only reduce damage to
the machine but make for better economy.
