Prohibited Operations - Komatsu PC220LC -8 Operation & Maintenance Manual

MACHINE OPERATIONS AND CONTROLS

PROHIBITED OPERATIONS

If it is necessary to operate the work equipment control lever when the machine is traveling, stop the machine, then operate
the control lever.
If any lever is operated when the auto-deceleration is being actuated, the engine speed will suddenly increase, so be careful
when operating.
Operations Using Swing Force
Do not use the swing force to compact soil or break objects. This
is not only dangerous, but will also drastically reduce the life of the
machine.
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
If the work equipment is used with the cylinder rod operated to its
stroke end, and given impact by some external force, the hydraulic
cylinders will be damaged, causing personal injury. Avoid
operations with the hydraulic cylinder fully retracted or fully
extended.
