MACHINE OPERATIONS AND CONTROLS 3.3.8 PROHIBITED OPERATIONS 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. RYA02270 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. RYA02280 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. 118 WARNING
