## DO NOT USE MACHINE WEIGHT FOR DIGGING OPERATION Do not use the machine weight to obtain power to dig. This could cause severe damage to the machine and its components. Before digging the hard bedrock, crack the hard bedrock into pieces by another method and then dig it. It will not damage the machine and result in more economical way. <!-- image --> ## OPERATING ON A SLOPE Use extreme caution when operating machine on a slope. The machine may become unstable and could tip or roll over. - · Place the crawlers parallel to the slope. - · Always swing the upper structure slowly when rotating it toward the downhill side with a load. The extra weight from the load may make the machine unstable. - · Be aware the weight of the upper structure could cause it to rotate when the machine stops on a slope. - · When the machine stops on the slope, lower the attachment to the ground on the downhill side of the machine and wedge the bucket into the ground if equipped. ## CALL BEFORE YOU DIG Confirm the local government or the public service company for locations of underground utilities of gas, water, phone, electrical power, and so forth before working in the area seemingly with these lines.
