Serious injury or death by electrocution can result if the machine or attachments are not kept a safe distance from electrical power lines.Keep the distance at least 3 m (10 feet) plus an additional 10 mm (.4 inch) for each 1,000 volts over 50,000 volts. For safety, local or state codes or jobsite operating directives, may require a greater distance.Never swing a load over a truck cab or workers.
When swinging into a ditch, do not use the ditch to stop the swinging motion. Inspect the machine for damage if the boom is swung into a bank or an object.Repeated stopping by an object can cause structural damage if the boom is swung into a bank or an object.With certain boom - stick - bucket combinations, the bucket can hit the cab or front of the machine. Always check for interference when first operating a new attachment.Whenever the tracks of the machine raise off the ground while digging, lower the machine back to the ground smoothly. DO NOT DROP OR CATCH IT WITH THE HYDRAULICS. Damage to the machine can result.Keep the stick out, when moving a clamshell machine, to prevent the bucket from swinging into the cab. The clamshell can swing in all directions.
Know the location of buried cables. Mark them clearly before digging.Consult your Caterpillar dealer for special bucket tips available for use in severe applications. Move the machine whenever the digging position is not efficient. The machine can be moved forward or backward anytime during the operating cycle.To work in and out of close places, utilize the bucket, or other attachment to push or pull the machine, or to lift the tracks.Use smooth, comfortable speeds while operating.For efficient operation, use more than one control at a time when possible.Spot a truck so the machine can load it from the rear or side. Load trucks evenly to avoid overloading the rear axles.An oversized bucket or one equipped with bladetype side cutters, should not be used in rocky material. It slows down the cycle and damage to the bucket and other components could result.Backhoe Operation
Digging
1. Position the stick at a 70° angle to the ground. 2. Position the bucket cutting edge at a 120° angle to the ground. Maximum break out force can now be exerted with the bucket. 3. Move the stick in and keep the bucket parallel with the ground. 4. If the stick travel stops due to the load, adjust the depth of cut by raising the boom and closing the bucket.5. To apply the greatest force at the cutting edge, down pressure must be decreased as the stick moves in.6. Maintain the bucket parallel with the control stick so that it ensures a continuous flow of material into the bucket.7. Continue the pass with the bucket traveling in a horizontal direction, peeling material into it. 8. Close the bucket and raise the boom at pass completion. 9. Engage the swing control when the bucket is clear of the excavation. 10. To dump, move the
