BAR-PULLER 2B1421 - Caterpillar

Tips For The Operator
An oversize bucket or one equipped with blade type side cutters, should not be used in rocky material. It slows down the cycle and damage to the bucket and other machine components could result.Warm up machine starting slowly. Engine and hydraulic oil must be warmed up before starting operations. Refer to Before Starting.Get the proper tooth angle and then scratch until the teeth finally bite in.Spot truck so machine can be loaded from the rear or side. Load trucks evenly to avoid overloading rear axles.Dump the spoil back from the edge of the trench to avoid spillage and to provide working surface.Use smooth comfortable speeds while operating.For efficient operation, use more than one control at a time when possible.When traveling uphill - or on a slope - keep the heaviest part of the machine on the uphill side.When swinging into a ditch, do not use the ditch to stop swinging motion.When dumping, open bucket and move stick out in one smooth motion.Maximum operator comfort can be obtained by using the hydraulics smoothly.Whenever the tracks of the Excavator raise off the ground when digging, lower the machine back to the ground smoothly. DO NOT DROP OR CATCH WITH THE HYDRAULICS.
Keep boom at least 10 feet from all overhead wires.
Repeated chopping can cause structural damage. Use a digging, scratching or peeling motion when trying to penetrate rock, frozen ground or hard surfaces. Use of a specially designed bucket or bucket attachment should be considered.
Digging
1. Position stick at about a 70° angle to the ground. 2. Set bucket cutting edge at about a 120° angle to the ground. Maximum break-out force can now be exerted with the bucket. 3. Move stick in and keep bucket parallel with the ground. 4. If stick travel stops due to load, adjust depth of cut by raising boom and/or curling bucket. 5. Down pressure on the bucket must be relieved, as stick travels, so force can be applied to the cutting edge. 6. Continue the pass with the cutting edge traveling in a horizontal direction, peeling material into the bucket. 7. Lift out bucket at pass completion. (Engage two speed control pedal for additional hoisting speed.) 8. Engage swing-stick control as soon as bucket is clear. 9. As boom approaches proper dumping height, engage swing-stick and bucket-boom controls.10. Continue making trenching passes with the stick working in position from 70° to 110°.11. Clean up trench at final depth to minimize hand labor.Moving
Movement of tracks and other operations can be accomplished simultaneously by feathering the travel pedal, while using other controls. 1. Move the machine whenever the digging position is not efficient. The Excavator can be moved forward or backward anytime during the operating cycle.2. Utilize the bucket or other attachment to push or pull the machine, or lift up the tracks, in order to work in and out of close places.
Reduce throttle when maneuvering in tight quarters or when breaking over a rise.When traveling any distance, engage the swing lock pin while
