BRACKET AS 6W1203 - Caterpillar

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 stick out and open the bucket in one smooth motion.Lifting
There may be some local governmental regulations regarding the use of excavators to lift heavy objects. Please consult your CAT dealer regarding these regulations.
Do not exceed the rated load capacity of the machine. If the machine is not on level ground, load capacities will be reduced.Use a short sling to prevent excessive load swing.
Damage to bucket cylinder, bucket or linkage could result if slings are placed incorrectly.
Use the lifting eye on the back of the bucket to lift object. Lifting capacities are calculated from this point. Adjust to this accordingly.If the lifting eye at the bottom of the bucket is used, the connection must be made by means of a shackle or clevis. An unstable condition can exist if a load exceeds the machine load rating or, if a heavy load is swung over an end or side. Picking up a load over a corner is the most stable position. For the best stability, carry a load close to the machine and close to the ground. Lift capacity decreases as the distance from the swing centerline is increased.Clamshell Operation
Digging
The clamshell can swing in all directions. Personal injury can result if it swings into the cab, or a person in the work area.
When traveling, use the clamshell restraint bracket on the front of the machine, if equipped.When moving over a rough surface, keep the stick out to prevent the clamshell from swinging into the cab.Use hydraulic controls smoothly to avoid excessive clamshell swing.
1. Lower the clamshell bucket into the excavation with the stick in a vertical position. 2. For best penetration, apply down pressure as the bucket is closed.3. Raise the boom when the bucket is fully closed. 4. When the bucket clears the excavation, engage the swing control. Operate the control smoothly to avoid excessive clamshell swing. 5. Begin opening the bucket slowly when approaching the dump area. Stop the swing or stick motion slowly and open the bucket fully.6. An experienced operator can use the swinging momentum of the load to cast material for a faster cycle, and to move material farther away from the excavation.Attachment Changing
Versa-Link (If Equipped)
Place the stick near vertical. Rotate tool so that links and wedges are near vertical. Lower the attachment close to the ground but not touching the ground.The attachment should be in this position when performing the following procedure. 1. Loosen the four bolts (1) approximately 2 or 3 turns. The bolts hold the sliding wedge locks (2) in place.2. Remove the retainer bolts (3).3. Retract the sliding wedge locks (2) and reinstall the retainer bolts.4. Move the machine to the new work tool and engage the new attachment. 5. Remove the retainer bolts and move the sliding wedges down.6. Tighten the four bolts (1) and reinstall the retainer bolts (3).Hydraulic Hammer
