PIPE 7E8295 - Caterpillar

For operator comfort and longer undercarriage life, avoid traveling over stumps.Feather the controls, especially when handling a load.
To prevent blade damage, no other controls should be used when the shear blades are engaging a tree.
Shearing a Tree
1. Approach a tree with the shear frame verticle.2. If the tree is leaning to one side, tilt the frame to the same angle. Also, move the shear tip up or down to position the blades and grapple, if a tree is leaning toward or away from the machine. 3. Engage the tree just above the flare at the bottom.4. For the best stability, keep the machine as close to the tree as possible.5. Be sure the shear is fully open and firmly against the tree. 6. Close the shear and grapple completely.7. Tipping the frame back to break a tree off is not recommended. It should not be necessary if the blades are properly adjusted and the shear closes completely. 8. Use boom raise to lift the tree from the stump. The tree should lean slightly toward the machine, but not over the operator.Swinging and Bunching
1. Bring the tree close to the machine for the best stability.2. Keep the tree just high enough to clear obstacles. To prevent entangling the sheared tree in the tops of standing trees, shear the trees closest to where they will be bunched first. 3. Operate the swing control smoothly to avoid an unstable condition. 4. If traveling is necessary with a tree, feather the travel pedals to avoid sudden movements. 5. To unload a tree, tip the shear frame forward. 6. Release the shear and grapple as the tree falls, allowing the tree to drop to the ground. Gripping the tree until it hits the ground can damage the machine.Felling and Bunching Methods
The most efficient method is to operate along the face of the stand, laying the trees out into the open with the butts close together. By dropping trees in bunches, skidder production is improved, by reducing loading time. When an open space is not available, move into the stand, cutting as wide a strip as possible, laying the trees down behind the machine. Work around the outside of the stand, laying the trees to the outside.The limbers and skidders can work a safe distance behind the machine to clean up the timber before the next pass.On a steep slope, work from the bottom up to prevent an unstable condition.
Lifting capacities will vary when the machine is not level.Move the shear frame close to the machine when swinging on a hillside.
For stability on a steep slope, fell trees within a 45° sector at the front of the machine.Backhoe Operation
Digging
Know the location of buried cables. Mark them clearly before digging.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 chopping can cause structural damage. Use a digging, scratching or peeling motion when trying to
