OPERATING INSTRUCTIONS
USING THE WORK FUNCTIONS
The following pages explain the operation of the Work functions Swing, Crowd, Tool, Leveler and Hoist/Utility. Use "feathering" technique to vary work speed and maintain functional controL
Avoid jerky and abrupt control engagement. Such a method of operation may look flashy, but is inefficient and hard on machine components. Do not use Throttle as substitute for "feathering" technique.
Before attempting to cut trees, study the individual work functions carefully. Practice to develop coordination so that you can lower the Hoist, Crowd out, and actuate the Tool Cylinder to keep the Feller/Buncher vertical. Then reverse this sequence, Swinging and opening the Shear Arms at the same time. Perform these functions at no more than half throttle at first. Gradually increase the speed. As the sequences become mastered you will sOon be ready to cut trees at full speed.
The function of the Swing and Crowd controls can be interchanged on the LOGGER. Before working the machine, check the use of each control in a safe area. If the Swing and Crowd controls are interchanged, a new OPERATOR'S CONTROL DECAL must be installed in the cab at the time of the change. See page 40 for the correct procedure for interchanging the controls.
24
USING THE LEVELER CONTROL
The Turntable can be tilted up to 8-1/2° to help level the Feller/Buncher.
Standard gauge units are equipped with two Leveler Cylinders; Wide gauge units have four. NOTE: On earlier units, leveler locks are installed on the leveler base. When shipping the machine, these Locks should be placed under the
leveler ears. Before operating the machine, make sure the Locks are swung out from under the ears and held securely in place by their springs. On units without leveler IOGks, use a block of wood, under the leveler ears to keep the upperstructure level during transport. .
To tilt the Turntableto the right (Item 1, Figure 12), push the Control Handle forward. ,. .
To tilt the Turntable to the left, (Item 2, Figure 12), pull the Control Handle back.

OPERATING INSTRUCTIONS
USING THE SWING CONTROL
AWARNING: Before swinging, . check area around the machine for people or objects wlthm range of the Feller/Buncher or the cut tree as it is dropped.
Always start and stop Turntable rotation with a smooth, feathering motion of the control. The House Brake Control Handle should be used as a holding brake only. Never use it to stop Turntable rotation, except in an emergency.
L"i.. WARNING : CROWD INTERCHANGEABLE. AND SWING THEREFORE CONTROLS THE OPER. .\RE \ TOR .. (REGARDLESS OF EXPERIENCE) :\ll'ST CHECK CONTROLS PRIOR TO OPERATION.
Figure 13. Swing Right/Left Operation
To swing left (Item 2, Figure 13), press the Swing Pedal down with the heel.
The amount of control movement will determine the rate of swing (up to 6 rpm). To stop the swing,smoothly return the control to NEUTRAL.
To swing right (Item 1, Figure 13), press the Swing Pedal down with the toe. Stop the swing in the same manner as for swinging left.

OPERATING THE FELLER-BUNCHER
NOTE: Before attempting to cut trees, study USING THE WORK FUNCTIONS carefully. Then practice coordinated use of work functions as described on Page 24.
Kno\\ you r Feller! Bun cher capac it ies. Refer to SPECIFICATIONS. page 11, for maximum tree diameter and weights. The Feller!Buncher is designed to handle a maximum sized tree at IT radius.
NOTE: Always ensure that Cab Guards are in place during operation.
Planning the Job
Before starting work, study the ground conditions, terrain and type of timber stand to be cut. Then plan your work based on the conditions found. The following rules apply:
1. For maximum efficiency, keep swing arc as short as possible, preferably within 900 , depending on the work situation.
2. Cut (or knock down) dead trees and stubs to prevent accidents.
WARNING: HANDLE DEAD TREES WITH EXTREME CARE. Keep them leaning forward to keep tops from falling onto the machine. Bumping dead trees from the side will normally make the tops fall sideways, away from the machine.
3. It is best to work along the face of timber stand, laying the trees in a
herringbone pattern out into the open with the butts close together and the tops fanned out as shown in Figure 18. This will allow room for limbing and toppinI!'. The width of cut (up to 52') is governed by the room you have to lay the trees down.
29
OPERATING INSTRUCTIONS
Figure 18. Working Along the Face of a Timber Stand
4. The machine can work in a large circle or around a square with the limbers and skidders at a safe distance behind it. They will clean out the fallen timber to keep it from getting covered up on the next pass.
5. When starting into the center of a block of timber, cut as wide a strip as possible. Lay the trees down behind the machine in a herringbone pattern to prevent covering up any trees. The machine may have to
come back without cutting to start the next strip, after the first trees are cleaned up. (Refer to Figure 19).
30
Figure 19. Working through Center of Block of Timber
Cutting the Tree
Place the Feller/Buncher in a vertical position for cutting. The Shear pocket should engage the tree fully. The Grab Arms have a large range and their placement is not too critical. Position the Feller/Buncher so that the Shear Arms make contact with the tree bElfore the Grab Arms. When cut, this will permit the tree to fall back into the proper position for swinging.
IMPORTANT: Do not use any of the machine controls while the tree is being cut. Pressure exerted against the FeIler/Buncher while the tree is being cut can cause the cutter blades to bend or break.
Cut the tree as follows:
2. Move as close to the tree as possible.
31
OPERATING INSTRUCTIONS
CUTTING THE TREE (CON'T.)
3. Place the shear firmly against the tree. Then close the shear arms. The knives should cut through the entire tree. If they do not, blade adjustment may be necessary. NOTE: "Racking" of Feller/Buncher to break tree off at stump is not With proper shear knife adjustment, the tree will be cut off
completely.
Figure 20. Proper Position for Cutting
Unloading and Piling the Tree
Mter the tree is cut use the following procedure:
1. Use the Crowd, Hoist and Tool functions to bring the tree in close to the machine. The tree should be in a vertical position, leaning slightly
toward but not over the Cab. See Figure 21.
2. Swing the tree into position for unloading. Tilt the head forward to start the tree falling. Release the tree BEFORE it hits the ground. This is easier on the machine and Operator, increases productivity, and smashes the branches to allow stacking more trees in a pile. (Refer to
Figure 22).
32
Figure 21. Tree Position After Cutting
3. Avoid entangling sheared trees in the tops of standing trees. This can be prevented by shearing trees closest to where they will be bunched.
4. Lay the first trees that are cut close to the machine at a 90° angle, or
off to one side. This will put more trees in one place for increased skidder production.
5. Try to lay tree butts on a windfall or knoll to help the choker setter pick up the bunch.
