A variable displacement bent axis motor drives the output shaft of the saw. Saw motor (10) is mounted to an adapter plate and coupled to the drive shaft by a splined coupler. Hydraulic oil for the saw motor is supplied by a pump that is mounted on the machine. The speed of the disc saw cannot be adjusted at the saw motor. Adjust the speed of the disc saw at the saw pump that is mounted on the machine.
ReferenceFor more information on adjusting the speed of the disc saw, refer to Testing and Adjusting, "Disc Saw Speed - Test and Adjust".
Disc saw (8) rotates at a constant high speed in order to fell a tree. The felling head is powered through the tree. The accumulator arms clamp the tree to the head after the cutting is complete.
ReferenceFor more information on the saw motor, refer to System Operation, "Cutoff System".
