(1) Winch control lever. (2) FREESPOOL position. (3) Winch BRAKE OFF position. (4) Winch BRAKE ON position. (5) REEL IN position.When control lever (1) is in the BRAKE ON position (3) , the spring-applied brake that is splined to the clutch shaft firmly holds the entire gear train and the load on the winch. The bevel pinion, the bevel gear, and the reel in clutch friction discs are turning freely on the roller bearings.Moving the control lever (1) to the REEL IN position (5) shifts the spool in the control valve, sending oil pressure to both the winch brake and the clutch. The brake is released and the clutch is applied. The bevel gear now rotates the clutch shaft and the gear train. This will pull the cable to the winch drum. When the control lever (1) is returned to the BRAKE ON position (4) , the clutch releases and the brake engages. This causes the gear train to stop and the load is held in place.Moving the control lever (1) to the BRAKE OFF position (3) activates the brake solenoid valve on the winch control valve. This sends control oil pressure to the winch brake in order to release the brake. The drum can be rotated at this time, but considerable force is required since the gear train is still engaged and the gear train must be backdriven by the drum.Note: Apply the parking brake before activating the winch freespool control.To activate the winch freespool, control lever (1) must first be placed in the full BRAKE OFF position (3) , then placed into the FREESPOOL position (2) . Be sure to pause in the BRAKE OFF position (3) until any load on the drum is released and the drum has come to a complete stop. Control oil pressure is sent to the freespool cylinder. When the piston moves, the drum is mechanically disengaged from the gear train. This allows the cable to be pulled off the drum by hand.Note: When the parking brake is disengaged, the brake off function will be immediately activated and the freespool mechanical clutch will be engaged.Grapple Tong Control (17)
Note: The grapple control lever is being viewed from the operator seat.

Grapple CLOSE (16A) - Push the top left switch in order to close the grapple arms (tong). The grapple arms (tong) will close until the switch is released.
Grapple OPEN (16B) - Push the bottom left switch in order to open the grapple arms (tong). The grapple arms (tong) will open until the switch is released.
Grapple AUTOMATIC (16C) - Push the switch in the front of the control in order to turn on the automatic grab function. When the switch is activated the light on the gauge cluster will illuminate. The automatic grab switch will provide the appropriate pressure on the load. The load will not slip with the appropriate pressure. Grapple Rotator Control (18)
Note: The grapple control lever is being viewed from the operator seat.
