Winch Adjustment
The winch has an adjustable sequence valve, which permits the selection of either "no inch" or "inching" characteristics, during reel out operations.Inching is the controlled movement of the cable during a reel out operation. The "inching" setting is generally used when the machine and winch are used for construction and pipeline work. This setting gives the operator the control necessary to put an object in an exact position.Where precise control is not necessary, as when logs are moved, the "no inch" setting may be used.When using the inching setting, move the winch control lever to the reel out channel. Move the lever into the channel to start drum rotation. Use the engine speed to control the inching rate. Always use a slower engine speed for better control when inching.The adjustable sequence valve, is set on the "no inch" setting at the factory.To Adjust:
Use valve in inching position only when needed for inching out. Otherwise, possible winch damage could result.
