Operating Backhoe Hydraulic Thumb (If Equipped)

IMPORTANT: Improper use of hydraulic thumb damages the backhoe and/or thumb.

Do not use the hydraulic thumb:

• As a pry bar to loosen objects.
• To push or pull material or objects.
• To move objects from side to side.
• As an area to wrap a chain or rope for lifting purposes.

NOTE: Grasping large objects such as rocks and logs increases momentum of the backhoe as it moves from side to side.

Do not make sudden start and stops when moving large objects.

Be aware when lifting and moving long objects that extend beyond normal backhoe swing area.

Be aware when clearing brush because the object being uprooted can fall towards the operator.

Bucket Lever Label—With Backhoe Thumb

A - Knob

• The bucket cylinder and hydraulic cylinder are now linked together into one circuit and controlled by the bucket lever.
• When clamping on an object with the thumb, it is normal that the bucket or thumb moves separately of each other until one of them contacts the object.
• Upon contact, the bucket/thumb stops and the opposite bucket/thumb moves and clamps onto the object.
• It is normal that the bucket and backhoe thumb do not move at the same rate of speed during operation.

Place the backhoe thumb in the storage position when it is not in use.

• Activate the hydraulic thumb by pulling out the knob on the thumb valve.
• Curl out the bucket and hold until both bucket and backhoe thumb cylinders are fully retracted.
• Push the knob on the backhoe thumb valve down. Thumb cylinder is now out of the circuit and the bucket operates as normal.
