1. Tube or hose 2.
1. Ensure that all the threads, the sealing surfaces of the hose/tube, and the
fitting are free of burrs, nicks, scratches, or unwanted material.
2. Align the hose/tube against the body of the fitting so that the face of the
hose/tube sleeve fully touches the face of the fitting.
Note: It may be necessary to use a drive-adapter wrench (e.g., crowfoot
wrench) to install a hydraulic fitting; refer to

3. Use your hand to thread the swivel nut onto the fitting. While you hold the
hose/tube in alignment with a wrench, use a torque wrench to tighten the
swivel nut to the recommended torque value within the specified range of
torque values; refer to the
The hydraulic hoses used on the GreensPro 1240 machines have
BSPP (British Standard Parallel Pipe) threads. The hydraulic hoses
used on the GreensPro 1260 machines have ORFS (O-Ring Face
Seal) threads. If hoses are replaced, ensure that the replacement
has the correct type of threads, or component damage and leakage
will occur.
