4WS Bleeding
              The following outlines the correct procedure for the removal of air from the Johnston CN101 rear
              hydraulic 4 wheel steering (4WS) cylinder.
              Should for any reason air be introduced into the 4WS hydraulic system (hose replacement, etc.)
              the following procedure must be undertaken to ensure that the 4WS system functions safely and
              as intended.
Air in the rear steering cylinder may result in inconsistent control and poor centralisation of the rear
                                                                                                                            All Copyright and rights are the property of Johnston Sweepers Ltd.
              wheels.
Procedure
              1.	 Start the engine, raise the hopper and support on the prop. Activate the 4WS and turn the
                  steering wheel fully to the left hand lock (rear wheels will point to the right hand side). Stop the
                  engine; the rear steering cylinder is now at its maximum stroke, see figure one.
              2. Remove the cover panel above the hydraulic control located on the right hand side of the
                 machine (held by five 13mm headed fixings). Fit the tee piece and test point between the hose
                 and adaptor at the HB port on the 4WS hydraulic valve block and tighten securely with the test
                 point facing vertically, see figure two.
              3. From the hydraulic test kit use one of the test hoses to connect between the test point at HB
                 on the 4WS hydraulic valve block, see figure three. and the test point at port PS on the charge
                 pressure connector of the driving pump, see figure four.
                                                            Warning
                Starting the engine will charge the 4WS hydraulic valve block output HB to a pressure of
                   25 bar. Any air trapped within the system will also be compressed to this pressure.
Suitable precautions must be applied when venting the circuit in the following steps.
              5. Whilst taking all necessary precautions to protect the any personnel and the surrounding area
                 from any air and oil that is released. Slowly undo the banjo connector bolt on the rear steering
                 cylinder until any trapped air and oil is seen to be released from the connection. Repeat several
                 times or until no air is seen to be expelled and then retighten the connection bolt ensuring
                 correct orientation of the hose.
              6. Stop the engine; disconnect the test hose from the 4WS hydraulic valve block and the charge
                 pressure connector of the driving pump. Refit the protective covers to both test points.
7. Start the engine, activate and operate the 4WS - check the circuit for leaks – Stop the engine.
                                                                              8. Refit the cover panel over the hydraulic controls and top up the hydraulic oil as required – see
                                                                                 operator’s gu for further details.

                                    It is desirable for someone in the workshop to be trained in the first aid procedures.
                                    Splashes or particles in the eye should be flushed with clean water for at least ten minutes
                                    and medical attention sought.
                                    Soiled skin should be washed with soap and water.
                                    Inhalation affected individuals should be removed to fresh air immediately.
                                    If hazardous material has been swallowed or if the effects of exposure to hazardous
                                    materials persist, consult a doctor with information (label) on material used.

                                    Never direct a high (or low) pressure nozzle at the skin as the fluid may penetrate to the
                                    underlying tissue, etc, and cause serious and potentially fatal injury.
                                    Where there is a risk of eye contact, e.g., by splashing, eye protection should be worn,
                                    for example, chemical goggles or face shields; in addition, an eyewash facility should be
                                    provided.
First Aid treatment should be obtained immediately for open cuts and wounds.
Apply barrier cream before each work period to help when removing oil from the skin.
Use proprietary hand cleaners only if they can be removed from the skin using water.
                                    Overalls must be cleaned regularly. Discard clothing that cannot be cleaned and footwear
                                    that has become impregnated.
                                    In the event of a skin condition occurring consult a doctor and tell him/her that your work
                                    involves using oil.
