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 wheels.
Procedure
Safe working practices should be adhered to throughout.
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 gure one.
2. Remove the cover panel above the hydraulic control located on the right hand side of the
machine (held by ve 13mm headed xings). 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 gure 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 gure three. and the test point at port PS on the charge pressure connector of the driving pump, see gure four.
4. Start the engine.
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. Ret the protective covers to both test points.
7. Start the engine, activate and operate the 4WS - check the circuit for leaks – Stop the engine.
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.

Engine Oil Consumption (TB 1549)
The following instructions should be implemented for the Deutz engines tted to the Johnston CN101.
The instructions apply during the rst 500 to 700 operating hours and are intended to prevent high
oil consumption:
• Higher than usual oil consumption during the rst 500 to 700 operating hours of the running-in
period is quite normal.
• In general and especially during the running-in period the engine should not be left to idle for
long periods.
• Only use the oil grade recommended in the operator manual.
Do not use a lower grade oil. Using a lower grade oil will increase oil consumption.
• The oil level may be checked with the engine hot or cold with the engine switched off. If the
engine has been running it should be switched off for minimum of 5 minutes prior to checking the level to allow the oil to settle.
If you want to compare oil levels ensure that the oil levels to be compared are checked under
similar conditions.
• When lling, only ll up to the halfway mark on the dipstick. If you ll to the upper mark, the
engine will use the excess oil until the level drops to the halfway mark. Often this is declared as
the normal oil consumption of the engine but this is not in effect the case.
• If engine oil consumption is exceptionally high despite implementation of the running-in
instructions, you should inform your local Johnston representative. You will also be asked to record the consumption data over a period of 100 hours running time. You should record the oil
consumption and the fuel consumption for comparison.
The limit value for the maximum specic lubricant consumption is 0.75 % (max.) of fuel
consumption.
Recommended Oil Grade from Operators Manual.
Minimum Specication - ACEA E3-96/E5-02, API CH-4/CG-4, DHD-1

Health and Safety Precautions
The information presented in this section does not infer there are any particular hazards associated with these machines. It is given as a guide to the general precautions that should be taken in any workshop environment when working on machines of this nature in the course of their maintenance.
Safety symbol:
The universal symbol is used throughout this manual to indicate information which is essential for health and safety of all operating personnel.
Refer to all state, district/company, or council Health and Safety Regulations and follow the procedures laid down.
The repair and maintenance of machinery such as this can involve physical hazards or other risks to health. This section lists some of these hazards and the precautions necessary to avoid them.
The list is only general but all other operations, procedures and the handling of materials should be carried out in accordance with the requirement of health and safety laws, which is the responsibility of the Owner/Operator/Maintainer.
Anti Freeze:
Anti-freeze may be absorbed though the skin in toxic or harmful quantities. If swallowed, seek medical attention immediately. Some types, i.e., isopropanol, ethylene glycol and methanol are flammable.
Batteries:
Gases released during charging are explosive. Never use naked flames or allow sparks near charging or recently charged batteries.
Disconnection:
Disconnect the negative battery lead from battery first. The positive cable must always be disconnected last.
Reconnection:
Always reconnect the positive battery cable first.
Jump-starting and use of auxiliary (booster) batteries:
Do not jump-start maintenance free batteries if in a deeply discharged state as internal short circuits may occur.
If a maintenance free battery is found to be in a deeply discharged state, it is essential to remove the battery and recharge off the vehicle. Jump-starting will not enable the vehicles own charging system to initiate the charging process.

Jump starting procedure:
Always follow this procedure when connecting a booster battery.
Take care not to cause sparking which could ignite hydrogen gas being given off by the batteries.
1. Apply the park brake, turn off ignition, lights and other electrical loads.
2. If the slave battery is mounted on another vehicle, ensure that the vehicles are not touching.
3. Ensure that the donor battery voltage is compatible with the vehicle battery.
4. Ensure that adequate ventilation is available to the vehicle and slave batteries.
5. Connect positive terminal of the donor battery group to positive terminal of the discharged battery group.
6. Connect negative terminal or slave battery group to chassis earth of the discharged battery group.
7. Attempt to start the casualty vehicle.
8. Once the vehicle has started, remove the negative lead from the chassis and then the slave battery.
9. Remove positive lead from discharged chassis and then the donor chassis.
If the vehicle will not start with a booster battery, contact your local Johnston Service Network.
Chemical materials:
Chemical materials such as solvents, sealers, adhesive, paints, resin foams, battery acids, anti-freezes, brake fluids, oils and grease should always be used with caution and stored and handled with care.
Chemical materials may be toxic, harmful, corrosive, irritant or highly flammable and give rise to hazardous fumes and dust.
Always consult the appropriate safety standards for handling such materials.

Reminders
Chemical materials
remove chemical materials from the skin and clothing as soon as practical after soiling. Change heavily soiled clothing and have it cleaned.
carefully read and observe hazard and precaution warnings given on hazardous material containers and in any accompanying leaflets, posters or other instructions. Hazardous material health and safety data can be obtained from manufacturers.
organise work practices and use protective clothing to avoid soiling of the skin and eyes; breathing vapours, aerosols, dust, and fumes; inadequate container labelling; fire and explosive hazards.
wash before job breaks, before eating, smoking, drinking or using toilet facilities when handling chemical materials.
keep work areas clean, uncluttered and free of spills.
mix chemical materials except in accordance with the manufacturer’s instructions. Some chemicals can form other toxic or harmful substances; give off toxic or harmful fumes; be explosive when mixed together.
spray chemical materials, particularly those based on solvents, in confined spaces; for example, when people are inside a vehicle.
apply heat or flame to chemical materials, except under the manufacturer’s instructions. Some are highly flammable and some may release toxic or harmful fumes.
leave containers open. Fumes given off can build up to toxic, harmful or explosive concentrations. Some fumes are heavier than air and will accumulate in confined areas, pits, etc.
transfer chemical materials to unlabelled containers.
clean hands or clothing with chemical materials. Chemicals, particularly solvents and fuels will dry the skin and may cause irritation with dermatitis. Some can be absorbed through the skin in toxic or harmful quantities.

Dusts:
Powder, dusts or clouds may be irritant, harmful or toxic. Avoid breathing dusts from powdery chemical materials or those arising from dry abrasion operations. Wear respiratory protection in accordance with the requirement of the Health and Safety Acts.
Electric shocks:
When working on electrical systems, remove watches, bracelets and rings as these can conduct electricity and cause shorts and/or burns.
Electric shocks can result from the use of faulty electrical equipment or from the misuse of equipment even in good condition.
Ensure that electrical equipment is maintained in good condition and frequently inspected and tested.
Ensure that flexes, cables, plugs and sockets are not frayed, kinked, cut, cracked or otherwise damaged.
Ensure that electrical equipment is protected by the correct rated fuse and if used outside an earth-leakage circuit breaker is used.
Never misuse electrical equipment and never use equipment that is in any way faulty. The results could be fatal.
Use reduced voltage equipment (110 or 24 volt) for inspection and working lights where possible.
Ensure that the cables of mobile electrical equipment cannot be trapped and damaged such as in a vehicle hoist, trolley jacks, etc.
Use air operated mobile equipment where possible in preference to electrical equipment.
Exhaust fumes:
These contain asphyxiating, harmful and toxic chemicals and particles such as carbon oxides, nitrogen oxides, aldehydes, leads and aromatic hydrocarbons. Engines should only be run under conditions of adequate extraction or general ventilation and not in confined spaces.
NB : Catalyst exhausts/silencers can run at extremely high temperatures.
Fire and welding:
Observe strict fire safety when storing and handling flammable materials or solvents, particularly near electrical equipment or welding processes. Disconnect battery, microprocessors, etc. before commencing welding. Failure to observe this could cause failure of components. Ensure before using electrical or welding equipment that there is no fire hazard present. Have a suitable fire extinguisher available when using welding or heating equipment. Special precautions must be taken before any welding or cutting takes place on vessels which have contained combustible materials, e.g. fuel tanks. The sound insulation foam used on the equipment must be removed if any welding is to be carried out in that area of the machine.

CN101 - Maintenance
First aid:
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. Do not induce vomiting (unless indicated by the manufacturer).
High-pressure air and lubrication equipment:
Always keep high-pressure equipment in good condition and regularly maintained, particularly at joints and unions.
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.
Oils and greases:
Prolonged and repeated contact with mineral oil may result in the removal of natural fats from the skin, leading to dryness, irritation and dermatitis. Gross and prolonged contact, especially with used engine oil, which contains potentially harmful contaminants, may cause skin cancer.
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.
Adequate means of skin protection and washing facilities should be provided.
Repeated or prolonged skin contact should be avoided by wearing protective clothing, including impervious gloves where practical. Particular care should be taken with used oils and greases containing lead.
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.

Solvents:
Solvents such as acetone, white spirit, toluene, xylene and trichloroethane are flammable.
Avoid splashes to the skin, eyes and clothing. Wear protective gloves, goggles and clothing.
When using solvents ensure good ventilation; avoid breathing fumes, vapours, spray­mists and keep containers tightly sealed. Do not use in confined spaces. When spraying materials containing solvents, for example paints, adhesives or coatings, use extraction ventilation or personal respiratory protection in the absence of adequate general ventilation.
Do not apply heat or flame except under specific and detailed manufacturer’s instructions.
Suspended loads:
Never work under an unsupported, suspended or raised load. For example, jacked up vehicle, raised tipper body, suspended engine, etc.
Always ensure that lifting equipment e.g., jacks, hoists, axle stands, slings, etc are adequate and suitable for the job, in good condition and regularly maintained.
NEVER improvise lifting tackle. ALWAYS ensure body props and/or axle stands are used when working under bodies or chassis.
Workshop tools and equipment:
Only use tools and equipment for their intended purposes.
Never overload equipment such as hoists, jacks, axles stands or lifting slings. Damage caused by overloading is not always immediately apparent and may result in a fatal failure the next time the equipment is used.
Never use damaged or defective tools or equipment.
Always wear suitable eye protection when using grinding, chiselling or air guns.
Always wear a suitable breathing mask when using sand blasting equipment, working with asbestos based materials (such as brake linings) or using spraying equipment.
