Machine and Axle Identification

Machine Serial Plates Each machine has a Data Plate, located to the rear left, inside the cab as shown at A. The machine serial number is inscribed at B and the engine number at C.

If the engine is replaced by a new one, the data plate serial number will be wrong. Either stamp the new number on the plate or stamp out the old one. This will prevent the wrong number being quoted when ordering replacement parts.

JS06050

JS06060

Axle Serial Plate The axle serial number is stamped on a plate mounted to the rear face of the axle, as shown. 1

When replacement parts are required, always ensure that the correct parts are obtained, e.g. in the case of gear replacements, always check the part number stamped on the gear, and the number of teeth.

When ordering replacement parts, quote the details on the serial plate as shown.

It is most important that you read and understand this information and the publications referred to. Make sure that all of your colleagues who are concerned with lubricants read it too.

First Aid - Oil

Handling

Swallowing. If oil is swallowed you should not induce vomiting. Get medical advice.

New Oil There are no special precautions needed for the handling or use of new oil, beside normal care and hygiene practices.

Skin In the case of excessive skin contact you should wash with soap and water.

Used Oil Used engine crankcase lubricants contain harmful contaminants. In laboratory tests it was shown that used engine oils can cause skin cancer.

Eyes In the case of eye contact, flush with water for 15 minutes. If irritation persists, get medical attention. Fires Extinguish with carbon dioxide, dry chemical or foam. Firefighters should use self contained breathing apparatus.

Here are precautions to protect your health when handling used engine oil: 1

Avoid prolonged, excessive or repeated skin contact with used engine oils.

Apply a barrier cream to the skin before handling used engine oil.

Note the following when removing engine oil from skin:

Hygiene JCB lubricants are not a health risk when used properly for their intended purposes. However, excessive or prolonged skin contact can remove the natural fats from your skin, causing dryness and irritation. Low viscosity oils are more likely to do this, therefore particular care is necessary in handling used oils which can be diluted with fuel contamination. Whenever you are handling oil products you should maintain good standards of care and personal and plant hygiene. For details of these precautions we advise you to read the relevant publications issued by your local health authority, and note the following:

a b c d e f g h

Wash your skin thoroughly with soap and water. Using a nail brush will help. Use special hand cleansers to help clean dirty hands. Never use petrol, diesel fuel or gas oil. Avoid skin contact with oil soaked clothing. Don't keep oily rags in pockets. Wash dirty clothing before re-use. Throw away oil-soaked shoes.

Waste Disposal All waste products should be disposed of in accordance with all the relevant regulations.

Storage Always keep lubricants out of the reach of children. Never store lubricants in open or unlabelled containers.

The collection and disposal of used engine oil should be in accordance with any local regulations. Never pour used engine oil into sewers or drains.

Spillage Absorb on sand or a locally approved brand of absorbent granules. Scrape up and remove to a chemical disposal area.

Checking the Coolant Level 1

Park the Machine on Level Ground Stop the engine and let it cool down. Open the engine compartment.

! WARNING The cooling system is pressurised when the coolant is hot. Hot coolant will burn you. Make sure that the engine is cool before checking the coolant level or draining the system. 2-3-3-3

Release System Pressure

JS04410

For location of engine cooling radiator, refer to Component Location Diagrams at the end of this section. Carefully slacken cap A. Let any pressure escape. Remove the cap. 3

Check the Level The level should be between the FULL and LOW marks on the expansion bottle B. Top up the bottle with premixed water/antifreeze if necessary. See Coolant Mixtures.

Refit the Pressure Cap A

Make sure it is tight. Note: Check the quality of the antifreeze mixture every year - before the cold weather starts. Change it every two years.

JS03930

Coolant Mixtures To prevent the coolant freezing in cold conditions, antifreeze must be added. JCB Universal Antifreeze will give protection down to the temperatures shown in the table. Antifreeze Solution

Starts to freeze at

55%

-36 Â°C (-33 Â°F)

Never use less than a 50% solution otherwise there will not be enough corrosion protection. Never use more than 60% solution otherwise the cooling system may be damaged. Leave the antifreeze in all the year round as it gives protection against corrosion. Check the strength of antifreeze solution at least once a year, preferably at the start of the cold period. Always renew the antifreeze every two years. A 50% antifreeze mixture should be used even if frost protection is not needed. This gives protection against corrosion and raises the coolant's boiling point.
