Section 3 - Maintenance Routine Maintenance Service Requirements 3-2 3-2 9803/6580-6 Fit for Purpose Tests for Lifting Equipment T3-097 All lifting equipment (for example forks, lifting hooks and shackles) need regular inspection and testing by a competent person to ensure they are fit for purpose. This may be needed every six months or at least annually in some countries to meet and comply with legislation and for insurance purposes. Check with your local JCB distributor for further advice.

Section 3 - Maintenance Routine Maintenance Health and Safety 3-3 3-3 9803/6580-6 Health and Safety Lubricants T3-060_2 Introduction It is most important that you read and understand this information and the publications referred to. Make sure all your colleagues who are concerned with lubricants read it too. 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, so take special care when handling used oils, which might 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, plus the following. Storage Always keep lubricants out of the reach of children. Never store lubricants in open or unlabelled containers. Waste Disposal ! CAUTION It is illegal to pollute drains, sewers or the ground. Clean up all spilt fluids and/or lubricants. Used fluids and/or lubricants, filters and contaminated materials must be disposed of in accordance with local regulations. Use authorised waste disposal sites. INT-3-2-14 All waste products should be disposed of in accordance with all the relevant regulations. The collection and disposal of used oil should be in accordance with any local regulations. Never pour used engine oil into sewers, drains or on the ground. Handling ! WARNING Oil Oil is toxic. If you swallow any oil, do not induce vomiting, seek medical advice. Used engine oil contains harmful contaminants which can cause skin cancer. Do not handle used engine oil more than necessary. Always use barrier cream or wear gloves to prevent skin contact. Wash skin contaminated with oil thoroughly in warm soapy water. Do not use petrol, diesel fuel or paraffin to clean your skin. INT-3-2-3 New Oil There are no special precautions needed for the handling or use of new oil, beside the normal care and hygiene practices. Used Oil Used engine crankcase lubricants contain harmful contaminants. Here are precautions to protect your health when handling used engine oil: 1 Avoid prolonged, excessive or repeated skin contact with used oil. 2 Apply a barrier cream to the skin before handling used oil. Note the following when removing engine oil from skin: a Wash your skin thoroughly with soap and water. b Using a nail brush will help. c Use special hand cleansers to help clean dirty hands. d Never use petrol, diesel fuel, or paraffin for washing.

Section 3 - Maintenance Routine Maintenance Health and Safety 3-4 3-4 9803/6580-6 3 Avoid skin contact with oil soaked clothing. 4 Don't keep oily rags in pockets. 5 Wash dirty clothing before re-use. 6 Throw away oil-soaked shoes. First Aid - Oil Eyes In the case of eye contact, flush with water for 15 minutes. If irritation persists, get medical attention. Swallowing If oil is swallowed do not induce vomiting. Get medical advice. Skin In the case of excessive skin contact, wash with soap and water. Spillage Absorb on sand or a locally approved brand of absorbent granules. Scrape up and remove to a chemical disposal area. Fires ! WARNING Do not use water to put out an oil fire. This will only spread it because oil floats on water. Extinguish oil and lubricant fires with carbon dioxide, dry chemical or foam. Fire fighters should use self contained breathing apparatus. 7-3-1-3_1
