Maintenance Safety (cont'd) ! WARNING Hydraulic Hoses Damaged hoses can cause fatal accidents. Inspect the hoses regularly for: - Damaged end fittings - Chafed outer covers - Ballooned outer covers - Kinked or crushed hoses - Embedded armouring in outer covers - Displaced end fittings. INT-3-3-2 ! WARNING Waxoyl contains turpentine substitute, which is flammable. Keep flames away when applying Waxoyl. Waxoyl can take a few weeks to dry completely. Keep flames away during the drying period. Do not weld near the affected area during the drying period. Take the same precautions as for oil to keep Waxoyl off your skin. Do not breathe the fumes. Apply in a well-ventilated area. 5-3-1- 9 !
WARNING To avoid burning, wear protective gloves when handling hot components. To protect your eyes, wear goggles when using a wire brush to clean components. HYD 1-3 ! WARNING Fluoroelastomeric Materials Certain seals and gaskets (e.g. crankshaft oil seal) on JCB machines contain fluoroelastomeric materials such as Viton, Fluorel and Technoflon. Fluoroelastomeric materials subjected to high temperatures can produce highly corrosive hydrofluoric acid. THIS ACID CAN SEVERELY BURN. ! WARNING A raised and badly supported machine can fall on you. Position the machine on a firm, level surface before raising one end. Ensure the other end is securely chocked.
Do not rely solely on the machine hydraulics or jacks to support the machine when working under it. New fluoroelastomeric components at ambient temperature require no special safety precautions. Used fluoroelastomeric components whose temperatures have not exceeded 300°C require no special safety precautions. If evidence of decomposition (e.g. charring) is found, refer to the next paragraph for safety instructions. DO NOT TOUCH COMPONENT OR SURROUNDING AREA. Disconnect the battery, to prevent the engine being started while you are beneath the machine. GEN-1-1 Used fluoroelastomeric components subjected to temperatures greater than 300°C (e.g.
engine fire) must be treated using the following safety procedure. Make sure that heavy duty gloves and special safety glasses are worn: ! WARNING Make the machine safe before working underneath it. Park the machine on level ground, lower the arms. Apply the parking brake, put the transmission in neutral and stop the engine. Chock both sides of all four wheels. 1 Ensure that components have cooled then remove and place material into plastic bags. Disconnect the battery, to prevent the engine being started while you are beneath the machine.
GEN-1-2 2 Thoroughly wash contaminated area with 10% calcium hydroxide or other suitable alkali solution, if necessary use wire wool to remove burnt remains. ! WARNING JCB Extradig Dipper Lubricant JCB Extradig dipper lubricant contains 1.53% lead. The repeated swallowing of very small quantities can cause chronic lead poisoning. Do not smoke or touch food while handling this lubricant. Dispose of waste (rags etc.) in accordance with local regulations. 2-1-1-8 3 Thoroughly wash contaminated area with detergent and water. 4 Contain all removed material, gloves etc. used in this operation in sealed plastic bags and dispose of in accordance with Local Authority Regulations.
DO NOT BURN FLUOROELASTOMERIC MATERIALS. If contamination of skin or eyes occurs, wash affected area with a continuous supply of clean water or with calcium hydroxide solution for 15-60 minutes. Get medical attention immediately. INT-3-3-5/1 9803/7110 Issue 1 Section 2 Care & Safety Section 2 4 - 3 4 - 3
