10 MAINTENANCE 10.3 Detecting Wear and Damage It is important to inspect all stressed parts, such as slings, spreader bar and any pivot for slings for signs of cracking, fraying, deformation or deterioration. Replace any defective parts immediately and ensure that the lift is not used until repairs are made. 10.4 Cleaning the Sling and the Lift The sling should be regularly washed in water, temperature not to exceed 180°F (82°C), and a biocidal (anti-biological) solution. A soft cloth, dampened with water and a small amount of mild detergent, is all that is needed to clean the patient lift. The lift can be cleaned with non-abrasive cleaners. 10.5 Maintaining the Manual/Hydraulic Pump  For this procedure, refer to FIGURE 10.2 on page 45. All parts of the Manual/Hydraulic Pump are precision machined, then carefully assembled and tested to ensure reliable service. The pump assembly is completely enclosed and sealed with neoprene rings to prevent leakage of hydraulic oil. A small amount of oil (about a drop) will accumulate around the piston from time to time and should be removed with a facial tissue. ƽ WARNING The pump is sealed at the factory. DO NOT attempt to open the pump or obtain local service as this will void the warranty and might result in damage and costly repair. Consult your dealer or write Invacare for further information. Replacing a Manual/Hydraulic Pump 1. Loosen the nut that secures the ball of the pump into the mounting socket. 2. Rest the boom on your shoulder and remove the nut, bolt, plastic bushing and pinch guard from the boom mounting bracket. 3. Remove the pump assembly. 4. Reverse steps for installation. ƽ CAUTION DO NOT overtighten the nut and bolt. This damages the mounting bracket. Manual/Electric Portable Patient Lift 44 Part No. 1078987
