7 SETUP/MAINTENANCE 7.4 Batteries ƽ WARNING Invacare strongly recommends that battery installation and battery replacement always be done by a qualified technician. The use of rubber gloves is recommended when working with batteries. After ANY adjustments, repair or service and before use, make sure all attaching hardware is tightened securely otherwise injury or damage may result. 22NF batteries weigh 49 pounds each. GP24 batteries weigh 51 pounds each.Use proper lifting techniques (lift with your legs) to avoid injury. ALWAYS use a battery lifting strap when lifting a battery. It is the most convenient method and assures that the battery acid will not spill. DO NOT tip the batteries. Keep the batteries in an upright position. NEVER allow any of your tools and/or battery cable(s) to contact BOTH battery post(s) at the same time. An electrical short may occur and serious personal injury or damage may occur. When tightening the clamps, always use a box wrench. Pliers will "round off" the nuts. NEVER wiggle the battery terminal(s)/post(s) when tightening. The battery may become damaged. The POSITIVE (+) RED battery cable MUST connect to the POSITIVE (+) battery terminal(s)/post(s), otherwise serious damage will occur to the electrical system. Install protective caps on POSITIVE (+) and NEGATIVE (-) battery terminals. Do not remove fuse or mounting hardware from POSITIVE (+) red battery cable mounting screw. Unless otherwise indicated, make sure power to the wheelchair is OFF before performing these procedures. After ANY adjustments, repair or service and before use, make sure all attaching hardware is tightened securely otherwise injury or damage may occur. Invacare® TDX®SP, TDX SR 80 Part No 1143190
