SAFETY If a maintenance procedure must be performed with the engine running, do not leave machine unattended. If the machine must be raised, maintain a 90 to 100° angle between the boom and arm. Securely support any machine elements that must be raised for service work. Inspect certain parts periodically and repair or re- place as necessary. Refer to the section discuss- ing that part in the "MAINTENANCE" chapter of this manual. Keep all parts in good condition and properly in- stalled. Fix damage immediately. Replace worn or broken parts. Remove any buildup of grease, oil, or de- bris. When cleaning parts, always use nonflammable detergent oil.
Never use highly flammable oil such as fuel oil and gasoline to clean parts or surfaces. Disconnect battery ground cable (-) before mak- ing adjustments to electrical systems or before performing welding on the machine. Sufficiently illuminate the work site. Use a main- tenance work light when working under or inside the machine. Always use a work light protected with a guard. In case the light bulb is broken, spilled fuel, oil, anti- freeze fluid, or window washer fluid may catch fire.
