Practice Safe Maintenance
TS218-UN: Keep Area Clean
Understand service procedure before doing work. Keep area clean and dry. Never lubricate, service, or adjust machine while it is moving. Keep hands, feet, and clothing away from power-driven parts. Disengage all power and operate controls to relieve pressure. Lower equipment to the ground. Stop the engine. Remove the key. Allow machine to cool. Securely support any machine elements that must be raised for service work. Keep all parts in good condition and properly installed. Fix damage immediately. Replace worn or broken parts. Remove any buildup of grease, oil, or debris. On self-propelled equipment, disconnect battery ground cable () before making adjustments on electrical systems or welding on machine. On towed implements, disconnect wiring harnesses from tractor before servicing electrical system components or welding on machine. Falling while cleaning or working at height can cause serious injury. Use a ladder or platform to easily reach each location. Use sturdy and secure footholds and handholds. DX,SERV-19-20170228
Use Proper Tools
TS779-UN: Proper Tools
Use tools appropriate to the work. Makeshift tools and procedures can create safety hazards. Use power tools only to loosen threaded parts and fasteners.

Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, eat holes in clothing, and cause blindness if splashed into eyes. Avoid the hazard by:
Filling batteries in a well-ventilated area. Wearing eye protection and rubber gloves. Avoiding breathing fumes when electrolyte is added. Avoiding spilling or dripping electrolyte. Use proper jump start procedure. If you spill acid on yourself:
Flush your skin with water. Apply baking soda or lime to help neutralize the acid. Flush your eyes with water for 15—30 minutes. Get medical attention immediately. If acid is swallowed:
Do not induce vomiting. Drink large amounts of water or milk, but do not exceed 2 L (2 quarts). Get medical attention immediately. DX,POISON-19-19930421
Prevent Battery Explosions
TS204-UN: Battery Explosions
Keep sparks, lighted matches, and open flame away from the top of battery. Battery gas can explode. Never check battery charge by placing a metal object across the posts. Use a volt-meter or hydrometer. Do not charge a frozen battery; it may explode. Warm battery to 16°C (60°F). DX,SPARKS-19-19930303
