Battery gas can explode. · Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer. · Do not charge a frozen battery; it may explode. Warm battery to 16°C (60°F). Prevent Acid Burns · 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 acid burns by: 1. Filling batteries in a well-ventilated area. 2. Wearing eye protection and rubber gloves. 3. Avoiding breathing fumes when electrolyte is added. 4. Avoiding spilling or dripping electrolyte. 5. Using proper jump start procedure. Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid injury from escaping fluid under pressure by stopping the engine and relieving pressure in the system before disconnecting or connecting hydraulic or other lines. Tighten all connections before applying pressure. Search for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids. If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A. Avoid Heating Near Pressurized Fluid Lines · If you spill acid on yourself: 1. Flush your skin with water. 2. Apply baking soda or lime to help neutralize the acid. 3. Flush your eyes with water for 10--15 minutes. 4. Get medical attention immediately. · If acid is swallowed: 1. Drink large amounts of water or milk. 2. Then drink milk of magnesia, beaten eggs, or vegetable oil. 3. Get medical attention immediately. Flammable spray can be generated by heating near pressurized fluid lines, resulting in severe burns to yourself and bystanders. Do not heat by welding, soldering, or using a torch near pressurized fluid lines or other flammable materials. Pressurized lines can be accidentally cut when heat goes beyond the immediate flame area. 6/29/99 1 - 3 SAFETY USE SAFE SERVICE PROCEDURES Wear Protective Clothing Park Machine Safely Wear close fitting clothing and safety equipment appropriate to the job. Prolonged exposure to loud noise can cause impairment or loss of hearing. Wear a suitable hearing protective device such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises. Operating equipment safely requires the full attention of the operator. Do not wear radio or music headphones while operating machine. Service Machines Safely Before working on the machine: 1. Lower all equipment to the ground. 2. Stop the engine and remove the key. 3. Disconnect the battery ground strap. 4. Hang a "DO NOT OPERATE" tag in operator station. Support Machine Properly and Use Proper Lifting Equipment Tie long hair behind your head. Do not wear a necktie, scarf, loose clothing, or necklace when you work near machine tools or moving parts. If these items were to get caught, severe injury could result. Remove rings and other jewelry to prevent electrical shorts and entanglement in moving parts. Use 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. For loosening and tightening hardware, use the correct size tools. DO NOT use U.S. measurement tools on metric fasteners. Avoid bodily injury caused by slipping wrenches. Use only service parts meeting John Deere specifications. If you must work on a lifted machine or attachment, securely support the machine or attachment. Do not support the machine on cinder blocks, hollow tiles, or props that may crumble under continuous load. Do not work under a machine that is supported solely by a jack. Follow recommended procedures in this manual. Lifting heavy components incorrectly can cause severe injury or machine damage. Follow recommended procedure for removal and installation of components in the manual. Work in Clean Area Before starting a job: 1. Clean work area and machine. 2. Make sure you have all necessary tools to do your job. 3. Have the right parts on hand. 4. Read all instructions thoroughly; do not attempt shortcuts. 1 - 4 6/29/99 SAFETY Using High--Pressure Washers Directing pressurized water at electronic/electrical components or connectors, bearings, hydraulic seals, fuel injection pumps or other sensitive parts and components may cause product malfunctions. Reduce pressure and spray at a 45 to 90 degree angle. Illuminate Work Area Safely Illuminate your work area adequately but safely. Use a portable safety light for working inside or under the machine. Make sure the bulb is enclosed by a wire cage. The hot filament of an accidentally broken bulb can ignite spilled fuel or oil. Work in Ventilated Area Avoid Harmful Asbestos Dust Avoid breathing dust that may be generated when handling components containing asbestos fibers. Inhaled asbestos fibers may cause lung cancer. Components in products that may contain asbestos fibers are brake pads, brake band and lining assemblies, clutch plates, and some gaskets. The asbestos used in these components is usually found in a resin or sealed in some way. Normal handling is not hazardous as long as airborne dust containing asbestos is not generated. Avoid creating dust. Never use compressed air for cleaning. Avoid brushing or grinding material containing asbestos. When servicing, wear an approved respirator. A special vacuum cleaner is recommended to clean asbestos. If not available, apply a mist of oil or water on the material containing asbestos. Keep bystanders away from the area. SERVICE TIRES SAFELY Engine exhaust fumes can cause sickness or death. If it is necessary to run an engine in an enclosed area, remove the exhaust fumes from the area with an exhaust pipe extension. If you do not have an exhaust pipe extension, open the doors and get outside air into the area. WARNING: California Proposition 65 Warning Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm. Gasoline engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. Remove Paint Before Welding or Heating Avoid potentially toxic fumes and dust. Hazardous fumes can be generated when paint is heated by welding, soldering, or using a torch. Do all work outside or in a well ventilated area. Dispose of paint and solvent properly. Remove paint before welding or heating. If you sand or grind paint, avoid breathing the dust. Wear an approved respirator. If you use solvent or paint stripper, remove stripper with soap and water before welding. Remove solvent or paint stripper containers and other flammable material from area. Allow fumes to disperse at least 15 minutes before welding or heating. Explosive separation of a tire and rim parts can cause serious injury or death. Do not attempt to mount a tire unless you have the proper equipment and experience to perform the job. Always maintain the correct tire pressure. Do not inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion. Welding can structurally weaken or deform the wheel. When inflating tires, use a clip-on chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. Use a safety cage if available. Check wheels for low pressure, cuts, bubbles, damaged rims or missing lug bolts and nuts. 6/29/99 1 - 5 SAFETY AVOID INJURY FROM ROTATING BLADES, AUGERS AND PTO SHAFTS HANDLE CHEMICAL PRODUCTS SAFELY Keep hands and feet away while machine is running. Shut off power to service, lubricate, or remove mower blades, augers, or PTO shafts. SERVICE COOLING SYSTEM SAFELY Explosive release of fluids from pressurized cooling system can cause serious burns. Shut off machine. Remove filler cap only when cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely. Direct exposure to hazardous chemicals can cause serious injury. Potentially hazardous chemicals used with John Deere equipment include such items as lubricants, coolants, paints, and adhesives. A Material Safety Data Sheet (MSDS) provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques. Check the MSDS before you start any job using a hazardous chemical. That way you will know exactly what the risks are and how to do the job safely. Then follow procedures and recommended equipment. Dispose of Waste Properly Improperly disposing of waste can threaten the environment and ecology. Potentially harmful waste used with John Deere equipment includes such items as oil, fuel, coolant, brake fluid, filters, and batteries. Use leakproof containers when draining fluids. Do not use food or beverage containers that may mislead someone into drinking from them. Do not pour waste onto the ground, down a drain, or into any water source. Inquire on the proper way to recycle or dispose of waste from your local environmental or recycling center, or from your John Deere dealer.

SPECIFICATIONS AND INFORMATION Sealing Surface Special Nut Special Washer Angle Fitting O-ring Sealing Surface 1. Inspect the fitting sealing surfaces. They must be free of dirt or defects. 2. Inspect the O-ring. It must be free of damage or defects. 3. Lubricate O-rings and install into groove using petroleum jelly to hold in place. 4. Push O-ring into the groove with plenty of petroleum jelly so O-ring is not displaced during assembly. 5. Index angle fittings and tighten by hand pressing joint together to insure O-ring remains in place. 6. Tighten fitting or nut to torque value shown on the chart per dash size stamped on the fitting. Do not allow hoses to twist when tightening fittings. O-RING BOSS FITTINGS 1. Inspect boss O-ring boss seat. It must be free of dirt and defects. If repeated leaks occur, inspect for defects with a magnifying glass. Some raised defects can be removed with a slip stone. Groove O-ring 2. Put hydraulic oil or petroleum jelly on the O-ring. Place electrical tape over the threads to protect Oring from nicks. Slide O-ring over the tape and into the groove of fitting. Remove tape. 3. For angle fittings, loosen special nut and push special washer against threads so O-ring can be installed into the groove of fitting. 4. Turn fitting into the boss by hand until special washer or washer face (straight fitting) contacts boss face and O-ring is squeezed into its seat. 5. To position angle fittings, turn the fitting counterclockwise a maximum of one turn. 6. Tighten straight fittings to torque value shown on chart. For angle fittings, tighten the special nut to value shown in the chart while holding body of fitting with a wrench.
