Avoid working under any hydraulically supported devices. Hydraulically supported devices can leak,
suddenly settle or accidentally lowered. If working beneath the tractor or an implement is unavoidable, ensure to use a stand or lift apparatus with the capacity of more than 3 tons.
Prepare the Work Area Before Starting a Service Work
Make sure to clean the work area. Make sure to work in a well-ventilated area.
• engine exhaust gas contains carbon monoxide
• if inhaled, the engine exhaust gas can cause severe poisoning or even death
When working in an enclosed area, always expel the engine exhaust gas to an outdoor area.
• connect one end of an extension pipe to the engine exhaust pipe
• set the other end outside of the work area
Allow fresh outside air to flow into an enclosed work area to remove the engine exhaust gas from the area. Make sure the work area is safely and adequately illuminated.
Make sure to use light bulb enclosed in wire cage.
• Hot filament from broken light bulb can ignite spilled fuel. Use portable safety light when working inside or under the tractor.
Always keep first aid kit and fire extinguishers available in the work area.
Always keep emergency telephone numbers available in the work area such as:
• doctors
• ambulance service
• fire department
Prepare the Tools and Parts
Make sure all necessary tools are available.
• use the appropriate tools for the work
• use the correct size of tools
• makeshift tools are safety hazards Make sure to have all the parts needed.
Make sure to take time to read and understand all instructions in the Operator's Manual to familiarize with the operation and safe use of the tractor.
Make sure to keep a copy of the Operator's Manual for quick reference.
Tractor Tires and Tire Service Safety
Regularly check the tire air pressure. If the tire air pressure is low, identify the cause/s of the problem. Correct the problem before returning the tractor to service.
Always keep the tires at the correct tire air pressure level.
Avoid exceeding the recommended tire air pressure specified in the Operator's Manual.
Check the tire and rim for cuts, bubbles, damage rims and missing bolts and nuts.
Avoid mounting a tire on a rim without the proper training and the proper equipment.
Never attempt to weld or apply heat to any tractor wheel, tractor rim or tractor tire assembly.
-
welding can structurally weaken or deform the rim
-
heat can cause an increase in tire air pressure and result in an explosion
-
Never put any flammable liquid or gasses in a tractor tire.
-
Avoid standing in front of or over a tire assembly during inflation.
-
Always use a clip-on chuck and extension hose long enough for the tire to be inflated from a safe distance.
-
Always use a safety cage when working on splitrim tractor wheels.
Tractor Battery Replacement and Service Safety
• Prevent battery explosions
• before performing any service work, disconnect the negative (-) battery terminal first
• connect the positive (+) battery terminal first after the service work
• wear protective goggles and gloves
• battery can emit flammable/explosive gasses
• use extreme caution when handling batteries
• keep sparks, and open flames far away from the tractor battery
• avoid placing any metal piece across the battery posts
• Prevent acid burns
• the battery electrolyte contains sulfuric acid that is poisonous and can cause serious burns
• wear protective goggles and gloves
• fill batteries with electrolyte in a well-ventilated area
• avoid inhaling battery fumes during filling or recharging the battery
• First-aid for skin in contact with acid
• avoid getting the skin in contact with the battery electrolyte
• immediately flush with plenty of water
• immediately seek medical attention
Servicing High Pressure Tractor Hydraulic Lines & Hoses Safety
Always shut down the engine and release the pressure in the hydraulic system before disconnecting or connecting hydraulic lines.
Avoid contact with high pressure hydraulic fluids. Pressurized hydraulic fluids can:
• penetrate the skin and other body parts
• cause serious injury
When checking for leaks, run a piece of cardboard or wood block along the hydraulic lines and connections.
When high pressure hydraulic fluids accidentally penetrate the skin, immediately see a doctor.
• any fluids injected into the skin can cause gangrene and must have the proper medical attention
Do not apply heat nor weld hydraulic fluid lines using open flame.
Inspect and tighten all connections before applying pressure to the hydraulic system.
• First-aid for eyes in contact with acid
• immediately flush with running water for 15-30 minutes
• immediately seek medical attention
• First-aid once acid is swallowed
• drink large amount of milk to neutralize the acid
• immediately seek medical attention
Safety Precautions: When Servicing the Cooling System
Engines and the cooling systems are hot and pressurized during and after operations.
Allow the engine and fluids to cool down completely that can be touch with bare hands.
Avoid opening the radiator cap while the engine is hot.
Shut down the engine. Always allow the engine and the cooling system to cool down before servicing near or the cooling system.
• the radiator is hot and can cause serious burns
• the build up pressure in the cooling system can cause the coolant to spray out explosively during removal of the radiator cap that can cause serious burns
When removing the radiator cap, always:
• loosen the radiator cap to the first stop
• the preceding action releases excessive pressure on the radiator
• fully remove the radiator cap once the pressure has been released completely
Add coolant or water to the reserve tank and not to the radiator.
Safety Precautions: Servicing Rotating Blades, Augers and Power Take Off (PTO) Shafts
Avoid making contact with moving and rotating parts.
Make sure that all moving and rotating components have stopped.
Make sure to shut off the engine during:
