BURN PREVENTION
When checking the radiator coolant level, stop the engine, let the engine and radiator cool down, then
check the coolant recovery tank. If the coolant level in the coolant recovery tank is near the upper limit,
there is enough coolant in the radiator.
Loosen the radiator cap gradually to release the internal pressure before removing the radiator cap.
If the coolant level in the coolant recovery tank is below the lower limit, add coolant.
Cooling system conditioner contains alkali. Alkali can cause personal injury. Do not allow alkali to contact
the skin, the eyes, or the mouth.
Allow cooling system components to cool before you drain the cooling system.
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact
the skin.
Remove the hydraulic tank filter plug only after the engine has been stopped. Make sure that the hydraulic
tank filter plug is cool before you remove it with your bare hand. Remove the hydraulic tank filter plug
slowly to relieve pressure.
Relieve all pressure in the hydraulic oil system, in the fuel system, or in the cooling system before you
disconnect any lines, fittings, or related items.
Batteries give off flammable fumes that can explode.
Do not smoke while you are checking the battery electrolyte levels.
Electrolyte is an acid. Electrolyte can cause personal injury. Do not allow electrolyte to contact the skin or
the eyes.
Always wear protective glasses when you work on batteries.
