Do not weld on pipes or on tubes that contain flammable

Burn Prevention
When checking the radiator coolant level, shut down 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.
