------ WARNING! ------

Personal injury can result from contact with refrigerant.

Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury.

Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant.

Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area.

Personal injury or death can result from inhaling refrigerant through a lit cigarette.

Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death.

Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.

Use a certified recovery and recycling cart to properly remove the refrigerant from the air conditioning system.

----------------------

    ------ WARNING! ------

    Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.

    At operating temperature, the engine coolant is hot and under pressure.

    Steam can cause personal injury.

    Check the coolant level only after the engine has been stopped and the cooling system pressure cap is cool enough to touch with your bare hand.

    Remove the cooling system pressure cap slowly to relieve pressure.

    Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.
