General Safety Instructions
WARNING
Improper practices, carelessness, or ignoring any warnings may cause property damage, personal injury, or death.
WARNING
Manually rotating the crankshaft requires a trained technician and specialty tools. DO NOT pull or pry on the fan in an
attempt to rotate the crankshaft. Applying force to the fan can damage the fan blades or cause premature fan failure.
Failure to comply with the approved procedure may result in property damage, personal injury, or death.
Before performing any repair, read and understand all of the safety precautions and warnings. The following is a list of
general safety precautions that must be followed to provide personal safety. Failure to follow these instructions may cause
death or injury. Special safety precautions are included in the procedures when they apply.
Keep in mind that even a well maintained vehicle must be operated within the range of its mechanical capabilities and the
limits of its load ratings. See the Weight Ratings label on the driver's door edge.
Every new vehicle is designed to conform to all Federal Motor Vehicle Safety Standards applicable at the time of
manufacture. Even with these safety features, continued safe and reliable operation depends greatly upon regular vehicle
maintenance. Follow the maintenance recommendations found in the Preventive Maintenance section. This will help
preserve your investment.
Make sure your vehicle is in top working condition before heading out on the road, it is the responsible driver's duty to do
so. Inspect the vehicle according to the Driver's Check List.
•
Work areas should be dry, well lit, well ventilated, free from clutter, loose tools, parts, ignition sources and
hazardous substances.
•
Wear protective glasses and protective shoes when working.
•
DO NOT wear loose-fitting or torn clothing. Tie back and/or tuck in long hair. Remove all jewelry when working.
•
Before beginning any repair, disconnect the battery (negative [-] cable) and discharge any capacitors.
•
Put a “DO NOT OPERATE” tag in the operator's compartment or on the controls.
•
Allow the engine to cool before slowly loosening the coolant fill cap to relieve the pressure from the cooling system.
WARNING
Removing the fill cap on a hot engine can cause scalding coolant to spray out and burn you badly. If the engine has been in opera-
tion within the previous 30 minutes, be very careful in removing the fill cap. Protect face, hands, and arms against escaping fluid and
steam by covering the cap with a large, thick rag. DO NOT try to remove it until the surge tank cools down or if you see any steam or
coolant escaping. Always remove the cap very slowly and carefully. Be ready to back off if any steam or coolant begins to escape.
Failure to comply may result in death, personal injury, equipment or property damage.
•
Always use wheel chocks or proper jack stands to support the vehicle or vehicle components before performing
any service work. DO NOT work on anything that is supported only by lifting jacks or a hoist. Before resting a
vehicle on jack stands, be sure the stands are rated for the load you will be placing on them.
•
Before removing or disconnecting any lines, fittings, or related items, relieve all pressure in the air, oil, fuel, and
cooling systems. Remain alert for possible pressure when disconnecting any device from a system that contains
pressure. High pressure oil or fuel can cause death or personal injury.
•
Always wear protective clothing when working on any refrigerant lines and make sure that the workplace is well
ventilated. Inhalation of fumes can cause death or personal injury. To protect the environment, liquid refrigerant
systems must be properly emptied and filled using equipment that prevents the release of refrigerant gas. Federal
law requires capturing and recycling refrigerant.
•
When moving or lifting any heavy equipment or parts, make sure to use proper techniques and assistance. Ensure
all lifting devices such as chains, hooks, or slings are in good condition and are of the correct load capacity. Make
sure all lifting devices are positioned correctly.
•
Corrosion inhibitors and lubricating oils may contain alkali. DO NOT get the substance in eyes and avoid prolonged
or repeated contact with skin. DO NOT swallow. If ingested, seek immediate medical attention. DO NOT induce
vomiting. In case of contact, immediately wash skin with soap and water. In case of harmful contact, immediately
contact a physician. Always keep any chemicals OUT OF REACH OF CHILDREN.
