Use only with effective chip  guarding and personal protective equipment (goggles/shield, gloves, etc.).  • Do not touch hot exhaust system components with bare hands. Severe injury will result.  • Gloves must be worn whenever handling winch cable. Severe injury may result.  • Seatbelts are to be replaced as a set. Failure to do this may cause injury to personnel or damage to  equipment.  • Direct all personnel to stand clear during any hoisting operations. A heavy, swinging load can be  extremely dangerous. Failure to do so may cause injury to personnel or damage to equipment.  • Diesel fuel is highly flammable. Do not perform any procedure near fires, flames, or sparks. Severe  injury or death may result.  • Ensure engine compartment is free of all tools and working material before starting engine. Failure to do  this may cause injury to personnel or damage to equipment.  • Do not remove surge tank filler cap before depressurizing system when engine temperature is above  190°F (88°C). Steam or hot coolant under pressure will cause severe burns.  • Do not drain oil when engine is hot. Severe injury to personnel will result.  • Allow transmission/transfer case to cool before performing maintenance.

Ensure adequate ventilation whenever R-134a is being  discharged. Personnel with a history of cardiac rhythm abnormalities should be made aware of potential  aggravation as a result of exposure to R-134a. Failure to do so may result in injury to personnel.  • Air-conditioning system must be discharged prior to replacing components. Failure to do this may result in  injury to personnel or damage to equipment.
