Warning | Risk of poisoning caused by inhaling overheated refrigerant vapors from an air conditioning system containing R134a. Risk of injury to skin and eyes caused by contact with liquid R134a refrigerant and when working on pressurized parts | Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated rooms. Carry out repair work on the air conditioning system circuit only after the system has been evacuated. | |
Warning | Risk of injury to skin or eyes from hydraulic fluid spraying out under pressure.Risk of poisoning from swallowing hydraulic fluid. | Depressurize hydraulic system completely before starting any work on it. Wear protective clothing and safety glasses. | |
Caution | Risk of injury caused by scraping or cutting body parts on sharp vehicle parts | Always wear protective gloves when working on or near sharp and non-deburred vehicle parts. | |
Caution | Risk of poisoning from swallowing brake fluid. Risk of injury from skin and eye contact with brake fluid | Only pour brake fluid into suitable and appropriately marked containers. Wear protective clothing and eye protection when handling brake fluid. | |
