Risk Of Death From Lowering Vehicle When Working Between Wheels And Body. Risk Of Injury From Pinching Or Crushing When Working On The Air Suspension. - AS32.22-Z-0001-01A

Model All (Heavy transporter, Light transporter) 

Testing and repair work between the wheel and wheel arch or in the wheel well should only be performed if the vehicle is secured using suitable support fixtures to prevent it from lowering. 

Adjustment operations should only be performed from underneath the vehicle. Use only suitable support fixtures to secure the vehicle frame or vehicle axles in order to prevent them from lowering. 

If necessary, additionally use suitable support fixtures in order to prevent other moving vehicle parts that are in the working area from lowering, or use suitable retaining devices to prevent these parts from moving suddenly and without warning. 

Secure areas with moving vehicle parts against unauthorized access.

Notes on risk of injury and safety instructions/precautions added.

Risk of death 

If the air suspension system is defective, sudden pressure loss may cause the vehicle to lower quickly on its own. This can result in life-threatening injuries caused by trapping and crushing.

Adjustment operations to the air suspension system may result in an aeration or ventilation of the air suspension bellows or lift bellows and thus in a lifting or lowering of the vehicle or individual axles. This can create an unclearly defined danger area.

Risk of injury 

Reaching into the area of the axle suspension or level control system during adjustment operations or with a defective compressed air system can result in serious injuries.

During adjustment operations or in the case of a defective compressed-air system, serious injuries can occur to persons located in the immediate vicinity of the air suspension bellows or lift bellows.

Safety instructions/precautions 

• Testing and repair work between the wheel and wheel arch or in the wheel well should only be performed if the vehicle is secured using suitable support fixtures to prevent it from lowering
• Adjustment operations should only be performed from underneath the vehicle
• Adjustment operations should, to the extent possible, be performed with switched off ignition and/or fully depressurized compressed-air system
• Use only suitable support fixtures to secure the vehicle frame or vehicle axles in order to prevent them from lowering
• If necessary, additionally use suitable support fixtures in order to prevent other moving vehicle parts that are in the working area from lowering, or use suitable retaining devices to prevent these parts from moving suddenly and without warning
• Secure blind hazard areas against unauthorized access using appropriate shielding (e.g. barriers, safety guards)
