Important Safety Recall This notice applies to your vehicle, Schwarze A-Series CNG (Compressed Natural Gas) Street Sweeper, VIN: —– December 2021 Dear Schwarze Customer, This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Alamo Group Inc. has decided that a danger of fire can occur on certain Schwarze MY 2012-2020 A7 CNG, A8 CNG and A9 CNG street sweepers with horizontal exhaust systems, including the VIN shown above. As a result, Schwarze is conducting this safety recall. We apologize for this inconvenience. We are committed to your safety and satisfaction with our products, and we request that you remedy your vehicle promptly. Why is your vehicle being recalled? What will we do? IMPORTANT • Your street sweeper is involved in a safety recall 21 V-00G to install a tailpipe and hanger to extend and redirect tp.e exhaust behind the sweeping head. • A remedy is available now. • You should contact your local Schwarze dealer or Schwarze’s Warranty Department to arrange for this free remedy. On certain CNG A-Series sweepers, the horizontal exhaust tailpipe may be too short, such that if the operator allows debris to buildup in front of the sweeping head, to where it comes in contact with the exhaust outlet, a fire can occur. Remedy parts are available now. Dealers will install Exhaust Extension Kit (206B93) to add a 56″ exhaust tailpipe, so that the tailpipe extends the exhaust outlet beyond the backside of the sweeping head. . This service will be performed on your vehicle free of charge. The repair takes about 1 hour to complete. What should you do? What if you no longer own the sweeper? What if you have already paid for this repair? Who should you contact if you have further questions or concerns? Please contact your local Schwarze dealer to schedule your remedy appointment. If you are not sure who your local Schwarze dealer is, please contact the Schwarze Warranty Department at 800-879-7934 or warranty@scl1warze.com and we will identify your closest dealer.

In such instances, these materials can come in contact with the chassis exhaust system. In such systems with a short tailpipe, the buildup of materials against the exhaust system may lead to a fire. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : If lightweight materials accumulate against the exhaust system and are not drawn up into the pick-up area, this poses the risk of a fire.

On November 18, 2021 Schwarze was notified by a dealer of a second vehicle fire involving an A-Series CNG sweeper. On December 14, 2021, Schwarze inspected that second sweeper. In the course of its investigation into both events, Schwarze examined manufacturing records for the A-series CNG sweepers. On December 17, 2021, Alamo Group decided to conduct a voluntary safety recall to install a tailpipe extension to any A-Series CNG sweepers in the affected population that do not have a 56” tailpipe. As of December 17, 2021, Alamo Group is aware of no warranty claims and no injuries related to this issue. As to field or service reports, as noted above, Schwarze received on October 15, 2021, a customer report of a fire and received on November 18, 2021, a dealer report of a fire. Part 573 Safety Recall Report 21V-00G Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : Schwarze will provide dealers, free of charge, a kit (No. 206B93) to extend the exhaust tailpipe for all affected vehicles, so that the tailpipe extends the exhaust outlet beyond the backside of the sweeping head.
