Summary

Alamo Group Inc. (Alamo) is recalling certain 2012-2021 Schwarze A7 CNG, A8 CNG, and A9 CNG street sweepers mounted on FreightlinereBay logo M2-112 chassis and equipped with a horizontal exhaust system. Lightweight debris, such as leaves, may build up in front of the sweeping head and accumulate against the chassis exhaust system.

 

Remedy

Dealers will install an exhaust tailpipe extension tube, free of charge. Owners notification letters were mailed on January 14, 2022. Owners may contact Alamo Group customer service at 1-830-379-1480.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

 


REASON FOR THIS SAFETY RECALL:

On December 22, Alamo Group filed a Defect Information Report with the National Highway Traffic Safety Administration (NHTSA) informing the agency that in 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, debris can come into contact with the exhaust outlet. This presents a fire hazard.

 

REMEDY:

Remedy parts are available. Dealers will install Exhaust Extension Kit (206B93). This service must be performed on all affected vehicles at no charge to the vehicle owner. Attached please find the service procedure for completing this repair. The repair takes about 1 hour to complete.

 


Chronology :

On October 15, 2021, Schwarze Industries, Inc. (“Schwarze”), a subsidiary of Alamo Group, was notified by a customer of a vehicle fire involving an A-Series CNG sweeper.

On October 28, 2021, Schwarze, with the support of a third-party fire investigator, examined that sweeper.

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.
