General Motors LLC (“GM”) is excited about the current electric vehicles in its product line-up as well as future GM electric vehicles coming to market (the “Electric Vehicles”). Electric Vehicles require unique training, equipment and tools to properly sell and service them, including a forklift on the GM dealership premises to assist in the safe handling of High Voltage (“HV”) batteries that power Electric Vehicles and vehicle hoists meeting certain specifications to facilitate servicing Electric Vehicles. This bulletin applies to all GM dealers that sell or service Electric Vehicles (“GM EV Dealers”) until further notice or until updated via a subsequent communication and sets forth certain specifications and requirements for (1) the forklift(s) that each GM EV Dealer is required to have on premises to assist in the safe handling of HV batteries, and (2) vehicle hoists to service Electric Vehicles. GM EV Dealers must comply with ALL equipment standards, safety procedures, and rules provided by GM, and all applicable federal, state, municipal, provincial, and local laws, statutes, rules, and regulations pertaining to forklift operating and handling HV batteries. Each GM EV Dealer is responsible for ensuring compliance with all such equipment standards, safety procedures, and rules provided by GM, and all applicable federal, state, municipal, provincial, and local laws, statutes, rules, and regulations. Forklift Properly Trained Personnel Each GM EV Dealer must have a least one (1) employee who is properly trained and licensed to operate a forklift consistent with regulatory requirements in your market on site at the Dealership Premises during all hours of Dealership Operations. ¹GM EV Dealer is responsible for ensuring that the forklift operator is licensed under all applicable federal, state, and local laws and regulations. Required Equipment Due to the size of HV batteries, a forklift meeting the specifications described below is required. Each GM EV Dealer is responsible for obtaining written verification from the forklift manufacturer that the forklift utilized on GM EV Dealer’s premises complies with these requirements. Required Technical Specifications:² ¹Capitalized terms not defined in this bulletin shall have the meaning prescribed to them in the General Motors Dealer Sales and Service Agreement. ² GM strongly recommends, but does not require at this time, that a GM EV Dealer obtain a forklift equipped with (1) a Side Shifting Fork Arm Positioner to assist loading HV batteries into shipping container, and (2) lugged tires for inclement weather or uneven surfaces. Page 2 October, 2022 Bulletin No.: 22-NA-114 Note: Your brand specific Participation Agreement may state 8,000 lb capacity forklift. Some 8,000 lb forklifts may not meet all criteria listed within based on the design and manufacture of the forklift. We recommend providing the following criteria listed within to the forklift manufacturer. • Capacity: lift 4250 lbs. with load center of 48 in., at 142 in. height. • Fork Length: must be at least 72 in. / 1828 mm in length, no extensions allowed (See Figure 1). • Fork Width and Thickness: to accommodate the EL-53080 battery lift system and HV battery crate, fork width and thickness must not exceed the dimensions in the following table: Fork Width (W) Fork Thickness (T) < 6.5“ Up to 3“ Thick 6.5“ — 8“ Up to 2.25“ Thick Forks wider than 8” / 203 mm are incompatible with the EL-53080 battery lift system and HV battery crate.
