### Critical Equipment

As established in the Dealer Sales and Service Agreement, in addition to required essential service tools, the dealer agrees to provide such other tools and equipment as reasonably necessary to fulfill its responsibilities to properly diagnose and service General Motors vehicles. This bulletin is intended to provide General Motors dealerships with requirements and recommendations for service equipment that has been identified as critical equipment necessary to properly repair and maintain General Motors vehicles. The proper maintenance and/or replacement of existing equipment with General Motors approved equipment (available through GM Dealer Equipment) will ensure proper serviceability and contribute to improved customer satisfaction and dealer profitability.

### Equipment Maintenance

Regular maintenance and calibration is essential to assure the use of equipment results in high quality and satisfactory repairs. Most manufacturers recommend weekly or monthly cleaning and inspection of equipment with repair or replacement of worn or damaged parts as needed. Annual or semi-annual calibration of equipment is also recommended, depending on frequency of use. The manufacturer of your equipment will have specific recommendations and, in many cases, can provide inspection and calibration services.

#### Business Grade PC Specifications

PCs that are not business grade are considered "non-supported hardware". Unlike a home grade PC, a business or commercial PC is specifically configured for use in a business network environment. PCs in this class have components designed and supported for use in a network environment. Additionally, they have greater life cycle stability due to "designed-in" serviceability. Techline applications will not function properly on typical non-business grade hardware.

#### Desktop PCs

Important: Reference these specifications when buying new PCs for the Service Department
