408 STARTING AND OPERATING 5. Cargo capacity will be reduced by the addition of options or passengers, etc. The loaded vehicle weight, including the snowplow system, all aftermarket accessories, driver, passengers, options, and cargo, must not exceed either the Gross Vehicle Weight (GVWR) or Gross Axle Weight (GAWR) ratings. These weights are specified on the Safety Compliance Certification Label on the driver's side door opening. NOTE: Detach the snowplow when transporting passengers. Vehicle front end wheel alignment was set to specifications at the factory without consideration for the weight of the plow. Front end tow-in should be checked and reset if necessary at the beginning and end of the snowplow season. This will help prevent uneven tire wear. The blade should be lowered whenever the vehicle is parked. Maintain and operate your vehicle and snowplow equipment following the recommendations provided by the specific snowplow manufacturer. Over the Road Operation With Snowplow Attached The blade restricts air flow to the radiator and causes the engine to operate at higher than normal temperatures. Therefore, when transporting the plow, angle the blade completely and position it as low as road or surface conditions permit. Do not exceed 40 mph (64 km/h). The operator should always maintain a safe stopping distance and allow adequate passing clearance.
