SPECIAL APPLICATIONS
Snowplow Installation/Minimum Required And Recommended EquipmentVehicles Available For Snowplow Applications (Cont�d):4x4 Chassis Cab Models (With Driver And One Passenger)
Completed Vehicle WeightThe weight of the completed vehicle with equipment installed (and second unit body, if applicable) must not exceed the Front GAWR, Rear GAWR, or GVWR established by Ford, with consideration for the driver and one front seat passenger. If sufficient weight is added such that the completed vehicle with a driver and more than one passenger would exceed Front GAWR, Rear GAWR, or GVWR, it is the responsibility of the equipment installer to notify the customer of the appropriate use restrictions. (IE: That the user should limit occupancy of the vehicle to the driver and one passenger while the equipment is installed.) The addition of ballast weight, placed rearward of the rear axle, may be required to prevent front end overloading or exceeding Front GAWR. If required, the ballast weight must be securely attached to the vehicle. For Ford completed vehicles of 10,000 lbs. GVWR or less, the weight of permanently attached equipment must not exceed the Total Accessory Reserve Capacity (T.A.R.C.) as specified on the Safety Compliance Certification Label. Permanently attached equipment includes the snowplow frame-mounting hardware, and does not include the removable snowplow blade assembly. Exceeding T.A.R.C. will require recertification.
Front End Wheel Alignment and Headlight AimFront end wheel alignment (toe) and headlight aim may require readjustment after installation of equipment, and is the responsibility of the equipment installer. Failure to reset front wheel alignment may cause premature uneven tire wear. If required, reset to chassis manufacturer�s specifications found in the Ford Shop Manual.

SPECIAL APPLICATIONSSnowplow Installation/Minimum Required And Recommended EquipmentElectrical ConnectionsInstallation of any inductive load devices (i.e., electric motors, electric clutches for clutch pumps, etc.) MUST NOT be connected to OEM wiring or fuse panels. Power for such devices should be taken directly from the battery or starter motor relay power terminal. Control of these devices should be achieved via relays. No direct current path should exist between OEM wiring and the installed load that is not filtered by the battery. These recommendations are intended to reduce or eliminate any induced reverse voltage into the OEM circuitry.
WarrantyThe Normal Ford New Vehicle Limited Warranty applies to vehicles with snowplows installed in accordance with these guidelines. Consult your Ford dealer or the Owner�s Guide for any further questions.
ComplianceA vehicle that is fully represented by the guidelines in this section will meet all applicable F/CMVSS requirements. Any deviation from this design or manner of installation must be assessed independently from Ford by the snow control equipment manufacturer, or installer, to determine possible F/CMVSS implications. A metal crossmember is included below the front bumper on Super Duty vehicles called a �BlockerBeam�. Warning: Removing the BlockerBeam without installing snowplow attachment hardware may effect air bag deployment in a crash. Do not operate the truck unless either the BlockerBeam or snowplow attachment hardware is installed on the vehicle.
