FORD 2004 F-550 v.1 - Manual (Page 189)

Snowplowing with your air bag-equipped vehicle
Your vehicle is equipped with a driver and passenger air bag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploy the air bag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag (SRS) is
provided.
Never remove or defeat the “tripping mechanisms” designed into the
snow removal equipment by its manufacturer. Doing so may cause
damage to the vehicle and the snow removal equipment as well as
possible air bag deployment.
Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln Mercury dealer.
Additional equipment such as snowplow equipment may effect
the performance of the air bag sensors increasing the risk of
injury. Please refer to the Body Builders Layout Book for instructions
about the appropriate installation of additional equipment.
Transmission operation while plowing
• Shift transfer case to 4x4 LOW (4WD Low) when plowing in small
areas at speeds below 8 km/h (5 mph).
• Shift transfer case to 4x4 HIGH (4WD High) when plowing larger
areas or light snow at higher speeds. Do not exceed 24 km/h (15
mph).
• Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
