FORD 2011 F-550 v.3 - Manual (Page 256)

• Be prepared for trailer sway due to buffeting when larger vehicles
pass in either direction.
• If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lubricant if not already so
equipped. Refer to Maintenance product specifications and
capacities in the Maintenance and Specifications chapter for the
proper axle lubricant. Remember that regardless of the rear axle
lubricant used, do not tow a trailer for the first 500 miles (800 km) of
a new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full-throttle starts.
Loading
• Trailer loads should be evenly distributed front-to-back and
left-to-right.
• Never exceed truck, trailer, receiver, ball, tongue, tire or coupler
loading recommendations.
• Keep the center of gravity low for best handling.
Braking
• Anticipate stops; allow more distance and time to stop than normal.
• Do not apply the trailer brakes for extended periods of time as they
can overheat and lose effectiveness.
• The trailer brakes (including the shoes, drum and trailer brake
magnets) must be inspected and serviced at intervals specified by the
manufacturer.
• Electric brakes also require periodic adjustment to keep the shoes
properly spaced. If the brakes get hot when driving or if they will not
hold, chances are that they need adjustment.
Backing-up
• Practice backing-up, particularly if you are a novice. Turn the steering
wheel to the right to move the trailer’s rear end to the right.
• Sharp steering movements may cause the trailer to jackknife or go out
of control.
Tires
• Select tires that meet the trailer loading requirements.
• All trailer tires should be of the same size, and construction.
• Always check tow vehicle and trailer tire pressure before towing.
