TOWING EQUIPMENT OWNERS: Make sure all operators of your equipment read and understand this information before towing. Save for reference. This will help you properly select, use and maintain your towing equipment. Refer to owner’s manuals for your tow vehicle, trailer, and other parts of your towing system. Learn the capabilities and limitations of each part. 

GROSS TRAILER WEIGHT and TONGUE WEIGHT are two of the most important items to consider. 
THESE WEIGHTS MUST NEVER EXCEED THE LOWEST RATING OF ANY PART OF YOUR TOWING SYSTEM.

GROSS TRAILER WEIGHT is the weight of the trailer plus all cargo. Measure Gross Trailer Weight by putting the fully loaded trailer on a vehicle scale.

TONGUE WEIGHT is the downward force exerted on the ball by the trailer coupler. Measure Tongue Weight with the fully loaded trailer on a level surface. The coupler must be at its normal towing height. Use a  commercial scale or a bathroom scale. Set up the bathroom scale as shown for heavy tongue weights. 

TRAILER HITCHES, RECEIVERS AND BALL MOUNTS 
Select these products by their gross trailer weight and tongue weight ratings. Select hitches and receivers for specific vehicles. Match the products according to the anticipated use. Use only those products designed for your vehicle.

HITCH BALLS Select by gross trailer weight rating, mounting platform thickness and hole size, and coupler socket size. Do not mix one class of hitch with another class of coupler. Platform must be at least 3/8 inches thick. Hole must not exceed threaded shank diameter by more than 1/16 inch. Use lock washer. Tighten per instructions. When tightened, shank must protrude beyond bottom of nut. Gross trailer weight rating and ball diameter are marked on hitch balls.

TRAILER COUPLERS 
The coupler socket should be smooth, clean and lightly lubricated.1ighten or adjust per coupler manufacturer's instructions. Use proper class type.

SAFETY CHAINS Connect safety chains properly EVERY TIME YOU TOW. Cross chains under coupler. This is done to cradle the trailer tongue in the event the ball and coupler separate. Attach securely to the hitch or two vehicles so they can't bounce loose. Leave only enough slack to permit full turning. Too much slack may prevent chains from maintaining control if other connections separate. Don't let chains drag on the road. 

TRAILER LIGHTS, TURN SIGNALS, ELECTRIC BRAKES AND BREAK AWAY SWITCH CONNECTIONS 
Make these safety-critical connections EVERY TIME YOU TOW, no matter how short the trip. Check operation, including electric brake manual control, before getting on the road.

SWAY CONTROLS Sway controls can lessen the effects of sudden maneuvers, wind gusts and buffeting caused by other vehicles. We recommend them for trailers with large surface areas, such as travel trailers. Adjustable friction models can help control trailers with low tongue weight. Recommended tongue weight is 10% of gross trailer weight.

OTHER USEFUL EQUIPMENT AIR SPRINGS, AIR SHOCKS or HELPER SPRINGS are useful for some hitch applications. A TRANSMISSION COOLER may be necessary for heavy towing. Many states require TOWING MIRRORS on both sides.

TIRE INFLATION Check often. Follow tow vehicle and trailer manufacturers' recommendations. Improper tire inflation can cause trailer sway. 

CHECK YOUR EQUIPMENT / REPLACE WORN PARTS 
Check ball, coupler, chains, retaining pins and clips, and all other connections EVERY TIME YOU TOW. Re-check at fuel and rest stops. 

SAFE TOWING TIPS
 
NO PASSENGERS IN TRAILERS 
Never allow people in trailers while towing, under any circumstances.

TRAILER LOADING Proper loading helps prevent sway. Place heavy objects on the floor ahead of the axle. Balance the load side-to-side. Secure it to prevent shifting. Tongue weight should be 10-15 percent of gross weight for most trailers. Too Iowa percentage of tongue weight can cause sway. NEVER load the trailer rear-heavy. LOAD THE TRAILER HEAVIER IN FRONT.

DRIVING The additional weight of a trailer affects acceleration, braking and handling. Allow extra time for passing, stopping and changing lanes. Severe bumps can damage your towing vehicle, hitch and trailer. Drive slowly on rough roads. STOP AND MAKE A THOROUGH INSPECTION IF ANY PART OF YOUR TOWING SYSTEM STRIKES THE ROAD. CORRECT ANY PROBLEMS AND REPLACE ANY DAMAGED PARTS BEFORE RESUMING TRAVEL.

CHECK FOR EXCESSIVE SWAY AND ELIMINATE IT 
Excessive sway can lead to loss of control. Sway motion should settle out quickly. Sway tends to increase on a downgrade. Starting slowly, increase speed in gradual steps. If sway occurs, adjust your trailer load and equipment. Repeat until the trailer is stable at highway speed. Do this whenever your trailer loading changes.

IF YOUR TRAILER SUDDENLY STARTS TO SWAY Turbulence from another vehicle, a wind gust, or a downgrade can cause sudden sway. So can a shift of the trailer's load or a trailer tire blowout. IF THE TRAILER SWAYS, IT IS THE DRIVER'S RESPONSIBILITY TO ASSESS THE SITUATION AND TAKE APPROPRIATE ACTION. Below are suggestions that may apply, depending on conditions.
 
DO

• Reduce your speed gradually-

• Hold the steering wheel as steady as possible.

• If your trailer has electric brakes, apply the trailer brakes alone, without using the tow vehicle's brakes.

DON'T

• Don't hit your brake pedal hard unless absolutely necessary. A "jackknife" can result.

• Don't try to steer out of the sway condition. Sudden or violent steering can make it worse.

• Don't speed up. Sway increases as you go faster.

• Don't continue towing a trailer that tends to sway. You may lose control during an emergency maneuver or if the conditions listed above occur.

DANGER 
DO NOT MODIFY PRODUCT. TOWING VEHICLE MUST BE IN GOOD CONDITION. USE ONLY FOR TRAILER TOWING AND/OR ATTACHMENT OF TOWING PRODUCTS INC. ACCESSORIES. DO NOT EXTEND ORIGINAL STRUCTURE. DO NOT TOW ONE TRAILER BEHIND ANOTHER, WHICH MAY CAUSE LOSS OF CONTROL. FAILURE TO HEED WARNINGS AND FOLLOE INSTRUCTIONS MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH, VEHICLE CRASH, AND/OR PROPERTY DAMAGE.
 
DON'T OVERLOAD ANY PART OF YOUR TOWING SYSTEM
