Failure to install the Alternative Hitch correctly could result in an accident and serious injury. I. Preparing the Burley Trailer If you have purchased a new Burley trailer with the Alternative Hitch as original equipment, proceed beyond to Section II. 1) To remove the standard Burley hitch from the hitch coupler, insert a 1/ 8" hex key into the socket head and, while holding the 3/8" nylock nut with a wrench, rotate the hex wrench counterclockwise. 2) The Burley QR Alternative Hitch includes a 1 3/4" long, 1/4 x 20 bolt, nylock nut and D-ring.

FIGURE 2 Burley Quick-Release Alternative Hitch OP EN 10 3 NOTE: The quick-release skewer must insert a minimum of 11mm into the adjusting nut to function properly. The Alternative Hitch replaces the quickrelease mechanism on the rear wheel. The consumer MUST be thoroughly informed on how to safely operate this and traditional quick-release mechanisms. Proper adjustment of the quick release must be checked before every ride. Never install an Alternative Hitch with standard length safety strap on a mono-stay bicycle. Mono-stay bicycles require an Alternative Hitch with long safety strap that allows the safety strap to be secured around the mono-stay and above the left side cantilever brake stud. Failure to properly attach the appropriate safety strap on a mono-stay bicycle can lead to the trailer separating from the bicycle, resulting in serious injury or death. Failure to properly secure the quick-release mechanism of the Alternative Hitch may lead to an accident resulting in serious injury or death. After completing the Safety Checklist printed on the trailer seat, you are ready to ride. 1) Remove the entire quick-release assembly from the rear wheel of the bicycle. 2) Install the wheel between the dropouts. Make sure that the left dropout is snug against the axle lock nut. Measure the distance that the wheel axle is recessed in the left dropout. If the axle is recessed less than 1. 5mm from the exterior face of the dropout, the Alternative Hitch body cannot engage the dropout properly. You must then remove the wheel and file or grind the hollow axle end. Repeat the measurement and file or grind as necessary to ensure that the axle end is recessed 1. 5mm from the exterior face of the dropout. IV. Maintaining the Alternative Hitch For the Quick Release Alternative Hitch: 1) Check quick-release tension frequently. The composite "ears" are connected to the metal hitch body with a retaining clip. The quickrelease lever is secured to the Alternative Hitch body with an "E-type" retaining clip. This retaining clip is attached to the end of the quick-release shaft opposite the quick-release lever handle. Do not disassemble this retaining clip or your Alternative Hitch mechanism or quick-release mechanism. Never install the Alternative Hitch on a bicycle with an axle end less than 1. 5mm from the face of the left side dropout. An axle less than 1. 5mm from the dropout face will prevent the Alternative Hitch from engaging the dropout properly and lock the wheel in the frame, possibly resulting in an accident and serious injury. Inspect the retaining clips each time you tighten or release the Alternative Hitch quick release. Do not use your bicycle with the Alternative Hitch if the retaining clips are missing or not securely engaged. Failure to maintain the quick-release mechanism may result in an accident resulting in serious injury or death. 3) Loosen and remove the nut and the single quick-release spring from the Alternative Hitch quick-release assembly. 4) Insert the skewer of the Alternative Hitch into the hollow axle from the non-drive side of the wheel as you would a traditional quick-release skewer. [. . . ] c) Place the skewer in a vice and using a suitable metal cutting blade, cut the skewer down to the appropriate length. III. Attaching the Burley Trailer to the Alternative Hitch For Frames with Seat and Chain Stays: 1) Insert the exposed end of the black elastomer coupler into the composite "ears" of the Alternative Hitch (Figure 4). 2) Align the hole in the black elastomer coupler with the holes in the hitch ears and insert the lock pin with attached safety strap (Figure 4). 3) Snap the lock pin closed by pressing the bail wire over the pin end (Figure 4). 4) Wrap the end of the safety strap over the chain stay of the bicycle frame and attach it to the D-ring on the trailer tongue (Figure 4). d) File the end until smooth and back the nut off the skewer to chase the threads.
