Insert the male portion of the wheel axle into the female portion of the axle. The wheels are locked in place when you feel them click into the spring lock on the axle tube. The wheels can be removed simply by pushing the button on the spring lock mechanism on the underside of the axle and pulling them out of the axle tube.The trailer is shipped with the tow bar locked in the storage position underneath the trailer. Unlock it by removing the cotter pin from the swivel joint. Put the tow bar into towing position by swiveling it 180 degrees and snapping it into place in the saddle of the swivel joint. Now lock the tow bar into place by re-inserting the cotter pin.
The sides of the cabin are held in place by means of a roof support rod and two black plastic star knobs. With the wheels resting on the ground, rotate one side panel into a vertical orientation. Position the support rod inside the trailer so one star knob can be inserted through the grommet and frame on the side of the trailer and into the threads on the end of the support rod. Repeat with the other star knob on the other side of the trailer, and fully tighten both star knobs.
The tow bar connects to the bicycle via the included quick-connect hitch. Attach the hitch to the left side of the rear bicycle wheel by removing the axle nut, positioning the hitch on the axle, and re-tightening the axle nut. If your bicycle has a quick-release wheel, remove the quick-release pin from the axle, insert it through the hitch, then re-assemble through the axle. The hitch should be installed with the male connector piece facing back and angling away from the bicycle.
Position the trailer behind the bicycle so that the female connector on the tow bar can slide over the male connector on the hitch. Lock these connectors in place with the cotter pin. Loop the black safety strap around the bike frame and attach the snap swivel to the D-ring on the tow bar.
WARNING: Never tow the trailer without the hitch and hitch safety strap correctly connected. Always make sure the rear door is closed fully before towing the trailer.
Load and unload pets only through the rear door, with the front door closed and the trailer attached to the bicycle. Have someone hold the bicycle firmly in an upright position, or lay the bicycle on its side. With the pet inside the trailer, snap one end of the (included) safety leash to the pet's collar and the other end to the D-ring located inside the trailer. Adjust the length of this leash so the pet cannot exit through the front window when it is open. Always close the rear door before riding.
While loading your dog or accessing the interior of the cabin, the rear door can be kept in the open position by connecting the two hook-tape strips on the inside of the door to the two loop-tape strips located at the top of the cabin, near the back. Always keep this door closed while riding.
The trailer has two front doors: a vinyl windscreen door, and a breathable mesh door. The trailer can be used with one, both or none of these doors open. To ride with the vinyl door open and the mesh door closed, roll up the vinyl door into a tube shape so the loop-tape on the inside of the door connects to the hook-tape on the top of the cabin. To ride with both windows open, roll them up together into a tube shape and connect the hook-and-loop-tapes. Make sure the safety leash is adjusted so the pet cannot exit through the front door opening.
Cleaning - The cloth cabin and windscreen can be cleaned with a damp cloth or sponge. The interior cushion has a removable, machine washable fabric shell.
The trailer is intended to carry pets only. No human passengers.
