Tighten the bolts very securely so the arms do not loosen up during use.
c. Remove the Allen screw from the lever clamps (111), fit them onto the handlebar (17) and secure with the Allen screws. Make sure the levers are positioned under the hand position and they are adjusted so the patient can comfortably reach them during use.
