  • Page 32: Inserting & Removing The Levers

      6.1. Inserting & Removing the Levers  The lever drivetrain provides great outdoor performance but may limit your maneuverability  indoors. We designed the levers to be easy to insert and remove. The levers are interchangeable    and store on the Freedom Chair when not in use.  ...

    It is normal for this to wear out the powder coat on the brake tube. It will not wear down the  tires—in fact, the levers will wear down first. ​ N ote: ​ W hile a worn-off powder coat isn’t a  problem, please contact GRIT if you wear away a hole in the lever itself.   ...
  • Page 41                           Note:​ The brakes engage by coming into contact with the tire.                                   ...
  • Page 42: Turning

      7.2. Turning  Turning the Freedom Chair is similar to turning a rowboat or skid-steer.  To turn, apply the brake on the wheel closest to the direction you want to turn and push on the other  lever. Example: To turn right, apply the right brake and push on the left lever. To turn left, apply the  left brake and push on the right lever.
  • Page 43: Reversing

      7.3. Reversing  The Freedom Chair has a unique ​ h ill-hold ​ b raking feature. Rolling the chair backward rotates  the levers backward, which engages the brakes. This prevents the rider from rolling backward  down a hill.  As a result of the hill lock, however, the Freedom Chair is unable to move backward with the  levers inserted.
  • Page 44: Transferring

      The parking brakes can be adjusted if they seem too loose or too tight. A correctly fit parking brake will  lock the wheel with the minimum pull force required. For more information about our parking brakes,  see: ​ ttps://www.gogrit.us/freedom-chair-support#brakeadjusting   ...

  • Page 46: Climbing Hills

      8.1. Climbing Hills  We recommend using ​ s hort, alternating strokes ​ w hen climbing hills. This makes slow  constant progress up steep hills and helps keep the front wheel planted on the ground.   Some other tips:  • Steady momentum is your friend. Keep a slow and steady pace.  •...
  • Page 47: Curbs

      • Avoid extended periods of descent, as this could overwork the brakes.  • Do not descend hills when the wheels and brakes are very wet or covered in wet mud.  Braking performance decreases when wet.  CAUTION: ​ W ET CONDITIONS DECREASE BRAKING PERFORMANCE. Use  caution when riding in wet conditions.

  • Page 52: Inflating The Wheels

          10.1 Inflating the Wheels  It is important to keep the tires at the recommended pressure to prevent flats caused by  under-inflation. Do not over-inflate the tires.   On soft, sandy ground, riding with lower pressure (but still at or above the minimum pressure)  will provide more traction.
  • Page 53 Both of these adjustments may require you to add or  remove links to the chain in order to keep your center of gravity the same.  For detailed instructions, contact GRIT at ​ s upport@gogrit.us ​ o r 617-356-8106.   ...
