To Manually Extend or Retract Ramp:

1.Turn (loosen) the manual release “T” handle 90°.

2.Pull the “T” handle fully out- ward (3" to 4").

3.Turn (tighten) the “T” handle 90° to secure handle in the dis- engaged (unlocked) position.

4.Verify mechanism is disen- gaged (unlocked).

5.Carefully move the platform in or out to desired location using the platform Hand Hold (see Figure E).

Note: Minimal physical effort is required to manually operate the ramp. Slow steady motion results in the least resistance and easy operation. The faster you attempt to manually operate the ramp, the greater the resistance.
