Adjustment Instructions

The Roll-A-Bout is a piece of medical equipment.  It will be an extension of your leg to support your weight when standing or walking.  It is very important that the unit is properly adjusted and fits correctly.  When standing erect, your good leg should be straight.  The knee of your injured leg should be resting comfortably in the center of the square knee (front) cushion.  There should be equal pressure on your good foot and the knee of the injured leg.  Your hips must be level with your back straight.  If the unit is too high, too low, or for the wrong leg, please follow the instructions to adjust the unit properly.

The Roll-A-Bout has two adjustments for height: The Wheels and the Platform

To adjust the Roll-A-Bout in 1" height increments by moving the wheels:

For All Models

First, remove the black hubcaps by prying off the rubber hubcap with the tip of a screwdriver.  Make sure not to go more than 1/8" behind the hubcap to prevent damage to the retaining washer.    Using two ½" wrenches, remove each of the wheels and move them up or down into the desired hole.  Each of the wheels has a different configuration of spacers, washers and location.  Please adjust each wheel independently to be sure the spacers and washers are assembled correctly!  Retighten so the nuts are snug and the bolt protrudes through the nut and the side to side play is taken out of the wheels.  Do not overtighten!  Replace the hubcaps.

To adjust the platform for the RA-250, and the ATV-250 Models ONLY!

(The platform is only adjustable on the RA-250 and ATV-250 models.  All other models (HD-400, HDT-300, HDT-400, ATV-400) must be returned to the place of purchase or rental for the correct model!)

To lower the platform (generally for a person 4'10" to 5'4"), Remove the bolts from the front of the platform and the front frame using a 7/16" socket and a 7/16" wrench, or a 3/16” hex key (allen) wrench and a 7/16” wrench.  Reassemble into the lower set of holes installing the bolt from inside the platform out through the front frame.  Be sure to reassemble using the 1" nylon spacers.  Remove the 1 ¼” bolts, washers and 1/2" spacers from the sides of the platform.  Remove the rear bracket and two side brackets from holes using two 7/16" wrenches.  Reassemble the rear bracket into the lower set of holes using the 1 ¾” bolts, making sure to assemble the side brackets using the hole farthest away from the other two holes.  Using the 1 1/4" bolts, reattach the side brackets from inside the platform out through the side bracket leaving the middle hole unused on both the side bracket and the platform!.  Make sure to replace the ½" nylon spacers and the 1/4" flat washers between the platform and the side bracket.  Retighten so the nuts are snug and the bolt protrudes through the nut.  Do not overtighten!

To raise the platform (generally for a person 5'5" to 6'2"), Remove the bolts from the front of the platform and the front frame using a 7/16" socket and a 7/16" wrench, or a 3/16” hex key (allen) wrench and a 7/16” wrench. Reassemble into the upper set of holes installing the bolt from inside the platform out through the front frame.  Make sure to reassemble using the 1" nylon spacers.  Remove the 1¼” bolts, washers and 1/2" spacers from the sides of the platform.  Remove the rear bracket and two side brackets from holes using two 7/16" wrenches.  Reassemble the rear bracket into the upper set of holes using the 1 ¾” bolts, making sure to attach the side brackets using the hole farthest away from the other two holes.  Using the 1 1/4" bolts, reattach the side brackets from inside the platform out through the side bracket using the middle hole on both the side bracket and the platform!.  The hole farthest from the front of the platform will not be used. The side bracket will have an unused hole farthest from the rear bracket!  Be sure to replace the ½" nylon spacers and 1/4" flat washers between the platform and the side bracket.  Retighten so the nuts are snug and the bolt protrudes through the nut.  Do not overtighten!

To adjust the Roll-A-Bout for the opposite side:

The Roll-A-Bout is designed for use with either a right or left leg injury.  The offset wheels will need to be on the side of the injury.  For example, for a right leg injury, the offset front and rear wheels will be to the right.

Models RA-250 and ATV-250

To rotate the front frame, use a 5/32" hex key (allen) wrench and a 7/16" wrench to remove the two (2) bolts from the hinge (when open, the hinge point is at the top of the front frame, where the front and rear frames meet).  Next, using a 7/16" socket and a 7/16" wrench or a 3/16” hex key (allen) wrench and a 7/16” wrench, remove the bolts from the front of the platform.  Rotate the front frame 180 degrees and reassemble using the same bolts and nuts installing so the nut is on the outside of the frame.  Remove the rear wheels and switch them side for side making sure the wheel with the 1" aluminum bushing is on the outside of the frame, to the side with the injury (the same side as the front offset frame) and the brake wheel is on the inside of the frame.  Remove the Brake Bracket from the frame using a Phillips screwdriver and a 7/16" wrench.  When mounting the Brake Bracket on the opposite side, do not remove the brake from the bracket, but simply loosen the brake from the bracket and rotate the brake 180^, and remount the bracket to the underside of the frame (see photo), keeping the wheel between the brake pads.  To remove the wheels, you must first remove the black hubcaps by prying off the rubber hubcap with the tip of a screwdriver.  Make sure not to go more than 1/8" behind the hubcap to prevent damage to the retaining washer.  For comfort, the brake handle may also be rotated 180 degrees.  The push button parking brake lock will now be on the underside of the brake handle.  Retighten all bolts so they are snug and the bolt protrudes through the nylon locknut.  When tightening the wheels, tighten so the side to side play is taken out of the wheels.  Replace the hubcaps.  Do not overtighten!

Models HD-400, HDT-300, HDT-400 and ATV-400

In addition to the above directions, also remove and reassemble the additional linkage (brackets) when disassembling and reassembling the front frame.
