Maintenance & Service

While the JB-3 is built to be as indestructible as possible, it should be maintained and may need to be thoroughly cleaned to keep working like new.

Maintaining your JB-3:

  1. Your JB-3 Leg Bag Emptier requires almost no maintenance. Periodic cleaning of the Valve Body and Plunger in warm soapy water is all that is needed to keep the valve functioning properly. See “Cleaning the Clamping Area of the Valve Body” in the “Troubleshooting” section (Page 14). 

  2. The only adjustment required is to the clamping force by use of the Adjustment Screw/Cable Sheath Assembly (Figure 2, Items 3 and 4) . If there is still dripping after tightening the clamping force 2 full turns, then there is something else wrong that is causing the dripping and you should refer to the “Troubleshooting” section (Page 13).

  3. Often a simple slight pull of the Black Drain Tubing to straighten and align it in the clamping area is all that is required to stop minor leaks.

  4. The JB-3 Leg Bag Emptier is made of Delrin, polycarbonate, nylon, and stainless steel. The plastics were chosen for their lightweight and chemical resistance properties. Be very careful not to damage the plastic components of your JB-3 Leg Bag Emptier. Screwdrivers or pliers can mar or damage the plastic components and lead to failures.

  5. Do not put the Cable under the seat or where the tilting mechanism may damage it. If the Cable is crushed, the result is resistance when being activated and leaking when released.

  6. Make sure the drain tubing is not crimped above the Valve Body. Crimped tubing can cause a significant increase in the time it takes to drain your bag.

  7. To prevent accidental breakage, please don’t force the Belt Loop onto objects wider than ¼ of an inch. If you need to attach the Belt Loop around objects that are thicker than ¼ of an inch, like part of your wheelchair frame, use the supplied Velcro® Strap to wrap around the wheelchair frame, then slip the Belt Loop onto the Velcro® Strap. Refer to Figures 15 and 16.

  8. To help prevent the “C” Bracket from breaking, it is best to slip the “C” Bracket onto the Valve Body from the tapered end, and then slide it up until it clicks into place. To remove the “C” Bracket, reverse the procedure. This eliminates excessive spreading of the plastic.

Need to repair your JB-3?

Request a repair if any part of your JB-3 is broken and you are either not comfortable participating in the core-exchange program OR your JB-3 is more than 1 year old and it is no longer covered under warranty. 

If your JB-3 is older than 1 year, you may still participate in the core exchange program but you will be charged (parts and labor) depending upon the condition of your returned core: the cost will be between $49 (assuming all parts are able to be remanufactured) and $119 (assuming none of the parts can be remanufactured) .

The cost of the repair is dependent on the type of damage found. If we need to replace the main components of the valve body due to accidental misuse or damage due to use NOT in accordance with the Instruction Manual, we will charge the following:

    • Clamp body – $48
    • Plunger – $28
    • Adjustment screw – $14
