Step 1

Choosing & Fitting the Connectors

Check which Connector type will fit your wheels by holding them up to the Wheel Rim. Try each of the 3 shapes, type 1, type 2 and type 3, one at a time. The Connectors should fit snugly around the Wheel Rim with no gaps (Fig A). The type that fits your Wheel Rim best is the one you should choose.

Please note that 25” Spinergy wheels will require Type 1 Connectors.

Using the Assembly Tool, attach one Connector to the end of each of the Wheel Adapter Arms with the Bolts provided.

(The Connector will only fit on one way.)

Rotate the Wheel Adapter until the three Adapter Arms are aligned with areas on the Wheel Rim that are free from obstructions such as Spokes, Hand Rim fixings and Wheel Valves.

Stick the supplied Markers on the Wheel Rim in line with the Adapter Arms (FIG. B).

 

Step 3

Unlocking Wheel Adapter Arms

Located at the base of each Adapter Arm is a black Release Pin (FIG. A).

Step 4

Fitting the Adapter to the wheel

Position the locked Arm over one of the marked positions on the Wheel Rim (FIG. A).

Guide the remaining two unlocked Arms through the Hand Rim and onto the Wheel Rim, these should line up with the remaining two marked positions (FIG. B).

The Connectors should fit around the Wheel Rim easily with no excessive force required (FIG. C).

Once the Connectors are correctly positioned, press the Wheel Adapter towards the Wheel at the base of the three Arms until each Arm locks in place.

 

Step 5

Securing the Adapters

Insert the Adapter Tightening Tool into the Tightening Screw as shown in (FIG. A). Rotate the Tool clockwise until you feel the Wheel Adapter start to tighten. WARNING! DO NOT OVER-TIGHTEN.

Hold the wheel steady with one hand. With your other hand check there is no side to side movement between the Connector and the Wheel Rim (FIG. B). Next, ensure there is no in and out movement (FIG. C).

When the Adapter is correctly fitted there should be no movement between the Connectors and the Wheel Rim or the Adapter and the Wheel. Continue to tighten until correctly fitted.

WARNING! IF THE ADAPTER WILL NOT TIGHTEN, YOUR WHEEL MAYBE TOO BIG – CONTACT YOUR SUPPLIER. THE FIT OF THE ADAPTER SHOULD BE CHECKED EVERY TIME THE Nu Drive SYSTEM IS USED.

 

Step 6

Fitting the Drive Units

WARNING! YOU NEED TO BE CONFIDENT IN YOUR ABILITY TO UNDERTAKE THIS PROCEDURE WHILST SUPPORTING THE WEIGHT OF A DRIVE UNIT.

Ensure you have selected the correct Drive Unit for each side of the wheelchair – the large arrows on the top of the Handles need to point in the direction of forward travel (FIG. A).

Press the Drive Unit into the centre of the Wheel Adapter until it clicks into place (FIG. B), checking that the Drive Unit is secure by pressing it at three points around it’s base. As a safety precaution, move the Levers around to ensure a secure attachment (FIG. C).

The Adapters can be left in place when the Drive Units are removed (see User Instructions).

WARNING! IF YOUR WHEELCHAIR HAS A QUICK RELEASE MECHANISM, MAKE SURE THE LEVERS DO NOT INTERFERE WITH IT DURING FITTING.

When supplied, the Handles will be in their lowest position (FIG. 1).

Using the Assembly Tool, release the Bolts on the inside of each Handle (FIG. 2).
