1. Safety

General safety advice for using a wheelchair applies. Follow this advice to ensure

your personal safety and that of others around you when using Loopwheels.

WARNING

At high speed you could lose control of your wheelchair and overturn.

– Don’t exceed the statutory and advisory speed limit for the place you are in and

in any event don’t exceed speeds of 25km per hour .

– Avoid collisions in general.

WARNING

Risk due to driving style being unsuitable for the conditions

- There is a risk of skidding on wet ground, gravel or uneven terrain.

– Always adjust your speed and driving style to the conditions (weather, surface,

individual ability and experience).

WARNING

Loopwheels™ are not intended for use for passenger transport in a motor vehicle.

– Transfer into a fitted vehicle seat.

WARNING

Risk of serious injury from unexpected wheel braking

– Loopwheels™ must not be used with a rigid guard over the top of the tyres

unless there is a gap of 30mm between the guard and the tyre. There is a risk that,

whilst moving, the wheels could touch the guard and cause sudden braking.

- Check there is a space of 30mm above the tyre at all times

CAUTION

There is a risk of getting fingers, arms or items of clothing caught in the moving

wheel, between the wheel and the chair, or in removable parts such as the axle.

– Make sure when fitting and using Loopwheels™ that nothing becomes caught.

2. Product Identification

Each wheel has a unique identification number on the hub to enable traceability.

3. Components

3.1 Overview of components

Loopwheels™ Urban and Loopwheels™ Extreme are wheels with integral

suspension for use with manual wheelchairs.

Each wheel comprises the following components:

Your wheel may differ slightly from the diagram as each Loopwheel is

manufactured individually to the specifications in the order.

3.2 Note on bearings

The bearings are fixed and bonded into the wheel hub.

DON’T ATTEMPT TO REMOVE OR CHANGE THE BEARINGS YOURSELF!

Seek advice from us about the correct procedure for removing bearings from

Loopwheels™.

4. Accessories

4.1 Tyres

We recommend a pneumatic tyre such as Schwalbe® Marathon Plus tyres for

use with Loopwheels™.

We do NOT recommend the use of solid tyres: this will invalidate your warranty.

For a Loopwheel Urban, you need a tyre size ETRTO 25-540 or 24 x 1.00 inch

For a Loopwheel Extreme, you need a tyre size ETRTO 47-507 or 24 x 1.75 inch

4.2 Spacers

We provide 2 stainless steel and 1 rubber spacer with each Loopwheel. This helps

ensure a snug fit of the wheels on your wheelchair and helps prevent the wheels

touching the chair. Depending on the model and specification of your chair, you

may or may not need to use these.

5. Fitting Loopwheels™ to your wheelchair.

5.1 Camber

Camber is the angle or slope at which your wheels are mounted to your chair.

Each additional degree of camber adds 1cm to the width of each side of your

chair. But greater camber adds stability, better turning and more space for your

hands. To some extent this is a personal choice. BUT:

• We recommend an optimum camber of 6 to 8 degrees for Loopwheels™

Urban and Extreme.

• Loopwheels™ must not be mounted at a camber angle that exceeds 12

degrees.

5.2 Fitting Loopwheels™ to your wheelchair for the first time

Note: you must sit somewhere other than your wheelchair to remove your old

wheels and to fit Loopwheels™!

STEP 1. Release the brakes.

STEP 2. With one hand, hold the wheelchair upright.

STEP 3. With the other, remove your old wheels from the wheelchair by pressing

the centre of the axle.

STEP 4. Remove the existing axles from your old wheels. You can choose to re-

use these or use new axles with your Loopwheels™.

STEP 5: Push one axle into each Loopwheel™ from the outward facing side of

the wheel.

STEP 6. Insert the axle (with the wheel on it) into the axle housing on your

wheelchair, one side at a time.

STEP 7: Rotate the wheel slowly to check that no part of the Loopwheel™

touches or rubs the frame of the chair. We recommend a minimum clearance of

10mm at all points.

In addition, there must be a space of at least 30mm above the wheel.

If the clearance is good, move to STEP 11.

If there is a clash or not enough clearance, move to STEP 8.

10mm

30mm

STEP 8: Remove the Loopwheel from the chair, place one of the steel spacers

onto the axle from the INNER side of the wheel. This will move the Loopwheel

further away from the wheelchair frame.

Repeat Steps 7 and 8 up to a maximum of 3 times until there is the correct

amount of clearance between the wheel and the frame of the chair.

STEP 9: Secure the steel spacers in place by sliding the rubber washer onto the

Loopwheel™ axle.

STEP 10: Replace the wheels onto the chair.

STEP 11: Check that the removable axles are fully engaged in the axle housing of

the wheelchair.

STEP 12: Check that the brakes still engage properly with the tyre. If they do not,

seek advice from your wheelchair supplier or therapist on re-positioning the

brakes.

5.3 Removing Loopwheels™ from your wheelchair

STEP 1. Release the brakes.

STEP 2. With one hand, hold the wheelchair upright.

STEP 3. With the other, hold the wheel around the wheel hub.

STEP 4. Using your thumb, press the removable axle button and hold it down.

STEP 5. Pull the axle out of the wheelchair axle housing
