User Manual | Excel G-Explorer

4. User instructions

It is very important that you teach yourself the correct user instructions. Therefore, you need to know all the components of the wheelchair as described in this user manual. Always check with an expert about developing safe methods regarding your physical abilities to use your wheelchair.

4.1 Balance

Daily operations such as getting in and out of the wheelchair, reaching and bending in the wheelchair will cause change to the weight distribution and the centre of gravity of you and your wheelchair. You will need to perform these movements and techniques as shown below.

4.1.1 Getting in and out of the wheelchair

Getting in and out of the wheelchair is a common operation. The diculties of getting in and out depend on your

physical capabilities. In this user manual, we describe the actions that must be followed when you want to get in or out of the wheelchair without help. When you can’t do it independently any longer, we recommend that you make an appointment with an occupational therapist to discuss your options and to determine how you can best get in and out of the wheelchair.

Getting in the wheelchair

Before you get in your wheelchair, you must make sure the wheelchair is on a at surface, the wheelchair must have the brakes applied and the leg rests need to be ipped sideways. Make sure you are as close as possible to the

wheelchair and the castors are in the forward direction. Now you can, leaning on the armrests, make the transfer to the wheelchair.

Getting out of the wheelchair

When you want to get out of the wheelchair, you must follow the same instructions for getting in to the wheelchair. Make sure you are as close as possible to the wheelchair and put the castors in forward direction. Also, the brakes

must be applied and the leg rests need to be ipped sideways. Now you can, again, leaning on the armrests, make

the transfer out of the wheelchair.

4.2 Bending and/or reaching

It may occur when you are in your wheelchair that you need to reach something. This can be in any direction. To avoid tipping your wheelchair over you must follow the steps below.

4.2.1 Bending and/or reaching forwards

If you want to get something that is in front of your wheelchair, please follow the steps below.

• Make sure that you are as close as possible to the object;

• Make sure the front wheels are facing forward. If not, go forwards and then backwards to turn the wheels fully

to the front;

• Make sure the wheelchair brakes are applied on both sides;

• You can now move towards the target, with caution to keep the wheelchair from falling.

4.2.2 Bending and/or reaching to the side

If you want to get something that is next to you or your wheelchair, please follow the steps below.

• Make sure you are as close as possible to the object with your wheelchair. Use the rear wheels of the wheelchair as a target;

• Make sure the front wheels are turned forward. If not, go forwards and then backwards to turn the wheels fully to the front;

• Make sure the wheelchair is put on the brakes on both sides;

• You can now move to the side without the risk of losing balance. Make sure you move along the wheelchair as

close as possible while lifting the item.

4.2.3 Bending and/or reaching backwards

If you want to get something that is behind you or your wheelchair, please follow the steps below.

• Make sure you are as close as possible to the object with your wheelchair. Make use of your rear wheels. For example, place it against a closet;

• Do not put apply the brakes. If you lose your balance you are better o rolling backwards then ipping backwards;

• You can now bend backwards without the risk of losing balance. But do not bend backwards too far. Then the

wheelchair will tip backwards.

4.3 Going up and down kerbs and thresholds

It may happen that you have to go up or down a kerb or threshold with your wheelchair. In addition, we describe in

this user manual rst how to do this independently and then how you can do this with an attendant.

4.3.1 Going up a kerb or threshold

If you want to go up a kerb or threshold you have to do it in a forward motion. Make sure your weight is, as far as it is possible, is brought forward by bending over. By now making a so-called “wheelie”, the castors are lifted at the front. This way you can get over a kerb or threshold in your wheelchair.

Warning

You should only go up a kerb or threshold after you have discussed with a specialist, such as an occupational therapist, how to do this best.

You can also go up a kerb or threshold with your attendant. This can be done in two ways.

1. Your attendant should place the wheelchair in a forward motion for going up a kerb or threshold. By pressing

down on the handles, the castors at the front wheel will come o the ground. Simultaneously, your attendant should put his foot on the so-called stepper. This will create a leverage eect so the wheelchair can be pushed

up a kerb or threshold.

2. Your attendant should reverse the wheelchair when going up a kerb or threshold. By sitting as far back as possible in the wheelchair and slightly tilting the wheelchair backwards, your attendant can pull the chair up a kerb or threshold. Your attendant should not lower the wheelchair until the castors are on the kerb or threshold.

User Manual | Excel G-Explorer

4.3.2 Going down a kerb or threshold

If you want to go down a kerb or threshold yourself, you should always do this backwards. When you do this forward, there is a risk of falling out of your wheelchair. However, you should practice with an occupational therapist before you go down a kerb or threshold with your wheelchair yourself.

We advise you to go down a kerb or threshold with your attendant. Your attendant should push your wheelchair to the edge of the kerb or threshold. Now the user has to sit back and the attendant has to tilt the wheelchair backwards. When the wheelchair is balanced your attendant can slowly push the wheelchair down a kerb or threshold. The wheelchair should only be pushed further if the castors touch the ground again.

4.4 Going up and down inclines

Most people can climb a short and not too steep incline itself. This depends on your physical capabilities and the degree of the incline. Most people also develop methods to go up and down an incline. If it is necessary you should stop during going up or down the incline, do not make sudden movements that can cause you to fall over.

Tip

Make sure the incline is inspected to climb up and down. That way you will know what to expect and you can safely go upwards or downwards.

4.4.1 Going up an incline

When you go up an incline yourself, we advise you to bend your upper body forwards. This allows you to transfer the heaviest point forward which is the best position to perform this task. We also recommend you to attach the anti-tip to the wheelchair when going up an incline. This will increase the safety during going up an incline. It is also important you don’t carry extra weight such as bags on your wheelchair. This changes the centre of gravity to behind the wheelchair and with that, the chance of tipping increases.

If your attendant pushes you up, he or she must be aware that sucient strength is required.

Warning

Always be careful when getting up and down an incline. An incline steeper than 5° is already dangerous to go up or down with your wheelchair.

4.4.2 Going down an incline

Make sure that the footrests of the wheelchair are at least seven centimetres away from the ground. You should always be facing forward. However, never lean forward when you go down an incline. This may result in a forward tilt of the wheelchair. In order to increase the stability it is better to slightly lean backwards.

To maintain control over your wheelchair, it is important you do not go down too quickly. You can control the speed by the amount of grip that you apply to the hand rims. That will cause the hoops to slide through your hands and will also cause friction. To avoid a friction burn on your hands, we recommend wearing gloves. Do not use the wheel brakes whilst going down the incline. These brakes are only suitable for use when stationary. It is also advisable to avoid suddenly changing the direction when negotiating an incline. This increases your chance of falling over.

If your attendant supports you when going down an incline, he or she must be aware that considerable traction should be exercised.

4.5 Going up and down stairs

Stairs are one of the largest obstacles for people who use a wheelchair. However, it is possible, together with two

attendants; to go up and down a ight of stairs with your wheelchair. You and your attendants must be aware of the

rather heavy weight which has to be moved.

4.5.1 Going up a ight of stairs

When you want to go up a ight of stairs, you need to go up backwards. We advise that if you want to climb the

stairs with a wheelchair you should do this with the help of a minimum of two attendants. With one attendant at the front of the wheelchair, and one at the back. The attendant at the back of the wheelchair holds the push handles and lets the wheelchair tip backwards until it is balanced. When the chair is balanced the attendant at the front of the wheelchair needs to grab the side frames. You are now in position to climb the stairs. The attendant at the

front pushes the side frames up until they are above the rst step and the attendant at the back takes the rst

step on the stairs. Repeat this technique until the last step of the stair. You can let the front castors down when the attendant at the front has taken the last step.

Warning

If you go up a stairway with your wheelchair, you should take a maximum of one step at a time. This prevents the risk of falling down the stairs in your wheelchair.

User Manual | Excel G-Explorer

4.5.2 Going down a ight of stairs

To go down a stairs you basically follow the same operations as going up the stairs. One attendant at the front of the wheelchair and, one attendant at the back of wheelchair. The attendant at the back of the wheelchair grabs the push handles and lets the wheelchair tip backwards until it is in balance. When the chair is in balance the attendant at the front needs to grab the side frames. You are now in position to descend the stairs.

Now, the attendant at the front lifts the side frames until they are above the rst step and the attendant at the back makes the rst step on the stairs. Repeat this technique until the last step of the stair. You can let the front castors

down when the attendant at the front has taken the last step.

Warning

Please be aware; the footrests are not built for lifting, carrying the wheelchair with, they are removable and an accident will occur.

8 Maintenance

Your G-Explorer wheelchair needs periodical maintenance. This is necessary for the upkeep of the moving components. A badly maintained wheelchair will give you technical problems, make it harder to steer and it won’t be covered by the warranty. Preventative maintenance is very important. We advise your wheelchair is checked by

a qualied Van Os Medical dealer at least once a year. This dealer will replace where necessary only Excel parts.

These annual inspections will make sure your wheelchair can function correctly for years.

There are a lot of things you can do yourself to keep your wheelchair in optimum condition. If you regularly check the wheelchair and perform (small) maintenance tasks, this will extend the lifetime of your chair and increase the ease of use. In the following paragraphs these maintenance steps are further described.

8.1 The tyres

You need to check the tyres of the wheelchair regularly. If the wear is at an advanced stage, then you should replace the tyres.

8.1.1 Air tyres

Air tyres should be checked weekly for correct tyre pressure. If the tyres of the wheelchair do not have the correct

pressure it will lean to the side where the lower pressure is. It will also aect the ride and it will mean you have to exert more eort to move the wheelchair.

8.1.2 PU tyres

More and more we use PU tyres (polyurethane or puncture-free tyres) on our wheelchairs. You can easily recognise these tyres as they do not have a valve. PU tyres have the advantage that they do not need to be pumped up and cannot be punctured. The PU tyre tread can wear out just as an air tyre can. Check periodically to see if the tread is still deep enough.

8.2 The brakes

Before you can check the brakes, you need to make sure the tyre pressure is correct. Inspect both brakes for sharp edges. If any are present we advise you to replace them. Ensure that all the parts of the brake are in the correct position and securely fastened;

Make sure that the mechanism is functioning smoothly. If it is not functioning smoothly apply some oil to the

moving parts with one or two drips of WD40 or Teon. Remove surplus oil and dirt. Also, make sure the brakes do

not come into contact with the wheels as you are moving.

8.3 The cross brace

The cross brace underneath your seat is the basis of your wheelchair. Therefore, the cross brace should be in good condition. Check the cross brace at the following points:

• Make sure the wheelchair can easily be folded and unfolded;

• Make sure the wheelchair travels in a straight line while moving;

• Make sure the cross frame is not bent and shows no signs of wear.

When any of the above points show abnormalities, please contact the dealer where you bought the wheelchair. Only your dealer may make any repairs to the cross brace.

8.4 The rear wheels

You can also check the rear wheels yourself. Proper adjustment of the rear wheels increases stability. Also, it makes the chair easier to manoeuvre. Use the steps below to check the rear wheels on the following:

• Make sure that the wheels can move freely without touching anything;

• Make sure there is no play on the rear wheel bearings. If this is the case, this is often that the housing of the

rear wheels is loose.

When any of the above points show abnormalities, please contact the dealer where you bought the wheelchair. Only your dealer may make any repairs to the rear wheels.

8.5 The castors and front fork

The castors at the front of the wheelchair, and the front fork that the castors are attached to must move smoothly and freely to enable you to steer your wheelchair. Check the castors and the front fork for the following points:

• Make sure the nut of the front fork is neither too lose or too tight. When the nut is too loose, the wheels will rotate but the ride will be uncomfortable. If the nut is too tight, the chair will be dicult to steer because of

the bearings getting pushed so the balls cannot move freely. When the nut has the correct amount of tension, the front wheel will stop slowly;

• Make sure the front castor shows no wear signs.

When any of the above points show abnormalities, please contact the dealer where you bought the wheelchair. Only your dealer may make any repairs to the castors or the front fork.

8.6 Upholstery

The upholstery of your wheelchair is also an important component. Torn or worn upholstery can not take human weight anymore and this can be dangerous. Regular monitoring of your upholstery is very important. Check the upholstery of your wheelchair therefore on the following points:

• Check the textile coating for holes, cracks and general wear and tear;

• Check the upholstery-mounting grommets to make sure that they are all correctly aligned and secure.

When any of the above points show abnormalities, please contact the dealer where you bought the wheelchair. Only your dealer may make any repairs to the upholstery.

8.7 Cleaning of the wheelchair

Cleaning your wheelchair is important and should be done regularly. You can get your wheelchair best cleaned as described below.

• Clean the upholstery, chassis and plastic components on the wheelchair regularly with a mild soap and water. Never use abrasive cleaners, they can damage the varnish. Also never use steam or high pressure cleaners;

• Wax the varnish of the chassis regularly. Never use solvents, abrasive waxes, caustic chemicals or spray silicone;

• Dry the wheelchair after cleaning. Also dry your wheelchair after you have been, for example, in a rainstorm.

8.8 Periodical maitenance to your wheelchair

Preventative maintenance is very important and many of these things you can easily do yourself (or your attendant). We have highlighted below the maintenance you can do yourself.

Every week

• Check tyre pressure.

Every month

• Check the fold ability of the wheelchair;

• Check if the quick release rear wheels work properly;

• Check upholstery for wear;

• Check wheel movement front and rear and check turn ability of the wheels;

• Check if the brakes are working correct.

Every three months

• Check all bolts, screws and nuts and tighten if necessary;

• Check all spokes for tension;

• Check tyre tread for wear.

Tip

Make sure the nut is securely fastened through the castor to the fork. You can check this by spinning the castor. The castor must stop slowly.
