DESCRIPTION (Fig. 1 and 2)

Panthera U3 light is a dynamic wheelchair designed to let you live life as actively as possible. Meticulous attention has been paid to every detail. The low weight, combined with the stable, fixed frame and easy rolling castors, make the wheelchair extremely easy to manoeuvre. The chassis’ seat angle, along with adjustable backrest and seat upholstery and backrest angle adjustment, combine to provide extremely good seating comfort The fabric used in the backrest upholstery has been carefully selected to provide ergonomic and comfortable seating posture. The wheelchair’s balance point can be adjusted to enable you to find a setting that makes you feel safe and secure.

Panthera U3 Light Y-front Fig. 2 och 3
Gives full frame width for the user’s thighs and then narrows down the frame front to the fixed footplate, where the feet rest together.
Also available as Panthera U3 Light /L Y-front and Panthera U3 Light Y-front 90°, has a right angle, between the frame front and the seat. Otherwise they have the same specifications as U3 LIGHT.
Panthera U3 light, Fig. 1, 2 and 3, U3
Light is a wheelchair designed for the active, advanced user. U3 Light has a ”tippy” balance, easy to lift and transport and also extremely easy to manouver. In standard configuration U3 Light has a rigid rear axle of carbon fibre, lightweight rear wheel, aluminium foot rest, easy rolling castor wheels, arm brake, and a seatbag.
The foldable back rest has no locking mechanism. Available in two versions, U3 Light and U3 Light/L, U3 Light has a normal balance and U3 Light/L a more ”tippy” balance. On ”U3 Light/L” the rear axle is moved forward an additional 22 mm. Fine adjustment of the balance is acomplished by adjusting the back rest forward or backwards+-10mm.

SAFETY REGULATIONS

Current information
Up-to-date information on safety and product updates can be found at Panthera’s: website, www.panthera.se
Verify that your wheelchair corresponds with your order:
– Measure the seat width.
– Measure the height of the backrest.
– Ensure you have received the accessories you ordered.
Conduct a technical inspection of your wheelchair, ensuring that:
– the rear wheel’s quick release can easily be shifted in and out of its casings.
– the rear wheel is firmly attached following installation.
– the quick release button springs out fully while in locked position.
– all four wheels are in contact with the floor.
– the castor fork can be rotated with ease.
– the backrest folds down easily.
Balance and tipping capacity
The angle of the backrest, the adjustment of the backrest upholstery and the position of the rear wheel are the most significant factors affecting the wheelchair’s balance and
tendency to tip. After adapting your wheelchair, check that you feel confident about the balance of the wheelchair.
The tipping capacity of the wheelchair may also be affected if a bag is hung on the backrest, if you lean or stretch backwards, if the tyres are worn or contain insufficient air or if there is an unexpected change to the surface you are driving on.
Anti-tip device
Panthera wheelchairs are designed to be as manoeuvrable as possible, which means the wheelchair responds quickly and seamlessly to the actions you perform. If you perform the wrong actions you could tip over in the wheelchair. If you operate the wheelchair incorrectly, there is a risk you may tip backwards.
NOTE! U3 Light has no anti-tip device as an option. The U3 Light is designed for the active, advanced user who can handle a very “tippy” wheelchair and are fully aware that the wheelchair can tip over backwards and adapt their driving according to this.
SAFETY REGULATIONS
Wheelchair skills
It is important to test your wheelchair comprehensively and take the time required to hone your wheelchair skills. If you have any questions on wheelchair technique, contact
the person who prescribed the wheelchair or your therapist. You are also welcome to get in touch with the team at Panthera AB.
Brakes
Your wheelchair is equipped either with brakes for each rear wheel (high brakes) or a one-hand brake. The one-hand brake can be applied by gripping with one hand rather
than two. The brakes are designed as parking brakes and not for braking while in motion.
Please note. In order for the brakes to function correctly, the tyres must contain the correct air pressure. See Technical facts.
The brakes will operate less effectively if the tyres are worn or contain insufficient air pressure. If changing to a different type of tyre, always check the brakes as dimensions may vary.
If you have a high brake, be careful that your fingers do not make contact with the brake when driving with the rear wheel. When transferring sideways in and out of your Panthera, make sure you can lift yourself over the brake so that you do not sit on or get caught on it. If you use the one-hand brake and can stand up, be careful not to open the brake by accident with the back of your legs.
Driving
Before using your wheelchair outdoors, spend plenty of time honing your driving technique in a secure indoor environment with a flat surface.
Always use the anti-tip devices or ensure someone is behind you as you practise. Do not attempt to drive outdoors until you feel completely confident in your wheelchair.
At speeds above 8 km / h the risk of losing control of the wheelchair increases.
Watch out for obstacles such as doorsteps and gutters in which the small castors could become jammed, causing the user to fall forwards.
If the distance between the lowest point of the footrest and the surface is small (less than 40 mm) the footrest could get caught on bumps in the surface and cause you to fall forwards.
If you drive down a curb with the anti-tip devices folded out, they may become jammed and cause you to fall forwards. If you feel unsafe, fold away the anti- tip devices and  ask for help.
The wheelchair can also be fitted with push handles which enable the user to be driven by an assistant.
Shopping or groceries can be hung on the backrest in a bag or rucksack, but you must be fully aware that this substantially increases the risk of the wheelchair tipping back-
wards. In this case, the anti-tip devices must be folded out.
Driving on uneven or inclined surfaces increases the risk of falling both forward and backward.
SAFETY REGULATIONS
Transfer into the wheelchair
Techniques for transfer must be practised extensively together with qualified staff.
The methods described below are for advisory purposes only.
Transferring into the wheelchair sideways (Fig. 4)

1. Position the wheelchair as close to you as possible.
2. Lock the brakes. Se “Brakes” under “Settings”.
3. Place one hand on the far corner of the wheelchair chassis and the other on the surface you are moving from.
4. Carefully transfer yourself into the wheelchair with good balance.
   To ensure the wheelchair is as stable as possible, reverse the wheelchair by 5–10 cm before stopping to make sure the Castors are pointing forwards.

Lifting while the user is in the wheelchair(Fig. 5)
If the wheelchair is to be lifted while the user remains seated, always grip the wheelchair’s chassis. See arrows in Fig. 5.
Do not lift using the backrest, push handles, leg support, wheels or other movable sections.
SAFETY REGULATIONS
Hot surfaces
If the wheelchair is exposed to sunshine for long periods, its surfaces may become extremely warm.
Risk of jamming
While driving the chair, be aware of the risk of your fingers becoming jammed between the rear wheel and the brake, and between the rear wheel and side guard or armrest.
Ensure your fingers or loose items do not become trapped in the rear wheel’s spokes while driving. Moreover, take special care to ensure children do not place their hands
inside the spokes.
Risk of burns
If the wheelchair is equipped with friction pushrims on the drive wheels (see item 7 in Overview), there is a risk of burns to the hands and fingers if you brake the wheelchair
at high speed with the hands of the pushrims, as the friction between the hand and the pushrim generates high heat.
SETTINGS
When adjusting the chair to suit your sitting posture and provide the mobility you require, it is important that you make the adjustments in the correct order.
Firstly, adjust the chair to enable the correct sitting posture. Only then can you adjust the balance of the wheelchair to provide the mobility you require. This must be done in the correct sequence, as adjustments to the sitting posture affect the balance of the wheelchair. Bear in mind that a little effort adjusting the chair to your requirements initially will be of considerable benefit for a long time to come.
Set aside a day to experiment with alternative settings and see how they feel, to ensure the sitting posture and balance of the wheelchair are just right for you.
Adjustments to the wheelchair’s settings must take place in the following order:

1. The tension of the seat upholstery.
2. The height of the footrest.
3. The tension of the calf strap.
4. The angle of the backrest.
5. The tension of the backrest upholstery.
6. The balance of the wheelchair.
7. The brake settings.

SETTINGS

1. The tension of the seat upholstery (Fig. 6)
   The rear section of the seat upholstery can be tightened or loosened by adjusting the Velcro strap underneath.
   This allows you to vary your seat height by around 2 cm upwards or downwards. The seat should be used together with a seat cushion.

2. The height of the footrest (Fig. 7)
   The footrest can be adjusted either upwards or downwards.
   You should adjust the footrest at a height where your thighs are supported by the seat at the same time as your feet are supported by the footplates or foot support.

Adjusting the height of the footrest:

1. Remove the two screws supporting the footrest on the front of the frame using a 3 mm Allen key.
2. You can then move the footrest up or down to fit into one of the fixed positions.
3. Securely tighten the two screws.

Models with Y.front
The footrest in standard configuration allows adjustment in the 4 lowest holes. To use the lowest position (the footrest in its highest position) you need to shorten the footrest with a saw. For more information, please contact Panthera.
3) The tension of the calf strap/heel strap (Fig. 8 and 9)
The tension of the calf strap will determine how far forward you can place your feet on the foot support or footplates, respectively. The suitable tension depends largely on how long or short your legs are.
Adjusting the tension of the calf strap (Fig. 8 and 9)

1. Loosen the calf strap.
2. Place your feet on the foot support/footplates.
3. Adjust the tension of the calf strap using the Velcro strap provided.
   AB reserves the right to make technical changes if required

SETTINGS
4) The angle of the backrest (Fig. 9)

1. Fold the backrest forwards.
2. Loosen the lock screws (1) a few rotations using a 17 mm cap key. Repeat this process on the other side.
3. Adjust the angle of the backrest using the adjustment screws (2) on both sides. Using the 4 mm Allen key, unscrew the adjustment screws to tilt the backrest forwards. Tightening the adjustment screws will allow the backrest to tilt backwards.

It is important to adjust both sides equally to avoid the backrest tubing becoming crooked.
Test this by placing the backrest in the upright position and checking that both adjustment screws are touching the frame.
3) Experiment with suitable backrest angles before tightening the lock nuts (1) on both sides.

5) The tension of the backrest upholstery (Fig. 11)
You can adjust the backrest upholstery to suit the shape of your back using the straps located under the flap at the rear of the backrest. This provides good support to the small of the back.
The backrest upholstery also has a lower flap fastened with Velcro above the seat upholstery, under the seat cushion.
This flap can be moved backwards or forwards to obtain the required tension in the lower section of the back upholstery (known as the seat bucket).

SETTINGS
Adjusting the tension of the backrest upholstery:

1. Lift up the backrest upholstery’s upper flap (1).
2. Loosen the bands.
3.  Sit as far back in the chair as you can. If it feels as though you are not sitting far back enough in the chair, it may be because the backrest upholstery’s lower flap is fastened too far forward on the seat Loosen the flap (2) and then fasten it further back on the seat upholstery.
4. Tighten the bands to ensure you have the necessary support.
5. Fold down the backrest upholstery’s upper flap (1).

The balance of the wheelchair (Fig. 12)
U3 Light has a rigid rear axle and the balance is adjusted by moving the position of the body relative to the rear axle. This is accomplished with moving the backrest into three diferent positions.

The further back you place the backrest the more ”tippy” the wheelchair gets.
This makes the wheelchair light at the front and more of the weight is moved to the reawheels.
The wheelchair becomes more easy to manouver and easier to ”lift up” on the rearwheels, to climb obstacles like curbes, thresholds etc.
The wheelchair must not be to ”tippy”.
Then you risk to tip over and fall backwards. U3 Light comes in two versions, ”U3 Light”, normal balance and ”U2-light
L”, light balance, check that you have recieved the version you have ordered. U3 Light has 75 mm between the rear axle and the rearmost part of the chassis and U2-light
L, has 100 mm, see fig. 2.
Adjusting the balance of the wheelchair (Fig. 11)

1. Remove the rearwheels
2. Loosen the bolt for the backrest clamp (1) from the outside of the chassis with allen key 4 mm, on both side of the wheelchair.
3. Loosen the bolt going through the clamp and the backrest attachment (2).
4. Position the backrest in one of the three holes.
5. Tighten the bolt (2) in the selected hole (2).
6. Tighten the bolt (1) from outside of the chassis.

SETTINGS
7) Adjusting the high brake
Please note! The effectiveness of the brakes is affected when the air pressure drops, the tyres become worn or when changing to a different type of tyre. As a result, the
brakes’ settings should be checked from time to time.
Adjusting high brake (Fig. 12)
High brake are activated by pushing lever (1) forward until stop. The the rear wheel ar locked. Repeat on the other side.

1. Use a 5 mm Allen key in order to loosen the lock screw (1).
2. You will now be able to push the brake forwards and backwards. Adjust the brake so that it presses around 4 mm into the tyre while in locked position. Tighten the lock screw (1) using a 5 mm Allen key.
3. Adjust the brake on the other side by following steps 1 to 3..

Adjusting the one-hand brake (Fig. 13)
One-arm brake is activated by pulling lever (1) backwards until stop. Then both rear wheel are locked at the same time.

1. Use a 4 mm Allen key to loosen the one-hand brake’s clamping bolts on both sides.
2. You will now be able to push the brake forwards and backwards along the chassis’ seat tubing. Adjust the brake so that it presses around 4 mm into the tyre while in locked position.
3.  Ensure that the brakes are in the same forward position on both sides of the chair.
4. Tighten the clamping bolt (1) using a 4 mm Allen key.

ACCESSORIES

Armrests (Fig. 14)
The armrests can be adjusted both horizontally and vertically.
Adjusting the armrest horizontally:

1. Push and hold in the button on the inside of the armrest (1).
2. The armrest can be moved backwards and forwards while the button is pressed in.
3. Release the button at one of the 5 different positions.

Adjusting the armrest vertically:

1. Push and hold in the button on the outside of the armrest (2).
2. The armrest can be moved upwards and downwards while the button is pressed in.
3. Release the button at one of the 4 different positions.
   The armrests can be removed, during transportation, for example, by pulling them up vertically to release them from their
   attachments.. Side guards (Fig. 15)
   The side guards prevent clothing and loose items from becoming jammed in the wheelchair’s spokes and also stop dirt from the wheels getting onto the user’s clothing.

The side guards are fitted with a soft upper section that folds down upon load, for example, when the user transfers to and from the wheelchair.
You can place your hands on the side guards while pulling yourself up and down. The side guards can be removed, during transportation, for example, by pulling them up vertically to release them from their attachments.

Push handles (Fig. 16)
Push handles are used by assistants to drive the user in the wheelchair. The push handles can be adjusted vertically and they can also be folded in.
Folding up the push handle:

1. Lift the push handle uppwards (2).
2. The handle locks automatically in the position.

Folding down the push handle:

1. Push and hold the button on top of the handle (1).
2. Fold down the handle and release the button.

Hip belt (Fig. 17)
A hip belt (positioning belt) may be fitted without affecting conformity to the CE Mark standard.
Hip belts can be fitted around the frame’s tubing at one of the locations indicated in fig 17.

TRANSPORTATION

We would like to emphasise that, when transporting a wheelchair user in a vehicle, it is always preferable to transfer the user to a regular car seat secured by a seat belt.
An exception may be made if the vehicle is fitted with a device designed in accordance with Bus Directive 2001/85/EG, Appendix VII, Item 3.8.3. In such cases, the user may travel without a restraint system with the wheelchair facing in the opposite direction to which the vehicle is travelling.

Assembling and disassembling the wheelchair (Fig. 20 och 21)
When transporting the wheelchair, in a car, for example, the backrest can be folded and the rear wheel detached.
Lowering the backrest, (Fig. 20)

1. Release the side guards and armrests, if necessary, and pull them up vertically.
2. Remove the seat cushion if necessary.
3. Push the backrest forward to lower the backrest.

Detaching the rear wheel, (Fig. 21)

1. Push the quick release button (1).
2. Pull the wheel straight off.

Attaching the rear wheel, (Fig. 21)

1. Push the quick release button (1).
2. Insert the wheel onto the rear axle and then push it in as far as possible.
3. Check that the button has sprung out (1), confirming the quick release is in locked position.
4. Pull the wheel outwards to ensure it is firmly attached.

MAINTENANCE

Your Panthera model was designed for rigorous daily use over a number of years, and as such, some parts must be regularly checked.
If using your wheelchair in more demanding environments, such as sand or saltwater, you must examine and clean your wheelchair more often than what is specified below
Storage
When storing your wheelchair for four months or more, ensure it is kept in a dry, warm area. After storage, check the tyre air pressure and the condition of the upholstery..
Ongoing maintenance
For ongoing maintenance, you will need the following:

• car shampoo or detergent.
• degreasing agent (for removal of severe dirt).
• multi-purpose oil, for example, CRC 5-56

Once a month, you must:

• Wipe the wheelchair chassis over with car shampoo or detergent using a damp cloth. To remove severe dirt, use a degreasing agent. After cleaning, lubricate all movable parts with oil.
• Clean the Castor fork casing (between the wheel and the fork). Hair and dust, etc. often accumulate here which can damage the bearing. Use a 4 mm Allen key in order to loosen the screw. Remove the bolt and detach the Castor. Clean the washers between the wheel and the fork and wipe the outside of the wheel bearing with a cloth. Apply a drop of oil to each bearing. When finished, reassemble the components.
• Lubricate the rear wheel’s quick release. Remove the rear wheel by pressing the quick release button and pulling the wheel straight off. Distribute a few drops of oil over the quick releases at the hub of the rear axle. If you drive in rain, sand, salt or slush, or rarely remove the rear wheel, you should lubricate the quick releases more regularly.
• Pump up the tyres. Unscrew the cap from the tyres’ air valves. Fill the tyres with air at the correct pressure using a suitable valve adaptor (see Technical facts).
• Check that all the screws and nuts are securely fastened. Tighten them where necessary.
• Ensure the wheelchair has not sustained any damage. In the event of damage, immedi ately contact your local supplier or the team at Panthera AB.

Twice a year, you must:

• Lubricate the movable parts of the brakes with a few drops of oil.
• Lubricate the bushing at the joint of the backrest. Use two 10 mm cap keys in order to hold down the bolts and loosen the nuts. Lubricate the bushings with a few drops of oil. When finished, reassemble the components.
• Wash the upholstery when necessary. Machine wash the seat upholstery, backrest upholstery and seat cushion cover at 40°C. Before washing, attach the male velcro to
  female to prevent the upholstery to get rugged by the velcro.

Help with service and repair
For help with service and repair, contact your local supplier first (Assistance centre). You can also contact the team at Panthera AB if you wish.
Instructions for reconditioning can be downloaded at www.panthera.se

Replacement of wear parts (Fig. 25 och 26)
Wear parts such as tyres, inner tubes and Castors can be ordered from Panthera, with the work carried out at home for those able to do so. Otherwise, contact your wheelchair provider or Panthera. www.panthera.se
To replace these yourself, do as follows: Replacing tyres and inner tubes: (Fig. 25)

1. Order parts from Panthera in the correct dimension.
2. Remove the rear wheel by pressing the quick release button and pulling the wheel straight off.
3. Remove the tyre and inner tube using suitable tools. The method is the same as that used for changing the tyre and inner tube on a bicycle wheel.
4. Carefully fit the inner tube and tyre to ensure the inner tube is not punctured. Pump up the tyre.
5. Reattach the wheel to the wheelchair, taking care to ensure the quick release button springs out so the wheel is securely fastened to the hub. Pull the wheel outwards to
   ensure it is firmly attached. Spin the wheel to ensure the tyre has been fitted correctly and the wheel is completely circular.

Replacing Castors: (Fig. 26)

1. Order parts from Panthera in the correct dimension.

2. Detach the Castor using a 4 mm Allen key. Observe how the Castors’ bushings are mounted – there is a right (1) and a left (2) version.

3. When attaching the new Castor, hold down both bushings using your thumb and index finger and then guide the Castor into the fork track.
   At reassembly of castor wheel after cleaning or service you should always check the bolt for thread locking (blue, red or green colour), which indicates sufficient thread locking.
   If the tread locking is missing, always order a new bolt or apply a small amount of weak thread locking.

4. Tighten fully using a 4 mm Allen key. Ensure that the Castor turns easily
