For Preparing, repair and service, the following tools are required: Allen wrench, size: 3 mm, 4 mm, 5 mm and 6 mm Screw wrench, size: 8 mm, 10 mm, 13 mm, 17 mm, 19 mm, 24 mm 6 3 3.1 Safety instructions Meaning of symbols CAUTION! Warning of possible danger of accident and injury. Warning of possible technical damage. INFORMATION! About use of product. INFORMATION! For service-personnel. ATTENTION! Read manual before! 3.2 Common safety instructions Read manual completely before use! Familiarize yourself with handling and functions of the wheelchair before use and practice the handling. You are responsible for the safety of your child. The safety of your child could be affected if you do not follow the instructions of this manual. Nevertheless not all possible circumstances and unpredictable situations can be covered by this manual. Reason, care and circumspection are not features of the product, they are required of persons, who use the wheelchair or attend it. The person, who is using the wheelchair and its accessories should understand all instructions. It must explained to every other person using the wheelchair and its accessories.If instructions are not clear and further explanations become necessary, or if you have further questions please contact your HOGGI dealer. Practise with the new wheelchair on even, straightforward terrain first, together with the child. Together with the child, learn how the wheelchair reacts when the centre of gravity shifts; for example on slopes or inclines or when clearing obstacles such as steps and curbs. This should be done only with assistance from another person. Using an anti-tip is strongly recommended forinexperienced wheelchair users. Strap in your child at all times, when it is in the wheelchair. HOGGI points out, that any use beside the typical use can be dangerous. The wheelchair is not suitable for jogging, running, skating or similar activities. Swivelling front wheels tend to wobble at higher speed, which can cause a sudden stop and tip over of the wheelchair. Use the wheelchair only at regular walking speed. Under no circumstances leave the handle bar while pushing and never push the wheelchair away. The wheelchair should only be used on solid level ground. Use your wheelchair as intended by the manufacturer. For instance, do not drive into obstacles (including steps, curbs) without braking. Do not „jump” the chair down from higher surfaces. To clear obstacles such as steps and curbs, tilt the wheelchair onto the rear wheels (pull it backwards to go up; to descend, slowly lower it forward). If only one attendant is available when ascending or descending stairs, an incorrectly set anti-tip (if mounted at all) can lead to severe falls. Adjust the anti-tipper so that it does not come in the way of the steps during transport. Afterwards, swing the anti-tipper back to its operational position. 7 Do not go up or down stairs without the assistance of another person. If devices such as ramps or elevators are available, please use them. Ensure that the anti-tip (if mounted) is outside the danger-area. If wheelchairfriendly access is missing, two attendants must carry the wheelchair over the obstacle. The wheelchair should be lifted only by touching tighten parts of the frame (on the side frame above the front wheels and on the push handles which are fixed on the backrest base - if brakes are closed, also the push-rims can be used for lifting). When ascending slopes or ramps and when crossing obstacles on upward slopes, always lean the wheelchair user‘s upper body far forward. When descending slopes, do not drive without braking and reduce your speed. Reduced load on the casters due to centre of gravity shifting can cause the casters to flutter. If you have to park on a slope, face the wheelchair uphill with the brakes engaged and ensure that the seat is in the upright position. There is a risk that the pushchair might tip over backwards if the seat is the reclined position. Before leaving the wheelchair and before getting into and out of it, always lock the wheel locks. - Don´t use the footrest to get into and out of the wheelchair generally. - Use the footrest with shoes only. Depending on footplate settings and wheelchair geometry, the wheelchair may tip over if the user boards the chair using the footplate. First practise boarding the chair with the child and an attendant who can secure the wheelchair, and modify footplate and seat height settings if the chair has a tendency to tip over. In addition, turn the caster fork to the front prior to using the footplate for getting into the wheelchair; this increases the wheelbase and thereby the wheelchair‘s stability against tipping. The effectiveness of the wheel lock and the overall driving quality are dependent on adequate air pressure. With properly inflated rear wheels and even tyre pressure on both sides, your wheelchair is much easier to operate and manoeuvre. Before starting to use your wheelchair, check that the tyres are inflated correctly. The required air pressure is printed on the side of the tyre. For rear wheels, it should be at least 6 bar. All brakes acting on the tyres do not serve as service brake but are only designed as parking brake (wheel lock). The wheel locks must not be used as driving brakes for slowing down the wheelchair, as in extreme cases, the abrupt stopping of the wheelchair can lead to falls. Please keep packaging material away from children. Plastic packaging presents the danger of suffocation. Disposal of waste: The packaging material as far as metal, aluminium and plastic parts can be recycled. The recycling must be operated according to the national and legal terms. Check the condition of the product if the packaging shows damages. Never leave your child unattended in the wheelchair even when they are strapped in and the brakes engaged. In the dark, the user should wear light clothing or clothing with reflectors in order to improve visibility. Ensure that the reflectors are installed on the sides and rear of the wheelchair. 8 Extreme settings (e.g. shortest wheelbase and seat in the backmost position) combined with an unfavourable body posture can cause the wheelchair to tip even on level ground. Static stability is >10° inclination. Attaching heavy bags or other weight to the push-handles can adversely affect stability. Adjustments with a high active degree demand a practised driver and the use of an anti-tip. Under no conditions should the anti-tip(s) assume the function of transport wheels, for example to transport a person in the wheelchair with the rear wheels removed. The antitips must audibly lock in place, before it is able to bear loads. Firm seating must be verified by the user or by an attendant. The maximum load for the SHERPA is 134 kg. Accessories and add-ons reduce the maximum load proportionately. We recommend that, wherever and whenever possible, users transfer to the seats installed in the motor vehicle and use the corresponding vehicle restraint systems, because this is the only way to ensure optimum protection of the passengers in case of an accident. SHERPA is not admitted for use as a seat in a motor vehicle. Always make sure that the quick-release axles are correctly set on the rear wheel. It may not be possible to remove the rear wheel unless the button on the quick-release axle is pushed. Neither seat nor backrest height may be exceeded. The assembly of a seat shell is only permitted within the specified seating area. The manufacturer of that new product combination has to test the stability and the adherence of the maximum load before commissioning. When applying seat and backrest panels always use upholstered seat cushions to avoid to avoid dents. Avoid reaching into any clamping range. Danger of clamping exist in following assembly groups: - Brake lever (if SHERPA is supplied with fender with integrated brake system) - Between brake lever and rear wheel The wheelchair should be lifted only by touching tighten parts of the frame (on the side frame above the front wheels and on the push handles which are fixed on the backrest base - if brakes are closed, also the push-rims can be used for lifting). The HOGGI seat cushion (Trevira CS) and the contoured seat cushion (Trevira CS) as well as the HOGGI nylon backrest abd seat cover are flame resistant referred to the EN 1021-1 and EN 1021-2 norm. If using different seat or backrest cushions to the original HOGGI upholstery the flame-retarding impact is not a given. 9 Be careful in case of extreme temperatures. The wheelchair can heat up significantly when in the sun or in the sauna. In extreme cold, there is a risk of hypothermia. Slowing down from high speeds or when descending longer slopes tends to heat up the hands and fingers, especially if using aluminium push rings. When using the wheelchair outdoors, leather gloves should be worn. Gloves provide the wheelchair user with a better grip and protect his or her fingers from dirt and hot metal. Persons with a insensitive skin (people which cannot sense an increase of temperature) and/or with skin harms have to pay attention, that metal parts will not get too hot. In these cases it is mandatory to wear appropriate clothes to protect the skin. Please read to visually handicapped people the manual and info material - or use electric aids. Please download or read all SHERPA documents on our website www.hoggi.de. Whenever you change any settings on the wheelchair, make sure that you firmly tighten any screws that have been loosened. 10 4 Delivery and preparing for use Your SHERPA system-wheelchair will normally be supplied completely mounted with folded backrest and with removed rear wheels.

The required air pressure is printed on the side of the tires. • To release the wheel lock pull the brake lever to the back 5.2 Seat width / Seat height / Camber SHERPA is available in the seat widths from 320 up to 480 mm. The seat width gets measured between the wheel guards and it depends on the cross tubes. The SHERPA system-wheelchair will be built in accordance with the customer’s order. It is possible for the technician to modify the wheelchair with a different seat width. The Seat height depends on the size of rear and front wheels. The SHERPA system-wheelchair will be built in accordance with the customer’s order. It is possible for the technician to modify the wheelchair with a different seat height. The SHERPA can be supplied with rear wheels inclined (camber) 0° (as pictured) or 3°. A camber of 3° is only available for rear wheels with 22“ and 24“. The SHERPA system-wheelchair will be built in accordance with the customer’s order. It is possible for the technician to modify the wheelchair with a different camber. 5.3 Seat depth Loosen the two marked screw connections lateral of the seating panel (on both sides) and adjust the seat depth by sliding the backrest panel. Remove the seat cushion first. The seat depth (min/max) is restricted by 2 stops - see arrows. 20 Whenever you change any settings on the wheelchair, make sure that you firmly tighten any screws that have been loosened. 14 5.4 Backrest height (backrest panel trough shaped) If your SHERPA system-wheelchair is supplied with a trough shaped, 2-parts, height adjustable backrest, please proceed as follows: Loosen the six screws on the backrest panel and adjust the backrest height by sliding the panel to the required position.

CAUTION! Danger for movable parts. Avoid reaching into any clamping range. 5.6 Active degree The active degree describes the relation of the backrest position to the rear wheels. The more the backrest is positioned to the rear of the axle, the more active the SHERPA can be driven (e.g. lifting of the front wheels). That means contrary a safer driving position if the adjustment is set above or in front of the rear axle. CAUTION! Adjustments with a high active degree demand a practised driver and the use of an anti-tip. The SHERPA will be built in accordance with the customer’s order. It is possible for the dealer to modify the active degree. • Loosen both marked screw connections (as shown) on both sides of the SHERPA and slide the seat unit in the required position. The active degree is restricted by 2 stops - see arrows. Whenever you change any settings on the wheelchair, make sure that you firmly tighten any screws that have been loosened. 5.7 Tilt in space • Lock both wheel locks. • Pull the release handle until the locking mechanism is fully disengaged. By using the push-bar or push-handles, the seat unit can be adjusted to any angle between -7° and +45°. Set the required seat angle and allow the bolt to lock in the required position. 15 CAUTION! Push sharply on the push-bar or push-handle to ensure that the bolt is securely located. CAUTION! Danger for movable parts. Avoid reaching into any clamping range.

CAUTION! Danger of clamping whilst folding. Avoid reaching into any clamping range. For convenience of handling it may be preferable to partially dismantle the system-wheelchair into a few main components. To achieve the most compact folding package fold the backrest and the footrest but remove the rear wheels, the anti-tip assemblies and the push-bar/ push-handles The system-wheelchair should be lifted only by touching tighten parts of the frame (on the side frame above the front wheels). If brakes are closed, also the push-rims can be used for lifting. 7.2 Using SHERPA for bus transport CAUTION! We recommend that, wherever and whenever possible, users transfer to the seats installed in the motor vehicle and use the corresponding vehicle restraint systems, because this is the only way to ensure optimum protection of the passengers in case of an accident. SHERPA is admitted for use as a seat in a motor vehicle according to ISO 7176-19 and ANSI / RESNA WC-4 Section 19. 7.3 General • Check that your wheelchair is suitable for a crash test. • Check that the vehicle is equipped and compatible for transporting your wheelchair. • Pay attention to the correct course of the belt (see marking) • There should also be enough space for safe transport. • During transport ensure an upright sitting position. 21 7.4 Securing the wheelchair during bus transport We recommend that, wherever and whenever possible users transfer to the seats installed in the motor vehicle and use the corresponding vehicle restraint systems, because this is the only way to ensure optimum protection of the passengers in case of an accident. SHERPA was successfully tested in accordance with ISO 7176-19 (Crash Test). It is, however, possible to use SHERPA as a seat in a motor vehicle, if our “Tie down Kit” as well as appropriate restraint systems are used. Your SHERPA is admitted for use as a seat in a motor vehicle yet. 1) If the user finds itself in the rehab pushchair, the rehab pushchair has to be positioned forward and has to be fixed with the fastening and safety belts according to the instruction for use of the restraint system manufacturer (fastening belts referred to WTORS need to fulfil the requirements of ISO 10542 or SAE J2249). 2) The wheelchair has not been tested for transportation in another position. The transportation in a lateral directed position for instance is not allowed at all. 3) Depending on the size of the pushchair the maneuverability can be impaired, so that the turning of the pushchair is not or only partially possible,to position the stroller forward in the direction of travel. 4) The buggy has to be fixed with a restraint system referred to ISO 10542 or SAE J2249 with fixed belts in the front and adjustable belts in the back. Usually this concerns snap hooks/ s-shaped hooks as well as plug closures. The restraint systems usually consist of 4 single belts, which have to be attached to the 4 edges of the pushchair. The attachment points of the pushchair restraint systems are marked with the international hook symbol. 5) The wheelchair may also be supplemented for transport with other positioning and fixation systems. However, these are not a substitute for passenger and rehab pushchair restraint systems and may limit user comfort. The accommodation of a wheelchair in a vehicle using anchored belts was rated as „poor“ according to the test methods of ISO 7176-19 Appendix D. SHERPA may only be used forward in the direction of travel. The wheelchair was dynamically tested in the direction of travel and the dummy was there fastened with lap belt and shoulder strap. In order to reduce the risk of injury to vehicle occupants, tools that are not specifically designed for crash safety, should be removed and stored separately in the vehicle safely such. eg crutches, loose pillows, therapy tables etc. Without consulting the manufacturer, no changes may be made or replaced at the points of attachment of the wheelchair or to components of the chassis and frame. Failure to comply with these requirements, the wheelchair may not be transported in vehicles.. 22 7.5 Buckling the wheelchair passenger The user has to be buckled up with the lap belt as well as the shoulder belt. Shoulder and lap belts should be used to minimize and / or avoid potential injury from impact on vehicle components. 1) The person executing the attachment should be trained in the handling of the system. 2) Before transportation the following adjustments of the rehab buggy have to be carried out: Seat: 0° - 5° Backrest: 90° - 100° Footrest: 90° 3) The angle between lap belt and horizontal has to be 30°- 75°. An angle close to 75° is preferable. 23 4) The shoulder belt has to run across to chest and shoulder. The belt may not but at the neck and may not be attached loose from the shoulder. The lap belt and the shoulder belt must be flat and as tight as possible against the body and must not be damaged by components such as e.g. Armrests or wheels are kept away from the body and must not restrict user comfort. 5) The belt strap may not be twisted. As far as possible all additives should be detached and stored securely: • crutches, loose cushions and therapy trays. 6) The user‘s head should be additionally secured by a separate and permanently mounted headrest in the bus. You should not rely on the occupant restraint systems unless they are marked in accordance with the requirements of ISO 7176-19: 2008. 7) During transport, the drum brake must not be tightened. 8) Please lock the manual brake firmly. Care should be taken that the occupant restraint is positioned so that in the event of an accident, the release button is not triggered by pushchair components and results in unintentional opening of the seat belts. 9) Remember, however: In the event of a traffic accident, the risk of injury can only be minimized and not ruled out, even if the passenger and rehab pushchair restraint systems are used correctly. Before reusing the pushchair after a collision or an accident with a bus, the pushchair may no longer be used for transport in a bus until it has been checked for possible damage by authorized personnel and then released again. If you have questions about our products and transport safety devices for wheelchairs, we or your specialist dealer will be happy to help. Attachment points, front according to ISO 7176-19 Attachment points, rear according to ISO 7176-19 for lap belt 24 Attachment points, rear according to ISO 7176-19 7.6 Transfer - getting into or out of SHERPA CAUTION! • Always lock the wheel locks before getting into or out of the wheelchair. • First practise boarding the chair with the child and and an attendant who can secure the wheelchair, and modify the footplate and the seat height settings if the chair has a tendency to tip over. • Raise the tilt resistance by turning steering fork to the front (wheelbase will be enlarged). For adolescents it can be advantageous, according to age, weight and ability, to make a transfer over the side of the wheelchair. • Firstly position the wheelchair at an angle of 45° to the seat or wheelchair, from which a transfer is to be made. • Apply the knee lever brakes. During the transfer the seat surface, the backrest surface, the push rims or briefly the side of the seat can be used for support. The transfer should be practiced with a helper, until it can be accomplished safely. The transfer should be carried out in one movement. • Afterwards, fold down the foot rest and position the feet on it. If necessarycorrect the seat position. Finally the parking brake can be released and the wheelchair is ready for use. • Carry out the sequence in reverse when getting out of the wheechair. 7.5 Anti-tippers to override steps The SHERPA is equipped with two anti-tip units. The antitip increases the stability of the system-wheelchair. Function and attachment of the footrest lock are described in „4 Delivery and preparing for use“ and „5.9. Anti-tip“. CAUTION! If the overriding of steps are only with the help of another person possible - a mounted or active anti-tip can lead to falls. Adjust the anti-tip so that it can not touch the steps. After overriding the steps or similar barriers adjust the anti-tip again. 25 8 Storage The SHERPA can according to size and specification, be transported as one unit, with folded down backrest and folded up footrest. Instructions for cleaning and maintenance Clean your SHERPA systematicly before storage. Follow the instructions for cleaning and maintenance thereby on page 24. For convenience of handling it may be preferable to partially dismantle the system-wheelchair into a few main components. To achieve the most compact folding package fold the backrest and the footrest but remove the rear wheels, the anti-tip assemblies and the push-bar/ push-handles. 9 Maintenance Your SHERPA is CE approved. The manufacturer herewith guarantees that this medical product as a whole conforms to the basic safety and performance requirements in accordance with Annex I to Regulation (EU) 2017/745 of the EU Parliament and of the Council. The wheelchair should be checked for correct function before every use. Nuts with self-assurance should only be used once. After repeated loosening nuts must be replaced. The items listed in the following table must be checked by the user at the indicated intervals. Check daily before use Function test of the brake/wheel lock X Function test of the anti-tip X Function of rear wheels quick-release system X weekly Check stability of footrest X Air pressure (see indication on tyre) X Push rims for damage X monthly Screw connections X Visual inspection for worn parts (e.g. tyres, bearings) X Dirt on bearings X Spoke tension of the rear wheels X Function test of the tilt mechanism X Should any defects become obvious, please contact your authorized HOGGI dealer to eliminate them.

We recommend an annual inspeciton by an authorized HOGGI dealer. In case of an interference or a damage of the wheelchair it has to be checked immediately by a dealer or a medical supply store. Instructions for cleaning and maintenance - Clean all frame components and plastic parts using mild detergents only. (e.g. Sagrotan) - Padding parts can be washed at 40 °C. If washed in a washing machine, put them in a linen bag or a pillow case - In most cases, wiping with a damp cloth is sufficient. - Do not use your SHERPA wheelchair in salt water. - Keep sand or other particles from damaging the wheel bearings. - If your wheelchair gets wet, towel-dry it as soon as possible. - Hair and dirt particles generally accumulate between the caster wheel and fork. This can restrict the caster wheels from rotating smoothly. Remove the caster and thoroughly clean the fork and caster using a mild detergent. - The rear wheels feature a quick-release system. To keep this system operational, ensure that no dirt adheres to the quick-release axle or axle housing. The quickrelease axle should also be lightly lubricated regularly with resin-free sewing machine oil. - Screw connections should be checked frequently, in particular when beginning to use the wheelchair and after any adjustment. If a screw connection becomes loose repeatedly, consult your dealer. 10 Recycling and disposal SHERPA is manufactured from recyclable material. The packaging material as far as metal, aluminium and plastic parts can be recycled.
