Safety warnings
Safety warnings
Safety is a very important with any vehicle that is power driven, here are some helpful tips to safeguard your use.
General
Always ensure that your wheelchair is switched off before attempting to mount or dismount.
Always ensure that you are able to operate all controls from a comfortable position. Paying attention to your posture is essential to ensure your continued comfort and well being.
Always make sure that you can be seen clearly, especially if you intend using your wheelchair in poor light.
Kerbs
Never descend a kerb forwards. Please read carefully the section on kerb climbing in this manual before attempting to mount and dismount any kerbs in your wheelchair.
Do not attempt to climb or dismount a series of steps. It is unsafe to do so and could cause personal injury or damage the chair. The F50 has only been designed to climb a single step or kerb.
Routine service
Like most things in life a little care and attention goes a long way and your chair is no exception. The recommended service interval is one year. (See service history on later page).
Emergency freewheel
Please remember that you have no braking facility when the freewheel lever is moved from the normal drive position to the freewheel position.
The wheelchair must never be left with the lever in the freewheel position. For a fuller description of this facility and its limitations to use please see later section.
Emergency braking
The simplest and safest way to stop the wheelchair is to release the joystick control lever (see Control pod section). This will bring the chair to halt in a controlled manner.
Switching the control system off whilst the chair is in motion will also bring the chair to a halt. This latter method is not recommended as the stopping action is very abrupt.
Sharp turns
Full speed turns should not be attempted. If you need to turn sharply you must reduce your speed with the joystick or speed setting. This is particularly important when travelling across or down a slope. Disregarding this advice could lead to your wheelchair tipping over.
Issue 4 4
Safety warnings
Batteries
Your wheelchair is supplied as standard from Sunrise Medical with maintenance-free batteries. These only require regular charging.
Do not, under any circumstances, tamper with the batteries. If in any doubt contact your local service agent.
Do not connect the battery charger to the mains supply until after you have connected the charger to the wheelchair. Before charging, please read the relevant section in this manual. Take care with battery acid which is very dangerous. It can cause burns to the skin as well as damage to floors, furniture and your wheelchair. If it comes into contact with the skin or clothing, wash immediately with soap and water. If it comes into contact with the eye, immediately flood the eye with running cold water for at least 10 minutes and seek medical attention immediately. Acid can be neutralised with baking soda and water. Take care to keep batteries upright at all times, especially when transporting your wheelchair.
Tyres
Your wheelchair tyres can wear depending on use. Check them regularly in accordance with the service instructions in this manual, especially the pressure of the tyres.
NEVER inflate the tyres using a garage forecourt airline, always use the pump provided.
Cleaning seating
Should the seating of your wheelchair become soiled or dirty, it can be wiped with a damp cloth with a dilute disinfectant until clean. This is important should the wheelchair be used by more than one person to ensure there is no cross infection.
Cleaning controls
Should the control of your wheelchair become soiled or dirty, it can be wiped with a damp cloth with a dilute disinfectant until clean. This is important should the wheelchair be used by more than one person to ensure there is no cross infection.
Note: Before using your vehicle for the first time, please charge your batteries for a period of 24 hours.
Wheelchair motors
After prolonged use, the motors will produce heat which is radiated through the motors outer casing. Do not touch the motors outer casing for at least 30 minutes after using the wheelchair, to allow it to cool.
5 Issue 4
Safety warnings
Wheelchair range
The range of your wheelchair can be affected by many factors such as user weight, terrain, ambient temperature and battery condition. The stated range in the sales literature should be seen as the theoretical maximum and may not be attained by every user.
We recommend that every user initially limit their journey to half the stated range, until they have confidence in the actual range their wheelchair can attain. If your battery indicator is showing a low charge then do not attempt a long journey unless you are confident in reaching your destination and also returning to your home without the risk of being left stranded.
Use on a slope (continued)
Failure to do this may cause the wheelchair to become unstable.
If you are in any doubt about the capabilities of wheelchair on a slope then do not attempt to drive up or down the slope, try to find an alternative route.
Mobile telephones and two ­way radios.
When operating cordless or mobile telephones, two way radios, walkie­talkies, C.B. Amateur Radio or other transmitting devices, the following must be noted:
Mobile telephones or two - way radios devices must not be used while operating the vehicle.
Use on a slope
Your wheelchair has been designed and tested to allow its use on slopes or gradients of up to 8° or 10°. However, if you have the option of adjusting the angle of seating with either tilt seat or recline back, then in certain circumstances your wheelchair could become unstable. Before attempting to climb or decline a slope, we strongly recommend that you return the seat and back to an upright position.
Use of Mobile Phones or Two Way Radios can cause excessively strong electromagnetic fields. This may interfere with the vehicles electronic systems. If Mobile Phones or Two Way Radios are required to be used, the vehicle must be brought to a halt and the power turned off before any such device is switched on or used.

Preparing your wheelchair for use
Power-base assembly
Your Sunrise electric wheelchair has been designed with a unique capability - the front and rear sections of the powerbase will separate, allowing for greater ease when transporting your chair (Fig.1). To “re-dock” the two halves tilt the rear unit backwards resting unit on the small anti-tip wheels (Fig.1). Ensure that the drive lever is engaged, this will prevent the power base from moving. Offer the front sub frame studs “A” (Fig.1a) to the lower slots in the rear sub frame brackets and locate. The two halves now form an arch, push the front of the rear unit down (Fig.1b) to couple both units together. Secure the coupling by locking over the seat location bar to engage studs “B” (Fig.1c).
Location stud “A”
Fig. 1A
Fig. 1B
Push Down
If the above procedures have been performed correctly, the front and rear sections of the wheelchair should now be completely secure. Test by lifting the seat location bar (Fig.1a) without any downward movement, which would cause the two section to part (Fig.1c). If the chair is correctly ‘Docked’, the pins will remain firmly in their slots. Re­dock if not.
The term “de-dock” is used to describe the separation of the front and rear sub frames. To de-dock push seat location bar towards front sub frame and lift in one movement.

Preparing your wheelchair for use
Fitting the batteries
Your Sunrise wheelchair batteries are located in two battery boxes. With your powerbase fully assembled, drop the battery boxes into the centre of the powerbase. It is important to note that there is a left and a right hand battery box. The easiest way to remember which battery box locates where, is to ensure that the curved side panel of each battery box forms a natural wheel arch to the rear wheels.
Locate securely, the battery boxes and lid clips. Take the leads from each battery box and connect together.
Connect battery socket on Battery loom to socket on loom coming out of rear chassis moulding.

Seat stem adjustment
In order to provide fine adjustment of the angle of the seat frame, you will note that the seat stem is fitted with a locknut where the seat stem meets the under seat cross bar. To adjust the seat angle to a position between that normally provided for by the series of holes in the seat stem. To increase the angle turn the stem anti-clock wise, to decrease turn stem clockwise.The holes in the seat must always be aligned so that the locking pin is always free to engage with the desired hole in the seat stem. Once the adjustment has been made and with the knob correctly engaged with the appropriate seat stem hole, the locknut must then be fully retightened.
Locknut
12mm (1/2”) Max
Fig. 7
The adjustment provided by the above means, is intended for adjustment between hole spacings only. The gap between the top of the seat stem and locknut must not exceed 12mm (1/2”) (Fig. 7).
If in doubt consult Sunrise Medical or your local dealer.
Always check to see if the seat stem locking mechanism has properly located into the seat stem hole by exerting downward pressure with your palm on the seat itself.
Issue 4 10
Preparing your wheelchair for use
Never attempt to adjust the seat angle with the user still occupying the chair. Never attempt to drive the wheelchair with set angle in excess of 15° from horizontal.
Removal of seat frame
To remove the seat frame press down the finger bar and pull backwards to release the seat stem and lift the seat upwards until it can be raised no further. With the tip of the seat stem resting in it’s receiving hole, pull the whole seat gently towards you (lifting at the same time) until the seat is clear of the powerbase.
Armrests/skirt guard
To fit the armrest/skirt guard assembly, ensure that locking pin (A) (Fig. 9) is in the ‘unlocked’ position shown. Lower the armrest into the support cups and press down to ensure a firm location. Release the locking pin lever to lock position. To adjust the height of the armrest pull back the lever of locking pin (B) and hold. Lift or lower armrest to the required position and release pin to lock position, check armrest has seated properly.
Adjustment bolts
Seat pan height adjustment
In addition to being able to adjust the single angle of the seat pan to the power base by selection of the appropriate hole in the seat stem, the height of the complete seat pan can be adjusted to suit the chair user (Fig. 8). The chair will normally be supplied with the seat pan at its lowest setting. To raise the rear of the seat pan, remove two nuts and bolts at either end of the seat location bar. The seat location bar may now be raised to the desired level and bolts reinserted.
Having raised the seat location bar, it will be necessary to select a higher position with the seat stem.

See section on charging.
Operation the control joystick
When engaging the main On/Off switch, allow a few seconds prior to moving the joystick. This allows the system to self check. If you move the joystick too soon, the battery level indicator display will flash, disabling drive to your wheelchair. Whilst this is not harmful to your wheelchair, you will need to switch off and then back on to clear the system.
To steer, simply move the joystick in the direction you wish to go. Proceed slowly at first, i.e. do not push the joystick too far forward.
Note: If you need to stop in an emergency, the simplest and safest way is to just release the joystick. This will being the chair to halt in a controlled manner.
A second means of bringing the chair to a halt is to press the On/Off switch. This method is not recommended as the chair will stop very abruptly and will cause unnecessary wear in the chairs braking system.
Brakes will operate as soon as the joystick is released and allowed to return to its centre position. On level ground, this should bring you to a halt within one chair’s length (6 km/h model). On a steep hill, it may travel slightly further and you will notice the brakes being automatically applied when the chair is nearly stationary. Once the brakes have been applied, switching off will make no difference to the brakes, although it is always safer when remaining stationary for a period of time to switch off.

Summary
1. To steer, simply move the joystick in the direction you wish to go (Fig. 22).
2. The further you move the joystick, the faster you will go.
3. New users should use slower speeds until they are confident when driving the power chair. Adjust the speed range as explained on the previous pages.
4. The brakes will automatically stop the wheelchair from any speed when the joystick is released.
5. Switching off immediately applies braking and is not recommended for normal use.
6. It is important that the chair is stationary when changing direction from reverse to forward.
7. Always switch to off before getting into or out of the chair.

Parallel Swing-Away Arm
Before adjusting the swing­away arm, switch off the controller to avoid accidental displacement of the joystick which would cause unwanted movement of your wheelchair.
Gently apply pressure to the side of the controller nearest the user and as close as possible to the front of the controller.
The controller will move outward and then backward before reaching its fully back position.
Keep your fingers and clothing, etc., clear while operating the swing-away mechanism.
If required, your wheelchair can be operated with the swing-away mechanism in its fully back position, but only for slow manoeuvering such as positioning the wheelchair closer to table tops, etc.
To revert to the normal driving position, switch off the power and pull the arm outwards and then forwards before returning the arm to its ‘home’ position. Make sure the controller is fully engaged in its home position before switching on and operating the wheelchair in the normal manner.
Caution Do not hang any items on or over
the parallel swing-away remote assembly as this could damage the swing-away mechanism.
When transferring to and from the wheelchair do not use the remote as a means of support.
Fig. 23
Warning Keep fingers, clothing, etc., clear
of the swing-away mechanism at all times.
Ensure the power is switched off while adjusting the parallel swing-away arm.
Only operate the wheelchair at low manoeuvring speed when the parallel swing-away is in use.

Using your wheelchair
Kerb climber
Fitting
Offer the kerb climber up to the ”U” brackets, align holes in the kerb climber shaft with the alignment holes in the “U” brackets. Take the spring clips and feed the straight section into the “U” bracket alignment holes. Push in until the shaped section of the clip grips the outer surface of the “U” bracket (Fig. 24).
“U”brackets
Spring clips
Mounting the kerb
1 Approach the kerb head on
driving forwards slowly and steadily.
2 As the Kerb Climber makes
contact with the kerb, the wheelchair should be moving slowly. Small kerbs can be climbed from a standstill.
3 Apply sufficient power to the
motors to lift the front of the chair up onto the kerb and then apply slightly more power and speed so that the drive wheels climb the kerb smoothly and without hesitation. As far as possible, keep the joystick in the straight forward position.
Fig. 24
Dismounting the kerb
1 Reverse the chair slowly and
carefully until the rear wheels are on the edge of the kerb.
2 Reverse as slowly as possible off
the kerb with the rear wheels. You will feel more secure if you can lean forward, but if you can’t, don’t worry, the wheelchair is extremely stable and as long as you stay within its limitation you will be quite safe.
3 The front of the chair will
naturally follow down the kerb as you continue to drive slowly backwards.
21 Issue 4
Using your wheelchair
Kerb climber (Caution)
1 Please show the utmost
consideration for the other traffic on the road. Remember that the last thing a car or lorry driver expects to see is a wheelchair backing off the kerb into the road. If in any doubt, do not risk crossing the road until you are certain that it is safe.
2 Always cross the road as quickly
as possible, there may be other traffic.
3 Do not attempt to go up or down
more than a 10cm (4”) high kerb.
4 Do not attempt to use the kerb
climber on a series of steps.
5 Do not attempt high kerbs if on
steep slopes or cambers.
It is not intended for permanent use.
REMEMBER: The chairs automatic braking system will not work unless the handle on the right hand side of the chair is pushed down.
ALWAYS RE-ENGAGE THE EMERGENCY FREEWHEEL AFTER USE
IN FREEWHEEL NEVER leave or
attempt to enter/dismount the chair.
Remember that the wheelchair is heavy and you may not be able to stop the wheelchair from rolling away if you engage the freewheel on sloping ground.
6 Do not attempt any kerbs in the
vicinity of drain covers, uneven or gritty road surfaces.
7 Do not attempt to dismount a
kerb any higher than 5cm (2”) in the forwards direction.
8 Do not mount or dismount kerbs
at an angle other than straight on (90 degrees) to the edge of the kerb.
9 Prior to climbing ensure your
legrests will clear the kerb.
Emergency freewheel
This is a mechanism which enables the drive to be disconnected in the event of battery or other failure. This may only be used in an emergency, or if you need to manually push your wheelchair (Fig. 25).

Batteries and charging
General information
Batteries are the power source for almost all of the modern mobility products available today. The design of batteries used in mobility products is significantly different to the batteries used to start a car for example. Car batteries are designed to release a large amount of power over a short period of time, whilst mobility batteries (commonly called deep cycle batteries) release their power evenly, over a long period of time. Therefore, due to the lower production volumes and increased technological requirements, mobility batteries are typically more expensive.
Commonly two 12 volt batteries are used together in a mobility product, giving a total voltage of 24 volts. The size of the battery, (e.g. its available power) is expressed in amps per hour e.g. 30amp/hr. The higher the number, the bigger the battery size, weight and, potentially, the greater the distance you can travel.
Maintenance free batteries
This type of battery uses a method of carrying the electrolyte commonly referred to as ‘gel’, that is held within the battery case. As the name implies, no maintenance is required other than regular charging. You can safely transport this type of battery without fear of acid spilling.
Furthermore, they are approved for transportation on aircraft.
Battery care
Below is set out a battery care plan for maintenance free batteries. This has been agreed between Sunrise Medical and the battery manufacturers, to enable you to get the best out of your batteries. If a different care plan is followed, this may result in lower than expected performance from your mobility vehicle.
Sunrise Medical only fit as standard maintenance free batteries into this type of wheelchair.

Medical charger compatible with the vehicle to be charged.
2 Charge your batteries every
night, regardless of the amount of use your mobility device has had during the day.
3 Do not interrupt the charging
cycle.
4 If your mobility device is not
required for use, it should remain connected to the charger until required. This will not damage your batteries, so long as the mains socket/plug is left switched on. Turning the mains socket/plug off, but leaving the mains cable plugged in will eventually deplete your battery charge.
5 If you leave your vehicle for an
extended period (more than 5 days) disconnect the main battery lead.
9 The battery terminals need to be
checked regularly for signs of corrosion. If any corrosion is apparent, then clean the terminals completely (a wire brush is ideal) and re-grease the terminal using Vaseline petroleum jelly, not ordinary grease. Ensure that the terminal nut and bolt, cable clip and exposed cable are completely covered with jelly.
10Following all the points above
should result in a healthier battery, greater range for the vehicle user and a longer life for your batteries.
Do not expose any part of the battery to direct heat (i.e. naked flame, gas fire).
When charging always place on a hard surface in a room with good ventilation.
You should not charge your batteries in outdoor conditions
6 Failure to allow for recharge will
damage the batteries and can lead to shortened distances and premature failure.
7 Do not top up the charge of your
batteries during the day. Wait until the evening for a full overnight charge.
8 As a general rule, maintenance
free batteries take longer to fully charge than lead acid batteries.

Batteries and charging
General
The external charger (Fig. 26) has been designed to charge two 12 volt Sonnenschien Dryfit Gel type batteries.
Safety features
The chargers have features which prevent hazards or accidents occurring as a result of connecting batteries the wrong way round, overheating caused by fault conditions, or attempting to charge wrong voltage batteries.
On/Off switch on rear case
The majority of charger sizes are electrically double insulated and no earth connection is required. Some larger sizes may be electrically earthed and this will be clearly stated on the label.
The 3 pin UK mains input plug contains a replaceable fuse. The rating of this fuse is shown on the charger label. Always replace with the same type and size of fuse as specified. Fitting of different fuses can result in damage to the charger or failure of the charger to operate properly.
If your charger has been specified for use in Continental Europe it will contain a European two pin plug which does not have a fuse. In this case the fuse is located in the fascia panel of the charger.

Safety and caution notes
1 The charger is designed for
indoor use. Do not use outdoors or expose to rain, snow, spray or moisture.
2 Use only with Sonnenschein
dryfit Gel type batteries of the A200, A500 or A500C groups when employed in cyclic mode.
3 The charger may be used with
other brands of Gel type batteries, subject to written confirmation from the Technical Department of Sunrise Medical.
4 Do not smoke, or create sparks
or flames in the vicinity of the batteries.
5 Avoid standing the charger on
carpets or rugs during use and do not cover the ventilation slots of the charger or allow objects to rest on the case.
6 Do not attempt to recharge other
types of batteries such as car batteries, non-rechargeable batteries, AGM sealed batteries, wet electrolyte batteries or batteries of the wrong voltage.
9 Use of an attachment, not
recommended or sold by Sunrise Medical, may result in a risk of fire, electric shock or injury to persons. To reduce the risk of damage to electric plug and cord, pull by the plug rather than the cord when disconnecting the charger. Make sure the cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress. An extension cord should not be used unless absolutely necessary. Use of an improper extension cord could result in a risk of fire and electric shock. If any extension cord must be used, make sure the pins on the plug of the extension cord are the same number, size and shape as those of the plug on the charger; and that the extension cord is properly wired and in good electrical condition.
7 Repairs should only be carried
out by Sunrise Medical.
8 The charger is designed for
mains input voltages of 110V AC and 220V AC to 240V AC.
Issue 4 28
Batteries and charging
Important !
Do not rest a battery on top of the
charger.
Do not stand the charger on a carpet or other soft surface. Always place it on a hard surface.
Do not operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way, take it to a qualified technician.
Do not disassemble charger; only have it repaired by the manufacturers. Incorrect re­assembly may result in a risk of electric shock or fire. To reduce the risk of an electric shock, unplug the charger from the outlet before attempting any maintenance or cleaning.
Turning off the controls will not reduce the risk.
Never place the charger directly above the battery being charged; gases from the battery will corrode and damage the charger.
Never Charge a frozen battery. A fully charged battery will rarely freeze but the electrolyte of a discharged battery can freeze at
Fahrenheit (-9° centigrade), any
16° battery that is suspected of being frozen should be thawed completely before charging.
Note: when buying replacement batteries always consult your sunrise medical service agent.
Note: Before using your vehicle for the very first time, please charge the batteries for a period of 24 hours.
Battery warranty
Battery warranties are subject to periods set by the manufacturers, however, most of these warranties are subject to a wear and tear clause, and if you genuinely wear out your batteries in 6 months, it will not be possible to obtain a replacement under warranty.
Never Smoke or allow a spark or flame in the vicinity of battery or charger. Be extra cautious to reduce the risk of dropping a metal tool on to the battery. It could spark or short circuit the battery or other electrical parts, that may cause an explosion. Also take off all personal metal effects and dangling objects when working on the battery.

Batteries and charging
The range of your vehicle
Most manufacturers of mobility products state the range of their vehicles either in the sales literature or within the Owners Manual. The range stated sometimes differs from manufacturer to manufacturer even though the battery size is the same. Sunrise Medical measure the range of their vehicles in a consistent and uniform manner, but variances still occur due to motor efficiencies and overall product load weight.
The range figures are calculated to
I.S.O. Standard 7176. Part 4: Wheelchair Energy Consumption Theoretical Range
This test is carried out in controlled conditions with new, fully charged batteries, on a level test surface and a user weight of 75kg. The range figures stated should be seen as a theoretical maximum and could be reduced if any single, or combination, of the following circumstances occur:
1 User weight heavier than 75kg.
2 Batteries whose age and
condition are less than perfect.
3 The terrain is difficult e.g. very
hilly, sloping, muddy ground, gravel, grass, snow and ice.
7 Lots of start/stop driving.
8 Also thick pile carpets within the
home can affect range.
All this technical information may seem complicated and a little daunting, but please remember, that the battery sizes available on each Sunrise Medical product should give sufficient range to cope with the majority of customer’s lifestyles.
Myths and legends
Over the years, battery technology has moved forward but, unfortunately, some of the advice given on battery care has not. This has resulted in a number of confused and at times contradictory instructions on the ‘best’ way to care for your batteries. This section will help to dispel some of these myths and legends.
1 Batteries can be charged
immediately after use. You do not need to allow them to cool prior to charging.
2 Mobility batteries do not develop
a memory from using a repetitive charge and discharge cycle. This only applies to nickel cadmium batteries commonly found in products such as camcorders.
4 The vehicle climbs kerbs
regularly.
5 The ambient temperature is very
hot or very cold.
6 Incorrect tyre pressures in one
or more tyres.
Issue 4 30
3 Batteries when new do not
require any special attention with regard to their charge and discharge cycle. Following the relevant ‘care plan’ is the best advice we can give.
User tips
Caution
Please show the utmost consideration for the other traffic on the road.
Remember that the last thing a car or lorry driver expects to see is a wheel chair backing off the kerb into the road. If in any doubt, do not risk crossing the road until you are certain that it is safe.
Always cross the road as quickly as possible; there may be other traffic.
Adverse conditions
Please be aware that when driving your wheelchair in adverse conditions, e.g. on wet grass, mud, ice, snow, or other slippery surfaces you may experience a reduction in the grip and traction of your wheelchair. We recommend you take extra precautions in these conditions, particularly on hills and slopes, your wheelchair could become unstable or skid causing possible injury. Extreme variances in temperature may trigger the self protect mechanism in the control system. If this occurs the control system will temporarily shut down to prevent damage to the electronics or the chair.
Ramps
When using a ramp, please ensure that is capable of taking the combined weight of the powerchair and yourself. If a ramp is being used to load a chair into a vehicle, please ensure the ramp is properly secured to the vehicle. Always approach the ramp head-on and exercise caution (Fig. 30).

User tips
Transfer to and from the chair
Sunrise Medical recommend that you consult your healthcare professional for assistance in developing your personal front or side transfer technique to best suit your needs, and avoid any personal injury (Fig. 31 and 32).

User tips
Gradients: ascents
When going uphill, keep the chair moving. Keep the joystick pushed well forward and steer by moving it from side to side. If you have stopped on a hill, then you should start slowly, and if necessary lean forward to obviate the tendency for the front wheels to lift (Fig.33).
Gradients: descents
On descents, it is important not to let the wheelchair accelerate beyond its normal level of ground speed. In fact, it is safer to proceed slowly down steep descents and stop immediately if any anxiety arises regarding directional control. If the chair picks up speed, centre the control to slow it or to stop all forward movement, then restart slowly and do not allow the speed to increase. The solid state controller has the benefit of a logic system that will help compensate when driving along a camber or up a hill. This is an added safety feature on your wheelchair. In addition of course, you may control the wheel chair speed by using the speed control (Fig. 34).

Transportation
Clamp points
We do not recommend that you transport the F50 in a vehicle, however should you still choose to transport the F50, please clamp the product using a 4 Point Webbing Restraint as per the diagram shown (Fig 35).
Transportation in vehicles
Users should not remain seated in the wheelchair while travelling aboard any form of primary or secondary transportation.
Only permanently installed car seats and seat belts will offer sufficient protection in hazardous situations. When vehicles are in motion, unoccupied wheelchairs should be secured using appropriate means.

Issue 4 34
Lap belt instructions
Note:
Lap belts are fitted as positional aids, and are not suitable as transportation restraints.
Step 1
Place lab belt around chair.
Step 2 Position belt such that fastening
buckle is situated in the middle of the stomach. The positioning belt should be adjusted so that a hand can be placed between the user and the belt.
Step 3
Secure lap belt round back posts using tri-glide fittings.
Maintenance
Check lap belt, and securing components, at regular intervals for any sign of frays, or damage. Replace if necessary.
35 Issue 4
Maintenance
Cleaning
The wheelchair should be wiped over once per week with a slightly damp, not wet, cloth and any fluff or dust that has accumulated around the motors should be blown or dusted away.
Tyre pressures
If pneumatic tyres are fitted to your wheelchair it is important to regularly check the air pressure and for signs of wear.
The correct pressures are between the minimum of 137 kiloPascals (20 psi, 1.37bar) and the maximum 241 kiloPascals (35 psi, 2.41bar) for rear wheels, and 102 kiloPascals (15psi, 1.02 bar).
The pressure will need to vary, depending on the weight of the user. IT IS IMPORTANT that front wheels are inflated to the same pressure as a pair, and likewise the rear. The inflator pump provides the safest method of inflating your wheelchair tyres and the pressure can be checked with a standard motor vehicle pressure gauge.
Do not inflate beyond the maximum tyre pressure.
Electrical connections
When inspecting electrical connections, pay attention to the battery connections, the connection of batteries to power loom and plug in sockets for the joystick, control box and lights and indicators.
Tyre wear
When inspecting the tyres for signs of wear, look for significant scuff marks, cuts and a diminished tyre tread. Tyres will need to be changed when the tread cannot be seen over the complete surface of the tyre.
Upholstery/seating
Tears, dents, wearing or slackening of upholstery particularly near to metal could result in poor posture or lower levels of comfort and pressure relief.
