TGA Power Pack

The TGA series four has undergone some major updates which have seen an external gearbox unit re-design and some re-designed chassis upgrades including a battery bag with matching lifting straps, added alloy wheels and super grip tyres. Traction control has also been added to give a smooth start without wheelspin.

The electronic control system has seen an upgrade and now uses the very latest in micro processor technology with a host of advanced safety features. Ergonomic changes include a redesigned handlebar control which is a replacement for the standard wheelchair handlebar grips. This easy to use control feature is an important handlebar extension for optional left or right hand use.

The key which operates the on/off switch is now removable giving greater security. There is now an on/off light indicator with red, amber and green colours advising you of battery condition. A pre-set speed control governing top speed and a thumb operated speed control lever have been added.

The range has been expanded to include three models:

The standard single wheel version capable of transporting up to 18 stone user weight.

The twin-wheel model with the same user weight limit but much greater traction – really effective on loose gravel and wet grass.

The heavy duty version is only available with twin wheels and is capable of transporting up to 26 stone.

The powerpacks ease of use allows you to attach it to any wheelchair in literally seconds and once fitted you will never have to push the chair again. With your thumb on the control you can walk along and let the powerpack do all the work. The powerpack will give you a top speed of 4mph and a range of up to 10 miles so you ill have more than a enough capacity for a good day out.

Where Can Scooters Be Used

TYPES OF CLASS 2 SCOOTERS

Legally these scooters can travel up to 6.4kph (4mph) on pavements and
are allowed on the road to cross from one side of the road to the other.

TYPES OF CLASS 3 VEHICLES

The main difference between Class 3 and Class 2 vehicles is that

Class 3 vehicles tend to be larger and can be used on the roads
where they can travel up to 12.8kph (8mph).

It is usually possible to drive at 6.4 kph (4mph)and switch to
12.8kph (8mph).

Class 3 vehicle users do not require a driving license but should
obey the highwaycode at all times.

This includes complying with
relevant eyesight requirements and not driving under the influence
of alcohol, drugs etc.

Class 3 vehicles are not allowed on motorways, bicycle tracks or
bus/cycle lanes.

Although legally allowed on dual carriageways, this is not
recommended.

Speed

Two speed settings, usually changed by a switch.

12.8kph - maximum speed
Permitted only on the road. Not for use on the pavement or footpath.

6.4kph - 4mph maximum speed
Permitted on the pavement or footpath.

Lights/indicators/horn/rear view mirror/rear reflectors
The law requires class 3 vehicles to be fitted with
all these features.

Flashing beacon
Optional - can be used when driving on the road to warn other road

users of their presence, and must be used if driving on a dual
carriageway although we do not recomend this.

Insurance is not legally required for any powered vehicle in
either category, Class 2 for pavement use or Class 3 for
pavement and road use.

However, it is recommended that the purchaser have
at least public liability Insurance, covering accidental damage
to other people and property.
See our information page on Scooter Insurance.

The legislation governing vehicle registration, licensing and the payment of

vehicle excise duty (VED) is contained in the Vehicle Excise and Registration
Act 1994 (VERA)(as amended).

Under the provisions of VERA, all mechanically
propelled vehicles used on a public road must be licensed (i.e. display a tax
disc) and registered.

However, because class 2 invalid carriages have limited
road use, the Department exempts them from these requirements on an
extra-statutory basis.

No such exemption exists for class 3 invalid carriages.

Schedule 2 to VERA, exempts from the payment of VED any vehicle which does not
exceed 508kgs unladen and which is adapted, and used or kept for use, for an
invalid.

The Road Vehicles (Display of Registration Marks) Regulations 2001 provides the
requirements for displaying registration plates. Vehicles that meet the
definition of an invalid vehicle within these regulations are exempt from
displaying registration plates. “Invalid vehicle” within these regulations
means “a vehicle, the unladen weight of which does not exceed 254kgs and which
is specially designed and constructed, and not merely adapted, for the use of a
person suffering from a physical disability and solely used by that person.”

In short, this means that class 2 invalid carriages are exempt from the
requirement to be licensed and registered. Class 3 invalid carriages, however,
should be registered for road use, licensed in the exempt “disabled” taxation
class and display a nil duty vehicle licence (tax disc).

There is no requirement
to produce a VED exemption certificate when licensing an invalid carriage.

In order to first register and license a class 3 invalid carriage, the user
needs to complete form V55/5 (for used vehicles) or V55/4 (for new vehicles) -
and take or send it to their nearest DVLA local office (addresses can be found
in DVLA’s information leaflet V100 - available from post offices that issue tax
discs - and on the DVLA website). Evidence of the vehicle’s age (or newness)
needs to be submitted with the application together with documentation
confirming the keeper’s name and address.

Electric Mobility Scooters - What to look for...

Electric mobility scooters are available as three or four wheeled machines. Three wheelers have a smaller turning circle but four wheelers may offer more stability.

Some mobility scooters now have four wheels but the front wheels are closer together then a true four wheeled scooter, these scooters sometimes offer more stability then a three wheeler and more manaurvrability then a true four wheeled scooter.

Remember that a smaller mobility scooter that folds very small may not have as much leg room.
Check the weight limit for the scooter, does it have the capacity to carry you?

Your mobility scooter will need regular charging so you must have access to electricity. If you are charging your machine outside a plug-in circuit breaker will provide extra safety.

You will need to keep your machine somewhere safe and dry . Inside a garage or house is ideal, although many people quite successfully keep them outside under a waterproof rainproof cover.

Charging most electric mobility scooters indoors is extremely simple, plug it in, just as you would a kettle.

With some mobility scooters you can also charge the batteries on there own (off of the scooter, this is often found on travel scooters). This is ideal if you are keeping a mobility scooter in a car for use on days out.

Consider what you want the scooter to do for you. Do you want it to take you up very high kerbs and over rough ground, or just normal pavements and smooth grass? If you wish to go over rough ground you should look at the larger type of machines with larger wheels. These can be more difficult to store because of their size and will cost more than smaller machines.

How does an electric mobility scooter operate?

You make an electric scooter 'go' by pushing a small lever called a wig-wag.

It is shaped like a teaspoon with two handles. Push the right lever with your thumb, and you ease forward, push the left lever and you very gently move backward. When you push the lever in just a little you move very slowly. Push in more and you go faster. Some of the electric scooters featured on this site will have this reversed offering finger control this may be preferred and is just as smooth, look for a electric scooter with master speed control, a dial that restricts how fast the scooter will go no matter how far you push the wig-wag.

You steer a mobility scooter just like a bicycle - by turning the handlebars in the direction you want to go. On a electric scooter, the handlebars and instruments are incorporated into a unit called the tiller. For ease of use, the tiller is adjustable so it can best fit your height and arm length

You make a mobility scooter stop by doing nothing. As soon as you stop pressing the wigwag, the brakes automatically activate and bring the scooter to a gentle stop. This is called passive braking, and it works even if all the power to the electric scooter is cut off. It is the safest braking system possible and will stop the scooter even on a steep hill.Some scooters will also come with an emergency brake (most class three scooters have this)

You can learn to operate an electric scooter in five minutes, and design features that make it easier to use will let you enjoy riding it for years to come.

Electric mobility scooters come with a freewheel lever to permit easy rolling of the scooter when there is no power; long range batteries, so you can travel longer and further without running out of power; non-marking tyres, so you don't mark floors; larger wheels for greater outdoor traction and ground clearance, a tiller mounted recharge plug so you don't have to bend down to plug in the power cable; and colour indicator lights to tell you the status of the battery.

Riding electric scooters can improve your safety. When you ride a mobility scooter you don't have to worry about tripping or losing your balance, or getting tired and having to sit down.

Most models have an anti-tip device behind the back wheels for increased safety on steep gradients. They have a powerful electric motor to give you the power you need for going uphill. Make sure the motor drives the rear wheels for maximum traction.

Some other safety features to look for and consider:

• Master key operations so no-one can ride your scooter except you.
• A locking seat and tiller for better stability when riding.
• Reflectors so you'll be seen in low light conditions.
• Front bumpers to absorb minor impacts without damage.

Electric scooters must remain comfortable not just for a few minutes, but over several hours of operation. Some seats are made from orthopaedic foam for maximum comfort and support. Most seats can be adjusted both up and down and back and forth. They may also rotate into four positions for easy entry and exit, then lock in the straight ahead position for safety while riding. Armrests are often adjustable for width.

Once you think you know what type of scooter you require, Shop around at your local showrooms or shopmobility scheme to select a scooter which suits your needs. You can always ask friends or neighbours about their machines, even strangers can be keen to give you information about their scooters or maybe even encourage you to have a try.

Insurance

• Mobility products open up whole new avenues of opportunity in both the ability to get out and about to become more mobile around your home.
  

• It is therefore of the greatest importance that you are comprehensively protected against any eventuality such as having an accident, your product stolen, damaging someone else's property or even bumping into them causing injury. The financial consequences of such an incident can sometimes be substantial and you could be held liable for legal claims and costs made against you.

• Public awareness and incidence of such cases has dramatically increased as a result of the recent spate of media advertising.

• Premier Care takes of any such instances and leaves you free to enjoy complete peace of mind when making the most of your mobile product.

• Mark Bates Ltd, an independent intermediary, has built a reputation for excellence in providing quality care and attention to our customers by being able to identify and understand their needs, dealing with putting matters right when they go wrong, quickly, fairly and without fuss.

Highway Code

Driving Your Scooter Safely

Modern scooters are equipped with many safety features that can protect the rider and the vehicle when out and about. Although accidents involving scooters are very rare, a scooter is not a car and can be small and vulnerable in comparison. When riding your scooter on roads and pavements it is important to take every precaution to prevent accidents.

The British Healthcare Trades Association has produced The Highway Code for Electric Scooters and Wheelchair Users - a guide to staying safe when using a scooter or wheelchair. Some important points are listed below:

Before buying a vehicle…

• Make sure you are able and fit to use it safely
  See well enough to be safe,Adequately control your vehicle and be able to do all the possible manoeuvras such as reversing, climbing and descending kerbs and turning safely.Cross busy roads (this is not as easy on a scooter as on foot)
  
• Make sure your vehicle is the right one for you
  You should choose a vehicle that you can find a comfortable driving position - considering things like seat height and tiller position.The reasons for choosing a three or four wheeled vehicle are varied and can depend on many factors such as your weight height and perhaps if the scooter is to be folded or not. You will need to be extreamly careful when assending and descending kerbs and when turning as if it not done correctly the scooter may tip over.
• Do not be ambitious where distance is concerned
  The range given in the manufacturer's literature is just a guideline. The full range will vary depending on user weight, the state of the terrain and the amount of charge left in the batteries.

Sensible guidelines for safety…

• When using the footpath
  Just because you are on the footpath or pedestrian precinct does not make you a pedestrian. If you are on a motorised vehicle you are no longer a pedestrian. Remember that pedestrians always have right of way.Many people on foot will be kind and helpful to drivers of a wheelchair or scooter .But not everyone.In a crowded precinct or market area it is your responsibility to ensure you do not run in to anyone or do any harm with your vehicle.While many people will make room for you you cannot expect everyone to do so.
  
• When climbing or descending kerbs
  Always approach at right angles, with your front wheels straight to the kerb. In some powerchairs it is necessary to descend high kerbs backwards. Do not try to climb or descend kerbs higher than the manufacturer recommends.
• Watch out for children, elderly people, disabled people on foot, people with visual problems or impaired hearing, other motorised vehicle users.You may be doing all the right things but this does not guarentee everyone will do likewise
  

When you need help…

• Don't struggle to do the impossible, or even the very difficult things when there are people around who would help if asked.
• When inside shops and buildings
  It is your responsibility to drive safely and not damage fittings, stock or hurt other shoppers or store workers. Don't risk pulling down a whole display to reach the top shelf. Ask for help!
• Speed in shops and buildings - reduce it!
  Set the speed control to a lower setting.Be especially careful if you need to reverse.
  

On the road…

• Remember you are not driving a car, but a very small and slow vehicle, which is therefore more vulnerable.
  If it is possible, use the footpath. It is wise to avoid using roads, particularly busy ones.
• Remember although it is legal to ride all vehicles on the road, it is not always safe or sensible to do so. You are responsible for your own safety and that of other road users. The normal rules of the road apply - but modified.
• Observe the law
  Never drive against the traffic
  Give way where cars would give way. Give way to pedestrians
  Obey Traffic lights and all other road signs and signals and remember the car you can see when you look behind you is almost certainly moving faster then you, It could well be upon you before you complete your manoeuvre and it may not be able to stop in time.

Battery Care

TAKING CARE OF YOUR BATTERIES

How to prolong the life of your battery. When you first install your new battery, place it on charge for at least 24 hours.
If your vehicle is stored for any length of time, firstly charge fully then disconnect your batteries.

Charging Battery technology has changed conciderably over recent years. Batteries today, especially gell/sealed batteries, offer more power for their size and provide longer performance. Try wherever possible to fully cycle your battery before charging and then fully charge before re-use. Always use the correct charging system for the batteries in use. Never use Car chargers on Gell batteries. Never completly discharge your battery.

Warning! Batteries can be hazardous. All batteries, wet, sealed and gell units contain lead and sulphuric acid, both are highly toxic and sulphuric acid is highly corrosive.

Charging

Here are some simple rules for proper battery charging.

• Use the chair manufacturer's automatic charger for all routine charging. (leave your automatic charger turned on whenever possible, you cannot over charge a battery when using automatic 3 stage chargers.)
• Never run your batteries completely flat.
• With smaller travel scooters charge after every days use
  

Battery Life

• Your battery will wear out with age or frequency of use, as the battery gets older your scooter will travel slower or shorter distances.
• If you use your scooter very regularly then the battery will obviusly wear out faster.

Distance

• The distance you can expect from fully charged batteries will be greatly influenced by weight and terrain.

How Often Should You Charge

• Daily users - charge daily as soon as you are done using it.Your scooter will be ready each morning to give you a full days service
• If you use your scooter infrequently(once a week or less),charge the batteries once a week for 12 to 14 hours
• With smaller travel scooters charge after every days use
• Remember to always remove the key from your scooter so it is not accidently left on
  

Battery Storage

• Store batteries fully charged. Check once a month and recharge as needed. Wet batteries can hold their charge up to three months, selaed models six to twelve months. Remember if storing your chair for longer than a few weeks, it's best to charge the batteries and then disconnect them.

Undercharging
A battery operated with insufficient charge over a long period of time may develop a type of sulphate on the plates. This sulphate is dense and hard, and cannot be readily converted to normal active material again. In this condition the battery is unable to deliver it's full power.
