1. PREFACE AND INTRODUCTION

 Please carefully read this owner’s handbook before

using the scooter to ensure that you operate the
scooter safely. Improper use of the scooter could
result in damage, injury or traffic accidents.

 This handbook also advises how to get the most out

of your scooter by giving comprehensive operating,
assembly and maintenance instructions for the
scooter.

 A repair and maintenance record chart and

warranty information is included with this
handbook. Please keep it in a safe place or with the
scooter.

 If someone else uses the scooter make sure that you

provide him or her with this handbook for their
consideration.

 As designs change some of the illustrations and

pictures in the manual may not correspond to the
scooters that you purchased. We reserve the right
to make design modifications.

 The Viper scooter has been designed and

manufactured to provide a comfortable and secure
yet affordable solution for some mobility
requirements. It is suitable for mainly road and
outdoor use and has a top speed of 8mph. It can be
used indoors and on the pavement where the
environment permits and when the scooter is set to
the indoor speed setting. It is a class 3 scooter as
defined by the Road Traffic Act 1988.

2. SAFETY

Before Driving

 The user needs to be familiar with the use and

operation of this scooter before driving.

 The scooter may only be driven on the pavement or

pedestrian areas at speeds up to 4mph (6.4kph). Use
the High / Low button on the lower setting to ensure
you do not exceed this speed. The scooter may be
driven on single carriage roads with the button set to
High. This will allow speeds up to 8mph (12.8kph).

 Be aware of traffic and other road users when

crossing or using roads.

 Never ride on motorways or dual carriageways.
 Use extreme caution when driving your scooter in

busy areas such as shopping malls.

 Do not drive the scooter under the influence of

drink or drugs, or when you are tired. Driving under
the influence of alcohol or drugs may be an offence
under the Road Traffic Act.

 Be careful when using the scooter in low light.
 Before using the scooter in busy or hazardous

environments, familiarise yourself with the
operation of the scooter. Practice in an open and
safe area which is free from hazards and other
people. Reduce your speed to a minimum for your
initial practice.

 Practice operating your vehicle

Before using the scooter in busy or potentially
dangerous areas, familiarize yourself with the
operation of your scooter. Please practice in a wide
and open area like a park. In order to avoid
accidents with your scooter whilst driving, bear in
mind driving motions such as accelerating, braking,
turning, reversing and gradients.

1. Reduce your speed to a minimum for your initial

practice

2. For safety, ensure somebody accompanies you

when driving on the road for the first time

3. Only use the higher speed setting when you are

confident that you can easily operate and
control your scooter

Whilst Driving

Do not move your body out of the vehicle whilst moving

 Such action may cause you to lose your balance

and risk injury from falling

garments do not get tangled or caught in the
wheels

Do not use your vehicle in the following environments

Gradients and Drops

 Do not drive on roads with large drops or

potholes. Such drops or potholes may cause
damage and/or injury.

 Do not cross wide water gutters where there is

a risk of getting the wheels stuck.

Warning

Do not set in freewheel mode when driving on
a gradient.

Always re-engage the anti-freewheel device
before use. Failure to do so may result in
injury.

 To protect your safety, the power will

automatically cut off and the electromagnetic
(EM) brake will activate while you are driving
down gradients over 15º. This will limit the
speed to a safe level. Switch the power off and
on again to restart your scooter.

 The scooter is capable of climbing an 80mm (3”)

obstacle from a stationary start or a 100mm (4”)
obstacle from a moving start.
