Product approval
This product meets the requirements of standard EN 12184:2014
The chair is crash-tested in accordance with ISO 10542-5 & 7176-19 – 2008
Check before running
❗The following should be checked before running:
❗The battery’s charge status
❗Set at the required speed
⚠Turn off the control box before getting in and out
Users are advised that changes made to the control parameters and other settings by the user
or other unauthorised personnel are done so at their own risk!
❗Always let the dealer carry out adjustments and settings
Inspection:
Daily inspection:
⚠It is extremely important to check the chair for damage on a daily basis. Pay particular
attention to visible breakages in cables and defects in the rubber bellows on the joystick.
✋If the damage mentioned above is present, the wheelchair should not be used, and
driving it is at your own risk!
⚠If you find that the wheelchair and its accessories are not working as expected, or if there
are unusual noises or a suspected defect, contact your wheelchair supplier as soon as
possible.
Weekly check
Parking brake: This test should be carried out on an even surface, with at least one metre’s
clearance around the wheelchair.
1. Power up the wheelchair.
Check that the wheelchair remains switched on after initialisation and that the
battery indicator shows a sufficient battery level.
2. Push the joystick slowly forwards, until you hear that the parking brakes are
activated. The wheelchair will now start to run slowly.

MANUAL MANUAL
8
3. Release the joystick. You should now be able to hear both parking brakes
being activated within a couple of seconds, and the chair braking.
Repeat the test three more times.
Push the joystick slowly backwards, to the left and to the right.
Connectors and cables: Check that the cables and connector are arranged neatly and not
damaged.
Joystick rubber seal: Check that the rubber around the control stick is not damaged or torn, so
that no water or foreign bodies are able to penetrate.
Joystick mounting: Check that the control box and fittings are mounted properly and are not
loose. Do not over-tighten any screws
Monthly check
❗Check the air pressure in the wheels at least once a month.
Annual check
❗We recommend that the chair is sent for servicing once a year by an authorised
ROLTEC dealer in the country in which it was purchased. Contact your dealer if there are any
problems or if a solution is not described in this user manual.
If your chair is equipped with an electrically adjustable back rest, this should be checked once
a year. Moving parts should be lubricated and checked for wear.
All visible bolts should be re-tightened.
❗Power consumption increases significantly if there is not enough air in the tyres. Different
pressure in the tyres will result in uneven running
Warranty:
The warranty is invalidated if the user has not carried out regular maintenance of the
wheelchair, and the warranty will also be invalidated if the user has undertaken, or allowed a
third party to undertake, repairs, mounting or modifications without ROLTEC’s prior written
consent. Nor does the warranty cover defects or damage caused by incorrect usage or storage
of the wheelchair. The warranty will also be invalidated if the wheelchair is used in a manner
or for a purpose for which it is inherently not suitable.

SAFETY INSTRUCTIONS
General
⚠
If the height is changed using force, with the seat raised or tipped, there is a risk of the chair
overturning. In such case, to minimise this risk, it is important that the seat is raised as little as
possible, and is in a horizontal position with the chair back as upright as possible.
⚠
Driving on surfaces that slope to one side should be avoided, as the tilting may increase the
risk of the chair overturning. When the chair is used on uneven surfaces, the seat should not
be raised, to ensure the chair’s stability.
⚠
Avoid touching leaking batteries, as the contents are corrosive and can be harmful to your
health.
⚠
ROLTEC el-kørestole A/S is exempt from all liability for any accidents caused through
negligence, nor can ROLTEC el-kørestole A/S be held liable for the personal injuries or
material damage that may arise if the user or other person has not followed the
recommendations, warnings and instructions that are given in this user manual. You should
therefore read the instructions for use thoroughly. It contains important warnings and
instructions.
⚠
Increased risk of overturning if lift, tilt and electric back are used.
⚠
ROLTEC Viper is approved for a user weight of 130 kg.
⚠
You should always switch off the wheelchair when getting in or out of the chair - also when
you are being assisted by an attendant, so that the chair does not start to roll if the joystick is
inadvertently activated.
⚠
When the control box is swung out to the side or into place, there may be a risk of getting
caught on the swivel bracket. Take care not to get your own or anyone else´s fingers caught.

MANUAL MANUAL
10
⚠
The wheelchair is EMC-tested. However, this does rule out the possibility of the wheelchair
being affected by electro-magnetic fields, from mobile phones, for example. For this reason,
transportable transmission, receiving and communications devices should not be used or
switched on when the wheelchair is switched on. Should the wheelchair be started up
unintentionally, or if the brakes fail, the wheelchair must be switched off immediately. Note
that this does not rule out the possibility of the chair emitting electromagnetic fields, which may
affect the surroundings, for example, office alarm systems.
⚠
Warning; the chair’s electronics may cause so much electromagnetic interference that store
alarms, for example, and electric gates in the immediate vicinity of the wheelchair can be
affected.
⚠
Exercise particular care when driving down ramps.
⚠
When the chair’s brakes are released, the chair may start to roll if it is standing on a sloping
surface.
⚠
When braking (emergency braking) by pressing the On/Off button, the user’s upper body can
fall forwards and, in extreme cases, this may result in the user falling out of the chair. This form
of braking should only be used as an emergency stop.
⚠
Batteries should be charged in a well-ventilated area.
⚠
If the batteries are damaged and leak, contact your dealer, as it may be hazardous to come
into contact with the contents of the batteries. The wheelchair should then be stored in a dry,
well-ventilated room. Spent batteries should be taken to the local authority’s waste disposal
site for recycling. This also applies to other parts of the wheelchair, e.g. used tyres and tubes.
The whole wheelchair may also be returned to the dealer to be disposed of.
⚠
If there is a strong smell during charging (there may be a fault with the batteries), contact your
dealer, as it may be hazardous to breathe in the vapours from the battery. The wheelchair
should then be stored in a dry, well-ventilated room.

11
⚠
When the wheelchair is exposed to external heat sources, such as the sun’s rays, the surface
temperature may increase so much on some surfaces that you could burn yourself on them.
This applies to dark and black surfaces in particular.
⚠
Warning; the wheelchair’s operating parameters can be adjusted, so they fall outside the limits
specified in the standard (EN 12184). The user must beware of the dangers this can lead to,
such as long braking distances. Always let the dealer carry out adjustments and settings
⚠
Warning; there is a danger of the wheelchair being caught up on poor terrain, e.g. loose sand
or deep holes.
⚠
With regard to fire hazards, it is hereby stated that the combination of the seat’s foam padding
and upholstery has been tested and approved in accordance with EN 1021-1:2006 and EN
1021-2:2006
⚠
Only equipment that is assembled by personnel authorised by ROLTEC may be used.
⚠
When using the chair and its functions, there may be a danger of getting stuck in it. When the
control box is swung in or out to the side, there may be a risk of getting caught on the swivel
fitting.
⚠
A headrest should always be used when the electrical functions - Tilt and Back - are used.
⚠
Beware that, if the chair is left in sunlight, the upholstery can get so hot that it can cause burns.
⚠
The wheelchair’s lift and tilt functions are designed in such a way that it will not fall by itself,
but will only move when these functions are used.
These functions are also designed to ensure continual driving.

MANUAL MANUAL

⚠
If the wheelchair is not secured properly in a vehicle, this may cause damage to the vehicle
itself, the wheelchair or the passengers in the vehicle during the journey. If you do not use a
seatbelt while sitting in a wheelchair, this may lead to serious injuries in the event of an
accident.
⚠
No modifications or replacements should be made to the wheelchair’s mounting points or to
the construction and frame parts or components without consulting the wheelchair
manufacturer.
⚠
A Dahl Docking Station may only be incorporated into a wheelchair by the qualified and
authorised staff of a registered firm that carries out car adaptations. To order Dahl Docking
and accessories, please contact Dahl Engineering in Denmark for further details.
You can find Dahl at www.dahlengineering.dk
⚠
The wheelchair may only be transported in a vehicle that is approved or adapted for such
purposes. It is safer if the wheelchair is separated from the driver’s cabin. Transport in a trailer
is also an optional recommendation. If the wheelchair is transported in a bus, van or other
vehicle, it is essential that the chair is properly secured and that the vehicle’s mounting points
are firmly fixed. In all transport situations, the wheelchair must be correctly secured at the 4 tie-
down points, to prevent the chair from slipping or tilting during the journey. Check that the
wheelchair is properly secured and that the parking brakes are activated. The wheelchair can
be locked in position by attaching the mounting straps through the fittings on the front and
back, each of which has an indication label.
⚠
Follow the vehicle manufacturer’s mounting instructions to secure the wheelchair. Always make
sure that the mounting points on the vehicle are securely fixed. This is strongly recommended,
as the heavy wheelchair may cause serious problems in the event of a road accident.
⚠
If the instructions for use are not followed carefully, this will put the user at great risk of danger
and the wheelchair at risk of damage

Using the PG R network.
General advice on wheelchair control:
The wheelchair is switched off when there is no light on the display, and on when the display
lights up.
The wheelchair’s control system can be in two or more statuses: either ready to drive, or in a
status in which it cannot be driven but where the joystick (control stick) can be used to operate
all electrically powered parts of the chair - leg supports, seat lift, etc. - and make various
adjustments to the chair.
Mode:
If you want to use the control stick for any other functions other than running, you can switch
from drive status to mode status (there may well be several mode statuses) by activating the
mode button, and hence gain access to the wheelchair’s other functions.
Use the mode button to switch from one mode to another.
Apart from the display diagrams that refer to the electrically-powered parts of your wheelchair,
other mode diagrams are available if additional control equipment is fitted
The wheelchair’s electrical functions are activated by moving the control stick either forwards
or backwards.
If the display does not show the part of the wheelchair you want to activate, you can scroll
forward to the required part by moving the control stick to the right or left.
Speed:
The maximum speed can be controlled by using the speed button on the control unit.
The speed bar in the display will show the maximum speed in the profile selected.
The speed can be controlled by using the joystick during driving. If the joystick is moved a little,
the wheelchair will move more slowly.

The wheelchair’s top speed is reduced when the seat is raised or tipped beyond a certain
point. When this happens, it will be shown by an orange tortoise appearing in the display.
Drive profile:
The control unit can be set to make the wheelchair suitable for different environments. For
example, if you select the “Soft” profile, the wheelchair will react more gently. When you are
outdoors, the profile can be set to a more constant driving style.
The name of the current profile is shown at the bottom of the display.
The Profiles button allows the user to navigate through the available Profiles of the control
system. The number of profiles available depends on how the control system is programmed.
Settings menu:
The settings menu enables you to change the clock, the light strength, background light,
