Safety instructions
General
An electric wheelchair is a motorized vehicle and special care must, therefore, be taken
when it is used.
Incorrect use may both injure the user and damage the chair. In order to reduce these
risks, you should read the Owner’s Manual carefully, in particular the safety instructions
and their warning texts.
Any inappropriate modifications to the wheelchair and its various systems may entail an
increased risk of accidents. Carefully follow the recommendations in the Handling section
to prevent the risk of accidents in connection with driving.
All modifications to and interventions in the vital systems of the wheelchair must be
performed by a qualified service technician. Always contact a qualified service technician
in cases of doubt.
Warning
Passengers
It is absolutely forbidden to carry passengers on the wheelchair.
Operation
Always bear in mind that a high speed and extended braking distance make for an
increased risk of accidents. Always use the positioning belt on the Chairman 2s Lowrider.
Never drive rapidly or at full speed along narrow passages, on narrow sidewalks, etc. where
an incorrect maneuver or incorrect steering can cause an increased risk of accidents.
Keep in mind that driving along slopes have an effect on the wheelchair and could make
it steer to the side. Never drive at full speed along slopes.
Use of the seat tilt function displaces the center of gravity, which can have a negative
effect on the chair’s handling characteristics while it is being driven. So you should never
drive at full speed if an extreme seat tilt is being used.
Do not let children drive the wheelchair without supervision.
Do not drive the wheelchair over any edges higher than 3 inches.
When driving downhill, select the slowest speed and proceed with caution.
Do not drive up or down slopes with a gradient greater than 12°*). There is a risk that the
wheelchair will not maneuver safely.
*)Dynamic stability according to ISO 7176-2 = 7°.
Please show great caution where this warning symbol appears. There is
a risk of personal injury.

Owner’s Manual Chairman 2k/2s Lowrider Safety instructions

Operating the seat lift
Ensure that nothing is caught between the chassis and the seat when the seat
lift is operated. Raising the seat lift raises the center of gravity and increases the
risk of tipping. Therefore, you should only use the seat lift on level ground and
not on hilly ground.
Releasing the brakes
In order to avoid the wheelchair rolling away, ensure that the wheelchair is on a
level and dry base before releasing the brakes.
Charging the batteries
The batteries must be charged in a well-ventilated room, not in a closet. Do not
charge the batteries in a bathroom or wet room. Use only chargers with a
maximum 10 A charging current (mean value). When the charger is connected,
the chair must not and cannot be driven.
Transport
Ensure that the wheelchair is properly secured (see page 32).
If the chair is not properly secured and comes loose, it can cause serious injury
to persons in the vehicle and serious damage to the vehicle.
Service
Carry out only the service and maintenance which are stated in the Owner’s
Manual. All other service and maintenance must be carried out by persons with
sufficient technical skill to be able to carry it out in a professional manner.
During all work on the electrical system of the wheelchair, the connection to the
negative pole of the battery must always be removed. Take care when using
metal objects in connection with work on the batteries. Short-circuiting can easi-
ly cause an explosion. Always use protective gloves and goggles.
The recommended air pressure is 29 psi (0.2 MPa). Overfilling entails the risk of
explosion.

General introduction
In order that you can obtain the greatest possible benefit from the chair, it is
important that it is used in the intended manner. We would, therefore, like you to
read the Instructions for Use carefully, in particular the safety instructions. Keep
the Owner’s Manual together with everything else associated with your wheelchair.
The first thing to do is to charge the batteries. Read the chapter Charging the
Batteries on page 30-31 if you are uncertain about how to do this. Charging
takes approximately 9 hours.
Specially adapted wheelchair
If your wheelchair is marked with the decal "specially adapted product", it has
been adapted to your requirements and wishes. This means that its design and
functions may differ from the text in the present Owner’s manual or from the
design and functions of other wheelchairs of the same type.
Specifications
All the information and specifications contained in the present Owner’s Manual
were valid at the time of delivery of this wheelchair. As development and impro-
vement take place continuously at Permobil, we reserve the right to make chan-
ges without prior notification.

Seat
See the supplied Owner’s Manual for the seat.
Seat lift
The Chairman 2k/2s Lowrider is fitted with an electrically control panel operated
seat lift. An actuator device which is controlled from the maneuvering panel
makes it possible to raise the seat up to 6” to adapt the height to tables, ben-
ches, etc. If the seat lift is raised from its lowest position, the wheelchair's max-
imum speed is reduced by 50 %.
Adjusting seat tilt angle
The Chairman 2k/2s Lowrider is fitted with an electric seat tilt actuator adjuster,
which lets you adjust the angle of the seat. The electric seat tilt actuator is con-
trolled from the control panel or from the seat control panel.

Wheels
The front wheels of the wheelchair, the driving wheels, have pneumatic tires.
The rear wheels, the link wheels, can have either pneumatic or solid rubber tires.
Lights and reflectors
In the standard configuration, the wheelchair is equipped with reflectors front,
back and at the sides. Front/back lights and flashing indicators are available as
accessories

Driving
The wheelchair has a drive pack for each drive wheel. The motors regulate the
speed, turning and braking. A joystick on the maneuvering panel sends signals
to the electronics unit placed under the cover on the rear part of the chassis. The
electronics unit then controls the motors.
Shock absorbers
The wheelchair is fitted with two shock absorbers, with adjustable spring force.
If the weight of the user is not specified, the wheelchair is supplied with the shock
absorbers set to a standard value, which is correct for a user from 110 – 154 lbs.
Adjusting spring force
Adjustments should be made by someone familiar with the design and operation
of the shock absorbers. When adjustment is required, contact your nearest ser-
vice engineer/service center or Permobil.
