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.
Page 7
Owner’s Manual Chairman 2k/2s Lowrider Safety instructions
Page 7
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 Acharging 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 easily 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. W e 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 improvement take place continuously at Permobil, we reserve the right to make changes without prior notification.

Handling
General
This wheelchair is designed for use both inside and outside. When driving inside, take normal care. Outside you must remember to drive very slowly on steep
downhill slopes and not to drive over curbs and other obstacles higher than
3 inches.
Do not make the first test run on your own. The test run is to find out how you
and the wheelchair work together and you may need some assistance.
Driving
1. Switch on the wheelchair by pressing the start button on the control panel.
Fig. 22. Start button
Owner’s Manual Chairman 2k/2s Lowrider Handling

Fig. 23. Speed selector
Always bear in mind that high speed and extended braking distance entail
an increased risk of accidents. Always use the positioning belt when
seated in your powered wheelchair.
Owner’s Manual Chairman 2k/2s Lowrider Handling
Page 25Page 25
Fig. 25. Steering
4. The speed of the wheelchair is regulated proportionally by moving the joystick
forwards or backwards to different extents. The wheelchair's electronics make it
possible to move slowly over curbs and other obstacles. You can drive up to the
curb or obstacle and then carefully drive over it.
When you drive down an obstacle or a steep slope, you must drive slowly and
brake gently. The maximum speed should be set to low speed. You can brake
gently by pulling the joystick back to a position just before the neutral position.
When the speed has been reduced, you can let the joystick go.
Always bear in mind that high speed and extended braking distance entail an
increased risk of accidents. Always use the positioning belt when seated in your
powered wheelchair.
NB: The wheelchair moves at reduced speed if the seat is raised. You can only
drive at full speed if the seat is in its lowest position. Raising the seat also raises
the center of gravity and increases the risk of tipping. Therefore, you should only
adjust your seat height when driving on level ground and not on hilly ground.
Steering
The wheelchair can be turned in the required direction by moving the joystick to
one side or the other while driving forwards or backwards.

Fig. 32. Charging socket
When should the batteries be charged?
As a general rule, you should recharge your batteries as frequently as possible
to assure the longest possible life and to minimize the required charging time.
Plan to recharge them when you do not anticipate using the chair for a long period of time.
A battery voltage indicator on the control panel indicates when the battery voltage is low (see figure on page 16). The batteries must then be charged as soon
as possible.
If the batteries should become completely discharged, it is important that you
recharge them as soon as possible. If you delay before recharging them, the batteries can be damaged.
Charging
1. Connect the charger to the 110 volt supply.
2. Connect the charger cable from the charger to the charging socket, Fig. 32,
on the wheelchair.
NB! When the charger is connected, the chair must not and cannot be driven.

If the wheelchair is equipped with maintenance-free gel batteries: in some airlines it is not necessary to remove the batteries from the wheelchair during the
flight. However, the electrical connections to the battery must be disconnected
and insulated. Check with your airline which rules apply.
If a wheelchair is equipped with acid batteries, most airlines require that the batteries shall be removed from the wheelchair and transported in special boxes
provided by the airline.
Some airlines refuse to take acid batteries aboard at all, so always check with
the airline in question which rules apply.
See page 39 for how to remove the batteries.
The dimensions and weight of the wheelchair
The weight and dimensions of the wheelchair are significant in relation to the
type of airplanes in which the wheelchair is to be transported. Always check with
the airline in question which rules apply.
Preventing damage
Cover the control panel with soft, shock-absorbing material (foamed plastic or
similar) and fold it in towards the back rest. Protect other salient objects in similar fashion. Tape any loose cables to the seat or covers.
NB!
To ensure that the chair is transported safely and that no nasty surprises pop up
at the last minute, always contact the airline with which you are travelling
beforehand.

Maintenance and Repairs
To ensure that your wheelchair works well, it is important that it is well looked
after. Every wheelchair is subject to wear, partly between the moving parts and
partly on account of strains and stresses. Therefore, you must know how the
wheelchair works, how you are to drive it and use it correctly and how you are
to look after it.
Preventive maintenance is intended to prevent faults. If you look after your
wheelchair, it will work well and the risk of faults is reduced.
Owner’s Manual Chairman 2k/2s Lowrider Maintenance and Repairs
Page 35Page 35
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 engineer. Always contact a qualified service
engineer in cases of doubt.
WARNING
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 easily cause an explosion. Always use protective
gloves and goggles.

Maintenance
General
• Batteries discharge themselves and must be charged and maintenance-char-
ged to prevent them from being damaged.
• The wheelchair must not be stored in rooms in which condensation occurs
(mist or moisture on surfaces), i.e. laundry or similar rooms.
• The wheelchair may be stored in an unheated room. From the point of view
of corrosion, it is best for the chair if the room is a few degrees warmer than
the surroundings, which keeps the room drier.
Short-term storage
In order for the charging process to produce a battery with good capacity, the
temperature in the storage room should not be less than 41 F. Storage at less
than 41 F increases the risk that the battery is not fully charged when it is used
and also increases the risk of corrosion.
Long-term storage
The chair may be stored in an unheated room but the battery should be maintenance-charged at least once per month. See also Short-term storage above.

Cleaning
Clean the wheelchair often. It is especially important to clean it after it has been
used outside. Use a damp rag with a mild soap solution to wipe off dirt and dust.
NB! Do not use a hose to wash the wheelchair with water. The electronics can
be damaged.
Wheels
Check regularly that the air pressure in the tires is correct. Fill with air if necessary.
Check of brake release
Check regularly, approx. once per month, the brake release function by engaging and disengaging the brake release a number of times.
Batteries
Storage
Please note that batteries discharge of their own accord and that a discharged
battery may freeze and burst when it is cold. If the wheelchair is to be stored and
not used for a long period of time, the batteries must always be charged once
per month to avoid damaging them.
NB! The temperature in the storage room should not be less than 41 F.
If your wheelchair is equipped with acid batteries, the level of acid should be
checked regularly.
If your wheelchair is equipped with gel batteries, there is no need to check the
liquid level.
The durability of the batteries depends entirely on regular charging.

Resetting the main fuse/battery cut-out
The main fuse also functions as a battery cut-out but is still referred to as the
main fuse in the user instruction.
NB! First switch off the power on the maneuvering panel before switching the
power off on the main fuse.
Main fuse
You don’t normally need to change the main fuse, as you can reset it when it
trips. You reset it by switching it to the "ON" position. The main fuse is located
on the top side of the chassis behind the seat lift, see Fig. 35.
NB! If the main fuse trips, it usually means that there is a serious
electrical fault. Check the cause carefully before you reset the circuit breaker.
Changing the charging fuse
The fuse holder for the charging fuse is below the charging outlet at the front
edge of the wheelchair’s chassis cover.
NB! The chair should be switched off when changing the charging fuse.

1. Block up the wheelchair and let out the air.
2. Pull the tire off the wheel rim.
3. Change the punctured inner tube.
4. Replace the tire on the wheel rim and fill with air.
Low air pressure in the tires produces abnormal wear and reduces the range.
Therefore, check regularly that the tires have a pressure of 29 psi (0.2 MPa).
1. Unscrew the plastic caps on the air valves of the front and rear tires.
2. Connect the air nozzle to the valve and adjust the tire pressure to the stipu-
lated level.

Owner’s Manual Chairman 2k/2s Lowrider Important information
Page 48Page 48
CAUTION! It is very important that you read this information
regarding the possible effects of electromagnetic interference
on your powered wheelchair.
Electromagnetic Interference (EMI) From Radio Wave
Sources
Powered wheelchairs and motorized scooters (in this text, both will be referred
to as powered wheelchairs) may be susceptible to electromagnetic interference
(EMI), which is interfering electromagnetic energy (EM) emitted from sources
such as radio stations, TV stations, amateur radio (HAM) transmitters, twoway
radios, and cellular phones.
The interference (from radio wave sources) can cause the powered wheelchair
to release its brakes, move by itself, or move in unintended directions. It can also
permanently damage the powered wheelchair’s control system. The intensity of
the interfering EM energy can be measured in volts per meter (V/m). Each
powered wheelchair can resist EMI up to a certain intensity. This is called its
”immunity level”. The higher the immunity level, the greater the protection.
At this time, requested immunity level as per EN 60601-1-2 is 3 V/m. The immunity level of this powered wheelchair model as shipped, with no further modification, is >20V/m in the range of 26 MHz to 950 MHz.
There are a number of sources of relatively intense electromagnetic fields in the
everyday environment. Some of these sources are obvious and easy to avoid.
Others are not apparent and exposure is unavoidable. However, we believe that
by following the warnings listed below, your risk to EMI will be minimized.
The sources of radiated EMI can be broadly classified into three types:
1.
Hand-held portable transceivers (transmitters-receivers) with the antenna
mounted directly on the transmitting unit. Examples includes: citizens band (CB)
radios, ”walkie talkie”, security, fire, and police transceivers, cellular telephones,
and other personal communication devices.
NOTE! Some cellular telephones and similar devices transmit signals while they
are ON, even when not being used.
2.
Medium-range mobile transceivers, such as those used in police cars, fire
trucks, ambulances, and taxis. These usually have the antenna mounted on the
outside of the vehicle.
Owner’s Manual Chairman 2k/2s Lowrider Important information
Page 49Page 49
3.
Long-range transmitters and transceivers, such as commercial broadcast
transmitter (radio and TV broadcast antenna tower) and amateur (HAM) radios.
NOTE! Other types of hand-held devices, such as cordless phones, laptop computers, AM/FM radios, TV sets, CD players, and casette players, and small appliances, such as electric shavers and hair dryers, so far we know, are not likely to
cause EMI problems to your powered wheelchair.
Because EM energy rapidly becomes more intense as one moves closer to the
transmitting antenna (source), the EM fields from hand-held radio wave sources
(transceivers) are of special concern. It is possible to unintentionally bring high
levels of EM energy very close to the powered wheelchair’s control system while
using these devices. This can affect powered wheelchair movement and braking. Therefore, the warnings listed below are recommended to prevent possible interference with the control system of the powered wheelchair.
WARNINGS
Electromagnetic interference (EMI) from sources such as radio and TV stations,
amateur radio (HAM) transmitters, two-way radios, and cellular phones can
affect powered wheelchairs and motorized scooters. Following the warnings listed below should reduced the chance of unintended brake release or powered
wheelchair movement which could result in serious injury.
1.
Do not operate hand-held transceivers (transmitters/receivers), such as citizens
band (CB) radios, or turn ON personal communications devices, such as cellular phones, while the powered wheelchair is turned ON.
2.
Be aware of nearby transmitters, such as radio or TV stations, and try to avoid
coming close to them.
3.
If unintended movement or brake release occurs, turn the powered wheelchair
OFF as soon as it is safe.
4.
Be aware that adding accessories or components, or modifying the powered
wheelchair, may make it more susceptible to EMI.
(Note: There is no easy way to evaluate their effect on the overall immunity of
the powered wheelchair).
5.
Report all incidents of unintended movement or brake release to the powered
wheelchair manufacturer, and note whether there is a radio wave source nearby.
