Warning
Use extreme caution when you see this warning symbol. There is a risk
of injury.
Owner’s Manual Chairman HD Safety instructions

Safety instructions
General
A wheelchair is a motor-driven vehicle, so be very careful when using it.
Incorrect use can cause a risk of injury or damage to the chair. To reduce these
risks, you should read the operating instructions carefully, especially the safety
instructions and warnings.
Any improper modification of the wheelchair and its systems can increase the
risk of accidents. Follow the recommendations in the section on Operation, in
order to avoid risks when driving.
All modifications to, and interference with, the key systems of the wheelchair
should be done by a qualified service engineer. Always contact a qualified ser-
vice engineer if you are in doubt.
Passangers
The wheelchair is not intended for carrying passengers, whatever their age.
Maximum weight of user
The HD seat can be used by someone weighing up to 400 lbs.
Driving
•Do not drive the wheelchair over edges higher than 2”.
• Observe caution when driving downhill, and always drive slowly.
• Do not drive up or down gradients greater than 12 degrees*). On steeper
gradients, there is a risk that you won’t be able the maneuver the chair safely.
• Do not drive the wheelchair where the sideways gradient is more than
7 degrees. There is a risk of tipping.
*)Dynamic stability according to ISO 7176-2 = 7°.

Owner’s Manual Chairman HD Safety instructions
Page 7
Operating the seat lift
Make sure nothing gets jammed between the chassis and the seat when you are
operating the seat lift. The center of gravity is higher when the seat is raised,
increasing the risk of tipping. So use the seat lift only on flat ground and not on
uneven surfaces.
Releasing the brakes
Make sure the wheelchair is on a level surface before you release the brakes,
so it doesn’t rolling away.
Charging batteries
Charging should be done in a well-ventilated area, not in a wardrobe or closet. You
should not charge the batteries in a bathroom or wet area. Only use a charger with a
maximum charging current of 10A (mean value). You should not try to drive the chair
when the charger is connected, since this will not work.
Transportation
Ensure that the chair is properly secured (see page 31). A chair that is not pro-
perly secured can cause injury and damage if it comes loose.
Servicing
Only attempt the servicing and maintenance that the operating instructions say
may be done by the user. All other servicing and maintenance should be done
by someone with sufficient knowledge to be able to do it correctly.
Always disconnect the negative terminal of the battery before you work on the
electrical system of the wheelchair. Take care when using metal objects while
working on the battery. A short circuit could easily cause an explosion. Always
use protective gloves and glasses.
The recommended air pressure is 36 psi. The tire could explode if you over-inflate it.

Owner’s Manual Chairman HD General introduction
Page 8
General introduction
The Chairman HD is a flexible chair, which is intended for users between 265
and 400 lbs. It has many installation options and can be quickly modified for
different requirements.
The seat is made up of modules. The seat frame forms the basic support, and
is supplemented with a choice of seats, backrests, armrests and leg supports.
The modular system makes it easy to change and reuse the various parts.
In order to get the best possible use from your wheelchair, it is important to use
it in the intended way. We therefore advise you to carefully read the operating
instructions, especially the safety instructions. Keep the operating instructions
with the rest of the things belonging to the chair.
The first thing you should do is to charge the batteries. If you’re not sure what
to do, read the chapter on Battery charging on pages 29-30. Charging takes
about 9 hours.
Specially modified wheelchairs
If your wheelchair is marked with a “Specially modified product” sticker, it has
been modified to your specific needs and wishes. This means that the design
and functions could be different from the text in these operating instructions, or
the design and functions of other wheelchairs of the same type.
The seat can also contain parts that are unique to your chair. These aren’t avai-
lable as spare parts, and must be made as required. This can affect the repair
time of your seat.
Specifcations
All information and specifications given in these operating instructions where
applicable when this wheelchair was delivered. As Permobil carries out continu-
al development and improvement, we reserve the right to make changes without
prior notice.

Drive
The wheelchair has a drive unit for each drive wheel. The motors control the
speed, turning and braking. A control stick on the control panel sends signals to
the electronic unit under the cover at the rear of the chassis. The electronic unit
then controls the motors.

Fuses
There are four fuses in the wheelchair: main fuse, charge fuse, seat
lift/lights/24V switched and 24V unswitched. The main fuse is fitted above the
electronic unit, the charge fuse is in the thin red cable that goes to the positive
terminal of the battery, and the remaining two fuses are in the electronic unit.

Joystick
You use the joystick to control the for-
ward and backward speed, to steer and
to brake.
You can control the speed steplessly by
moving the joystick forwards or back-
wards. The speed is directly proportional
to the movement of the joystick (small
movement for low speed – large move-
ment for high speed).
You steer the chair by moving the joystick
to one side or the other.
The brakes come on when you move the
joystick back to the neutral position or
release it completely. Fig. 20. Joystick
