PREFACE
First of all we want to thank you for putting your trust in us by selecting one of our wheelchairs.
The electric wheelchairs supplied by Vermeiren are the result of reseach and experience over many
years. During development simplicity of operation and servicing were especially emphasised.
But the expected working life of your vehicle depends essentially on your care and maintenance. This
instruction manual will help you to familiarise yourself with the operation of your wheelchair and advise
you about keeping your electric wheelchair in a good operating condition to ensure a long working life.
This instruction manual reflects the latest level of development of the product. However, our firm,
Vermeiren, reserves the right to introduce changes without any obligation to adapt or replace
previously delivered models.
Kindly keep in mind that your wheelchair will be in an excellent working condition and function
perfectly even after many years, if you follow our advice.
For any further questions, please consult your specialist dealer.

THE OPERATING ELEMENTS
The electric wheelchair is delivered fully assembled. Only the footrests have to be fixed (see the
relevant description). Your dealer delivers the wheelchair fully assembled and explains the various
operating elements and their use. However, for your own safety we provide a further, detailed
explanation of the different parts.
The steering and control unit built into your electric wheelchair enables you to control all the driving,
steering and braking processes of the vehicle. The wheelchair's electrical unit and electronics are
constantly being monitored internally. Any fault in the electronics is indicated on the steering unit and,
if necessary, the wheelchair is switched off for reasons of safety (see the chapter on fault analysis).
Consult your specialist dealer if this happens.
The TRACER model can be fitted with equipment which can electrically adjust the inclination of the
seat and the backrest, as well as the height of the footrests.
ADJUSTING THE STEERING UNIT The steering unit's horizontal position can be changed
by loosening screw (1). The unit can then be adjusted
as desired, or removed. Screw (1) must then be
retightened properly. If screw (1) is pulled to the side,
the steering unit can be turned to the side.
LMake sure that the steering unit's connection cable stays clear of the pincer mechanism.
DX2 STEERING UNIT
The steering and control unit built into your electric wheelchair enables you to control all the vehicle's
driving, steering and braking processes and to control other adjusting motors (options: lifting column
and seat/back adjuster and leg supports). The wheelchair's electrical unit and electronics are
constantly being monitored internally. Any fault in the electronics is indicated on the operating display
(6) and the status display (1) and, if necessary, the wheelchair may be switched off for reasons of
safety (see the chapter on fault analysis).

SEAT AND BACK
In the standard version your TRACER has a fixed seat and a fixed backrest which can be adjusted
mechanically. As an optional extra the seat can be inclined electrically and the back can also be
adjusted electrically.
MECHANICAL ADJUSTMENT OF THE BACK
For easier stowing of the electric wheelchair in a vehicle, the back can be folded down forwards or
backwards. Open the lid of the battery box (see the chapter "Removal and replacement of the
batteries"). Above the battery box on the right-hand side are bolts which can be pulled out quickly by
loosening the clasps. You have now separated the connection between the back and the frame. The
backrest can be tilted to the front or to the rear, and removed, after loosening the screw handles on
the lower side of the back unit. (The back can be fixed again by reversing this process).
ELECTRIC SEAT INCLINE (option)
If you chose the electric seat tilting option, your wheelchair will have been fitted with the system before
delivery. To operate this, it is only necessary to switch the steering unit on. The driving program then
switches itself on. If you want to adjust the angle of your seat, you just need to use the function button
for adjusting the seat. The control indicator on the DX control unit shows that you have selected this

function (on the G90 control unit, the selected symbol flashes). You can then adjust the slope of the
seat by pushing the joystick forwards or pulling it backwards.
LMake sure that no objects and/or persons are inside the swinging range of the wheelchair,
either in front or at the rear, since this could cause damage and/or injury.
LFor your safety this adjust function can only be activated when all four wheels of the
wheelchair are standing still. When this function is selected, the driving program is disabled.
ELECTRIC BACK ADJUSTMENT (option)
The back can be adjusted in a similar way to the seat angle. You only have to select button the
relevant button on the steering unit and you can then tilt the back as you wish.
LMake sure that no objects and/or persons are inside the swinging range of the wheelchair,
either in front or at the rear, since this could cause damage and/or injury.
LFor your safety this function can only be used when all four wheels of the wheelchair are
standing still. When this function is selected, the driving program is disabled.
LMake sure that you do not set the backrest too far over backwards, since this can displace the
centre of gravity too far to the back and cause tipping over.
LFor your own safety you should not drive the wheelchair in an inclined or tilted position, since it
would severely limit your visibility.
LEG SUPPORTS
The basic model of your electric wheelchair is equipped with leg supports which allow your legs to rest
comfortably. You can adjust the length of the foot supports continuously, turn them aside, or even
remove them completely. These adjustments should be carried out by a third person with the required
technical knowledge. Consult your specialist dealer if these adjustments become necessary. If you
want to carry out these adjustments yourself, you should read the following sections carefully.
When you want to fix the footrests, hang one leg support sideways on the outside and then turn it
inwards until it stops. The fixing lever (Figure B) must point backwards. If the leg supports do not
engage immediately, push them lightly inwards. Do the same on the other side. To remove the
footrests, reverse this process.
LWhen handling the leg supports, make sure that you hold on to the upper curve to prevent
your fingers from getting caught and hurt.
Turn the footplates out of the way for climbing in and out comfortably. The footplates are designed for
resting your feet securely on them; in addition, your feet are prevented from moving sideways
unnecessarily. Use the Allen keys provided to adjust the length of the leg supports. There is a
countersunk Allen screw (Figure A) on the rear side of the leg support for fixing the footplate. By
loosening this screw the footplate can be adjusted to the length of your leg. It must be tightened
properly afterwards.

LMake sure that the footplate is at least 6 cm above the ground to avoid scraping the ground
when moving. This could damage the wheelchair and endanger its operational safety. The
user might also get hurt.
LDo not stand on the footplates; they are only designed for letting your feet rest on
them.
LWhen the leg supports are adjusted, no persons or parts should be within their reach,
otherwise there is danger of injury and/or damage.
If there are patterns of illness and/or disabilities which mean there is no guarantee that your legs
would rest constantly on the leg supports, you may select from other available leg supports. Kindly ask
your specialist dealer if you have queries in this regard.
ARMRESTS The height of the armrests can be adjusted by
loosening screw (1) and pulling the armrest
upwards.
To adjust the width between the armrests, you only
have to loosen screw (2) and place the armrest in
the desired position. The screw must be tightened
properly afterwards.
LMake sure that all fixing screws are properly
tightened before using the wheelchair,
otherwise injury and/or damage can be
caused.
LNever pick the wheelchair up for transportation by grasping the armrests, but take hold of solid
frame parts only.
The armrest containing the steering electronics can only be detached if the electronics have been
removed previously.
LThe armrests may only be removed when there is no chance of the wheelchair user
falling out sideways.
If changes, damage, or wear of the suspension are noticeable, kindly consult your specialist dealer
who can remedy these defects.
LTo avoid endangering your safety, do not use the wheelchair if you see that the mountings have
changed, been damaged, or have worn out.
LIf you make any changes to the armrests and/or the armrest retainers, you do so entirely at
your own risk. Then your insurance claims lapse immediately.

CHARGING THE BATTERIES
As the IMPULSE S (8 A) charger aligns the charge curve with the AGM batteries' charge level, you
can recharge your wheelchair after each use. This avoids any aggressive battery charging and the
"memory effect".
Recharge the wheelchair, at the latest, when the charge indicator on the steering unit goes into the red
zone. If, despite this, you continue driving, eventually only the last red diode lights up and flashes
continually, indicating that the batteries are nearly flat. If you disregard this warning signal, too, an
error message will shortly appear indicating that the batteries can no longer provide power for driving.
The batteries should therefore be charged before these error messages appear, using the supplied
battery charger IMPULSE S (8 A). Avoid the batteries becoming drained, in any case.
•SETTING UP THE CHARGER
When setting up the charger, ensure that it is well-ventilated on all sides. A minimum of 10 cm space
should be left free around the unit for this purpose. If the charger is insufficiently ventilated so that the
unit heats up, the charging rate will fall which will extend the charging time. If the charger overheats (>
+50° C), it will stop charging.
The charger should only be used from a wall socket with a voltage of 230V – 50/60Hz and in well-
ventilated, dry areas.
•FIRST USE
First put the plug into the wall socket. After an LED combination has lit up, the charger switches to
STANDBY. Both LEDs (green and yellow) are active.
Next, connect the charger cable with the three-pin plug to the loader socket on the electric
wheelchair's steering unit. Once connected to the batteries, the charger automatically begins charging.
Now only the yellow LED is active.
When charging is complete, the yellow LED goes out and the green LED comes on. Now remove the
charger cable from the steering unit. The charger switches back to STAND-BY mode (yellow and
green LEDs active).
If the charger cable is not removed, a tiny current will keep the batteries topped up (trickle charging).
LWhen charging is complete, always remove the plug from the steering unit first and only then
the mains plug from the wall socket.

If you decide not to use your electric wheelchair for an appreciable period, you must nevertheless
recharge it regularly to keep it in a running condition ready for immediate use.
LIf the batteries are not used for an appreciable period, they discharge slowly by themselves
(drainage). Then it becomes impossible to recharge them with the battery charger supplied.
So charge the batteries at least once a month even if they are not being used.
LOnly use the battery charger supplied to charge the batteries.
LThe manufacturer accepts no liability for damage caused by improper charging.
LNever interrupt the charging cycle. The charger shows when the charging cycle is finished.
(green LED remains active).
For further information, please refer to the user instructions provided with the charger.
BATTERIES
The standard for your electric wheelchair is two closed, 12V/70Ah AGM batteries. The batteries used
with your electric wheelchair are drive batteries which only attain full capacity after a few charging and
use cycles.
If the batteries lose their power after long usage, or if they are damaged, get them both replaced by a
specialist dealer only.
LWe accept no liability for damage caused through using other types of battery.
LDo not use the batteries at temperatures below +5°C or above +50°C (the ideal is: +20°C).
LIf the batteries are opened, all manufacturer liability and all claims will become void.
REMOVAL AND REPLACEMENT OF THE BATTERIES
Kindly obey the following instructions when removing the batteries for servicing or for transportation:
Pull up the knobs (1) and pull the battery drawer
backwards. Now you can grasp the first battery by its
handle and pull it backwards on the rail. Then you can
lift the first battery out of the wheelchair by means of
the handgrip on the battery box. To remove the
second battery box, push your hand beneath the
battery box. There is a hollow which allows you to
take hold of the battery box from below and pull it
backwards with a slight upwards motion.
Now this battery box can also be lifted out of the wheelchair by grasping the handle. When replacing
the battery boxes, you reverse the process and only need to push the battery boxes backwards.
LTo avoid bruising, make sure that your hands are not caught between the handle and the
frame tube when battery boxes are pulled out.
LMake sure that the batteries are safely put down outside the wheelchair.
LWhen replacing the batteries, make sure that they are positioned correctly and that the plugs
on the battery boxes are on the left side.
LBoth connectors of the battery boxes, one at the front and the other at the rear, must be
plugged in first, otherwise there is no connection to the electronics.
LMake sure that the plugs are connected properly after replacing the battery boxes. If the rear
cover does not fit over the knobs (1), it means that the plugs have not connected properly.
When transporting the wheelchair, it is not necessary to remove the batteries from their boxes. When
removal of the batteries becomes necessary (e.g. replacing the batteries), note the following:
•Remove the battery box lid by loosening the screws on the handle.
•Lift the lid off.

•Put the handle back on the battery to allow it to be carried.
•On one side the battery box is connected to the battery by an Allen screw. Unscrew this and
remove it.
•The battery can be lifted out of the battery box by the handle after the pole clamps have been
removed.
•Reverse these processes when replacing the batteries.
LThese tasks should be undertaken by the specialist dealer.
LMake sure that no tools or other conducting objects make contact with both poles of the
batteries, or the resulting electric currents can cause injuries.
LNo work involving the batteries and the electronics should be undertaken in damp conditions.
LWhen connecting the batteries, you should consult the circuit diagram on the battery box lid.
LThe manufacturer is not liable for damage/injury caused by improper handling.
BATTERY CONNECTIONS
BATTERY STORAGE
If you do not use your wheelchair for a long while, you can leave it connected to the battery charger.
Charging is automatically controlled by the battery charger. If you remove and store the batteries,
kindly note the following:
•Remove the cable clamps from the poles of the battery.
•The positive pole must be covered by at least one pole cap.
•Only grasp the batteries by two opposite sides of the unit.
•Ensure no objects get in between the poles (a short-circuit could occur!).
•Batteries should only be stored in dry, well-ventilated spaces at a temperature between +5°C and
+45°C.
•Leave batteries in their battery boxes so they are protected from damp, etc.
•Protect the plugs and sockets of the battery boxes against corrosion.
•Protect the batteries against drainage (see "Charging the batteries" section).
LIf batteries are not used, they can completely drain.
Your dealer will be happy to advise you on storage and with inspecting your batteries.
THERMAL FUSES
To protect the motor against overload, on the right side of the seat frame there is a thermal fuse that
will automatically cut off the motor to prevent overheating and thus rapid wear and tear or
breakdowns. This can occur if you go up or down slopes that exceed the maximum gradient indicated.
Nominal loads exceeding the maximum could also trigger the safety mechanism. If you try to drive
with the brakes on, it could also result in overload. The values to comply with are indicated in the
“Technical Details” section. To be able to use the wheelchair again, remove the overload and wait till
the motor has cooled off, and then gently press in the thermal fuse again. The system is now ready for
use again.

PARKING BRAKES
In addition to electromagnetic braking, your electric wheelchair can also be equipped with fixed
braking for each driving wheel. These must then be set for the wheels. When pneumatic tyres are
used, the parking brake can only function when the tyres are inflated hard enough (see the section
"Technical details").
LNote that the tyre pressure should always correspond to the values given in the section "Technical
details", otherwise the action of the parking brakes would be reduced or even be zero.
LNote that the parking brakes are not supposed to be used for braking while driving. The real
function of the parking brakes is to prevent the wheelchair from rolling away after it has
stopped. If it is used for reducing the speed while driving, injury and/or damage could result.
If the brakes lose their function through wear and tear and/or the covers and hoses have been
damaged, we advise you to consult your specialist dealer who has the tools and the knowledge for
repairing / replacing the defective parts.
LWhen unsuitable tools are used or through improper maintenance
damage and/or loss of function could result.
If you wish to adjust the parking brakes yourself, use a suitable Allen key to loosen the two screws
which hold the brake suspension on the rail. Then push the brake unit to the desired position and
retighten the two Allen screws and check whether the braking action is correct.
LBrake adjustments not complying with the manufacturer's instructions are done at your own
risk (only in the case of built-in parking brakes). No liability is applicable.
LRather let your dealer adjust the parking brakes; he is trained on our products and will comply
with all relevant prescribed safety measures.
LNote that the parking brakes are not supposed to be used for braking while driving. The real
function of the parking brakes is to prevent the wheelchair from rolling away after it has
stopped. If it is used for reducing the driving speed, injuries could follow.
If you are not satisfied with the braking behaviour of your wheelchair, consult your specialist dealer
immediately; he will then adjust the brakes properly.
LIf water, oil, or other kinds of dirt have soiled the wheels of the wheelchair, then the braking
action of the parking brakes would be impaired. Check the condition of the wheels every time
before using the wheelchair.
LIf the brakes lose their effectiveness because of wear and tear and/or damage to the
tyres/inner tubes, kindly consult your specialist dealer, since special machines are required for
changing the "PU" tyres. The end-user is not able to change the "PU" tyres.
TYRES
The TRACER electric wheelchair is fitted with 3.00-8 driving wheels (standard pneumatic) and 260x85
steering wheels (standard pneumatic). Consult your specialist dealer about other wheel combinations.
He will advise you as to which combinations are suitable for your individual requirements.
LMake sure that the wheels are always inflated correctly, otherwise the driving behaviour might
be affected. The correct pressures for the tyres are given in the chapter "Technical details". In
addition, you should always check the pressure values appearing on the tyres themselves.
LWe do not provide any guarantee for wheels not supplied by the manufacturer.
TYRE CHANGING
If you want to change the tyres or inner tubes, you should note the following:
Before you can remove a tyre, you must let all the air out of the tube, and insert a tyre lever between
the tyre and the rim. Then slowly and carefully push the lever downwards. This will pull the tyre over
the edge of the rim. If you then move the lever along the rim, the tyre will jump out. Now carefully
remove the tyre from the rim and then remove the tube.
LThere must be no air in the tube before it can be removed.

LIf handled improperly, the rim might be damaged. We recommend you get your dealer to do
this work.
Note the following before inserting the new inner tube:
Check the rim bed and the inside wall of the tyre for foreign matter and clean these properly if
necessary. Check the condition of the rim bed, especially around the position of the air valve. Please
use only genuine original replacement parts. No liability is accepted for damage caused by non-
genuine replacement parts. Kindly contact your specialist dealer.
WHEN PLASTIC RIMS ARE USED
Place the rim belt in position over the air valve before
inserting it into the rim. Then the rim belt can be pulled
over easily. Check whether all spoke heads are
covered (in the case of a plastic rim a rim belt is not
required).
Push the tyre over the edge of the rim, starting behind
the air valve. Inflate the tube slightly until it is round,
and place it inside the tyre.
If the inner tube fits snugly inside the tyre without any
folds (if there are folds, let some air out), then you can
push the upper side of the tyre gently onto the rim with
both hands, beginning behind the airvalve.
Check all around on both sides that the tube is not pinched between the rim and the edge of the tyre.
Lightly push the air valve inwards and pull it out again to make sure that the tyre is positioned properly
in the region of the air valve.
To ensure that the wheel is inflated correctly, admit only so much air initially that the tyre can still be
easily pushed inwards by using your thumbs. If the check-lines are equidistant from the edge of the
rim on both sides of the tyre, then the tyre is centered properly. If not - let out the air and position the
tyre afresh.
Now the tyre can be inflated to its full operating pressure (note the maximum) and the valve cap
should be replaced.
