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").
L Note 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.
L Note 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.
L When 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.
L Brake 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.
L Rather let your dealer adjust the parking brakes; he is trained on our products and will comply
with all relevant prescribed safety measures.
L Note 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.
L If 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.
L If 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.
L Make 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.
L We 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.
L There must be no air in the tube before it can be removed.
