Maintenance Intervals; Scopes Of Maintenance; Repair; Inner Tube/Rim Tape/Tyre Replacement - Otto Bock Voyager Evo Instructions For Use Manual

• Failure to maintain the product can lead to serious or life-threatening injury to the user of the product.
• Service and repairs may only be carried out by authorised dealers or the manufacturer. This will ensure that
only Ottobock spare parts are used for repairs.

7.1.1 Maintenance intervals

The functions described below must be checked by the user or an attendant at the specified intervals:
Inspection task
Functional test of the wheel locks
Footplate stability
Visual inspection of wear parts (e.g. tyres, bearings)
Soiling of bearings
Damage to the push ring
Air pressure (printed on the tyre sidewall)
Wear to the folding mechanism of the backrest
Check of the spoke tension on the rear wheels
Check of all bolted connections

7.1.2 Scopes of maintenance

To ensure smooth operation at all times, users or attendants with some technical skills can maintain some parts of
the wheelchair:
• Hair and dirt frequently collect between the caster fork and the caster wheel and make the caster wheels
harder to manoeuvre as time goes by. Remove the caster wheel and thoroughly clean the fork and caster wheel
using a mild household cleaner.
CAUTION: In order to avoid impairing the tip resistance of the product, the caster wheel journal angle
must not be changed during this process.
• The rear wheels are equipped with quick-release axles. To keep this system operational, ensure that no dirt
adheres to the quick-release axle or axle housing. Periodically lubricate the quick-release axle very lightly with
resin-free sewing machine oil.
• If the wheelchair becomes wet, it should be rubbed dry again.
• Bolted connections must be periodically checked for tightness, especially during the initial period of use or
after adjustments have been made to the wheelchair. If a screw connection loosens repeatedly, contact the
specialist dealer promptly.

7.2 Repair

7.2.1 Inner tube/rim tape/tyre replacement

INFORMATION
When driving outdoors, always carry a repair kit and tyre pump (when using pneumatic tyres) in case of emer­
gency.
Suitable tyre pumps are listed on the order form and are supplied with the product. An alternative is tyre foam,
which fills your tyre and then hardens (available from bicycle shops etc.).
Repairing flat tyres requires only the necessary tools and minimal technical skills. Users may change tyres them­
selves if they wish:
Removal and Preparing for Installation
1) Carefully remove the tyre from the rim using appropriate tools.
INFORMATION: Take care not to damage the rim or the inner tube.
2) Unscrew the valve nut from the valve and remove the tube.
3) Repair the tube according to the directions in the repair kit or replace it with a new tube.
4) Before fitting the tyre again, inspect the rim bed and tyre inner wall for foreign objects. This could have caused
the puncture.
5) Before installing the tube, check that the rim band is in proper condition. The rim band protects the tube from
being damaged by the ends of the spokes.
