also possible to use puncture proof tires.
The wheelchair is delivered with the standard aluminium push rims. The material and the distance
between the push rim and the wheel can influence on the grip strength of the wheelchair’s user.
One should be careful and not allow the fingers to get between spokes during driving in narrow
passages. To avoid such risk it is recommended to use a spoke protection (accessory).
WARNING!One should regularly control the pressure in tyres, which ought to be in
range of 2 – 2,2 bar depending on the weight of the user. The heavier user – the higher
pressure.
Advanced settings and adjustments
WARNING! We recommend all advanced adjustments to be done by the qualified staff
only. An inappropriate adjustment can cause deterioration of the safety usage of the
wheelchair and decrease its durability.
Main wheels position adjustment
The wheel balance on “Dolphin” chair can be additionally adjusted by moving the wheel axle. In such
case it is necessary to readjust also the position of the front, rotating castors.
To adjust the rear wheel position:
It is possible to adjust rear wheels up, down, forth and
back depending on wheel size and personal preferences
of a user. The height of wheel assembly allows to modify
the height of the wheelchair’s seat.
The horizontal adjustment (front/back) allows to influence
the stability and maneuverability of the chair. The most
common and neutral position is “B”. If it is necessary to
increase the maneuverability the wheel can be moved to
position “A”. It is easier to maneuver with wheelchair that’s
wheels are set to position ”A”, but the rearwards stability is
much lower. If the wheels are adjusted to “A” position, the
chair should always be equipped with activated anti-tip supports to protect wheelchair against
tipping over. Persons with amputated leg(s) should never use chair with wheels in position “A”. The
risk of tipping over is too high.
For users after leg(s) amputation position “C” was designed. It offer much more stability that other
positions, but even though users like that should always use chair equipped with activated anti-tip
supports to protect wheelchair against tipping over.
It is not recommended to use chair with wheels in position “C” by people who did not have any
amputation. Maneuvering with such chair might be very difficult for them.
WARNING! The correct position of wheels should be always determined by professional
therapist or wheelchair provider.
It is possible to reach 5 different height adjustments and 3 different horizontal adjustments
To adjust the height of the wheel:
• Take off the wheel by using quick release button.
• Disassemble the black wheel assembly plate by untying 4 bolts. Set the plate in to one of 5
available positions (holes 1&2, 2&3, 3&4, 4&5 or 5&6)
• Retie the bolts to secure the plate.
• Repeat above on the other side of the chair.
To adjust the horizontal position of the wheel (A, B or C)
• Take off the wheel by using quick release button.
• Unscrew the silver wheel socket mounted on black wheel assembly plate
• Relocate the socket in to desired hole (A, B or C)

Front, rotating castors with 8” wheels
The standard front wheels are 200x50 mm, made of polyurethane. We
recommend to stick to above type of wheels, but it is also possible to use
pneumatic tires. It is possible to mount different sizes of front wheels if it
is required by rear wheels position (see sheet below).
If the vertical position of rear wheels was modified it is necessary to
adjust the front castors position accordingly. The vertical turning
axle of the castor should always be in position of 90 (+/- 2°) degrees to
the floor. It is possible to adjust it by turning the acentric (1) bolt
until the required position is reached.
If the setting range has to be larger it might be necessary to change the
wheel position between holes (A, B, C, D) by unscrewing bolt (2) moving
the wheel up or down to needed height and tying the bolt (2) back.
In some situations it is needed to replace the standard front wheel (8”)
with the wheel of another size (6” or 7”).
