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.
•

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”).

if the other person helps or not.
Drive the wheelchair as close to the bed as possible and ensure, that front wheels are facing towards
Pull the brake, lift the footrests.
Do not climb the footrests, it can cause falling over the wheelchair.
The attendants should use mainly the strength of muscles of legs to draw the wheelchair on stairs
avoiding the excessive bending down and impairing the muscles of backs.
Riding the wheelchair
The correct weight distribution is a basic element of the proper wheelchair usage. The correct
wheelchair operation depends not only on the weight but also on the body constitution, position of
the person seating on the wheelchair and location of the rear wheels of the chair. The larger weight
proportion of the passenger rests on the rear wheels of the chair the easier to drive it. The larger
weight proportion of the passenger rests on the front wheels the harder to drive the wheelchair.
Attendants: They should ensure, that the brake is always applied, when they are going away from
the wheelchair with the passenger seating on it.
Parking: One ought to ensure, that the front turning wheels are always pointing forwards, when the
wheelchair is not in movement, to enlarge their contact with the base.
How to ride over the kerb?
Passenger turned with face to the obstacle
(We advise, to use the below mentioned technique only by the experienced
wheelchair users.)
Drive the wheelchair as close to the kerb as possible
Incline the wheelchair backwards balancing on the rear wheels and lift the
front turning wheels to the height of the kerb. Push the rear wheels forwards
and in the same time lean over transferring the weight to the front of the
wheelchair.
Attendant and passenger turned with their faces to the obstacle
The attendant inclines the wheelchair backwards with use of the bar for
inclining, so that the front turning wheels appear on the side-walk.
Use the handles at the back of the wheelchair to enter the rear wheels on the
side-walk.
Passenger turned to the obstacle with their backs
(The below mentioned technique will give the results only in case of the very
low obstacle and when the height of the footrests is sufficient to not make the
obstacle.)
Drive to the obstacle backwards so as the rear wheels will touch it push the
rear wheels backwards leaning in the same time forwards.

weight of single parts. It is possible to detach rear wheels, footrests and fold the chair's cross frame
very easily, in the way that was described previously
Car transport
Fold and place the wheelchair in the car trunk. If, for some reason, it
is not possible, put the folded wheelchair between the front and the
rear seats inside the car ensuring that the wheelchair is in a sure and

Parts, which should be regularly inspected:
Part name Control type Control frequency
Tires Tire pressure (2,0-2,2 bar), condition of tread and tires. One
should take care, to keep the pressure in both tires on the
same level. Harder tires provide better manoeuvrability of
the wheelchair and easiness of driving, but they reduce the
comfort on bumpy surface.
At least once a week
Spokes Loose spokes can cause deformation of the rear wheels.
Contact your dealer or local bicycle service to manage the
problem of loose spokes.
If the problem occurs
Wheel axles Remove the hair or accumulated dirt If necessary
Push Rims Excessively scratched push rims ought to be exchanged
because they can wound the user’s hands during riding the
wheelchair
If necessary
Brakes The braking force depends on the tyre pressure. The
efficiency of brake operation can be also affected with dirt
accumulated on tyres. Keep the brakes clean wiping them
with a damp cloth to remove dirt, and also lubricating the
funnel of screws, on which the brake levers turn.
Control the correctness
of brake operation at
least once a week
Frame Keep the wheelchair clean for better comfort of the user. At least once a month,
depending on usage
conditions
Turning
wheels
The area between the fork and the front wheel should be
kept clean, because of dirt accumulating there, which can
cause faster wear of turning wheel bearings. To do so, one
should disassemble the front wheel by unscrewing it from
the fork, remove all dirt, and then preserve the metal
elements of the wheel (i.e. technical grease).
The maintenance ought
to be made once a
month or more often
depending on usual
surface type &
conditions
Detachable
elements
Check condition of detachable elements of the wheelchair, if
screws are loosen they should be tighten.
In case of intensive
exploitation of the
wheelchair the
inspection should be
carry out once a
month.
Quick-release
axles of the
rear wheels
One should clean and then lubricate lightly the quick-
release axles of the rear wheels. The slots where the quick-
release axles inserted ought to be cleaned up from all dirt
with dry cloth. The wheel should be laid on the base, resting
on the push rim (never opposite way, because the quick-
release axle can catch dirt from surface, which can cause
it's seizing in the main axle socket. In case of solid particles
occurring on the surface of the quick-release axle, usage of
such axle is not allowed.
Lubricating should be
carried out periodically.
