Centre Of Gravity; Wheel Camber; Toe-In - Meyra PROFI 3 Operating Manual

CENTRE OF GRAVITY

The adjustment should be car-
ried out by the specialist
dealer!
The centre of gravity is infinitely variable
by way of axle tube displacement.
Note!
The overturning risk increases
with a reduction in the axle
separation distance (Forward
displacement of the axle tube)!
The axle tube must be displaced in a
parallel manner for a perfect driving
behaviour. The separation distance
between axle tube and backrest tube
(Fig.27) must be the same on both
sides.
Handling:
Tools
Hexagonal stud wrench WW* 4
– Slacken the adjustment screws (A,
Fig. 28) of the axle tube.
– Slide the axle tube parallel to the
desired separation
(Fig.29).
WW* = Wrench width [mm]

WHEEL CAMBER

The adjustment should be car-
ried out by the specialist
dealer!
The wheel camber (Fig.30) can be set
to 1° or 3° by way of different axle
mount adapters.
Handling:
Tools
Hexagonal stud wrench WW* 3
– Detaching drive wheel. – Do this by
pressing in the stop knob at the centre
of the wheel and pulling off the
wheel.
– Slacken the adjustment screw (A,
Fig.31) of the tube clamp.
– Pull off the axle mount adapter.
– Insert the axle mount adapter with
the desired wheel camber in the
mounting tube.
– Lightly tighten the adjustment screw
(A).
– Attach the drive wheel (see axle ).
– Adjust toe-in (see Toe-in ).
distance
– Convert other side accordingly.
Note:
When ordering different axle mount
adapters for a wheelchair equipped
with pressure brakes it is necessary to
order the required spacers at the
same time.

TOE-IN

The adjustment should be car-
ried out by the specialist
dealer!
The toe-in can be adjusted by rotating
the mount adapter (B, Fig.31) for the
axle.
Handling:
Tools
Engineer's wrench WW* 10 and 22
Hexagonal stud wrench WW* 4
– Slightly slacken the adjustment screw
(A, Fig.31) of the tube clamp. – It
should be just possible to turn the
axle mount adapter with the open-
end spanner.
Set toe-in with attached drive wheels:
– Optically align drive wheels parallel
to the frame. – Do this by rotating the
axle mount adapters (B, Fig.31) in
the appropriate direction.
Fine adjustment:
– Adjust for equal front spacing be-
tween drive wheel and the frame
tube on both sides. – The spacing is
to be determined with, for example,
a ruler (Fig. 32).
Remark
The above only ensures that the drive
wheels are positioned equally to the
frame.
– Measure the front and rear spacing
between the drive wheels at the
same height (Fig.33).
