6.8 Wheel alignment
Adjusting the wheel alignment
NOTE: To achieve the very best movement, the rear wheels must be
adjusted to their optimum position, which means correctly adjusting the
wheel alignment. To do this, measure the distance between both
wheels front and rear to ensure that they are parallel to one another.
The difference between both measurements should not exceed 5 mm.
The parallel setting can be adjusted by loosening the screws, (1) and
rotating the axle adapter (3).
When finished, make sure that all screws have been properly
tightened, (Fig.6.8.1 to Fig.6.8.2). Re-tighten the Allen screws to 8 Nm.
WARNING!
Be careful, there is a risk of tipping when adjusting the centre of gravity
of the seat!
Adjusting the rear wheelbase width
The rear wheelbase is defined as the distance between the upper side
of the rear wheels and the backrest tubes and is factory set, (125 mm).
This must be increased if more space is to be created between the
tyres and the optional height-adjustable armrests.
When adjusting the rear wheelbase:
• Move the axle adapter (3), in a telescopic manner into the axle
bracket (2), or out of the axle bracket.
• Loosen the Allen screw, (1), on the rear of the axle bracket.
• Move the axle adapter, (3), in or out, until the desired wheelbase is
achieved.
• Re-tighten the Allen screws (1), using a two-stage process:
a) Tighten both Allen screws to a torque of 5 Nm.
b) Tighten both Allen screws for a second time to a torque of 8 Nm.
•
Repeat the procedure on the right side of the wheelchair setting
the gap the same as for the left side, (Fig.6.8.1 to Fig.6.8.2).
CAUTION!
• When adjusting the rear wheelbase, set first one wheel and then the
other.
• Wheel alignment needs to be checked and, if necessary, adjusted
after the axle adapter was moved or removed (please refer to section,
("wheel alignment").
• Loctite ™ 243 thread-locker MUST be used for re-mounting the Allen
screws (1) on the axle-adapter.
