6 Adjustment / Assembly Instructions

All wheelchair users have expectations regarding wheelchair type, accessories, seating and
handling.
Your Start wheelchair has many options by which it can be customized to your needs and prefe-
rences. We recommend consulting with your dealer or therapist to determine which wheelchair
settings will work best for you.
INFORMATION!
The following tools are required for repair and maintenance:
• Allen wrenches, sizes 4 and 5 mm
• Torx Allen wrenches, sizes x 30
• Open-end wrenches, sizes 19 and 24 mm
• Socket wrenches, sizes 10 and 19 mm
• Phillips head screwdriver

6.1. Adjusting seat height and seat inclination
The higher the rear wheel is attached to the frame, the more the seat inclines downward. This
positions the user deeper and more firmly into the seat. However, rear wheels that are attached
high at the frame also make the wheelchair more prone to tilt backwards. A careful and syn-
chronized height adjustment of both the rear wheels and the casters will allow to adapt the seat
height to the user's individual requirements.
INFORMATION!
Please note: When the rear wheel position is changed, the angle of the caster axle
in relation to the ground also changes. Ensure that this angle is always approx. 90°
wide (see "Caster wheels"). The wheel lock must be re-adjusted as well (see "Wheel
lock") .
INFORMATION!
The Start M1 Intro, M2 Effect, M3 Hemi and M6 Junior offer the possibility to change
the vertical position of the rear wheel by shifting the rear wheel adapter along the
frame. Loosen the two screw connections A (Fig. 24) and remove the screws. Shift
the adapter to the desired position and firmly retighten the screws.
INFORMATION!
Make sure to firmly retighten all screws and nuts after making adjustments. The pro-
per torque for the screw connection of the rear wheel adapter is 8 Nm. The proper
torque for the screw connection of the fitting is 50 Nm.
For Start M4 XXL and M5 Comfort: Loosen the nut A (Fig. 25) of the quick-release
axle housing on the inside of the frame and remount the axle housing at the desired
position. The proper torque is 50 Nm. The distance between rear wheel and side
panel can be continuously adjusted by adjusting the counter nut on the outer side
of the frame.
