Technical Information
2.13 Drive wheels
With HD Motion model 22 drive wheels of size 20”, 22”, and 24” can be used, together with different tyre
types. 22” is the standard size, all reference measurements and tests are based on this standard.
The size of drive wheels, tyre type, wheel mounting position, and camber angle all affect the driving
characteristics of the wheelchair, as well as general characteristic such as length and total width.
2.14 Tip protectors
HD Motion is equipped with tip protectors, see Figure 12. The tip protectors are fixed in placed and
cannot be removed without tools. By pushing inward with a foot or hand the tip protector can be
turned up to an inactive position. The attachment for the wheel (6) can be adjusted to different
positions with a snap lock (5) to give the desired tip protection. The same tip protectors are used for
HD Motion 22 and HD Motion 16.
If the entire tip protector is to be replaced remove the screw (8) from the underside of the wheel frame.
NOTE
: When assembling a new tip protector the spring washer (7) must be oriented correctly, with the
convex side facing upward.
NOTE
: The tip protectors have left-hand and right-hand versions.
If HD Motion 22 is equipped with a different
wheel size than the standard 22” the tip
protectors need to be modified as follows:
20” drive wheels
:
The tip protector can be retained, but
to keep the same setting options the
tip protector tube (4) is replaced with a
shorter version as follows:
1. Remove the screws and nuts (1).
2. Replace the tube (4).
3. Re-assemble the screws and nuts.
4. Move the wheel attachment (6) to
the new tip protector.
24” drive wheels
:
Replace the wheel attachment (6) with a
longer version. This compensates for the
height difference to the ground.
NOTE
: If the wheel attachment is not replaced
the tip protector will not be as safe in all
positions as it is in the standard configuration.
