The footrest angle is set as standard at 14° to the horizontal. With the footrest in the lowest possible 
setting, an angle of 4° is the only practicable variation as the footrest otherwise touches the ground 
before the leg supports (hence no standing stability!). 

With the second lowest setting the only potential variations are 4° and 14°, for the same reasons. 
For all higher footrest settings there is a choice of all three angle variations.

Adjusting the gas spring release 

 
It is important to check that the gas springs respond to the gas spring release lever and lock and 
release correctly as part of the standing up. 
 

Caution: When checking the gas spring release, the gas springs should be extended, i.e. the 
wheelchair should be in a standing position! Risk of accident! 

 

•

 

If the gas springs are sluggish on release, the cable tension is not 

tight enough. Loosen the counter nut (A) using a 10 mm Allen 
key and turn the adjustment screw (B) one turn to the left using 
a 8 mm spanner (anti-clockwise). 

•

 

If the gas springs are not locking properly, the cable tension is 
too tight. Loosen the counter nut (A) and turn the adjustment 
screw (B) one turn to the right (clockwise). 

•

 

Repeat until the gas springs lock correctly.

9. Repairs 
 

9.1.  Replacing tire/inner tube of rear wheels 
 

•

 

Remove the wheel and open the valve before pressing down on 
it to let out the air (see photo 10). 

•

 

Using a bicycle tire wedge, ease both sides of the tire over the 
wheel rim and pull the inner tube out of the tire (see photo 11). 

•

 

Replace the inner tube by forcing one side of the tire back over 
the wheel rim, pump up the tire a little, ease the valve through 
into the hole and lay the inner tube along inside of the tire. Once 
the whole tube is snug inside the tire, force the other side of the 
tire back over the wheel rim (starting on the side opposite the 
valve). 

•

 

Check lest the inner tube be caught between tire and rim before 
pumping it up in line with the manufacturer’s recommended tire 
pressure (see Technical Data, section 12).
