Slacken the two Pivot Screws 

“A”

 in 

Figure 32

. Tilt the backrest forwards or backwards to the 

new position as shown in 

Figure 33 

and re-tighten both Pivot Screws. 

Note: 

When making any adjustment involving rotation of the arms, 
ensure the 

Locking Levers

 are in the 

Unlocked

 

position so 

they can rotate freely within the Mounting Blocks. 

 

 

 

The seat depth can be reduced  

(Figure 35) 

by rotating the 

Mounting Blocks so that they 
move from the standard position 
(at an angle, behind the back 
canes) until they are at the 
maximum forward position, in 
front of the back canes and 
parallel with each other. Any 
intermediate position can be 
selected. 
 

The seat depth can be further 
reduced 

(Figure 36) 

by rotating the 

V-Trak Arms forwards to move the 
backrest further forward over the 
wheelchair seat. Use the Locking 
Cams to secure the final position.
