Protection against corrosion
The Duet is coated in a way that the metal parts of the wheelchair are protected for
corrosion. The material of all other parts, like the mud shields, rims etc. is not susceptible to
corrosion.
It is however advised to clean the Duet with soft soap and warm water when it has been
exposed to unfriendly circumstances like mud, salt water or severe rains. After removal of the
dirt and salt, please dry the wheelchair with a soft cloth.
Brakes and gears
The rear brake is of the back pedalling type and cannot be adjusted. Please check the
tolerance of the chain frequently (e.g. each month). Too much clearance leads to unwanted
late reaction of the brake (while back pedalling, the clearance of the chain has to be over
won).
The used cables for the front brakes have to be re-adjusted from time to time. Re-adjusting
the brake can be done by tightening or loosening the shown adjustment bolt. The adjustment
must be so that the lever has a very small free play before pulling the inner cable. When
applying maximum brake force, the brake bar may not be obstructed by the steering
Adjustment of the gear cable must be carried out by a therefore trained person such as your
dealer.
Replacement of worn brake friction material must be carried out by an authorized dealer.
