Oiling the removable axles
To ensure the proper function of the removable axles, they must
be oiled at regular intervals.
Pour some resin-free bicycle oil on a cloth and slightly oil the
balls at the end of the removable axles, the axle and the
push-button.
Checking the bolted connections
Bolted connections may loosen if the wheelchair is used
frequently.
Check the bolts monthly for tight fit, re-tighten, if necessary.
Locknuts and locking bolts should be replaced if they
become loose.
For replacement please contact an authorized dealer.
Repairing or replacing tires
Take off the wheel (see Chapter 3.2).
Deflate the tire by pressing on the valve.
Lift one flank of the tire off the wheel rim.
Use a bicycle tire lever for this. Do not use sharp or pointed
objects such as screw drivers in order to prevent the inner tube
from being damaged.
Pull the tube out of the tire.
Repair the tube using a bicycle tire repair kit. If repairing is
not possible, replace the tube.
Fitting tires
Inflate the tube slightly until it has its round shape.
Insert the valve in the valve hole of the wheel rim and insert
the tube in the tire (the tube should be inside the tire
completely without folds).
Starting at the valve push the tire flanks over the edge of the
wheel rim with both hands. Make sure that the tube is not
jammed between the tire and the wheel rim.
Use a bicycle tire lever for this. Do not use sharp or pointed
objects such as screw drivers in order to prevent the inner tube
from being damaged.
Pump the tire up to the maximum operating pressure. Make
sure that the tire does not loose air anymore.
Spare parts
All spare parts are available at your authorized dealer.
To determine the size of a front wheel compare its outer
diameter to the scale on the back of this manual.
