[Easy repairs]
The rubber covers "a" at the centers of the wheels can
be installed easily without tools. If the rubber covers are
damaged or lost, contact the dealer for replacements. If
you continue to use the NAVIGO when these parts are
damaged or not installed, dust or water could enter the
unit and cause it to malfunction.
When new parts are installed, ensure that they are in-
stalled securely and operate correctly before using the
wheelchair.
To purchase a new battery, contact the dealer.
[Normal repairs]
If other parts are damaged or lost, immediately contact the dealer. Have the dealer replace the parts
or repair the wheelchair.
For normal maintenance, repairs, or service, be sure to contact the dealer. The user should not re-
pair or service the wheelchair, or remove, pack, and send the parts to request repairs. If the wheel-
chair is not repaired or assembled completely, the user or those around the user could be injured.
To perform repairs and service, the dealer uses the service manual, parts catalog, and other docu-
mentation. These items are not sold to the general public.
When requesting repairs, do not send the wheelchair directly. First, contact the dealer.
In addition, a substitute wheelchair will not be provided during repairs or inspections.
You must pay for repairs that are not covered by the warranty.
