1 Introduction

1.1. Preface

Regular maintenance is important. It increases safety and prolongs the service life of the prod-

uct.

All Mobility products should be inspected and serviced once a year.

However, if the product is used frequently, or if it is used by growing children or patients with

changing clinical conditions, we recommend readjusting and servicing the product every 6

months.

Use only original spare parts for all service and maintenance.

The service and maintenance described in this manual should be performed by trained spe-

cialists only and not by the user.

This service and maintenance manual refers to the spare parts catalogs and instructions for

use manuals for the products described. For this reason, it is important to use these docu-

ments together.

Use the maintenance plan (check list) as a template for making copies. Retain completed main-

tenance plans and provide the customer with a copy.

Attention!

Clean or disinfect the product before starting inspection. See the instructions for use manual

for care instructions or specific product inspection information.

Many of the screw fastenings use thread lock or nylock nuts. If you have to undo such

screw fastenings, replace the nut or screw with a new nut/screw with thread lock. If new

screws or nuts with thread lock are not available, use a medium-strength liquid thread lock

substance (such as Loctite 241 or Euro Lock A24.20).

First remove the rear wheels by pressing the button of the quick-release axle with your

thumb and pulling off the wheel (Fig. 1). Fully loosen the two screws on the front of the

rear wheel attachment (Fig. 2) and remove them. Now pull the U-shaped section off to the

rear.

Slide the pre-assembled anti-tipper onto the rear wheel axle, which is now freely acces-

sible, past the rear wheel adapter, until the (hexagonal) attachment of the anti-tipper is

located on the hexagon of the axle (Fig. 3).

Fix the anti-tipper using the clamping screw (Fig. 4) and test the swing-away and locking

function.

Reinstall the rear wheel attachment and attach the wheels by repeating the steps described

above in the reverse sequence.
