1 Introduction

1.1 Foreword

Regular maintenance is important – it improves safety and increases the lifespan of the product.

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

However, we recommend inspecting, readjusting, and if necessary servicing the product every 6 months if the product

is used frequently, by growing children, or by patients with changing clinical pictures.

Only use original spare parts for all service and maintenance work. The service and maintenance tasks described here

should only be completed by trained, qualified personnel and not by the user of the device.

This service and maintenance manual refers to the respective spare parts catalogues and the instructions for use of

the described products. Please use these documents together.

Use the maintenance schedule (checklist) as a template for making copies. Retain completed maintenance schedules

and provide the customer with a copy.

3.3 Special features of the Avantgarde CLT

Lightweight construction was strictly applied in the design of the Avantgarde CLT ultra-light active wheelchair. This

necessitates the greatest possible care during adjustment.

In particular the tightening torques for the bolts of high-strength aluminium alloy must be strictly observed (see table).

Before re-assembly and re-use of the aluminium bolts, inspect the threads for damage. We recommend that new alu

minium bolts are used at each (re-)assembly.

Use a liquid bolt locking compound on the aluminium bolts (e.g. Loctite 241®).

personnel) – order number 647G585.

3.12.2 Replacing the Knee Lever Wheel Lock

CAUTION

Inadequate braking function of the knee lever wheel lock

Risk of accidents, falling

►Check the air pressure of the rear wheels and the correct setting of the knee lever wheel lock. The correct air

pressure is printed on the sidewall of the tyre. For rear wheels, the minimum air pressure is 7 bar.

►Use only original rear wheels with a tested out-of-round of 1mm maximum.

1) Unscrew/remove the Allen head screws in the slide block on the bottom of the frame (see Fig. 149).

2) Carefully remove/replace the knee lever wheel lock from the slide block (see Fig. 150).

3) Position the knee lever wheel lock in place on the slide block and bolt down – do not tighten.

4) Adjust the knee lever wheel lock. The clearance between the tyres and the brake block when the wheel lock is not

actuated must be max. 5mm (see Fig. 151).

5) Tighten the Allen head screws to 6Nm.

→After adjustment, the left and right knee lever wheel lock must have the same braking effect.

2) Install the rotation prevention.

3) Pre-install the mounting plate with fitting on the rear wheel adapter – do not tighten.

4) Insert the supplied spacer bushing between the mounting plate and the rotation prevention.

5) Connect the mounting plate and rotation prevention.

6) Install the mounting plate tightly on the fitting. Secure the hex nuts (size 24) with high-strength thread locker

(Loctite® 601). The proper tightening torque of the screw connection on the fitting is 50Nm on each side.

Installing the brake handles / Bowden cables

1) Install the brake handles on the back tubes (Phillips head screws; Retrofitting the Drum Brake [], similar to figure).

can develop.

3) Connect the Bowden cables to the brake drums.

4) Install the rear wheels and readjust the Bowden cables if necessary.

5) The maximum braking force should be attained within the first third of the brake lever travel.

155 156

3.12.6 Adjusting the Drum Brake

The braking force can be adjusted via the adjusting nut (see Fig. 157, item 1).

• Turning the adjusting screw out: the braking force is increased.

• Turning the adjusting screw in: the braking force is decreased.

1) Turn the adjusting screw out until friction noise can be heard when the wheel is turned.

2) Turn the adjusting screw in until the friction noise disappears. Then the wheel should turn freely.

3) Secure the adjusting screw by tightening the lock nut (see Fig. 157, item 2).

INFORMATION

Note that the drum brake shows sufficient braking force only when the manual brake lever is locked in the 2nd ratchet

position.

INFORMATION

Ensure that the braking force of both rear wheels is adjusted equally.
