4.1 Foreword

Periodic servicing is important as it increases safety and extends the product’s service

life.

Every rehabilitation product needs to be inspected and serviced on a yearly basis.

We recommend to inspect, adjust, and, if necessary, service a product every six

months if the product’s users change frequently (children and young people growing

up), or when the user’s clinical picture is subject to changes.

Use only original spare parts for all service and maintenance work.

Service and maintenance work must only be performed by appropriate expert

personnel!

The service instructions refer to the spare-parts catalogue, and to the operating

instructions. All the documents should be used together.

4.2 General safety instructions

Please observe the following principles during all servicing and repair work:

- Read the service and maintenance instructions carefully before you start any work.

- Familiarize yourself with the product’s functions. If you do not know the product, you

should study the operating instructions carefully before you begin with the

inspection.

The operating instructions can be obtained from the manufacturer (see the list

of Otto Bock’s branch offices in „Otto Bock Worldwide“).

- You can also download the documents from our home page:

www.ottobock.de or www.ottobock.com.

- Use only suitable tools.

- Wear appropriate clothing, and put on gloves and goggles whenever required.

- The product must be secured so as to prevent it from overturning or falling down,

e.g., from the work bench.

- Clean and disinfect the product before starting inspection. Observe the instructions

for care in addition to any product-specific inspection instructions included in the

operating instructions.

- Screws and nuts with thread locks are used in very many screwed connections.

The corresponding nut or screw must be replaced by a new nut or screw with

a thread lock whenever a screwed connection with a thread lock needs to

beopened.

If screws or nuts with a thread lock should be unavailable, be sure to use a liquid

thread locking compound with medium strength (e.g., Euro LockA24.20).

- Some parts are very heavy as, e.g., batteries, frame, seat, or motors!

Be sure to use a correct ergonomic approach when lifting these heavy parts.
