1.1 Preface

These service instructions describe all regular maintenance tasks as well as repair and replace-

ment tasks for the ParaGolfer sports wheelchair from Ottobock. They include all information

required by dealers in order to correct functional and mechanical defects in components of the

ParaGolfer.

The information in these service instructions is essential in order to work on the ParaGolfer cor-

rectly and safely. This is why this document, in particular the section “Safety Instructions”, must

be read carefully by all persons working on the ParaGolfer. This ensures the functionality of the

ParaGolfer is fully utilised.

1.2 Intended Use

The ParaGolfer is designed solely for persons who are unable to work or have a walking impedi-

ment for doing indoor or outdoor sports that require an upright body position. The ParaGolfer

was specially designed for users who are able to independently move in a power wheelchair.

Any other use is considered improper use. The manufacturer is not liable for any personal injury

or damage to property resulting from improper use; in such cases, the user has sole liability.

The ParaGolfer may only be used by properly trained persons. Training is one of the prerequisites

in order to protect against personal risks and in order to operate the ParaGolfer safely and

properly.

2.2 Standards and Directives

All safety information contained in these service instructions refers to the currently valid national

laws and regulations of the European Union. In other countries, compliance with the applicable

laws and national regulations is required.

In addition to the safety instructions contained in these service instructions, the BGV (Employer’s

Liability Insurance Association regulations), UVV (accident prevention regulations) and environ-

mental protection regulations must be observed and complied with. All information contained in

these service instructions must be complied with at all times without restrictions.

The electrically operated ParaGolfer sports wheelchair has been constructed in accordance

with state-of-the-art technology and is safe to operate. The safety of the ParaGolfer has been

conrmed by CE certication and the declaration of conformity.

tools that are suitable for the conditions at the place of work and for which safety and the protection

of health are assured with proper use.

Verify proper functionality before use. In the use of tools and supplies, also consider the ergonomic

relationships between the place of work, tools and supplies, workplace organisation, workow and

tasks; this is particularly important in regards to posture during the use of tools and supplies.

Some components of the ParaGolfer, e.g. the batteries, frame, seat and motors, are very heavy.

Hoisting devices of sufcient capacity must be used where applicable.

has been tested and approved for the respective batteries by Ottobock (observe information on the

charger). Failure to do so can result in a battery explosion and possible impairment of health due to

contact with battery acid.

Smoking and open ame are prohibited while working on the battery. Sparks must be avoided.

Explosive gases can develop while the batteries are charging. Observe the safety information provided

by the battery manufacturer. Wear protective goggles. Ensure sufcient ventilation when charging the

batteries in an enclosed room.

Drive batteries can supply very large amounts of energy and may arc if they are short-circuited. There-

fore, always disconnect the batteries when working on the motor control or wiring.



The ParaGolfer has been tested according to EMC regulations. The following particularities must be

observed when using the wheelchair:

•

The driving characteristics of the ParaGolfer can be affected by electromagnetic elds (mobile phones

or other radiating devices). Therefore all mobile devices must be turned off when driving.

• The ParaGolfer can generate electromagnetic elds that can cause interference with other devices.

Therefore, turn off the control unit whenever you do not need it.



During extended periods of disuse or shipment of the ParaGolfer, remove the fuse from the battery case

in order to prevent deep discharge of the batteries due to standby consumption.

3.2 Storage



If the power wheelchair is not moved for several days, permanent colour changes may occur where

the wheelchair comes into contact with the surface it is standing on. Ottobock therefore recommends

parking the wheelchair on a suitable surface during extended periods of disuse.

Required Tools and Aids

ParaGolfer12 | Ottobock

The power wheelchair must be stored in an enclosed area. Remove the main fuse; otherwise,

there is a risk of deep discharge.

The storage location must be dry and have sufcient air circulation. There must not be any build-

up of humidity. The ParaGolfer must not be subjected to any damaging exterior inuences, e.g.

rain, snow, or strong solar radiation during storage.

Ottobock recommends storing the ParaGolfer with slightly elevated tyre pressure and using

assembly stands or wooden blocks in order to raise the tyres (completely) off the ground in order

to protect them from frost. Regularly rotating the wheels helps to prevent at spots.

6.1 Inspecting the General Condition

❒Check all safety-related components for corrosion, repair if required and reapply corrosion

protection.

❒Check weld seams.

❒Check tightness of screw connections; replace thread-locking compound if required;

observe any dened torque specications; replace defective screws (e. g. in case of

corrosion).

❒Check cables for ruptures, signs of wear and proper attachment; replace defective cables.

❒Check cable connections and plug connections.

6.2 Battery Disconnect Switch

The ParaGolfer is equipped with a battery disconnect switch. This battery disconnect switch is

located underneath the seat next to the fuse box.

If you pull off the battery disconnect switch, the entire control of the ParaGolfer is blocked.

To do so, turn the battery disconnect switch by 90° and then pull it off.
