1 Introduction

1.1 General information

• All maintenance and overhaul work must be carried out in accordance with these repair

instructions.

• Please observe all safety instructions.

• Information about operation or about general maintenance and care work should be taken

from the electric vehicle Operating Manual.

• You can find information about ordering spare parts in the spare parts catalogue.

• Use only genuine Invacare® spare parts. Using parts from any other source will void the

warranty!

• We reserve the right to make any alterations on the grounds of technical improvements.

• The electric vehicle may only be maintained and overhauled by qualified personnel.

• The minimum requirement for service technicians is relevant training, such as in the cycle or

orthopaedic mechanics fields, or suitably long-term job experience.

- Experience and knowledge of electrical measuring devices (Multimeter)

is also a requirement.

- Special Invacare training sessions are recommended.

• Alterations to the electric vehicle which occur as a result of incorrectly or improperly executed

maintenance or overhaul work lead to the exclusion of all liability on the part of INVACARE.

• If you have any problems or questions please contact INVACARE SERVICE.

1.2 Notes on transport

• If the electric vehicle has to be shipped back to the manufacturer for major repairs, you should

always use the original packaging for transport.

• You should also include as accurate a fault description as possible.

2 Safety and assembly instructions

These safety instructions are intended to prevent accidents during work and it is imperative that

they are observed.

2.1 Before any inspection or repair work

• Read and observe this repair manual and the associated operating manual!

• Observe the minimum requirements for carrying out the work (see chapter entitled "General

information”)!

2.2 General safety information and notes on assembly / disassembly

Danger of injury by crushing!

• Please note the heavy weight of some components. This applies especially to removal of

drive units and batteries!

• Prop up the lifted electric vehicle with appropriate supports before starting the disassembly or

assembly!

Danger of fire and burns due to electrical short-circuit!

• The electric vehicle must be switched off before removal of voltage-carrying components! To

do this, disconnect the batteries!

• When making measurements on voltage-carrying components, avoid short-circuiting the

contacts. Danger of fire and combustion!

Danger of injury and damage to the vehicle can result from incorrect or incomplete

maintenance!

• Only ever use tools which are undamaged in good condition!

• Some moving parts have Teflon bushings! These parts must never be lubricated with grease!

• Never use standard nuts instead of self-locking nuts!

• Always use correctly dimensioned washers or spacers!

• Cable binders which have been cut off during disassembly should be replaced with new ones

during reassembly!

• After completing maintenance work and before operating the electric vehicle, make sure all

fixations are correctly secured! Check all parts for correct interlocking1

• Only operate the electric vehicle with correct tyre pressure (see Technical Specifications)!

• Check electrical components for correct functioning, incorrect polarity of cables can result in

damage to the electronics!

• As a last check, always carry out a test-drive!

Notes

Mark all current settings for the electric vehicle (seat, armrests, backrest etc.), and the cable

connecting plugs associated, before any removals. This makes reassembly easier.

All plugs are fitted with mechanical safety devices which prevent release of the connecting plugs

during operation. To release the connecting plugs the safety devices must be pressed in. When

reassembling, ensure that these safety devices are correctly engaged.

WARNING: Any alteration to the drive programme can influence vehicle handling and the

tipping stability of the electric vehicle!

• Alterations to the drive programme may only be carried out by trained Invacare® dealers!

• Invacare® supplies all electric vehicles from the factory with a standard drive programme.

Invacare® can only assume a warranty for the safe vehicle handling of the electric vehicle –

in particular tipping stability - for this standard drive programme!
