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.

• 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!
