2 Safety and fitting instructions
These safety instructions are intended to prevent accidents at 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 Personal safety equipment
Safety shoes
The mobility device, and some of its components, are very heavy. These parts can result
in injuries to the feet if they are allowed to drop.
•Wear standardised safety shoes during all work.
Eye protection
It is possible that battery acid can be discharged when working on defective batteries or
when handling batteries improperly.
•Always wear eye protection when working on any defective or possibly defective batteries.
Safety gloves
It is possible that battery acid can be discharged when working on defective batteries or
when handling batteries improperly.
•Always wear acid-proof safety gloves when working on any defective or possibly defective
batteries.
2.3 General safety information and information about fitting / removal
WARNING: Danger of crushing!
Various components such as the drive unit, batteries, seat etc are very heavy. This results
in injury hazards to your hands!
•Please note the high weight of some components! This applies especially to the removal of
drive units, batteries and the seat.
WARNING!
Injury hazard if the vehicle starts moving unintentionally during repair work!
•Switch the power supply off (ON/OFF key)!
•Engage the drive!
•Before raising the vehicle, secure the wheels by blocking them with wedges!
ATTENTION!
Fire and burn hazard due to electrical short-circuit!
•The mobility device must be completely switched off before removal of voltage-carrying
components! To do this, remove the batteries.
•Avoid short-circuiting the contacts when carrying out measurements on voltage-carrying
components!

SERVICE MANUAL Invacare®- Colibri
12
CAUTION!
Danger of burns from hot surfaces on the motor!
•Allow the motors to cool down before commencing work on them.
ATTENTION!
Injury hazard and danger of damage to vehicle due to improper or incomplete
maintenance work!
•Use only undamaged tools in good condition.
•Some moving parts are mounted in sockets with PTFE coating (Teflon™). Never grease these
sockets!
•Never use "normal" nuts instead of self-locking nuts.
•Always use correctly-dimensioned washers and spacers
•When reassembling, always replace any cable ties which were cut during dismantling.
•After completing your work / before renewed start-up of the mobility device, check all
connections for tight fitting.
•After completing your work / before renewed start-up of the mobility device, check all parts for

Blink
code Fault Consequence for the Scooter Comments
1 Battery must be
charged Continues to drive •The batteries are discharged. Charge the
battery as soon as possible.
2 Battery voltage too
low Stops driving •The batteries are depleted. Charge
batteries.
•If you switch the Scooter off for a few
minutes, the battery can often recuperate
to such a stage that a short journey is still
possible.
3 Battery voltage too
high Stops driving •The battery voltage is too high. If the
battery charger is connected, disconnect
it from the Scooter.
•The electronic system charges the
batteries when running downhill and
when braking. This fault is caused when
the battery voltage becomes too high
during this process. Switch the Scooter
off and on again.
4 Power time
exceeded Stops driving •The maximum current was exceeded
over too long a period, probably because
the motor was overloaded or has been
working against an immovable
resistance. Switch the scooter off, wait a
few minutes and then switch on again.
•The electronic system has determined a
motor short-circuit. Check the wiring
harness for short-circuit and check the
motor.
•Contact your Invacare® dealer.
5 Brake failure Stops driving •Ensure that the disconnection lever is
pressed in.
•There is a defect in the braking coil or in
the cabling. Check the magnetic brake
and cabling for open or short-circuited
circuitry. Contact your Invacare® dealer.
6 No neutral position
when switching
Scooter on.
Stops driving •Drive lever is not in neutral when the
keyswitch was turned. Put the drive lever
in neutral, turn the power off and then
turn on again.
