Introduction
This manual contains servicing instructions for the MC Concept
1122.
The Service Manual is a supplement to our Spare Parts
Catalogue and User Manual.
MC Concept 1122 is designed for safe travel for at least 10
years, up to a max. of 5,000 hours, provided it is serviced and
safety-checked every year, corresponding to 500 hours of
operation. The service must be carried out by an authorised
workshop.
IMPORTANT! For safety reasons it is of the utmost importance
that the servicing and safety check intervals are complied with,
as this minimises the risk of brake failure and short-circuits in
the wiring, which could generate heat and cause a re.
If help is required with troubleshooting, Medema Production A/S
is always happy to provide telephone assistance. If the problem
seems to be an electrical fault that prevents the MC Concept
1122 from working, please tell us the error code. This can be
found on the battery indicator on the control panel. Read more
about this in the section on Troubleshooting.
Please also have the MC Concept 1122 serial number handy

Safe servicing
To avoid injuries to both the service engineer and the
subsequent user of the MC Concept, it is important to get to
know the product before servicing it.
Be particularly aware of the following:
The MC Concept MUST be turned off at the main switch. If
electrical components are being serviced, the positive terminal on
the battery MUST also be disconnected.
If the voltage needs to be measured in the course of
troubleshooting, take great care not to short-circuit anything.
Take great care not to short-circuit the battery terminals.
Be careful not to lift heavy parts such as the seat, battery and
motor gear incorrectly or drop them.
Make sure to raise one rear wheel off the ground so that the MC
Concept cannot drive off accidentally.
Use professionally maintained tools.
Where lock nuts are used, NEW ones MUST be tted when the
MC Concept is reassembled.
Take care to t new cable strips in the same way as the old ones.
Make sure that no cables can be trapped by moving parts or stick
out in such a way as to catch on things.
End every service by making sure that the product is roadworthy:
- Check that all the connectors are plugged in correctly.
- Check that all the mechanical parts are properly secured.
