Your Marcrist diamond-drilling machine is manufactured to the highest possible
standards. Continuous satisfactory operation depends upon the proper servicing and
maintenance of the drilling machine.
For your safety the machine must be serviced every time you have collected 10
vouchers (meaning you will have very extensively used the machine) or, at 18 month
intervals. The guarantee may, at the sole discretion of Marcrist, become null and void, if
the machine is not serviced every 10 cores or within 18 months (whichever is the
soonest).
If replacement of the supply cable or plug is necessary, take the DDM2 - 230
to your nearest Marcrist Distributor to avoid a safety hazard.
Keep the ventilation slots clear of dust and foreign objects. Regularly clean the machine
with a damp cloth. Do not use chemicals to clean the machine.
