MAINTENANCE

Our products are made with the finest materi-
als throughout, but even the best needs atten-
tion sometimes. To ensure a long and trouble-
free working life for your machine, we recom-
mend the following maintenance procedures.
1. Main shaft lubrication.
The main shaft bearings
are made with specially
designed oiled metal, but
should be lubricated once
every six months with
spindle oil or machine oil to ensure smooth
running.
