OPERATION
SELECTING THE GRINDING STONE
In general, coarse grinding stones are used to remove
material and fine grinding stones to finish the workpiece.
If the surface is uneven, start with the coarse grinding
stone until the surface is smooth. Then use the fine grin-
ding stone to remove any scratches caused by the coarse
grinding stone to finish the workpiece.
GRINDING
The grinding machine comes with one grinding disc for
dry grinding and one for wet grinding. In principle, the
dry-grinding disc is suited for corase grinding and the
wet-grinding disc for fine grinding where it suffices to
press the workpiece lightly against the grinding stone.
This grinding machine has been especially designed for
treating and grinding tools with cutting edges such as kni-
ves, scissors, chisels, etc. For best results, fill the water
container with tap water.
Do not “fill up” the stone by holding wood, lead or any
other soft metal against the grinding stone. Never press
the workpiece too hard against the stone, to avoid
making grooves. Cool down the workpiece with water.
Wood chisels and such must never “blue” when being
ground. Make sure the workpiece cannot slip from your
fingers during grinding and get caught between the tool
rest and the stone. This may cause the stone to crack,
the motor to stall and the workpiece to rebound, cau-
sing injuries.
OPERATION

MAINTENANCE
Make sure that the machine is not live when car-

The Ferm machines have been designed to operate over
a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon pro-
per machine care and regular cleaning.
Cleaning
Regularly clean the machine housing with a soft cloth,
preferably after each use. Keep the ventilation slots free
from dust and dirt.
If the dirt does not come off use a soft cloth moistened
with soapy water. Never use solvents such as petrol,
alcohol, ammonia water, etc. These solvents may
damage the plastic parts.
Lubrication
The machine requires no additional lubrication.
