5. SERVICE & VEDLIGEHOLDELSE
Sørg for at maskinen ikke står under strøm, når der udføres
vedligeholdelsesarbejder på mekanikken.
Maskinerne fra Ferm er udviklet til at fungere længe uden problemer med et minimum af
vedligeholdelse. Ved at rengøre maskinen regelmæssigt og behandle den korrekt, bidrager De
til en længere levetid for maskinen.
Fejl
For det tilfælde, at maskinen ikke fungerer korrekt, er herunder angivet en række mulige
årsager med tilhørende løsningsforslag:
Reparationer må udelukkende udføres af en autoriseret installatør eller et
autoriseret serviceværksted.
Rengøring
Rengør regelmæssigt maskinkappen med en blød klud, helst efter hvert brug. Sørg for at
ventilationshullerne er fri for støv og snavs. Brug en blød klud, der er vædet i sæbevand til at
fjerne hårdnakket snavs. Brug ingen opløsningsmidler, så som benzin, alkohol, ammoniak, osv.
Den slags stoffer beskadiger kunststofdelene.
Smøring
Maskinen behøver ingen ekstra smøring.
Fejl
Skulle en fejl opstå, f.eks. pga. slidtage af en enhed, kontakt venligst serviceadressen på
garantibeviset. På bagsiden af denne manual finder du en tegning med alle dele, der kan
bestilles.
Miljø
For at undgå transportbeskadigelse leveres maskinen i en solid emballage. Emballagen er så
vidt muligt lavet af genbrugsmateriale. Genbrug derfor emballagen.

Only ever replace the grinding wheel when the motor is at a standstill and the power
is completely disconnected.
• Remove the guards, using the above tools. When replacing the stones, remember the
right-hand spindle is fitted with right-hand thread, the left-hand spindle with left-hand
thread.
• Loosen the nut by means of the spanner. Remove the stone.
• Clean the flanges. Replace one flange, with the concave side facing the grinding stone.
Slide the new grinding stone on to the spindle. Replace the second flange on the spindle,
with the concave side facing the grinding stone. Tighten the nut securely, but not too tightly!
Replace the guards and adjust the tool rest. Let the motor run for a few seconds before you
start to grind.
4. OPERATION
Selecting the grinding wheel
Coarse grinding wheels will in general remove the most material, and fine grinding wheels are
used for finishing. If the surface is uneven, begin by using a coarse grinding wheel, and grind the
workpiece until it is smooth. Next use a fine grinding wheel to remove the grooves and
scratching left by the coarse wheel, and finish off 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
knives, scissors, chisels, etc. For best results, fill the water container with tap water.
To prevent the grinding surface from blocking up, avoid holding wood, lead or any other soft
material or metal against the grinding wheel. To avoid creating grooves, do not press the
workpiece too firmly on the grinding wheel. Use water to regularly cool the workpiece being
ground. Wood chisels and the like should never be sharpened ‘blue’.
Take care not to lose your grip on the object being ground, as it may suddenly become jammed
between the tool rest and the grinding wheel. This can cause the stone to shatter, the motor to
seize, or the workpiece to fly off, all of which can cause injury and damage.
Whenever the machine has been in use for 30 minutes, it should be switched off. Allow the
machine to cool down to room temperature.
Operation
• Check that the switch is in the “OFF/0” position before connecting the machine to the power
supply.
• Press the power switch into the “ ON/1” position to start your bench grinder.
• Always keep the power cord out of the way of the tool’s moving parts.
