B.2 Technical data
Remove the mains plug before undertaking maintenance
or cleaning.
Never remove safety equipment or disable it by modifying
the machine.
Any alterations or repairs to the electrical system must
be carried out by a qualified electrician.
Only use original spare parts from GS-Schleiftechnik.
B.3 Installing and connecting the machine
6
Mount the knife grinding machine on a solid, flat surface. The ventilation ducts on the
machine's underside must not be covered. Connect the machine to a 230 V AC supply
protected by a 16 A fuse, and fill the water basin with about 4 cm of water.
B.4 Adjusting the grinding clearance guides
After releasing the clamping levers, slide the grinding
clearance guides towards the grinding wheel to give a gap of
approx. 1/2 mm. Then retighten the clamping levers. If the
clamping lever is lowered it can be turned without slackening
the screw tension.
B.5 Replacing the grinding stones
Remove the grinding clearance guides. Hold the grinding stone in one hand, and loosen the
tensioner bolt with a 17 mm spanner in the turning direction of the grinding stone. The bolt on
the right side has a left-hand thread. Remove the bolt with the tensioner flange, and the
grinding disc can be pulled out from the side. Reassembly is the reverse of disassembly.
Before fully tightening the tensioner bolt, line up the grinding disc by gently tapping with a nylon
hammer or a block of wood.
C Operation
C.1 Grinding
Before grinding, remove any grease or other residue
from the knife. Place the knife in the grinding clearance
guide and slide it backwards and forwards along the
cutting edge with a small amount of pressure. Repeat
several times, on the right and the left of the grinding
disc. Make sure that the knife is correctly placed in the
grinding clearance guides so that it is sharpened
uniformly. Continue until both sides of the cutting edge
have a constant burr. This is likely to take some time
on an old, heavily used knife. The degree of hardness
of the knife's blade will also affect its sharpening time.
C.2 Polishing and honing
Repeat the procedure as for grinding, but using the polishing and honing stone. Within a short
time the cutting edge is polished. Then hone the blade with minimum pressure.
Once a knife has been properly ground and polished, the procedure does not have to be
repeated every time the blade needs sharpening. The knife only needs to be reground when
polishing and honing fails to sharpen the blade.

D Cleaning and maintenance
D.1 Cleaning
Over time, dust from the grinding process builds up on the polishing and honing disc. To
remove this, hold the supplied dressing stone hard against the grinding surface. If grease has
got onto the grinding stones despite cleaning the knives, just add solvent to the water.
The water basin should also be cleaned from time to time to remove grinding dust.
Warning!
D.2 Maintenance
The knife grinding machine is completely maintenance-free. In the unlikely event of a fault
occurring on your machine, please contact our customer service department.
Remove the mains plug before undertaking maintenance or
cleaning.
Never remove safety equipment or disable it by modifying the
machine.
Any alterations or repairs to the electrical system must be carried
out by a qualified electrician.
Only use original spare parts from GS-Schleiftechnik.
D.3 Authorized cleaning agents
Cleaning agents and procedures commonly used in the food industry can be used for cleaning
and disinfecting the machinery. Only use legally permitted cleaning agents.
