1.1 Intended purpose
The HV 150 hand knife grinding attachment is used to grind hand knives. This attachment is
meant to be installed onto KNECHT grinding machines of the USK 160 S series.
1.2 Mounting the HV 150 hand knife grinding attachment
1.2.1 Mounting the CBN grinding wheels
Mount two CBN grinding wheels in order to grind
hand knives using the HV 150.
To do so, loosen the star handles (1-1/1) on the
left-hand side of the machine and remove the
protection hood. Then remove the finned grinding
wheel.
Use a spanner wrench (SW22) to loosen the nut
(1-2/1) of the grinding spindle.
Loosen = turn left (in the direction of rotation)
Tighten = turn right (against the direction of
rotation)
Pull the finned grinding wheel off the grinding
spindle.
NOTICE If the grinding spindle turns too, counter it
with a spanner wrench (SW10) on the end of
the shaft.

1. Operation
Push the intermediate flange (1-3/1) to the stop
on the grinding spindle.
Push the first CBN grinding wheel (1-4/1) to the
intermediate flange (1-4/2).
NOTICE The recess on the grinding wheel (1-4/1) must
be pointing in the direction of the machine.
Push another intermediate flange (1-5/1) to
the first grinding wheel (1-5/2) on the grinding
spindle.

Push the second CBN grinding wheel (1-6/1) to
the intermediate flange (1-6/2) on the grinding
spindle.
NOTICE The recess on the grinding wheel (1-6/1) must
be pointing outwards.
Push on the clamping flange (1-7/1) and turn the
nut (1-7/2) onto the thread by hand.
Then reattach the nuts (1-7/2) with both spanner
wrenches (SW10 and SW22).
If not yet in place, mount the stripper (1-8/1) using
the Allen key SW4 and align it with the grinding
wheels.

There is a risk that hands, hair, and clothing may be pulled in while the
grinding machine is switched on.
Serious injury may result.
CAUTION
1.3 Grinding hand knives
1.3.1 Switching on the grinding machine
Turn the main switch (1-12/1) of the USK 160 S to
the “I” position.
1.3.2 Coolant regulation
The water supply must be turned on when using
the CBN grinding wheels. If it is not activated,
push the rubber on the water nozzle (1-13/1) be-
hind the hole (1-13/2) on the water nozzle.
The quantity of coolant is regulated by the water
nozzle (7-13/1).
Turning clockwise = more water
Turning counterclockwise = less water

1.3.3 Grinding hand knives
To grind the hand knife, place the knife shaft in
the slit (1-14/1) from above and slowly pull to-
wards to the tip.
Repeat this process alternating between the right
and left sides until the desired knife sharpness is
achieved.
NOTE Always begin the grinding process on the
knife shaft.
Then deburr and polish the hand knife on the
finned brush (1-16/1) as described in the operat-
ing instructions for the USK 160 S.
Switch off the grinding machine after the grinding
process is finished.
To do so, switch the “I/ 0” main switch (1-12/1) to
the “0” position.

For all work on the HV 150 hand knife grinding attachment, the locally
applicable safety and accident prevention regulations as well as instruc-
tions in the "Safety" and "Important notes" section of the USK 160 S
universal wet-grinding machine operating instructions must be observed.
Use only original replacement and wear parts. When using external
parts, it cannot be guaranteed that they are constructed and manufac-
tured to be suitable and safe.
CAUTION
2.1 Cleaning
Clean the hand knife grinding attachment after each sharpening in order to prevent the grinding
sludge from drying and making it harder to remove.
After cleaning, lightly grease the hand knife grinding attachment with non-corrosive oil (also refer
to the lubrication schedule, Chapter 2.2).
