Handling the cutter head

Lubricating the shearing head
Damage to the clipping machine or the
cutter head due to incorrect lubrica-
CAUTION
tion!
Only oil the cutter head when the
►
machine is running.
Never immerse the cutter head in
►
liquid of any kind!
Only use GT604 light lubricating oil.
►
►
Generously oil the cutter head at the lubrication point a before shear-
ing each animal, see Fig. A.
►
Oil spring leaves 7 2 to 3 times daily with 3 to 4 drops of oil, see Fig. C.
Lubricating the gear wheel
Damage to the clipping machine or the
gear wheel due to incorrect lubrica-
CAUTION
tion!
Use only gear grease GT605.
►
Lubricate the gear wheel 1 to 2
►
times during the shearing season.
►
Unlock and remove the lithium ion battery 21.
►
Remove both screws 14, see figure B.
►
Then turn the cutter head very slightly (about 15°) counterclockwise
and remove it from the motor shell.
►
Apply approximately 1 cm of grease on the two opposite points of the
gear wheel 12, see Fig. C.
►
Carefully place the cutter head on the motor. When re-attaching the
cutter head, ensure that it is turned 15° counterclockwise in such a
way that its lower flange engages with the groove of the motor hous-
ing.
Changing the cutter plate
►
Unlock and remove the Li-Ion battery 21.
►
Loosen the knurled nut 11 and adjusting screw 10 by approximately
2 turns, see Fig. A.
►
Loosen both clamp screws 4, pull off the lower cutter plate 2 forwards
and remove the upper cutter plate 3, see Fig. A and E.
►
Before inserting the upper cutter plate 3, ensure that the oscillating
block 13 is in the intended recess of the oscillator 5, see Fig. E.
►
Insert the upper cutter plate 3. When doing so, ensure that both tips b
of the oscillator 5 engage precisely in the holes c of the upper cutter
plate 3, see Fig. D.
►
Push the lower cutter plate 2 below the heads of the clamping screws 4
all the way on to the cutter head shell and screw both clamping screws
4 tight.
►
Tighten the adjusting screw 10 until both cutter plates are pressing
slightly against one another, see Fig. A.

Cleaning the cutter head
►
The cutter head must be cleaned at least after each day of clipping time
or if it gets dirty.
►
Unlock and remove the lithium ion battery 21.
►
Remove both screws 14, see Fig. B.
►
Then turn the cutter head very slightly (about 15°) counterclockwise
and remove it from the motor shell.
►
Remove the cutter plates, see Changing the cutter plate.
►
Thoroughly clean the interior part and individual parts of the cutter
head using a brush.
►
Insert the cutter plate and tighten, see Changing the cutter plate.
►
Lubricate the gear wheel, see Lubricating the gear wheel.
►
Carefully place the cutter head on the motor. When re-attaching the
cutter head, ensure that it is turned 15° counterclockwise in such a
way that its lower flange engages with the groove of the motor hous-
ing.
►
Lubricate the cutter head, see Lubricating the shearing head.
Adjust plate pressure with GT146 precision adjusting aid (optionally
available)
Note
The manufacturer recommends the GT146 precision
adjusting aid for optimal adjustment of the plate pres-
sure.
►
Insert precision adjustment aid GT146 19 into the 2 holes of the
adjusting screw 10 and turn clockwise until there is an audible click.
Note
Knurled screws of older shearing heads that do not have
2 holes can be retrofitted with the GT147 adjusting
screw.
Adjusting the plate pressure
Note
The plate pressure must be set with the machine running
and without auxiliary tools.
Note
If the plate pressure is too high, this results in the build-
up of heat and greater wear to the cutter plates.
►
Loosen the knurled nut 11 and the adjusting screw 10 carefully until
the upper cutter plate 3 is no longer pressing against the lower cutter
plate 2 (the sound of the motor becomes noticeably higher-pitched);
see figure A.
►
Screw in the adjusting screw 10 until you feel slight resistance. From
this point, keep turning approximately one full turn and then tighten
the knurled nut 11.
