Lubricating the gear wheel
►
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.
►
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 lithium 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 Li-ion battery 38 .
►
Remove both screws 6 , 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.

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 GT146 19 precision adjusting aid into the 2 holes of the adjust-
ing screw 10
Note
Knurled screws of older shearing heads that do not have
2 holes can be retrofitted with the GT147 adjusting
screw.
CAUTION
Damage to the clipping machine or
the gear wheel due to incorrect
lubrication!
►
Use only gear grease GT605.
►
Lubricate the gear wheel 1 to 2
