1. Introduction
Dear Customer,
We thank you for having chosen a
L
LI IP PC CO O S St tu um mp p C Cu ut tt te er r
. We hope
that you will be happy with your choice.
In order that your

6. Accident prevention
Most accidents that occur during work, maintenance or transport of a
machine are due to non-observance of the most elementary rules of
accident prevention.
It is, therefore, necessary that all licensed users (relatives,
employees, colleagues) read and observe the rules given below and
written on the adhesive labels of the machine itself:
•Only work with eye and ear protection! (we recommend a
complete helmet combination)
•Turn off the engine of the engine-driven machine before carrying
out any adjustments, maintenance or cleaning on the machine!
•Prior to any work on the machine, it should be placed on level
ground! When working on the lifted unit, always ensure
mechanical protection by means of adequate supporting
elements!
•In order to achieve the highest possible performance of the
L
LI IP PC CO O S St tu um mp p C Cu ut tt te er r
, it must always be in perfect condition.
Maintenance and repairs must be carried out by trained persons
only! Spare parts must at least comply with the technical
requirements specified by the manufacturer! This is only
guaranteed for
L
LI IP PC CO O o or ri ig gi in na al l s sp pa ar re e p pa ar rt ts s
!
•Before each use, screws and nuts must be checked to ensure
they are firmly tightened, especially those of the tools and the
drive flange!!
•Before starting up, please make sure that no people or animals
are in the vicinity.
•Take special care when working alongside roads or pathways.

•During service or repair work, make sure that no one can start up
the machine accidentally!
•Do not, for any reason, climb onto the machine during operation.
•Do not act with any objects on the machine during operation!
•Never work without machine protection hood and plastic apron!

7. Design features
The
L LI IP PC CO O S St tu um mp p C Cu ut tt te er r
, when connected to any type of engine-
driven machine from 7 kW, is capable of removing tree stumps.
The main characteristics of the
L
LI IP PC CO O S St tu um mp p C Cu ut tt te er r
are its universal
attachment to different engine-driven machines and its reduced
machine width, offering the possibility of achieving optimum work
results on narrow access roads and in very limited space.
As shown on the figure, the cutting disc of the
L
LI IP PC CO O S St tu um mp p C Cu ut tt te er r
is equipped with exchangeable cutting blades (with soldered-on
hard-metal plates)
The decisive feature of the
L
LI IP PC CO O S St tu um mp p C Cu ut tt te er r
is the pivoting
device. (Fig. 2)
The attached engine-driven machine is lifted, leading to an oscillating
balance between the motorised device and the stump cutter. This
balance allows the machine to be lifted easily over the tree stump.
Thus, no tiresome pivoting over the motorised device axis is
necessary.

9. Preparation
•Important! Adjust the
balance between motor
device and stump cutter
before the start-up! In this
adjustment, the bearing
arms of the support are
extended or shortened
depending on the
motorized device. To do
so, the fixing screws (A)
have to be removed and
the internal tubes (B) to be
pushed to the desired
position. Then, the bearing
arms have to be fixed with
the screws.
•Aim at maximum rotating disc diameter, since this leads to a
higher stability! Larger rotating discs can be ordered from the
manufacturer.
•Check the oil level in the angular gear! (see chapter:
“10. Maintenance”)
•Check whether all safety devices are in place and all screws are
tightened, especially the screws of the cutting blade and the
drive flange.
•Attach the handle! (Tighten the screw and counter it with the lock
nut.)

10. Connection to the engine-driven machine
Before attaching the machine flange (Fig. 3, Ref. A) corresponding to
the type of engine-driven machine you have, it is recommended to
spread grease on the outer diameter of the machine hub (Fig. 3, Ref.
B). Then fix the flange with its two safety screws (Fig. 3, Ref. C) and
the lock nuts.
After having greased the connecting shaft (Fig. 3, Ref. D), insert it on
the machine shaft. When these steps are complete, move the
engine-driven machine close to the unit.
Ensure the toothed wheel work of the connecting shaft engages
correctly with the power takeoff shaft of the engine-driven machine
and the flange has a centred contact with the engine-driven machine.
Then connect the flange of the unit to the engine-driven machine.
Before beginning work: Lubricate the drive flange on the lubricating
nipple (Fig. 3, Ref. E)

11. Working with the LIPCO Stump cutter
Move the Stump Cutter to the tree stump to be cut. Position the unit
such that the cutter disc is located centrally above the tree stump.
Then wind the support wheel to the top position. Lift the machine via
the pivoting device until reaching a distance above the ground of
approx. 10 cm. Do not switch on the power takeoff shaft under load;
therefore, lift the stump cutter so that the cutter disk does not contact
the tree stump when the machine is switched on.
When full speed is reached, lower the stump cutter carefully until the
disc cuts into the wood. Now, pivot the stump cutter to the right and
to the left over the tree stump and repeat the cutting process until the
desired working depth is reached.
Depending on the trunk diameter, the machine has to be shifted
forward or backward.
For safe and optimum working, it is necessary that the rotating disc
contacts the stump evenly, in some cases a support has to be
provided.

When working with a second person, the additional handle is
clamped firmly on the machine. Now, the second person can assist
the machine operator "from the front".
•Attention!
Turn off the engine of the engine-driven machine before
making any adjustments (e.g. winding the pivoting device
upward). In case of vibrations, immediately stop working
and inspect the cutting blade. Due to the high speed, an
imbalance might be caused by missing or seriously
damaged cutting blades.
•Only work with the personal protection equipment! (Eye and ear
protection)
•Attention!
When working in hillside position, the tree may only be cut
uphill or downhill for safety reasons. Never sideways!

12. Maintenance
Steps to be carried out in order to maintain the machine in good
working condition:
•Check the oil level in the
angular gear. (Fig. 4) In
horizontal position the
gear drive should be
filled with gear oil to the
lower edge of the filler
neck. The first oil
change should be
carried out after 50 to
60 operating hours.
•Use SAE 90 gear oil in
an amount of 0.85 L.
•Drive flange: It should
be lubricated at least
once a month via the
lubricating nipples
provided for this
purpose. (Fig. 5)
•Then turn the drive
flange to allow the
grease to become
evenly distributed –
while doing so, check
for smooth running.
•Remove drive flange once a year, clean and regrease it.
•Check the plastic apron and replace it, if necessary!

•Check whether all screws, especially those of the cutting blades,
are firmly tightened. Replace damaged screws immediately.
(See chapter "11. Replacement of the cutting blades").
Note: Only use original screws.
•Lubricate movable parts, e.g. pivoting device at the bearing
points.
•The lubricating nipple on the supporting wheel must be
lubricated once a month.

13. Replacement if the cutting blaeds
When replacing the cutting blades, make sure that the machine is
secured against unintentional tilting! When working with the unit
lifted, always ensure mechanical protection by means of adequate
supporting elements!
When a cutting blade becomes broken, immediately stop work and
replace the damaged parts.
