MOUNTING - HITCH FITTING
SAFETY FIRST
ALWAYS work in pairs (2 skilled operatives) whenever Earth Drill unit components are
being assembled or disassembled from the parent machine. Always check the weight of
the attachment and ensure you have the correct equipment for handling it.
ALWAYS check parent machine:
•Isincorrectworkingorder
•Isparkedcorrectlyonatground
•HasitshandbrakeON.
•Usesuitablyratedliftingequipmentifrequired(seedataplateforweight).
FITTING: Ensure all components are greased on assembly:
Step 1
Lift the quick attach plate locking pins up and turn them
backwards into the slot so that they are locked in the upper
position.
If your loader is equipped with a hydraulic attachment locking
system, see additional instructions about the use of the locking
system from the relevant manuals.
Ensure that the hydraulic hoses are not in the way during
installation.
Step 2
Turn the quick attach plate hydraulically to an obliquely
forward position.
Drive the loader onto the attachment. If your loader is equipped
with a telescopic boom, you can utilise this.
Align the upper pins of the loader’s quick coupling plate so that
they are under the corresponding brackets of the attachment.
Step 3
Lift the boom slightly – pull the boom control lever backward to
raise the attachment off the ground.
Turn the boom control lever left to turn the bottom section of
the quick attach plate onto the attachment.
Lock the locking pins manually or lock the hydraulic locking.
Always check the locking of pin / pins.
DIN 1284

www.avanttecno.com 1515
Unlocked attachment may fall on the boom or
operator and cause serious injuries. Before
moving or lifting the attachment, ensure that the
locking pins are in the lower position and come
through the fasteners on both sides.
Do not use the automatic return of the locking
pins when the attachment or the boom has
been lifted at a height of over one metre. Excess
tilting increases the risk of toppling over. We
recommend that you lower the attachment onto
the ground and secure the locking manually
Step 4
Swing the frame to the vertical postion.
Working as a pair, lift the Earth Drill in to place
with the port opening facing to the left.
Align hood ears with the hole in the linkage
block.
Secure the Earth Drill with the Pin (1),Washer
(2) and Nylon Insert Nut (3)

HYDRAULIC CONNECTIONS
WARNING:
Hydraulic fluid under pressure can penetrate the skin or eyes and cause serious
personal injury, blindness or death. Fluid leaks under pressure may not be visible. Use
a piece of card or wood to find leaks. DO NOT use your bare hands. Wear safety goggles
to protect your eyes. If any fluid is injected into the skin, it MUST be surgically removed.
Seek immediate medical attention.
All Avant Tecno Oy Earth Drill Units require a
‘flow’ and ‘return’ of hydraulic oil from the parent
machine’s auxiliary hydraulic power supply to
operate. All gearboxes are reversible, but require
the host machine to be fitted with a two-way flow
auxiliary circuit.
When fitting hydraulic hoses, ensure that they
are tightened to the correct torque for the hose
fittings (Fig A).
Ensure that the drilling rotation of the Earth Drill Unit is clockwise.
It is critical that the supply of oil is within the stated flow & pressure limits for the particular
Earth Drill; Refer to the serial plate on the top of the Earth Drill hood (see page 4).
Connecting the Multiconnector System
Align the pins of the attachment connector with
corresponding holes of the loader connector. The
multiconnector will not connect if the attachment
connector is upside down. Connect and lock the
multiconnector by turning the lever towards the
loader.
The lever should move easily all the way to
its locking position. If the lever does not slide
smoothly, check the alignment and position of
the connector and clean the connectors. Also
shut down the loader and release the residual
hydraulic pressure.
To disconnect the multiconnector system, turn off
the auxiliary hydraulics of the loader, and unlock
the multiconnector. To unlock, push the knob on
the side of the connector, and turn the lever to
disconnect.

Hoses Specifications
Replacement hydraulic hoses MUST be rated equal or greater than the minimum working pressure.
Conventional Quick Couplings
(alternative couplings for some loader models)
Before connecting or disconnecting the standard quick couplings, the
residual pressure must be released as shown below. The conventional
quick couplings will not connect, if there is pressure in the hydraulic
system.
To connect and disconnect the standard couplings, move the collar at the end of the female fitting.
The hoses should be connected so that the fitting equipped with a coloured cap is connected to the
corresponding fitting of the loader Note that the protective caps on the loader and the attachment
can be fastened to each other during operation to reduce the accumulation of dirt. When
disconnecting the standard quick couplings a small amount of oil may drip from the couplings.
Wear protective gloves and have some cloth at hand to keep the equipment clean.
Make sure that all three couplings are properly connected, otherwise the hydraulic motor of the
mower may get damaged. Before disconnecting conventional quick couplings shut down the loader
and move the auxiliary hydraulics control lever of the loader to its extreme positions to release the
residual pressure of the hydraulic system.
Releasing Residual Hydraulic Pressure
To make sure that there will not be residual pressure in the hydraulic system of the attachment,
shut down the loader engine and move the auxiliary hydraulics control lever of the loader to it’s
extreme positions before disconnecting the couplings. If the fittings will not connect to the loader,
the residual pressure must be released. The residual pressure must be released before handling
the blades of the attachment and before storage of the attachment.

RUNNING-IN
To maximise the life of the unit, it must be run
in for a period .
To carry out the running in procedure, suspend
the Earth Drill in it’s vertical, working position.
For the duration of the running in procedure,
ensure that no bystanders (including animals)
can get within 6 metres/20 foot of the work
area.
Operate the motor at 30% of rated pressure for
20 minutes in each direction before application
of full operating load.
To further ensure best motor life and maintain
warranty, refer to page 27 for lubrication
instructions.

FITTING THE AUGER
SAFETY FIRST
ALWAYS work in pairs (2 skilled
operatives) whenever Earth
Drill Unit components are being
assembled or disassembled from
the parent machine.
ALWAYS check parent machine:
•Isincorrectworkingorder
•Isparkedcorrectlyonatground
•HasitshandbrakeON, its
hydraulic circuit locked out and its
engine switched OFF.
CHECK that the Auger is the correct model
and type to fit the Earth Drill Unit.
ENSURE that the Auger connections are clean
before fitting.
USE suitably rated lifting equipment if required
(see data plate for weight).
Position the Auger in the vertical work position
and support it so that it cannot fall over.
Position the Earth Drill over the Auger and
align the pin holes.
Lower the Earth Drill Unit onto the Auger
Locate the Auger Drive Pin
Secure the Auger Drive Pin with Linch Pin

www.avanttecno.com 2020
PREPARATION
CONSIDER the topography (e.g. risk of subsidence, slope angle, position to
embankments and any previous excavation).
NOTE the type of soil and its condition to enable selection of suitable teeth and pilot
ALWAYS carry out a site survey and risk assessment BEFORE starting work
AVOID underground hazards, such as water / gas / electricity / communication lines etc.
If in doubt detection equipment and professional advice should always be considered before
carrying out any work.
