INTRODUCTION TO AUGERS
1.1 WHAT ARE PILING AUGERS OR PRE-AUGERS?
A Piling Auger is a type of drill that incorporates a helical screw blade, sometimes called
a ‘flight’ which in construction is used to drill or loosen earth in preparation for driving
sheet piles.
1.2 WHAT CAN MGF PILING AUGERS BE USED FOR?
Pre-augering is mainly used in difficult stiff ground conditions where it is necessary to use
the pre-drive sheet installation method to turn cohesive soil into less dense material. This
reduced density allows installation or removal of piling sheets via an Excavator Mounted
Vibrator (EMV) Hammer in conditions which without the auger would not have been possible.
1.3 WHAT ARE THE BENEFITS OF MGF PRE-AUGERS?
A Piling Auger is fitted to an excavator in the same way as an EMV and using the pre-
augering method means a vibratory hammer can be used in place of an impact hammer.
Using a piling auger as a method of preparing the soil is beneficial for several reasons:
• Alternative option if EMV sheet driving refuses due to stiff ground conditions.
• Quieter than using impact hammer.
• Reduces damage to piling sheet drive edges and EMV damage due to refusal.
• Reduced outlay vs – hiring larger impact vibro hammers and cranes. Highly specialised
install teams required for more complex methods.
• To suit excavator sizes 13t – 45t.
• Quickly interchangeable with MGF EMV units, via quick release hydraulic connections –
same flows and pressure so no setup change. Quick tool change on excavator maximises
productivity onsite.
• Quick hitch mounted – Ø65, 80, 90 & 100 diameter pin options to suit a broad range of
quick hitch types and models.
• MGF designed cradle – allows superior control of drill movement, from horizontal to
vertical orientation, connecting, and whilst tracking the excavator on site. The cradle
also functions as a carry frame and carries its own spares / tools self-contained upon it.
It features lift points compatible with MGF standard duty 4-leg chains, as well as forklift
points.
• 3.2m length custom built drills – configured with ‘Rock’ specification teeth, hard wear
pads, shallow pitch flights for the full length of drill. Heavy-duty tube construction. Fully
flighted Ø400mm diameter – or Ø600mm diameter drills available.
• Available with a telescopic extension, to add additional 0.75m or 1.5m length with ease
and quick turnaround time. Because the telescopic extension is inside the drill tube
at start of operation, full depth drilling beyond boom reach can be achieved without
disconnecting drills. Simply stop augering, remove pin, extend, or retract, re-lock,
continue augering with minimal time disruption and greater safety.

AUGER OPERATION
4.1 AS DELIVERED
The Auger motor will be delivered to site fitted on its cradle, which also acts as a
transport stillage.
The cradle will be fitted and supplied with the hirer’s choice of quick hitch head size.
The hirer’s choice of drill size will be delivered (with or without telescopic strut extension),
not fitted to the motor. If telescopic strut is specified this will be supplied in the fully
closed position.
The Auger motor will be locked to the cradle, using one of the ‘Ø30 drill locking pin and
linch pin’ – placed in the locking position hole on the cradle and secured with linch pin.
4.2 LOCKING THE MOTOR TO THE CRADLE
(FOR CROWDING, HANDLING OR TRANSPORT)
The locking pin – when fitted through the highlighted hole, passes through a lug on the
motor body. This prevents the motor from being able to articulate from its pivot on the
cradle.
THE LOCKING PIN MUST BE FITTED ANYTIME THE AUGER
IS BEING HANDLED / TRANSPORTED WHEN NOT ON THE
EXCAVATOR.
THE LOCKING PIN MUST BE FITTED BEFORE CROWDING
THE AUGER DURING LOCKING OR UNLOCKING OF THE
QUICK HITCH ON THE EXCAVATOR. SERIOUS INJURY OR
DAMAGE COULD OCCUR IF THIS STEP IS NOT UNDERTAKEN.
Note: Only the highlighted ‘locking hole’ serves this function. The other holes are for holding
spare pins only and do not provide a lock function.

Inspect locks
Connect the quick release hydraulic fittings to the relevant quick release fitted
on the excavator boom. The drain line is the smaller hose. The inlet hose will be
marked by the MGF fitter by putting red insulation tape around both hose and
quick release fitting. The outlet hose will have no colour marking.
(Note: This is the same set up for as used for MGF EMV hammer hire – so tools are
quickly interchangeable).
Note: A Pressure Reducing Valve maybe fitted to the inlet side of the boom quick release
fitting, if machine setup / flows dictate this is required.
If pressure is locked in the hydraulic lines preventing quick release fitting insertion or
removal, see sub section 5 in this guide.
Check operation of drill in both directions by using the pecker control lever.
Remove motor / cradle locking pin – stowing the pin in the cradle stowage point (secure

AUGER
Lift the drill from the floor – position can be controlled using the cradle arm.
4.6 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.
22USER GUIDE SECTION 4
AUGER
4.7 DRILLING PROCEDURE
WORKING PROCEDURE
Before commencing work, ensure that:
The correct hoses are fitted and tightened correctly.
The unit has been properly run in.
There are no bystanders within the nominated radius as defined in
the risk assessment completed prior to commencing any works.
Set Auger in a vertical drilling position
(Fig A). Ensure the direction of rotation is
clockwise. Only start drilling after a site
survey on a pre-marked safe location.
Gradually lower the parent machine arm(s)
to apply down force to the Auger. The
harder the ground the more down force
required.
Maintain drilling speed. Do not continually
stall the earth drill unit with excessive down
force, as this will overheat the hydraulic oil
and could damage the machine.
Keep the Auger vertical.
For skid steer machines (Fig B); adjust
the angle of the arms, mounting frame
and the position of the parent machine as
necessary.
For excavators (Fig C); adjust the angle of
the dipper and boom.
Maximise efficiency and avoid damaging
the Auger assembly by keeping the Auger
vertical.
Regularly raise the Auger out of the ground
to clear material from the Auger. This will
help maintain drilling effectiveness and
ensure your machine does not become
unstable.
NEVER drill beyond the length of the Auger.
NEVER leave the Auger assembly suspended.
ALWAYS park with the Auger on the ground.
23USER GUIDE SECTION 4
AUGER
TIP: When removing the auger – back screw the drill (turn it anti clockwise)
for several seconds before removing drill from hole.
4.8 AUGER ALIGNMENT
When drilling, you must keep the auger vertical at all times to avoid uneven holes and
potential damage to the auger. The natural arc of the parent machine arms will push the
auger out of alignment (Fig A). Continuous adjustment is required of the parent machine
arms to maintain vertical alignment (Fig B).
Note: Ensure the cradle arm angle is approx. 30� away from the motor body before
commencing drilling.
24USER GUIDE SECTION 4
AUGER
The angle is controlled using the
bucket crowd ram.
If cradle arm is not distanced from
drill body, it will affect alignment,
and in worst case, could cause
bending of drill.
4.9 DRILLING WITH EXTENSIONS - TELESCOPIC & FIXED
Telescopic extensions enables drilling holes deeper than the Auger length, without the
need to remove the extension to extract the Auger.
DO NOT allow the earth drill to enter the hole as seals can be damaged by spoil being
extracted.
SAFETY FIRST
Whenever earth drill unit components are being assembled or
disassembled from the parent machine ALWAYS work in pairs
(2 skilled operatives).
While fitting components, ALWAYS check parent machine:
• Is in correct working order
• Is parked correctly on flat ground
• Has its hand brake ON, hydraulic circuit locked out and its
engine switched OFF.
25USER GUIDE SECTION 4
AUGER
CHECK that the extension is the
correct model and type to fit the
earth drill unit and Auger.
ENSURE that all earth drill, Auger
and extension connections are clean
before fitting.
USE suitably rated lifting equipment
if required.
When using telescopic extensions
in drilling operations, a length of
timber is required for supporting the
Auger while adjusting the extension.
The timber must be of minimum
dimensions 150mm (6”) deep x 50mm
(2”) wide and long enough to span the
hole being drilled, plus an additional
300mm (12”) length at each end.
FITTING A TELESCOPIC EXTENSION
Note: The telescopic extension hub is bolted to
the extension shaft, DO NOT remove this bolt. The
extension is fixed to the Auger with a pin and linch pin.
The telescopic extension can be fitted before
drilling commences:
• Insert the extension into the Auger, ensuring
that the pin holes line up.
• Fix the extension to the Auger at the top pin hole
(the shortest setting).
• Position the Auger and extension in the vertical
work position and support it so that it cannot fall
over.
• Position the earth drill over the Auger and
extension align the pin holes.
• Lower the earth drill unit onto the extension.
• Insert the extension drive pin.
• Secure the extension drive pin with linch pin.
• Commence drilling.
26USER GUIDE SECTION 4
AUGER
ADJUSTING A TELESCOPIC EXTENSION
To adjust the extension length:
• Lift the earth drill until the Auger flight is clear of
the ground and insert the timber support through the
Auger flight.
• Lower the earth drill until the weight of the Auger and
extension are supported by the timber. Make sure that
the load is distributed equally on either side of the
hole.
• Remove the linch pin and Auger drive pin.
• Lift the earth drill until the desired extension length
is achieved and the holes in the Auger and extension
line up.
Note: The shaft of the telescopic extension has a red
painted portion at the bottom end. When lifting the shaft
out to increase the extension length, the appearance of
the red area above the Auger hub indicates that you are
approaching the longest setting and the end of the shaft.
Careful height adjustment in this area prevents the shaft
coming out of the Auger and having to be lined up and
re-inserted.
• Insert the Auger drive pin.
• Secure the Auger drive pin with the linch pin.
• Lift the earth drill to remove the load from the timber
support.
• Remove the timber support.
27USER GUIDE SECTION 4
AUGER
DRILLING WITH FIXED EXTENSIONS
When the required hole depth is greater than the length of the Auger, an extension
should be used. DO NOT allow the earth drill to enter the hole as seals can be damaged
by spoil being extracted.
SAFETY FIRST
Whenever earth drill unit components are being assembled or
disassembled from the parent machine ALWAYS work in pairs
(2 skilled operatives). While fitting components:
ALWAYS check parent machine:
• Is in correct working order
• Is parked correctly on flat ground
• Hydraulic circuit locked out and its engine switched OFF.
CHECK that the extension is the correct model and type to fit the earth drill unit
and Auger.
ENSURE that all earth drill, Auger and extension connections are clean before fitting.
USE suitably rated lifting equipment if required.
When using extensions in drilling operations, a length of timber is
required for supporting the Auger while removing the extension.
The timber must be of minimum dimensions 150mm (6”) deep x
50mm (2”) wide and long enough to span the hole being drilled,
plus an additional 300mm (12”) length at each end.
FITTING A FIXED EXTENSION
When the hole has been drilled to the point where the top
of the auger comes within 200mm (8”) above ground level:
• Stop drilling.
• Remove the auger from the hole and clear the spoil
from the auger.
• Lower the auger back into the hole so that its weight
is supported and remove the linch pin and Auger
drive pin.
• Lift the earth drill clear of the Auger and slew it to
one side, clear of the hole and set it to a height that
will allow the extension to be fitted easily.
• Position the extension in the vertical work position
and support it so that it cannot fall over.

ALWAYS store the Auger and earth drill securely and safely when removed from the
parent machine taking special care of the hydraulic hoses and connections.
TRANSPORTATION WITHIN THE JOB SITE
ALWAYS operate the parent machine slowly when on site taking great care to avoid
the Auger swinging.
RECOMMENDED: Where fitted use the hitch cradle to support the earth drill unit
when manoeuvring on site.

‘PECKER CIRCUIT’, PRESSURE CAN BE TRAPPED IN THE CIRCUIT WHICH
MEANS THE QUICK RELEASE COUPLINGS ARE VERY HARD TO OPERATE,
OR CANNOT BE OPERATED DUE TO THE PRESSURE.

Drop or disable the dead man control
lever, then turn machines ignition ‘off’.
Pressure can be confirmed to be released,
as quick release couplings should
rotate relative to each other freely and
disconnect easily.

SUMMARY: WHAT IS HAPPENING BY THESE ACTIONS?
Modern excavators have a pressure accumulator built into them. This can be thought
of as a small capacity hydraulic battery.
What we are doing with the above steps, is to use the hydraulic power in the
accumulator, to open or move the spool in the pecker circuit, which releases the
pressure in the hydraulic line.
PROBLEM SOLVING:
If experiencing issues with releasing the pressure:
A. Repeat the above steps several times.
B. Complete the steps within approx. a 30 second period. (Reason – accumulator
pressure can drop over time due to wear or seal leakage. A newer machine will
give you more time to complete the steps etc.)
If pressure cannot be released by this method – contact an MGF fitter.
