All D-series planetary gear drive units listed in this manual use ISO EP 320 (mineral oil) gearbox oil
for operating in tropical ambient temperatures. See maintenance section in the operators manual
on gearbox oil level checking as well as the gearbox oils recommended for cold climate
conditions. Technopark Impulse produces many drive units with many different gear set ratios
and as a result don’t list every possible gearbox option and gearbox oil quantity required. See
the maintenance section (page 48) for gearbox oil volume and checking/topping up the
gearbox oil. The gearbox oil quantity is also on the serial tag located between the ears of the
hood.
WARNING!
NOTE: WHEN PROCURING ANY HOSE ASSEMBLIES FOR USE ON YOUR IMPULSE
PLANETARY DRIVE UNIT ENSURE THAT THE MAX OPERATING PRESSURE OF THE
HOSES IS ALWAYS HIGHER THAN WHAT THE EXCAVATOR OR MACHINE (WHICH
THE PLANETARY DRIVE UNIT WILL BE USED ON) CAN PRODUCE.
INSTALLING YOUR HIGH PERFORMANCE PLANETARY DRIVE
1. Remove the shipping banding from around the attachment.
2. ENSURE YOU HAVE READ THE SERIAL TAG ON THE DRIVE UNIT TO OBTAIN THE MAX FLOW AND
PRESSURE RATINGS. Ensure your machine ow and pressure settings are aligned with the
requirements of the drive unit. NEVER EXCEED THE MAX FLOW AND PRESSURE RATINGS AS
WARRANTY WILL BE VOID.
3. Following all standard safety practices and the instructions for installing an attachment as
shown in your machine operator’s manual.
4. Lower the unit to the ground and remove any attachments from the front of the host machine.
5. Attach the quick attach mounting frame or hitch to the host machine as per the machine
manufacturers specications. Ensure the locking mechanisms on the machine are engaged &
the attachment is secure.
WARNING!
NOTE: IT IS IMPORTANT TO MAKE SURE THE LOCKING MECHANISM ON YOUR
QUICK ATTACH IS ENGAGED, THEREFORE LOCKING THE ATTACHMENT ONTO THE
MACHINE.
6. Relieve any pressure from the auxiliary hydraulic system and after making sure there is no
foreign matter on the hydraulic couplers, connect the power and return couplers to the auxiliary
hydraulic system of your machine. The list below shows the most common places to “tap” into
the hydraulic system on various types of machines.
• SKID STEER LOADERS – Auxiliary hydraulic outlets.
• BACKHOES & EXCAVATORS – Auxiliary hydraulic outlets or bucket curl cylinder circuit.
• WHEEL LOADERS – Auxiliary hydraulic outlets or bucket tilt (dump) cylinder circuit.
7. If applicable connect the case drain coupler to the case drain on your machine. If your machine
has a case tap, ensure the case tap is open. Failure to connect the case drain will severely damage
the motor and void all warranty. Case drain hose is already fitted to the units hydraulic motor
and must be unraveled. This case drain hose must return directly to the hydraulic oil
reservoir on the host machine. There can be no valving or restrictions in the line and the
hose must be minimum ½” ID. The loose end of this case drain line must have a fitting fitted to
match the fitting on the host machine.
WARNING!
WARNING: ENSURE THAT THERE ARE NO QUICK RELEASE COUPLERS IN THE CASE
DRAIN LINE OR THE T-CONNECTORS. OPERATION WITHOUT CASE DRAIN WILL
CAUSE MOTOR FAILURE
8. VARIABLE FOOT CONTROL – Excavators used to power drive units must have their auxiliary
circuit controlled with a variable foot control. This foot control gives the operator the ability to
ease the power on and off avoiding shock loading which will cause potential expensive damage
to the hydraulic motor and gearbox.
9. FILTRATION/CONTAMINATION – These units are fitted with a hydraulic motor, therefore require
the oil to be of suitable cleanliness. Ensure hoses are clear of any contamination during
connecting/disconnecting to prevent contaminants entering the hydraulic motor.
10. With the unit lying horizontally on the ground,connect the auger, screw anchor or
extension or core barrel. ENSURE THE AUGER PIN AND SAFETY CLIP ARE INSTALLED
CORRECTLY. The machine is now ready for use.
11. If auguring, check the auger teeth and pilots are not worn. Ensure all worn parts are
replaced. Worn parts will become ineffective and severely diminish the overall
performance of the planetary drive and auger.
PLEASE NOTE: ALTERING,TAMPERING OR DISMANTLING ANY PART OFTHE IMPULSE UNIT
WITHOUT WRITTEN PERMISSION FROM NEXGEN ATTACHMENTS INC. WILL VOID ANY WARRANTY.

09 OPERATING INSTRUCTIONS  COLD WEATHER STARTUP
COLD WEATHER STARTUP INFORMATION
The information that is contained on this page is an aid to the operation and maintenance of your
Impulse planetary Drive Unit in cold weather. When you operate the host machine in temperatures
from 9 °C (48 °F) to −40 °C (−40 °F) refer to the Operation and Maintenance Manual of your machine. It is
dicult to outline the operation and maintenance of a machine that is used in freezing temperatures for
a general publication.The diculty in outlining the requirements is caused by the following conditions:
• The unlimited dierences in weather conditions
• Applications and ground conditions
• And the supplies that are available in your area
In order to provide the best possible guidelines, use the information in this document and
the following criteria: varying factors, recommendations from your machinery dealer, and past
proven practices.
Hints for cold weather
Make sure that you read the information for selecting the correct oils for use in cold
weather. Refer to page 25for details. Prepare the machine for the weather conditions as
instructed in your machines operator manuals.
Procedure for startup in cold weather
• Your Impulse Planetary Drive System is designed to operate within ambient temperatures of 5°C
(41°F) and 30°C (86°F).
• For temperatures below 5°C (48°F) it is recommended to slowly start the drive under no load, at
minimum speed. This will allow warm hydraulic oil from your host machine to circulate through
the hydraulic motor of your drive and slowly bring it to the minimum recommended operating
temperature of of 5°C (48°F).
•Once the minimum temperature has been reached, it is recommended to slowly introduce load
to the output of the drive unit, which in turn will increase the internal gear oil temperature.
Note - The host machines'cooling system and the lubrication system for the engine do not lose
heat immediately upon shutdown. The transmission and the hydraulic system lose heat more
rapidly because of more exposed areas. The Planetary Gearbox & Motor cases cool rapidly, since
the cases do not operate as warm as other compartments. Therefore, after any period of down
time on the machine, ensure you achieve full operating temperature.
OPERATING PROCEDURES – AUGERING
WARNING!
YOUR IMPULSE HIGH PERFORMANCE PLANETARY DRIVE IS SPECIFICALLY DESIGNED
FOR DRILLING AND ROTATIONAL OPERATION ONLY, IT IS NOT A LIFTING DEVICE!
Intended use
This unit is designed for drilling vertical or horizontal holes or rotating piers into the ground. Use
in any other way is considered contrary to the intended use.
After all installation instructions have been completed, safety information read and understood,
and the rest of this operator’s manual has been reviewed, your Impulse Auger Drive is now ready
for use.
1. With the auger raised off the ground and the vehicle engine set at a low RPM, activate the host
machines drive control valve to determine which position the control valve lever must be in to
turn auger in a forward (clockwise) rotation. This is the “digging” position.
2. Before beginning to dig, experiment with auger speed to determine a suitable auger RPM.
Generally in light and sandy soil a high RPM is desirable. In hard, rocky, or frozen soils a slower
RPM is desirable. To increase auger RPM, increase vehicle engine RPM. To decrease auger RPM,
decrease vehicle engine RPM.
3. Raise the Auger Drive so the auger hangs vertically and the drive is clear of the cradle, then
lower the auger into the starting position.
4. Ensure the cradle on your machine is forward and not back. This will keep the Drive clear of
the cradle and allow the auger to move freely from side to side and forward and back. The
pendulum action must not be hindered,otherwise damage / bending of the shaft or auger may
occur. Lower the auger into the ground,ensuring the auger drive does not stall and remains in a
vertical position, start rotation of the auger.
5. As the auger starts to load up with soil, stop the rotation whilst still in the hole and raise the
auger vertically. Move away from the hole, rotate the auger & stop in the forward direction to
remove the soil. DO NOT rapidly engage forward/reverse action to remove soil.
WARNING!
DO NOT RAPIDLY ENGAGE FORWARD REVERSE OPERATIONTO REMOVE SOIL FROM
THE AUGER, THIS CREATES EXCESSIVE PRESSURE SPIKES WHICH WILL ADVERSELY
EFFECT PERFORMANCE AND LONGEVITY OF THE MOTOR.
6. Do not remove the auger at an angle out of the hole, as you will run the increased risk of
bending the auger or shaft.
7. If trying to remove the auger full of material and you experience strong resistance, reverse
the auger slowly whilst raising the auger vertically to assist with removal. Do not pull with the
machine as you may run the risk of shaft damage to the drive.
8. Do not flick the dirt (especially mud or clay) from the auger, as you may run the increased risk
of bending the auger shaft.
9. Keep clearing the auger hole regularly as you drill deeper. This will help prolong the life of the
auger and the wear parts.
*Note: In rock it is recommended to add a slow stream of water to help the performance and life
of the rock teeth.

Excavators – Apply the greatest amount of down force from the main boom. Be aware that the
boom moves in an arc and to maintain a vertical drilling position, you will need
to compensate for this movement by adjusting the dipper arm or moving your
machine backwards or forwards to ensure you are drilling straight. You must
take extreme care when doing this to prevent the auger or screw pile from
bending or pulling flights against the inside of the hole.
All other machines – Ensure the vertical position is maintained when drilling.
DO NOT drill with the Cradle resting against the Drive Unit –This will
damage your Drive unit & Auger
The correct drilling operation is with the Cradle positioned up and
away from the Drive Unit allowing the Drive and Auger to swing
freely left, right, forward & back.
For manoeuvring around the job site the Cradle is positioned so the
Drive unit is resting against the Cradle arm & the loader arms are not
obstructing visibility.
EXTENSIONS & TELESCOPIC AUGER EXTENSIONS – OPERATING PROCEDURE
1. Once you have obtained the maximum depth with the extension & auger you have, raise the
auger out of the hole & clear the soil from the auger. Place the auger back into the hole ensuring
the auger is bottomed out in the hole & the hub of the extension is clear & easily accessible,
remove the auger pin to disengage the auger drive from the auger.
Note - Ensure personal safety at all times, determine if access to the auger hub, once
the auger is in the hole, is safe, if not safe for persons assisting, place boards or covers
across the hole before attempting to reach across to the hub.
Install the additional extension onto the auger drive with pin & safety clip, lower the extension
& attach to the auger with second pin & safety clip. Always ensure people assisting are clear &
visible to the operator at all times.
2. Recommencedrilling. Onceyouhavereachedthemaximumdepth, raisetheauger andextension
out of the hole until the eyelets of the extension are visible & just above the hole. Slide the two
support bars through the two heavy duty eyelets or U brackets welded to the outer extension.
Then remove the pin & section of extension and place away from the hole. Then re-pin back
to the bottom section, take the weight of the rest of the extension & auger on the machine &
remove the support bars. Clear the auger & then keep repeating these steps.
3. For telescopic extensions, use the same method as above, but slide the inner extension back
into the auger & pin.

PROCEDURE
OPERATING PROCEDURES – SCREW ANCHORING (PILE/PIER)
1. Installation is to be performed by a trained and/or certified installer.
2. Connect the manufacturer’s approved adapters to the Planetary Drive head,install the pile in
one continuous motion until the desired depth and torque is achieved.
3. Install pile/pier with a continuous motion.The rate should match the pitch on the pile. Make sure
to apply just enough downward pressure to help the advancement of the pile into the ground,
but not toomuch that you are driving or drilling the pile into the ground. Always maintain
a vertical line so that you do not bend the pile.
All 2 Stage reduction D-series Model drives (D15–D50) specified for anchoring applications must
be fitted with an ECV – Energy Contol Valve (Patented). During the screw anchoring process,
energy builds up in the pile/pier, when the operator stops installation as torque is reached,
the pile/pier temporarily ‘flicks’ back or rotates back forcing energy up the pile/pier, back up
through the gear sets and into the motor, momentarily turning the motor into a pump. The ECV
is designed to protect the motor from this action and essentially grabs the oil and gently bleeds it
back down the hydraulic lines. The sound it makes is a gentle ‘swoosh’, this is how you know the
valve is working.
Note - Inefficiencies occur with machinery that can reduce the torque output, such as heat, cold,
age of machine etc. It is therefore highly recommended that torque monitoring equipment to
keep record of the torque and pressure is installed. Contact Technopark Impulse or your local
Impulse Dealer for further information regarding torque monitoring options.
WARNING!
IT IS THE RESPONSIBILITY OF THE INSTALLER TO CORRECTLY CALCULATE,
PLAN AND EXECUTE THE INSTALLATION OF THE PIERS TO THE NOMINAL
TORQUES REQUIRED. TECHNOPARK IMPULSE DOES NOT ACCEPT ANY
LIABILITY OR CONSEQUENTIAL LOSS THAT IS INCURRED FROM INCORRECT
INSTALLATION, OVER TORQUING OR UNDER TORQUING OF PILES

drive unit.
Resting the drive unit on
the cradle will stop it from
swinging around while
manoeuvring over
uneven terrain.
The cradle allows the operator to angle
the drive up to 90 degrees for easy
connection to augers and anchors.

PROCEDURE TO CHECK THE GEARBOX OIL LEVEL
Unfortunately, there is no way to make a quick visual inspection of the gearbox oil level. The
gearbox is filled to the correct level at the factory. Unless there are clear signs of gearbox oil
leakage it should not require topping up between scheduled oil changes or services.
PROCEDURE TO DRAIN GEAR BOX OIL
The gearbox oil change interval should be carried out in accordance with the requirements set out
in the table on page 25. It is advisable to replace the output shaft seal at the rst oil change as this
is the most important oil change to prolong the life of bearings and gears. The reasoning behind
this is that whilst bedding in, gearboxes can generate ne metallic contamination. This will nd
its way to the lowest part of the gearbox and collect in the output seal thus allowing an abrasive
paste to wear the output seal and the output shaft. It is advisable that oil changes are performed
by a Impulse authorized service agent, however it is not always possible for many reasons to get
this done by a dealer however what is important is that the oil is changed at the required intervals.
REMEMBER TO CONSIDER THE ENVIRONMENT, STATE/PROVINCIAL AND
FEDERAL LAWS RELATING TO DISPOSAL OF OIL. DUMPING AND SPILLAGE OF
OIL ONTO LAND, STORM WATER OUTLETS AND WATERWAYS IS ILLEGAL. OIL
MUST BE DISPOSED OF BY PROFESSIONAL WASTE DISPOSAL OR RECYCLING
SPECIALIST.
1. Ensure that the gearbox is stable, secure,safe to work on and that the drive unit is vertical.
Also, that there is an appropriate sized drip tray to catch the drained oil.
2. Before commencing to drain any oil, check the serial tag of the unit to determine the quantity
of oil which the gearbox holds. This will indicate the quantity of oil which has to be replaced
into the gearbox and size of bucket needed to contain the oil. Remove the drain plug from the
output housing. This will allow the bulk of the gearbox oil to drain out (this will not drain the
gearbox entirely). The lower section of the output housing, below the plug will still contain
some oil.
3. To drain the remaining oil, lay the drive unit on it’s side with the bung-hole facing down.
4. Once all the oil has been drained follow the procedure on the following page to refill the oil.
PROCEDURE FOR CHANGING OR RE-FILLING GEARBOX OIL LEVEL
WARNING!
NOTE: IF YOUR UNIT IS LEAKING OIL AFTER YOU HAVE PERFORMED THE DAILY
CHECKS,CONSULT YOUR LOCAL AUTHORIZED SERVICE AGENT.
1. Lay the drive unit flat on the ground with the oil fill hole facing up. Usean 8mm Allen key
to remove the bung. To drain the oil, turn the drive until the hole is facing down. Allow to
drain until all the oil has been removed.
60º
2. Rotate the unit until the oil ll hole is sitting between 60º – 70º from horizontal.
60º
3. Once the ller hole is at approx 60º the oil should be sitting at the base of the ller hole thread.
60º
4. If the oil level is too low to reach the thread it should be topped up. Rotate the unit so the filler
hole is sitting at the top and add oil. Repeat steps 2 – 4 until you have achieved the correct level.
Note that the oil takes time to work it’s way through the gearbox. Allow time for it to settle once
it has reached the bung-hole. Then check the level again until all seepage has occurred.

WARNING!
Please Note: Oil capacity charts are estimated for a gearbox being lled the rst
time. When changing the oil, not all oil will drain out, there will always be some
resididual oil left in the gearbox. Follow the procedure to ll the gearbox, using
the oil capacity charts as a guide only.
