8 COMMISIONING PROCEDURE

Commissioning Procedure for SAI TF2.5 (single speed) hydraulic motors.

NOTE: BEFORE THE DRIVE UNIT IS EVEN CONNECTED TO THE EXCAVATOR ENSURE THAT THE DRIVE IS FULL OF HYDRAULIC OIL AND THE GEARBOX IS FULL OF GEAR OIL.

All Digga planetary drive units are despatched from the factory full of uids (hydraulic and gearbox oil) unless this warning decal is attached.

The decal is only applied in special circumstances, for example if a drive unit needs to be air-freighted to the customer. Air transportation regulation prohibits

certain uids from being air-freighted.

If there are no uids in the drive unit at the time of despatching, then the decal DE-000127 will be applied to the drive unit.

1. Once you have determined if the drive unit has gearbox oil in or requires oil, ensure that the correct grade and quantity of oil is installed. DO NOT RUN THE DRIVE UNIT WITHOUT OIL. Connect the hydraulic hoses to the excavator. If the

customer has ordered the optional Pressure Di󰀨erential Kit and the Diggalign Kit, then there will be 2 electrical harness

to connect. When looking into the access hole in the hood, the hose to connect to the V1 port on the valve block or manifold is the inlet hose (LHS). The hose to connect to V2 port of the valve block is the outlet hose (RHS). (See Diagram

on page 19 and page 20).

2. The case drain hose is already tted to the hydraulic motor and needs to be connected to the hydraulic line which returns to the

hydraulic tank of the excavator.

NOTE: ENSURE THAT THE CASE DRAIN HOSE IS

CONNECTED TO THE RESERVOIR OF THE EXCAVATOR.

IT IS IMPORTANT THAT THE PRESSURE IN THE CASE

DRAIN HOSE IS NOT READING MORE THAN 100PSI

WHILST OPERATING AND THAT A CONSISTENT

TRICKLE OF HYDRAULIC OIL IS BEING RETURNED TO THE EXCAVATOR RESERVOIR. INTERMITTENT AND SPURTS OF FLOW FROM THE CASE DRAIN HOSE

ARE NOT STANDARD DESIGN SYMPTOMS. PLEASE CONSULT A DIGGA DEALER OR DIGGA AUSTRALIA

SERVICE IF THIS OCCURS.

NOTE: TO ENSURE BEST MOTOR LIFE, RUN MOTOR FOR APPROXIMATELY ONE HOUR AT 30% OF RATED PRESSURE BEFORE APPLICATION TO FULL LOAD. BE SURE THAT MOTOR AND GEARBOX ARE FULL OF FLUIDS PRIOR TO START UP.

NOTE: All Single Speed High Powered planetary drive units use Castrol Alphasyn EP320 (standard) Synthetic gearbox oil for operating

in tropical ambient temperatures. See maintenance section in the operators manual on gearbox oil level checking as well as the alternate

gearbox oils recommended for cold climate conditions. Digga produce high powered drive units with three di󰀨erent gearset ratios. See the

maintenance section for gearbox volume and checking/topping up the gearbox oil.

8 COMMISIONING PROCEDURE

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. Follow 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 manufacturers specications. Ensure the locking mechanisms on the machine are engaged & the attachment is secure.

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.

• BACKHOES & EXCAVATORS - Auxiliary hydraulic outlets or bucket curl cylinder circuit.

• WHEEL LOADERS - Auxiliary hydraulic outlets or bucket tilt (dump) cylinder circuit.

7. Route the hoses in such a fashion as to avoid pinching or chang. Be sure the two hydraulic hoses are long enough to perform at the full range of the auger drives operating motion. HIGH PRESSURE HOSES A & B - Route the hoses in such a fashion as to avoid

pinching or chang.

8. The hydraulic block valve with pressure relief has 2 capped SAE 1 threaded ttings or code 62 ange ports onto the motor manifold if no pressure relief is supplied. We recommend that high pressure hoses A & B should be custom made and tted by a Qualied Hose Assembler/Fitter. We also recommend the use of hoses rated to at least (350 Bar/5000 psi) working pressure. Hose size is determined by Machine ow rate and should be calculated by the Qualied Hose Assembler/Fitter. Hoses A & B are normally

connected to the Auxiliary lines on the parent machine.

8 COMMISIONING PROCEDURE239 OPERATING INSTRUCTIONS - COLD WEATHER STARTUP

9. Connect the case drain to the case drain on your machine. If your machine has a case tap, ensure the case tap is turned on.

Failure to connect the case drain will severely damage the motor and void all warranty. The Case Drain hose is already tted

to the unit Hydraulic motor and must be unravelled. This Case drain hose must return directly to Hydraulic Oil Reservoir on the Parent 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 tting tted to match the tting on the Parent machine.

WARNING: ENSURE THAT THERE ARE NO QUICK RELEASE COUPLERS IN THE CASE DRAIN LINE OR T-CONNECTORS. OPERATION WITHOUT CASE DRAIN WILL CAUSE MOTOR FAILURE

10. VARIABLE FOOT CONTROL - Host machines used to power High Powered PD and SD 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 o󰀨 avoiding

shock loading which will cause potential expensive damage to the Hydraulic motor and Gearbox.

11. FILTRATION/CONTAMINATION - All High Powered PD and SD Drive units are tted with Piston Hydraulic Motors which require ltration of 10 micron tted to both A & B pressure hoses. We recommend these lters be permanently tted to the

Drive unit so any contamination entering the system while connecting/disconnecting hoses is caught before entering the hydraulic motor.

12. 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.

13. If augering, check the auger teeth and pilots are not worn. Ensure all worn parts are replaced. Worn parts will become ine󰀨ective

and severely diminish the overall performance of the Planetary Drive and Auger.

PLEASE NOTE: ALTERING, TAMPERING OR DISMANTLING ANY PART OF THE DIGGA UNIT WITHOUT WRITTEN PERMISSION FROM DIGGA WILL VOID ANY WARRANTY.

PM-000145 - PD/SD HIGH POWERED PLANETARY DRIVE MANUAL - MARCH 2019

COLD WEATHER STARTUP INFORMATION

The information that is contained on this page is an aid to the operation and maintenance of your Digga High Powered 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 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 gearbox oils for use in cold weather. Refer to page 33 for detail. Prepare the machine for the weather conditions as instructed In your machines operator manuals.

PROCEDURE FOR STARTUP IN COLD WEATHER

• Your Digga Planetary Drive System is designed to operate within air temperature 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 5°C (48°F).

• Once the minimum temperature has been achieved it is recommended to slowly introduce load to the output of the drive unit, which in turn will increase the internal gear oil temperature.

N.B. 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 temperatures through following start up instructions. Thick oil can also cause high case pressures which in turn cause shaft seal problems.

9 OPERATING INSTRUCTIONS - AUGERING

OPERATING PROCEDURES - AUGERING

YOUR DIGGA 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 holes, core barreling 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 DIGGA Auger Drive is now ready for use.

1. With the auger raised o󰀨 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 vertical and the drive is clear of the cradle, then lower the auger into the starting position.

4. Ensure the crowd 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 spoil, stop the rotation whilst still in the hole and raise the auger vertically. Move away from the hole, rotate the auger & stop, rotate the auger & stop in the forward direction to remove the spoil. DO NOT rapidly engage forward/ reverse action to remove spoil.

PM-000145 - PD/SD HIGH POWERED PLANETARY DRIVE MANUAL - MARCH 2019

9 OPERATING INSTRUCTIONS - AUGERING

DO NOT RAPIDLY ENGAGE FORWARD REVERSE OPERATION TO 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 on 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 ick 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 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 ights against the inside of the hole.

All other machines – Ensure the vertical position is maintained when drilling, screw piling or core barrelling.

9 INSTALLATION AND OPERATING INSTRUCTIONS - EXTENSIONS

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 spoil 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. 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 persons assisting are clear & visible to the operator at all times.

2. Recommence drilling. Once you have reached the maximum depth, raise the auger and extension 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. Either 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.

DIGGA DOES NOT ACCEPT ANY LIABILITY FOR INJURY OR DAMAGE RESULTING FROM THE OPERATOR USING THE EXTENSION(S) OUTSIDE THE DESIGNED OPERATING PROCEDURE

PM-000145 - PD/SD HIGH POWERED PLANETARY DRIVE MANUAL - MARCH 2019

9 OPERATING INSTRUCTIONS - SCREW ANCHOR

OPERATING PROCEDURES - SCREW ANCHORING (PILE/PIER)

1. Installation is to be performed by a trained and/or certied installer.

2. Connect the manufacture’s approved adapters to the Planetary Drive head. As the pressure builds & the torque increases, 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 too much that you are driving or drilling the pile into the ground.

High Powered PD and SD Digga drives are only tted with an ECV - Energy Contol Valve (Patented) as an “option” and designated

as “SV” (see page 6). During the screw anchoring process energy builds up in the pile/pier and when the operator stops installation

when torque is reached, the pile/pier temporarily ‘icks’ back or rotates back forcing energy up the pile/pier back up through the

gearsets 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.

N.B Ine󰀨eciences 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 Digga or your local Digga Dealer for further information regarding torque monitoring options.

IT IS THE RESPONSIBILITY OF THE INSTALLER TO CORRECTLY CALCULATE, PLAN AND EXECUTE THE INSTALLATION OF

THE PIERS TO THE NOMINATED TORQUES REQUIRED. DIGGA DOES NOT ACCEPT ANY LIABILITY OR CONSEQUENTIAL

LOSS THAT IS INCURRED FROM INCORRECT INSTALLATION, OVER TORQUING OR UNDER TORQUING OF PILES.

PROCEDURE TO CHECK THE GEARBOX OIL LEVEL

Unfortunately, there is no provision to make a quick visual inspection of the gearbox oil level. The gearbox is lled to the correct level at the

factory. Unless there are clear signs of gearbox oil leakage it should not require topping up between scheduled services.

PROCEDURE TO DR AIN GEAR BOX OIL

The gearbox oil change interval should be carried out in accordance with the requirements set out in the table on page 32. 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, gears and seals. 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. It is advisable that oil changes are performed by a Digga Authorised 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 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 recycle specialists.

1. Ensure that the gearbox is stable, secure and safe to work on prior and that the drive unit is vertical and that there is an appropriate sized drip tray (Item no.5) to catch any oil spillage.

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 size of the drip tray needed to contain the oil as well as the quantity of oil which has to be replaced in into the gearbox. Remove the drain plug (item 1) from the output housing. This will allow the bulk of the gearbox oil to drain out to an appropriate size drum or bucket. (this will not drain the gearbox entirely and therefore the output shaft seal must be removed to totally drain all the gearbox oil. Also this lower section of the output housing is usually where most foreign particles settle).

3. To drain the remaining oil which is below the drain plug level ensure that there is a drip tray to catch the oil spillage once the seal is removed.

4. Proceed to remove the socket head cap screws which attach the seal protector to the output housing and remove the seal protector.

5. The output shaft seal can then be pried out.

6. The oil will dump into the drip tray.

7. Usually the inside of the seal will collect a sludge build up. Proceed to clean the seal or replace if it appears damaged.

PROCEDURE FOR FILLING GEARBOX OIL LEVEL

• Ensure that you are using the correct grade gearbox oil for the ambient temperature that the drive unit will be operating in. (See page 33)

• Ensure that you have checked the serial tag to determine the quantity of oil that the gearbox holds. (See page 31 for serial tag location)

• Ensure that the gearbox is horizontal and the drain plug facing vertically up. (Image 1)

• Tilt the gearbox at approximately 45 degrees to the horizontal by lifting the output shaft end. (Image 2) This should allow the correct volume of oil to be decanted into the gearbox. If the gearbox oil starts to weep out the ller hole, before reaching the required quantity, then increase the tilt angle of the gearbox and continue to decant oil until the correct quantity is applied.

1. Lay the drive unit at on the ground with the oil

ll bung facing up.

NOTE: IF YOUR UNIT IS LEAKING OIL AFTER YOU HAVE PERFORMED
