DANGER The DANGER designation indicates an imminently hazardous situation that, if not avoided, will result in death.
  • Page 9 Safety Precautions - General Information Before You Dig • Service provided in Australia through the website www.byda.com.au. • Never begin work at a new location until the work area has been fully marked for underground utilities. Buried electrical, telephone, cable wires, gas, water and sewer lines are likely to be present. Unintentionally disrupting these hidden hazards while working with your loader can result in dangerous situations and property damage.

    Complete a Risk Assessment Your Digga Planetary Drive is a versatile earthmoving machinery attachment, capable of performing its tasks in a safe and effective manner. To ensure the safety of operators and others, it is important to document the work at hand for hazard and risk.
  • Page 15 Safety - Working with the Attachment NOTE Remember, Personal Protection Equipment (PPE) provides a level of protection during work, but PPE is the last level of harzard control and prevention. Always refer to the hierarcy of hazard control, when planning a safety process. Take Extreme Care When Dealing with Hydraulics - Whilst Assembling, Operating, Maintaining or Performing any work on or near this product.
  • Page 16 Do not make any modifications to your Digga Planetary drive unit. • When making repairs use only authorised Digga service agents and use only genuine Digga parts for the gearbox. For fasteners, hydraulic hoses, or hydraulic fittings, use only properly rated parts.

  • Page 17: Safety - Decal Labels

    Safety - Decal Labels The following section provides a glossary of safety labels found on your Digga Planetary drive unit. These labels are important!

  • Page 22: Commissioning Procedure

    Commissioning Procedure All Digga Planetary drive units are dispatched from the factory full of fluids (hydraulic and gearbox oil) unless a 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.
  • Page 23 Be sure that motor and gearbox are full of fluids prior to any load application. When procuring any hose assemblies for use on your Digga Planetary drive unit ensure that the maximum operating pressure of the hoses is always 25% higher than what the excavator or machine can produce (which the planetary drive unit will be used on).
  • Page 24 Commissioning Procedure Installing your Planetary drive • Remove the shipping banding from around the attachment. • Ensure you have read the identification decal on the drive unit to obtain the maximum flow and pressure ratings, and your hydraulic power source flow and pressure settings are aligned with the requirements of the drive unit.

  • Page 28: Operating Instructions

    Cold Weather Startup Information The information that is contained on this page is an aid to the operation and maintenance of your Digga planetary drive unit in cold weather. When you operate the hydraulic power source in temperatures from 9°C (48°F) to −40°C (−40°F) refer to the operation and maintenance manual of your machine.
  • Page 29 (clockwise) rotation. This is the “digging” position. CAUTION Your Digga Planetary drive is specifically designed for drilling and rotational operation only, it is not a lifting device!
  • Page 30 Operating Instructions • 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 the auger RPM, increase the hydraulic power source's engine RPM. Decrease the hydraulic power source’s engine RPM to decrease the auger RPM.
  • Page 31 For telescopic extensions, use the same method as above, but slide the inner extension back into the auger and pin. NOTE Digga does not accept any liability for injury or damage resulting from the operator using the extension (s) outside the designed operating procedure.
  • Page 32 It is the responsibility of the installer to correctly calculate, plan and execute the installation of the piers to the nominated required torques. Digga does not accept any liability or consequential loss that is incurred from incorrect installation, over torquing or under torquing of piles.
  • Page 33 Operating Instructions Hand mounted use HH units are designed to be light enough to be hand-carried to the screw pilling location and spare the use of a hosting machine, such as an excavator or mini-loader. However, despite their lightweight, HH planetary drive units deploy a massive torque load and must be properly supported during use.

  • Page 34: Maintenance

    Maintenance Oil Change The gearbox oil capacity is shown on a decal on the gearbox for lightweight units. Initial (Bed-in) Oil Change: • The first oil change must be carried out within the first 50 hours of use under moderate operating conditions.
  • Page 35 Maintenance Minimum and maximum gear oil operating temperature for gearboxes HH - ISO EP 320 (Mineral Oil) 120°C (248°F) -9°C (16°F) °C -100 Instructions on how to warm up a drive if operating below 5°C (41°F) can be found in operating instructions section of this manual.
  • Page 36 It is advisable that oil changes are performed by a Digga Authorised Service Agent. Although it is not always possible for many reasons to get this done by a Dealer it is important that the oil is changed at the required intervals.
  • Page 37 Maintenance Procedure for Changing or Re-filling Gearbox Oil Level • Lay the drive unit flat on the ground with the oil fill bung facing up. Using an 8mm (0.31") Allen key remove the bung. To drain oil, turn the drive until the hole is facing down. Allow to drain until all oil has been removed (E).
  • Page 38 NOTE Digga specified ISO EP320 mineral gear oil is specifically for “Extreme Pressure” industrial gearboxes. Oil capacity charts are estimated for a gearbox being filled the first time. When changing the oil, not all oil will drain out, there will always be some residual oil left in the gearbox.

  • Page 39: Spare Parts

    For spare parts of your Planetary drive unit, obtain the serial number engraved on the side of the gearbox flange (see page 18). The serial number allows Digga to trace all production and service records. Ensure all service and maintenance is performed by an authorised Digga service agent and all service records are kept.
