08 COMMISSIONING PROCEDURE

WARNING!

NOTE: BEFORE THE DRIVE UNIT IS EVEN CONNECTED TO THE MACHINE ENSURE

THAT THE DRIVE IS FULL OF HYDRAULIC OIL AND THE GEARBOX IS FULL OF GEAR

OIL.

All Impulse planetary drive units are dispatched from the factory full of fluids (hydraulic and

gearbox oil) unless the drive unit is shipped by plane.

1. Once you have determined if the drive unit has gearbox oil in it or requires oil, ensure that the

correct grade and quantity of oil is used. DO NOT RUN THE DRIVE UNIT WITHOUT GEARBOX OIL.

Connect the hydraulic hoses.

WARNING!

NOTE: IF REQUIRED, ENSURE THAT THE CASE DRAIN HOSE IS CONNECTED TO THE

RESERVOIR OF THE MACHINE. IT IS IMPORTANT THAT THE PRESSURE IN THE CASE

DRAIN HOSE IS NOT READING MORE THAN 690KPA (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

IMPULSE DEALER IF THIS OCCURS.

WARNING!

NOTE: TO ENSURE THE BEST MOTOR LIFE, RUN MOTOR FOR APPROXIMATELY

ONE HOUR AT 30% OF RATED PRESSURE BEFORE APPLICATION TO FULL LOAD.

BE SURE THAT THE MOTOR AND GEARBOX ARE FULL OF FLUIDS PRIOR TO ANY

LOAD APPLICATION.

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.
