10 Commissioning Procedure
Installing your Planetary drive
• Remove the shipping banding from around the attachment.
• Ensure you have read the serial tag on the drive unit to obtain the maximum ow and pressure ratings,
and your machine ow and pressure settings are aligned with the requirements of the drive unit. Never
exceed the maximum ow and pressure ratings as warranty will be voided.
• Follow all standard safety practices and the instructions for installing an attachment as shown in your
machine operator’s manual.
• Lower the unit to the ground and remove any attachments from the front of the host machine.
• 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.
• 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.
• 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 tted to the units 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 inner diameter must be minimum 1/2"
(12.7 mm) . The loose end of this case drain line must have a tting tted to match the tting on the
parent machine.
