MAIN HYDRAULIC SYSTEM
STATIONARY AND TRUCK MOUNTED VERTICAL MIXERS
QUICK REFERENCE INFORMATION
Thank you for your investment in a Kirby hydraulic driven mixer. With proper care and service you
can extend the life of the hydraulic system.
Your system is equipped with two (2) Sauer-Sundstrand Series 90 axial piston pumps, two (2)
Parker/VOAC variable displacement hydraulic motors Series V14 and two (2) Fairfield planetary
gearboxes.
In order to ensure hydraulic system efficiency only fresh, clean oil should be added to the hydraulic
tank.
ALL
hydraulic oil that is added to the system
must be filtered
through a 10-micron filter to
ensure oil cleanliness. If any lines are damaged, unfastened or replaced,
extreme
care must be
taken to prevent dirt from entering the hydraulic system. All open lines should be capped. Filter
indicator should be checked regularly and the filters should be replaced if indicated, or as hours of
use require. When replacing the filters always replace O-ring on canister.
Kirby Manufacturing
recommends that only authorized
Kirby
filters be used for replacement. The
filters used must be at least a 10-micron filter. Oil specifications are Pennzoil AW68.
It is critical that proper maintenance and filter changes be made on a regular basis. Warranty is based
on the regular maintenance of your system. Not changing your oil and filters properly and within the
time frame given
WILL VOID YOUR WARRANTY
. All filters should be kept clean and free of
foreign contaminants when replacing to avoid oil contamination.
All hydraulic filters and all planetary gearbox oil should be changed after the first
initial 50 hours
of use. Thereafter, all hydraulic filters should be changed every 500 hours. Use the reservoir filter
gauges, located on the top of the hydraulic fluid reservoir, to help determine when the next filter
change is necessary.
The first oil change on the planetary gearboxes should occur after
50 hours
of use. Thereafter, oil
changes should occur every
1,000 hours.
