Maintenance Schedule - Pressure Tech Turret Series Maintenance Manual

DAILY
Check the pressure difference between input and output gauges on the filter body (part # 610027).
Pressure difference should not be greater than 5 PSI while the unit is in operation, anything over
this indicates the bag may need to be replaced. UNDER NO CIRCUMSTANCES should the output
gauge should read negative pressure (vacuum) as that condition might cause pump to fail. A
pressure difference or negative pressure is a sign that the filter bag needs to be changed. Always
use 5 micron bag filter, a less fine filter will let unwanted particles pass through and possibly
damage the pump. Make sure to clean the filter vessel completely before installing a new filter
bag. When putting the new filter bag in, make sure that it is seated all the way down and that the
filter ring makes tight contact with the vessel gasket. Make sure that the vessel lid is latched
properly. Open the bleed valve on the top of the filter vessel (part # 610016). Do not start the
pump unless the filter vessel is full of oil and there is a solid stream of coolant coming out of the
bleeder line through the provided 1/4'' clear hose (this line returns to the machines oil tank). This
will purge air pockets in the hydraulic system.
WEEKLY
Clean the machines main coolant tank by removing all chips and debris. A dirty holding tank will
cause the filter to clog prematurely. The weekly maintenance schedule is a recommendation and
may vary from application to application. When cutting aluminum you may find that the filter bag
clogs faster than when cutting stainless steel. Also, three shifts of operation a day vs one, may
require additional attention and frequency of maintenance.
SPECIAL NOTES
• During pump operation, make sure that oil based coolant does not create a lot of foam.
Contact your coolant supply company to get an additive that prevents foaming. Check and fill
the machine reservoir as needed.
• When turning the unit on frequently in your program (more than 3 times per minute)
change your program so that you alternate the line being used with an interval of at least 2
seconds between. This will keep the pump running constantly. Frequent starting and stopping
puts unnecessary load on the unit.
• Pay extra attention to the level of oil in the pump head. Running the pump unit with no hydraulic
oil will cause the pump to fail.
