The filters are critical to the proper operation of
the Ultra-High Pressure water system. They should
be checked daily and changed when the charge
pressure drops to 35 psi (Refer to filter change
procedure in Maintenance section of this manual).
Dirty charge water filters are the number one
reason for low charge water pressure.
Operating with dirty filters can cause:
• Unwanted particles forced through the filter
resulting in premature failure of the parts.
• Cavitation in the Ultra-High Pressure pump
which will result in damage to the pump.
• Reduced flow of lube water to the packing seals
which could damage the seals.
Remember that the filters can be under pressure.
Always make sure the UHP pump is shutdown,
the CHARGE PUMP switch is OFF, the truck PTO
disengaged and the pressure has been bled from
the system before removing the filter caps.
Always thoroughly flush the filter canisters and
charge water system when the filters are changed
and before activating the Ultra-High Pressure sys-
tem. A purge valve located on the low pressure
(charge water) side of the pump can be opened to
purge the system after a filter change or to flush
the charge water side of the pump if the system
becomes contaminated.
CAUTION
LOW CHARGE WATER PRESSURE CAN qUICKLY DAMAGE
THE UHP PUMP. THE OPERATOR MUST MONITOR THE
CHARGE WATER PRESSURE CLOSELY AND IMMEDIATELY
SHUTDOWN THE UHP PUMP, WATER BLASTING SYSTEM
AND CHARGE WATER PUMP IF LOW CHARGE WATER
PRESSURE IS INDICATED.
USE THE FOLLOWING PROCEDURE TO SHUTDOWN WATER
BLASTING SYSTEM AND CHARGE WATER PUMP:
• Press the EMERGENCY STOP button on
the skid engine control panel to shutdown
the auxiliary engine, uhp pump and water
blasting system.
• Stop the truck
• Turn the charge pump switch off
• Return the truck engine speed to idle
•
Disengage the truck pto to shutdown the
hydraulic system
• Set all speed dials to 0 and set the park-
ing brake
