3.5 Activating UHP System
& Setting Pressure
UHP Activation Option A:
1. Activate the truck and hydraulics system (refer
to Truck & Accessory Hydraulic System Startup
Procedure section 3.4).
2. Turn the MODE switch on.
3. Make sure the clean water supply valve is open
and turn the CHARGE PUMP switch on. Moni-
tor the charge water pressure gauge. Charge
water pressure should rise to 35–70 PSI (2.4-
4.8 BAR) within 10 seconds.
NOTICE:
IF NO CHARGE WATER PRESSURE OR A LOWER PRESSURE
IS INDICATED, THERE IS A PROBLEM THAT MUST BE
CORRECTED BEFORE OPERATIONS CAN CONTINUE.
4. With the charge pump activated, check the
water flow at the UHP pump stuffing boxes.
A steady stream of water should be flowing
to cool and lubricate the packing. Adjust the
metering valves if necessary.
5. Select “D” (DRIVE) on the truck transmission.
Wait until 4 4 is displayed on the transmission
LED.
6. When 4 4 is displayed, the truck has been
successfully shifted into WORK mode. The UHP
pump and vacuum blower are activated and
ready for the operator to set the pressure and
test the waterblasting system.
CAUTION
THE UHP PUMP IS DIRECTLY DRIVEN BY THE OMSI PTO
AND WILL BE DAMAGED IF THE PTO SWITCH IS ACTIVATED
WITHOUT THE CHARGE PUMP SWITCH ON. ALWAYS MAKE
SURE THE HYDRAULIC SYSTEM IS ACTIVATED AND THE
CHARGE PUMP SWITCH IS ON BEFORE ENGAGING 4/4.
