Most vacuum truck operation requires two or more operators. It is very common for two or more operators to be required to vacuum debris, dump the debris, clean the vacuum truck, and maintain the vacuum truck. Because of this, teamwork is very important.
Before beginning vacuum operations, you will need to start the truck. One operator will need to climb into the cab of the truck and be sitting safely in the drivers seat.
- Ensure that the parking brake is engaged by pulling the yellow diamond shaped knob located on the dashboard straight out.
- Verify that the truck is in neutral. If the truck is not in neutral, push down on the slutch and put the truck in neutral.
- Place the key in the ignition and turn once to engage the horn signal which will blow 3 times.
- After the horn has blown 3x, press down on the clutch and turn the vehicle on. You will hear the horns blow 3x more.
- While the clutch is still pressed, flip the “Blower Mode” switch on. You will see the LED on the switch light up when it has been engaged.
- While the clutch is still pressed, wait for the green “Road Mode” switch below the parking break to pop out. This indicates that the transfer case has shifted.
- If hudraylics are required (boom, sludge pump, etc.), flip the PTO (power takeoff) switch on. You will see the LED on the switch light up when it has been engaged. This will engage the hydraulic power to the unit.
- While the clutch is still pressed, select high range on the gear shift lever and shift the transmission into the proper gear as indicated on the red dash mounted indicator tag. Typically, high gear will be ninth gear. Slowly release the clutch pedal. You will hear the blower engage.
The blower unit is now operational and running.
