VX30/VX50 Gen3/ECO50 Vacuum Excavators Operating the Vacuum Excavator 50-13
Step 5: Place Reve
rse Flow Control (2) in Vacuum position. Open Upper Gate/Tank
Inlet Valve.
Step 6: As long
as vacuum hose is connected to the spoil tank and the engine is
running, the vacuum tool will be vacuuming. To stop vacuuming, turn off
engine.
Step 7: When
vacuuming liquids, do not completely submerge vacuum tool in the
fluid. Keeping tool partially out of the fluid allows airflow through the
vacuum tube to move material more quickly to the spoil tank. This technique
is also effective when vacuuming deep vertical distances.
Step 8: When fl
uid level in the spoil tank reaches capacity, the engine automatically
shuts down to prevent overfilling. When this occurs, empty the spoil tank.
Refer to “Dumping Spoil Tank,” p
age 50-19.
Step 9: When
vacuuming dry materials, the Tank Full shutdown sensor does not
function. Stop vacuuming when spoil tank level reaches sight glass (3), or
when debris can be heard circulating in the cyclonic separator.
Step 10: If engine di
d not shut off automatically, follow the Shutdown Procedure, page
23-1, and remove ignition key.
Step 11: D
isconnect hoses. Securely store all tools and hoses before traveling to the
spoil disposal site.
