Unit can now be driven. As unit moves, the water pump will circulate water throughout the
system and back to the tank.
Caution!
The pump systems should never be operated in a gear range greater than indicated
on the dashboard and truck labeling. Failure to heed this caution may result in
severe damage to the water pump or exhauster. Please consult with the factory if
the vehicle gear range is not specified.
Suggestion:
Always carry the handgun and nozzles in the heated cab of the truck when not in
use to prevent freezing.
Note:
All units supplied with cold weather recirculation are equipped with two low water warning
sensors controlled by the “Winter/Summer” Switch in the cab. In cold weather the switch
should be in the “Winter” position. This allows more water to remain in the tank to
accommodate recirculation. During warmer weather, the switch should be in the “Summer”
position, providing more water for hydro excavation operations.
