Spray Bar
The Spray Bar is controlled by the spray bar valve. Open
the main tank valve and close the bypass valve.
Start the engine and increase to full throttle. Open the spray
bar valve. Use the pickup speed to control the rate that
water is applied. The amount of water flowing through the
spray bar can be controlled by partially closing the spray
bar valve or slightly opening the bypass valve. Do not close
the main tank valve. Pump damage can result.
The spray bar covers a maximum swath of 25’. Common
uses include controlling dust on roads and parking lots,
compacting roads and building sites.
Fire Hose
The 25’ fire hose couples to the fire hose valve on either
side of the trailer. Remove the fire hose coupler cap and
quick couple the fire hose. Open the main tank valve,
close the bypass and spray bar valves. Open the fire hose
valve on the side that the hose is attached. The fire nozzle
adjusts from wide spray to straight stream by rotating the
body of the nozzle.
