Creating pressure to these nozzles is done through the Throttle Valve. Threading the
Throttle Valve in (picture # 1) will create pressure to either the boom nozzles or the hose
reel. Threading the Throttle Valve out (picture # 2) will bring pressure to the tank(s) and
create agitation. If threading the Throttle Valve in does not create the desired pressure,
check your In-line filter housing and make sure that the O-Ring is present and the
housing is screwed on tight. If desired pressure is still not achieved, pressure adjustments
can be made at the pump (pictured far right). Clockwise turns create more pressure and
counter-clockwise turns decrease pressure.

If optimum pressure is achieved but boom nozzles are dripping, look at either your O-
Rings in your boom nozzles (may not be present or if present may not be seated properly)
or the hose reel valve may be open. Leaving the coil hose valve in the open position will
not allow the 5 psi check ball valves to close immediately when the pump is turned off.
This will create the nozzles to leak and drip for a short period of time upon shutting the
pump off, so make sure that your coil hose valve is turned to the off position if not in use.
Turning on the spray system can be done one of two ways. Your first option would be the
On/Off switch located on the control panel. This would be located on the lower/right side
of the control panel. The second way to turn the spray system on is the foot switch
located on the left side on the Foot Pan. This is the most common way to turn
on the spray system because it allows the operator to keep both hands on the control arms
and drive the unit. By applying pressure on the foot switch with your left foot, the spray
system is turned on. Releasing the foot switch will turn the spray system off.
There is a chrome valve that allows the 25’ Coil Hose to be opened. This is located on the
middle Directo Valve of you sprayer (pictured on opposite page). If not using the Coil
Hose for any applications, leaving the valve in the closed position will help the boom
spray nozzles close (stop spraying) quicker. This will alleviate any dripping from the tips
and potential turf damage (burning turf).
