Adjusting The Operating Pressure - Craftsman CMXGZBF7124533 Instruction Manual

Step 9: (fig. 9 & 10)
1. Attach the sprayer to the tractor hitch and connect
the wiring to the tractor battery. The red wire must be
connected to the positive post on the battery or to
the "HOT" connection on a tractor switch or ammeter.
The brown wire may be grounded or connected to the
negative battery post.

Before Starting
• It is important to test the boom and spray gun with
plain water before using chemicals. This will enable
you to check the sprayer for leaks and to set the spray
pattern and nozzle pressure. If a leak should occur,
thread tape may be used to better seal the leaking
fitting.
operator on-off Switch
• This switch is connected in line to the wiring assembly
and turns the pump motor on or off
Pump Pressure Switch
• The pump is equipped with a pressure switch. The
pressure switch will temporarily turn off the electrical
power to the pump at a factory predetermined high
pressure point of 60 PSI. If the flow demand is very low,
the pump may repeatedly reach this high pressure point
and the switch will cause "cycling" (the pump cycles on
and off rapidly). This is not a problem unless the pump
is subject to continuous rapid cycling for long periods
of time.
Connect to 12 volt batteries only

on-off adjustment of Boom nozzles
• The sprayer is equipped with a "Y" fitting containing
a boom valve and a bypass valve. The boom valve
turns the flow on or off to the boom nozzles. Open
it completely when spraying with the boom. Close it
completely if you wish to use only the spray gun..

adjusting the operating Pressure

• The bypass valve on the "Y" fitting controls the flow
to the hose that returns fluid to the tank. The amount
of flow through this hose determines the operating
pressure when the boom or the spray gun is in use.
+
Adjust the bypass valve to obtain the desired spray
pattern. If misting occurs, open the bypass valve more
until the misting is eliminated..
adjusting the Spray gun nozzle
• Turn the nozzle on the spray gun to adjust the spray
from a cone shaped fine mist to a straight stream.
Control the spray gun operating pressure with the
bypass valve on the "Y" fitting. Maximum spray gun
pressure can be attained when the boom is shut off...
Setting the Boom for Spraying
• The correct positioning of the boom places the nozzles
approximately 40" apart and 14" above the ground. This
gives a spray width of approximately 80" with a slight
center overlap. See figure 11.
• Slide the boom bars out to the ends of the slots.
• Swivel the boom bars until the nozzles are
approximately 14" above the ground.
• Make sure the nozzles are adjusted so that the openings
point straight down..
