pump leveR installation: All hardware necessary for pump lever installation is
included with the sprayer. The pump lever (C) should be installed as follows: place lever
handle (C) onto the shaft (A). Align bolt holes and install the two bolts (E) and washers
(F); then tighten. To install pump lever on the opposite side, remove the stop plate (D) and
washer, install the pump lever as above. The stop plate (D) should be mounted on the inner bolt hole with the
closed end of the stop plate pointing downward on the opposite side of the pump shaft.

Push the nozzle body (3) out of the retaining nut (2). The filter
with gasket (4) will come out with the body. To reinstall the
nozzle, reverse the above instructions.

assembly instRuctions foR Wand

1. Insert wand into shut-off valve as shown.

2. Tighten the screw cap clockwise onto the shut-off valve.

sHouldeR stRap installation:

The top of the shoulder straps are pre-attached to the sprayer by means of a buckle. The lower end of the straps
are attached by fastening the strap hooks to the metal frame between where frame exits the plastic tank and makes
a bend.

filling:

Mix the spray formula and the proper volume of water in a separate container. Pour the mix through the filter
basket in the tank opening. This keeps debris from entering sprayer. Add 2 or 3 gallons of spray formula mix. Pump
the sprayer handle to prime the pump and fill the pressure cylinder. The volume of liquid in formula mix tank will
appear to decrease as the pressure cylinder is filled. Liquid will flow through the top of the pressure regulator
when the cylinder is completely full. Add the remaining formula mix to the tank. Remember that it’s not necessary
to completely fill the sprayer tank each time. Mix only the amount needed to get the job done.

Always read and follow manufacturer’s instructions printed on the product label. This can save money and help
prevent crop and environmental damage.

spRaying:

Prime the pump with rapid pump strokes. When you feel very firm resistance, the pressure chamber is filling with liquid.
With repeated piston strokes, the air in the pressure chamber is slowly compressed. By pressing the hand lever, the valve
opens, and liquid is forced through the nozzle. The shut-off valve has a retaining clip which keeps the valve in the “OPEN”
position for continuous operation. Pump using the end of the pump handle, as it is less fatiguing. The volume of liquid
delivered varies with the working pressure which should be as high as needed to ensure an adequate spray pattern for each individual
application.

NOTE: Should the pressure drop very quickly, drain the tank completely and pump without liquid. By this procedure, the air chamber is
refilled with the required volume of air. It is advisable to pump the tank completely empty from time to time.
