The Chapin 3 Gallon Stand N Spray No Bend Sprayer (29003) is a great sprayer, with a extended pump to make pumping easy and all of the features that Chapin puts into their sprayers. The extended pump comes up 3 feet, allowing you to pump the sprayer without bending down. The features that come standard with any of Chapin's sprayers are: Nitrile seals that hold the sprayer together, a SureSpray Anti-clog Filter keeping contaminates out of the sprayer, a translucent polyethylene tank that is not damaged by the majority of herbicides, insecticides and fertilizers and will last for a long time, ergonomic handle for easy pumping for an extended period of time, a pressure relief valve to remove any compressed air from the sprayer before filling the sprayer and a splash guard to protect you from any unwanted release of chemicals. This sprayer comes with an adjustable brass nozzle.
Insure the tool holder is assembled to the tank adapter before mounting the discharge assembly. The Tool Holder snaps into the groove of the tank adapter.
Insert the outlet tube portion of the discharge assembly into the tank adapter.
Firmly insert the outlet tube portion into the tank adapter leaving no gap between the tank adapter and outlet tube adapter. Firmly tighten the retaining nut to the tank adapter.
2. Nozzle / Extension Wand
Attach nozzle to shut-off handle or extension wand, depending on the style of extension wand included with sprayer. (Refer to images on the manual attached)
The filter helps prevent clogging while spraying. It is located on the end of the outlet tube inside your sprayer tank. To clean filter, remove the discharge assembly from the tank. Make sure the filter is positioned at the bottom of the tank as pictured.
Note: Filters are not supplied with deck sprayers.
4. Shield Attachment to Wand
Snap shield onto wand as shown. Using the spray shield will help protect your plants etc. from over spray. (Not all models are provided with spray shield).
5. Pre-Use Check
Check tightness of hose nut to be sure hose is securely attached to the tank outlet.
Inspect hose for deterioration, cracks, softness, or brittleness. If any of these conditions are found, replace hose before using. Replace with original manufacturer’s parts only.
Remove pump (see Filling, Pressurizing and Spraying Instructions), inspect interior and exterior of tank for signs of deterioration of body and bottom. Any sign of deterioration indicates possible tank weakening and could result in explosive bursting under pressure. If any of these signs are found, discard tank immediately and replace. Do not attempt to patch leaks, etc., as this could result in serious injury.
Follow Filling, Pressurizing and Spraying Instructions, except use water only (Pump plunger 10-20 strokes and inspect for leaks).
Direct shut-off away from you and open to make sure discharge is not clogged.
If unit passes this test, release pressure (see Pressure Releasing Instructions), empty tank, and proceed with Filling, Pressurizing and Spraying Instructions.
Inspect all metal parts including the wand, nozzle and fittings for rust, corrosion and pitting. If any of these conditions are found, replace affected part with original manufacturer’s part before using.
Turn pump handle counterclockwise and remove pump.
