Operation of your S15 Sprayer
The S15 sprayer is designed to be simple to use, easy to operate, and provide years of accurate spraying. The S15 is the latest development
from Earthway Products, Inc., a world leader in the manufacture of broadcast spreaders, seeding tools, and sprayers.
Calibration
The S15 is supplied with three different nozzle options. The table below shows the characteristics and performance of the supplied nozzle
options at the eight different height setting of the DCV holder.
Initial Start-up Procedures
Before the first use, partially fill the tank with clean water to test the spray. If it fails to spray, the pump may require priming or the DCV
rubber valve could be immobile. To fix the DCV, loosen the cap on the DCV to unseat the rubber valve inside and then retighten. To prime
the pump, select TRANSPORT and then push for a short distance. Now, select SPRAY and test. Repeat if necessary until a spray is
achieved. If unit leaks from the nozzle, remove the cap on the DCV, wipe off the top of DCV body to remove any debris, and then replace
the cap and tighten.
Before use
Before using any liquid products always read thoroughly the manufacturers product label, to ensure correct dosage and proper handling of
the product being applied through the applicator. Use the correct Safety Equipment as directed by the chemical manufacturer.
;
Check that the applicator has been thoroughly cleaned from its previous use and that both the nozzle outlet and the handgun line (if
included) have been washed thoroughly.
;
Always spray on a day where wind is minimal. It can be unsafe and inaccurate if spraying is undertaken in windy conditions.
;
Always wear appropriate safety clothing when the sprayer is being used. Refer to manufacturers instructions, or contact your supplier
of the product being applied for safety recommendations.
;
Make sure the tires are properly inflated to 20 psi.
How to use ~
Walk behind spraying
Practice before use
It is recommended for first time users of the S15, that the user familiarizes themselves with the workings of the sprayer. By simply putting
water in the spray tank and spraying it out onto a dry tarmac surface the operator will very quickly familiarize themselves with the workings
of the machine. Make sure the spray tank is then emptied of water before further use. Make sure the handlebar is locked into place and the
wing nuts are securely tightened.
;
Choose the correct nozzle of the three nozzle options that is suitable for the product being applied. (See calibration chart above)
;
Ensure the SPRAY (ON) / TRANSPORT (OFF) lever on the dashboard is in the TRANSPORT position. The TRANSPORT
position is with the lever over to the right side when standing behind the handlebars of the machine.
;
Make sure the tank is clean and there is no chance of remnants or deposits from a previous spray task being left in the tank.
;
With the tank clean, fill the tank with the required volume of liquid for the designated spray task, making sure the product being used is
mixed and being applied in accordance with the manufacturers instructions.
;
With the control lever is in the TRANSPORT (OFF) the machine can be safely pushed to the area where spraying is to be carried out.
;
Locate the sprayer at the point at which spraying needs to commence. Lift the machine up off the stand, so the body of the machine is
parallel with the ground (see example drawing in the center of the next page). To spray simply turn the control lever (ON/OFF) over to
the left side (SPRAY POSITION), and walk forward at a brisk walking speed 2 to 3 MPH is recommended.
;
To stop the spray turn the ON/OFF LEVER back to the right side (TRANSPORT POSITION). NOTE: When the SPRAY/
TRANSPORT lever is at the right side (TRANSPORT POSITION) and the machine is being pushed, the pump is circulating the
liquid through the system. This circulation provides agitation and helps keep the liquids in suspension while walking the sprayer to and
from the area being treated.
