Filling Of Clean Water Tank; Adjustment Of Evc Operating Unit - Hardi Ranger 550 Instruction Book

Filling of clean water tank

A clean water tank is integrated into the front left corner of the main
tank (behind the MANIFOLD system). It is accessed for filling at the
sprayer's left side when entering the platform. Remove tank lid, fill with
clean water and replace tank lid.
For use of water, turn the ball valve lever to open tap. The ball valve is
located at the bottom of the clean water tank on sprayer's left side. The
water from this tank is for hand washing, cleaning of clogged nozzles,
etc. Only fill the clean water tank with clean water.
Capacity: 4.8 gal. (18 liters).
±
WARNING! Although the clean water tank is only filled with clean water, this water must never be used for drinking.

Adjustment of EVC operating unit

Before spraying, adjust the EVC operating unit using clean water
(without chemicals).
1. Choose the correct nozzle for the spray job. Make sure that all
nozzles are the same type and capacity. See the "Spray Technique"
book.
2. Make sure all distribution valves (A) are turned on.
3. Set pressure regulation valve to minimum pressure (activate
pressure regulation switch "down" until emergency handle stops
rotating).
4. Put the tractor in neutral and engage the pump. For belt driven
pump, adjust the P.T.O. revolutions to the number of revolutions that will typically be used while spraying. Remember
the number of revolutions on the P.T.O. must be kept between 300-600 r.p.m. (540 r.p.m. pump) or 650-1100 rpm (1000
r.p.m. pump). For hydraulic pump, see Ace Instruction manual for proper oil flow pressure.
5. Activate pressure regulation switch "up" until the required spraying pressure is shown on the pressure gauge.
Adjustment of pressure equalization:
1. Disconnect power to the control box to allow for manual operation of the boom distribution valves. Adjustments will
be made one section at a time until all valves have been adjusted.
2. Note the pressure on the pressure gauge. This reading will be used throughout the adjustment.
3. Manually close one of the distribution valves by turning the green handle (A).
4. Turn the adjusting screw (B), under the valve just closed, until the pressure gauge again shows the same pressure as
before (clockwise for higher pressure, counterclockwise for lower pressure).
5. Turn the distribution valve (A) back on.
6. Adjust the other sections of the distribution valve in the same way.
ATTENTION! HEREAFTER ADJUSTMENT OF PRESSURE EQUALIZATION WILL ONLY BE NEEDED WHEN:
1. YOU CHANGE TO NOZZLES WITH OTHER CAPACITIES
2. THE NOZZLE OUTPUT INCREASES AS THE NOZZLES WEAR
