Upon request, we will provide you with a list of active ingredients used in the spraying device. Make certain to read the instructions for use before using the device! Keep the instructions for use in a safe place where they can be easily found. Particular safety measures are required when working with the device. Improper use may result in dangerous injuries and environmental damage. 7393400_0618_ RS12_-RS18_16spr.indd 14 08.06.2018 11:04:5414 15 Only trained, healthy and rested people may work with the device. You should not be under the inuence of alcohol, drugs or medication. Child- ren and adolescents must not use the device. Keep the spraying devices out of the reach of children. Keep bystanders away during spraying. Take precautions to prevent hazar- dous substances from being misused. Wear suitable protective clothing, goggles and respiratory protection when working with hazardous substances. Never spray on people, animals, electrical devices and lines, into the wind, or into bodies of water. Avoid ignition sources in the environment. Do not leave the device in the sun. Ensure that the device is not heated beyond the maximum operating temperature (→ Table 1). Protect the device from frost and ammonia. Never blow through the nozzles or valves with your mouth. There is a risk of slipping or tripping on smooth or wet surfaces, snow, ice, on slopes and on uneven terrain. Repairs and modications to the tank are not permitted. Use only MESTO spare parts and accessories. We cannot assume any liability resulting from the use of third-party parts. When pumping, always observe the pressure gauge to ensure that the re- commended spraying pressure is maintained (→ Table 1 below). After use and before maintenance work, depressurize the device. Transport the devices in such a way that they are protected against damage and overturning.

1. Are tank [2], hose [6], shut-o󰀨 valve [8] with pressure gauge [22] and spray wand [7]

with nozzle [41] undamaged?

Pay special attention to the connections between the tank [17] – hose [6] and the hose [6] – shut-o valve [8] and to the condition of the spray wand [7]. Function:

2. Activate the pump lever [11]. (Fig. 8)

► Increasing pressure is indicated on the pressure gauge [22]. (Figs. 8 and 9)

1. Fasten the carrying strap [1] to the tank. Secure it with the metal pin [12]. (Fig. 2)

2. Attach the eyes [13] on the carrying strap [1] to both sides of the tank.

3. Attach the back cushion [9] to the tank using 2 bolts (outside) and 2 nuts with washers

(inside) [2]. (Figs. 2 and 3)

4. Press the 2 nuts [14] into the carrying handle [3] (for 18 liter devices only). Insert the

carrying handle and screw tight with the 2 screws [15] in the tank [2]. (Fig. 3)

5. Feed the hose [6] through the opening in the lower part of the tank as well as between

the shaft [16] and tank base. Push the hose all the way onto the connecting piece [17]. Tighten the union nut to secure the hose. (Fig. 4)

6. Push the hose [6] all the way onto the connecting piece of the shut-o󰀨 valve [8]. Tighten

the union nut to secure the hose. (Fig. 4)

7. Screw the spray wand [7] onto the shut-o󰀨 valve [8]. (Fig. 4)

8. Turn the shaft [16] clockwise until it engages. Insert the pump lever [10] to the required

depth into the shaft [16] (3 positions). (Fig. 5)

Pump lever [10] with handle can be tted on the left or right.

9. Secure the pump lever [10] in the shaft using the retaining clip [18]. (Fig. 5)

10. Push the handle [11] to the required position (A, B, C) into the pump lever [10]. (Fig. 5)

Ensure that the handle is locked in place in the pump lever.

The wheel lock [23] can be used to lock and unlock the lever on the shut-o valve [8]. Locking the lever [23b] prevents unintentional spraying.

3. Unlock the wheel lock [23a] and activate the shut-o󰀨 valve [8]. (Fig. 9)

► The shut-o󰀨 valve must open and close. Technical data Checks GB IRL AUS USA NZ CDN IND 7393400_0618_ RS12_-RS18_16spr.indd 16 08.06.2018 11:04:5516 17 Preparation Spraying

1. Place the device on its back. (Fig. 8)

2. Using the pump lever [11], pump slowly and regularly to maintain a continuous spraying

pressure. (→ Table 2, Fig. 8)

Max. pressure should not exceed 6 bar. If the maximum pressure is exceeded, the pressure relief valve will actuate and release the excess pressure from the pressure vessel.

1. Screw the cover [19] o󰀨 the tank. (Fig. 6)

Measuring cups [20] are integrated in the cover [19] and can be used to prepare the spraying agent. Fill the tank 1/3 with water, pour in the spraying agent and then ll up with water.

2. Pour the spray liquid through the lling strainer [21] into the tank. (Fig. 7)

In the case of 18 liter devices the maximum lling quantity is reached as soon as the liquid level can be seen in the lling strainer.

3. Screw the cover [19] onto the tank. (Fig. 6)

3. Ensure that the optimum spraying pressure is set on the pressure gauge [22] (Figs. 8

To prevent dripping, hold the spray wand up when rst spraying and activate the shut-o valve until no more liquid mixed with air comes out of the nozzle. Observe the instructions in the section entitled “Safety”. Operate the device only while it is vertical or suspended upright and nearly vertical. Avoid allowing drops of spray to drift onto areas that are not being treated. Observe the instructions of the spray product manufacturer! Have damaged parts or parts that do not work properly repaired immediately by our customer service department or by service partners authorized by us. Observe the instructions in the section entitled „Safety“. The device must be in an upright position. If lling the tank from a water line, ensure that the line or a hose does not project into the tank.

If liquid mixed with air emerges from the nozzle, the tank is empty. Pump the device completely empty after each fth lling at the latest. 7393400_0618_ RS12_-RS18_16spr.indd 17 08.06.2018 11:04:5518 19 Care and maintenance After using the device 50 times or if the device malfunctions, at least once a year, preferably after the winter break:

4. Clean the nozzle [41] and the insert [40] under running water. If required use a brush.

1. Activate the shut-o󰀨 valve [8] until the spray line is depressurized.

2. Screw the cover [19] o󰀨 the tank. (Fig. 6)

3. Dilute the remaining quantity twice in a row with 1/2 liter of water each time and spray

the resulting liquid onto the treated area.

4. Wipe o󰀨 the device with a moist cloth.

5. For drying and storing the device, remove the cover and keep the device in a dry place

protected from sunlight and freezing temperatures. Observe the legal requirements of your country for accident prevention and check the device in regular intervals. Unless otherwise specied, we recommend that an expert carries out an external test every 2 years and an internal test every 5 years as well as a strength test every 10 years. GB IRL AUS USA NZ CDN IND Observe the instructions in the section entitled “Safety”. Never leave liquid in the device. Collect and dispose of the residual liquid according to all applicable laws, require- ments and regulations. Observe the instructions of the spray product manufacturer! Clean the protective equipment and yourself every time after usage. Observe the instructions in the section entitled “Safety”. 7393400_0618_ RS12_-RS18_16spr.indd 18 08.06.2018 11:04:5518 19 Maintaining the intake valve Maintaining the pressure valve Removing the shaft and pull rod Replacing the O-ring on the pump rod Disassembling the shut-o󰀨 valve
