Installation of the spray tube (6):

Correctly insert the seal (5) according to Fig. 1 and screw on the spray tube with the already- installed nozzle attachment (7) hand-tightly without using tools.

Checking for operationally safe condition

• Subject the pressure sprayer to a visual inspection before every use. There must be no cracks evident at the tank (1), the pump unit (4), the spray tube (6) and the nozzle attachment (7).

• The following inspections must be performed at first commissioning and at recommissioning after extended standstill. During use of the pressure sprayer, proper function generally must be verified in operation.

  • Tightness of all sprayer parts at maximum admissible pressure with the hand valve opened and closed
  • Function of all working parts (hand valve, pump, pressure relief valve)
    For this, build up pressure across the pump (Fig. 3). The pressure must escape with a clearly audible sound when you actuate the pressure relief valve (Fig. 4).

• The device always must be vertical when the pressure relief valve is actuated. Attention: Keep it away from your face!

• Check the function of the shut-off valve during application. When releasing the shut-off valve, spraying must stop.

• In case of irregularities, damage, leaks or limited function, do not use the sprayer but have it checked in a specialist workshop without delay.

Preparing the spray liquid and filling the spray tank

• Prepare the spray liquid according to the instructions of the chemical manufacturer. Before opening the spraying agent tank, the device must be depressurised by actuating the pressure relief valve (2) (Fig. 4)!
  Fig. 2:

• To fill the tank with spraying agent, the pump must be unscrewed. by turning it counterclockwise.

• Do not use any tools!

• Fill the tank no further than to the upper-most mark on the side of the spray tank.

• Overfilling the tank or spills can contaminate public waterways, rain- and storm water channel and must be avoided.

• Wipe off spilled spray liquid without delay.

• After filling, insert the pump again and refasten firmly by turning the pump handle (c) clockwise to prevent the spraying agent from escaping.

Using the pressure sprayer

Spraying
For pumping, pump up and down with the pump button (5) until the operating pressure is reached in the spraying agent tank (Fig. 3). Overpressure escapes on its own through the pressure-relief valve (2).
Always hold the pressure sprayer vertically for spraying.
Actuate the shut-off valve (3) (Fig. 5). The actuation lever of the shut-off valve can be pushed forward for permanent actuation (Fig. 6). To stop spraying, pull the actuation lever of the shut-off valve back again and release it.

Nozzle adjustment (Fig. 7):

• a) Nozzle closed
  → hollow cone

• b) Nozzle open (max. 1 turn, 360″)
  → coarse and narrow jet

Disposal of residual spray volume
Residual spray volumes of less than 10 ml [0.3 oz] are no longer pumped effectively.
If you do not want to fill in any more spraying agent and want to end spraying, collect and dispose of the remaining amount according to the applicable laws and provisions. Observe the information from the spraying agent manufacturer.
At the end of the work, empty and clean the sprayer according to chap. 9.2, wash face and hands thoroughly and take off the work clothing. Work clothing requires regular washing.

Maintenance, cleaning and storage

Greasing the cap gasket
If it is growing more difficult over time to screw the pump unit onto the tank tightly, silicone grease may be applied to the contact surface between the lid seal and the tank edge. For this, it is easiest to apply a little grease onto the tank edge with a brush. (Fig. 9)

Draining the spraying agent tank and cleaning the spraying agent carrying parts

• The device must be depressurised by actuating the pressure-relief valve (2) before opening the spraying agent tank and before disassembly of the nozzle attachment (Fig. 4)!

• empty the spraying agent tank after use every day.
  Collect and dispose of the residual quantity of the spraying agent according to the applicable law and provisions. Observe the information from the spraying medium manufacturer. Flush the spraying agent tank and all spraying- agent-conducting parts thoroughly with clean water. Operate the pressure sprayer once more with clear water.

• Let the spraying agent tank dry again in the open condition after cleaning.

• Clean the spraying nozzle as follows after every 50 uses, or if the spraying pattern grows uneven, or if much less spraying agent then before is dispensed:

  • Screw the nozzle attachment (7) off of the spray tube (6) and flush with clean water.
  • Disassemble the nozzle attachment (Fig. 1).
  • Clean the O-rings and the parts of the spraying nozzle with clean water and a soft brush (Fig. 8).

Do not blow out the spraying nozzle with your mouth!
Do not clean the nozzle with any hard objects!

  * Assemble the individual parts of the nozzle attachment again.

Down periods and storage
Empty and clean the sprayer according to chap.
Keep the sprayer protected from sunlight in a dry, frost-free and secure location at a temperature of max. 35 °C [95 °F].
No open fireplaces or similar must be nearby.
Prevent unauthorised use – especially by children.
