Assembly
Risk of injury!
Please note that high-pressure guns should only be used in conjunction with a lance which is at least 75cm long
and which offers sufficient space for your other hand!
If the high-pressure system has been used with hot water, allow the equipment to cool down to below 45°C due
to the risk of scalding or burning before starting assembly and maintenance work!
Manual interference when the high-pressure generator is running can lead to serious accidents!
Switch the high-pressure generator off before carrying out assembly work on the high-pressure system.
Secure the high-pressure generator against being unintentionally switched on.
Turn the water supply off.
Ensure that system sections and lines to be opened are not under pressure.
Seal the screw connectors in accordance with your intended use with an appropriate sealant such as Teflon sealing tape or a liquid sealant
(see R+M Catalogue, Chapter 06, Adhesives and sealing materials).
When assembling the lance and hose, secure the gun on the hexagon to prevent it turning and tighten the connectors to 25Nm.
Connect the high-pressure hose from the high-pressure generator to the spray gun inlet.
Assemble suitable accessories provided onto the output side.
After maintenance and repair work, check that the safety latch works correctly.
UL requirements
Spray gun can be used with cleaning machine type 3
Check for correct length of lance, it should be 36in (914mm) for type 2 and 4 feet(1,22m) for type 3 machines
Lance length have to be according UL 1776 §55
Modification
No modifications of any kind are to be made to the spray gun!
Operation
Operate the spray gun only within the pressure, flow rate and temperature ranges indicated. Before starting work, check the values on the high-
pressure generator and adjust these if necessary. After you have read the safety instructions, the spray gun is remarkably easy to use:
Hold the spray unit firmly at the provided hand grip areas and make sure your footing is secure.
To activate the spray gun, flip in the safety latch.
Press the trigger lever to start spraying.
Release the trigger lever to close the valve in the spray gun. The spray gun remains under pressure.
To prevent the valve in the spray gun from inadvertently opening again, flip out the safety latch.
Do not leave the spray gun unattended when the high-pressure generator is switched on.
Swivel joints (optional): To ensure that the high-pressure hose does not twist, a swivel joint can be used to connect the high-pressure
hose and spray gun. By using a swivel joint, the gun can easily rotate in relation to the hose when depressurised. As the pressure
increases, the swivel joint becomes more difficult to rotate.
Transportation and storage
Please ensure that the spray gun is cleaned and protected from contamination during transportation and storage. Protect the spray gun against
frost. The effect of frost can damage the gun so badly that it no longer works perfectly.
Cleaning
Clean the device prior to longer periods of inactivity. To clean the gun exterior, use a lint-free cleaning cloth and do not use any
aggressive cleaning agents.
Actuate the gun briefly to release any residual pressure. The high-pressure washer must be switched off.
