Safety Risk of explosion due to explosive substances Risk of accident due to electricity or electrostatic charge Risk of crushing due to lifting movements Risk of cutting injuries due to rotating machine parts Risk of burning due to hot surfaces Risk of freezing due to cold surfaces The first line of the safety instructions indicates the personal protective equipment that must be worn.
Safety 2.2 Safety notes Always remember that the machine operates in a high pressure process and can cause life-endangering injuries if handled incorrectly! Always observe and follow all information in this operation manual and in the separate operation manuals for the individual machine parts or the optionally available auxiliary devices.
➤ continuous contact with the container wall. Only use conductive material hoses. ➤ All original material hoses from WIWA are conductive and designed for our machines. WARNING If the machine becomes contaminated with coating material during spraying, a static charge may result due to the increasing coating thickness. Static discharges can result in fire and explosions.

Safety 2.4 Safety features WARNING If safety feature is missing or is not fully functional, the operating safety of the machine is not guaranteed! Put the machine out of operation immediately if you detect safety feature ➤ defects or any other faults on the machine. Only put the machine back into operation once the faults have been fully ➤...
Safety 2.4.1 Safety valve Safety valves are located on the machine: in the air motor for the proportioning pump ➤ in the air motor for the flush pump (if present) ➤ The safety valve prevents the maximum permissible air inlet pressure from being exceeded.
Safety 2.5 Operating and maintenance personnel 2.5.1 Obligations of the machine owner The machine owner: is responsible for training the operating and maintenance personnel, ➤ must instruct the operating and maintenance personnel on correct handling ➤ of the machine, and on wearing the correct work clothing and protective equipment, must make work aids, such as e.g.
When repairing and maintaining the machine, only original spare parts from ➤ WIWA may be used. If spare parts are used, that have not been produced or supplied by WIWA ➤ then the guarantee is voided and all liability shall be excluded.
Safety 2.7 How to respond in an emergency 2.7.1 Shutting down and de-pressurising the machine In an emergency, bring the machine to an immediate standstill and relieve the pressure. Close the compressed air shut-off valve. Actuate the one-hand lever on the mixing unit again briefly so that no material pressure is present and the machine is completely free of pressure.

Machine description 3.4 Compressed air connection The connection of the compressed air line provided by the owner occurs at the compressed air connection. The compressed air supply for the entire machine is opened or interrupted with the compressed air shut-off valve. Separate compressed air regulators are present for the proportioning pump and flush pump.
Machine description The functional principle of all compressed air regulators installed on the machine is the same: To increase the pressure, turn the adjusting screw ➤ clockwise, To decrease the pressure, turn the adjusting screw ➤ counter-clockwise. 3.5 Mixing unit The 2K GEL UNIT is optionally available with an external mixing unit.
Transport, installation, and assembly 4 Transport, installation, and assembly The machine left the factory in faultless condition, packaged correctly for transport.

Transport, installation, and assembly Safety measures at the installation site: For safe operation of the machine, stability and sufficient free space must ➤ be ensured. Keep the working area clean, especially all walking and standing areas. ➤ Remove any spilled material and cleaning agents immediately. In order to prevent harm to health and damage to property, ensure sufficient ➤...
Transport, installation, and assembly 4.3.1 Installing the material hose and mixing unit If the machine is delivered with WIWA material hoses and a WIWA mixing unit, observe and follow the information in this chapter. WARNING Parts that are not designed for the maximum permissible working pressure of the machine may rupture and cause serious injury.
Transport, installation, and assembly 4.3.2 Installing the flushing agent hose Depending on the machine type, the 2K GEL UNIT is equipped with a flushing agent pump. Connect the flushing agent hose marked yellow to the material outlet of the flush pump. Fig.
Operation 5 Operation Prerequisites: The machine must be correctly installed and fully assembled. ➤ Only put the machine into operation if you are equipped with the prescribed ➤ personal protective equipment. Details on this can be found in chap. 2.5.4 on page 13.
Operation Set the one-hand lever of the mixing unit to "Stop" and close the flushing ball valves on the mixing unit. Make sure that all compressed air regulators are turned down completely. Place the suction for the flush pump into the cleaning agent container. Point the outlet opening on the static mixer into an empty container to be able to collect the escaping material mixture.

Operation 5.4 Flushing Flushing is used to flush the mixed material out of the machine during an interruption to the spray operation before it hardens. Flush all parts that have come into contact with the mixed material within the pot life stipulated by the manufacturer. Hold the mixing unit, directing the material ejection against the inner wall of the collecting vessel.
Operation 5.7 Cleaning the machine completely A complete cleaning of the machine is necessary: during the initial commissioning so that the spraying material is not ➤ influenced by the test substance with which the machine was tested for correct operation in the factory. during a change of the material.
The machine has been specially configured for your application case. It is necessary to check compatibility of the materials used with other materials in each individual case. WIWA is happy to help determine the suitability of your machine for another material.
Maintenance and repair work on electrical parts may only be performed ➤ by specialist personnel with electrical qualifications — all other maintenance and repair work may only be performed by WIWA customer service or specially trained personnel. WARNING During maintenance work, ignition sources may develop (e.g. due to mechanical sparks, electrostatic discharge, etc.).
In this case, have the pump packing replaced as quickly as possible. After performing the check, add a corresponding quantity of clean release agent through the filler opening. We recommend using the release agent from WIWA (order no. 0163333). Original operation manual 2K GEL UNIT 2KGel_14025_25015_BAoDB_en_1701 • rs...
