Shut-down
1.
Release the trigger lever fully and screw in the safety button (back bushing item 18)
until it stops.
2.
Turn off material supply to the pump.
3.
Place the trigger guard Item 10 firmly to a grounded metal pail, turn on the
safety button and pull the trigger lever to relieve the pressure.
4.
Open the pressure relief valve (on site) on the pump to increase the pressure
from the pump, the valve and out of the hoses. The pressure relief valve
should remain open until work resumes. Triggering the gun may not be
sufficient to relieve the pressure. Keep a container handy to collect any
leaking material.
Warn
i
ng
The entire extrusion line must be always depressurized after work. The
pressurized pipes can burst and injure persons close by the outflowing material.
5.3
Setting the Material Flow Rate
The setting of the material flow rate - and thus the spray jet width - shall be
initially based on the selection of a suitable nozzle size. Setting the material
pressure regulator on the material and on the safety button of the back bushing
(Item 18) may also be affect the flow rate.
5.4
Regulating Material Pressure
The suitable material pressure you place on the pump (air pressure regulator on
site) and the material pressure regulator. Pay attention to the instructions and
safety of the manufacturer.

Operation
Safety
Observe the operation of the extrusion gun in accordance with the follow-the safety
instructions!
•
When work is interrupted, the extrusion system must be depressurized.
•
Wear proper respiratory protection and work clothes when you extrude the
extrusion gun materials. Airborne particles hazardous to your health.
•
In the workspace, Fire, naked flame and smoking is prohibited. Spraying of highly
flammable materials (eg glue) there is an increased risk of explosion and fire.
5.2
Start-up and Shut-down
Notice
Before first using the extrusion gun, flush it out with solvent to ensure that it is
clean.
Warn
i
ng
Turn power off before refitting the extrusion pressure from the system and check
the gauge, otherwise there is a risk of injury.
Before you can set the extrusion gun in operation, the fluid pressure must be
available at the extrusion gun.
Caution
The material pressure must not be set higher than:
- 350 bar
Start-up
1.
Before first use, the trigger lock is locked by screwing in the safety button until it
stops at the back bushing Item 18.
2.
Set the pump to minimum speed required to extrude the material with a
satisfactory discharge rate.
3.
Slowly unscrew the safety button (back bushing Item 18) and press the trigger
Item 8 to achieve the desired discharge rate. If there is not enough speed, then
the appropriate discharge rate can be further tuned alternating between safety
button and pump (on site air pressure regulator).
4.
If the settings are correct, you can start with the extrusion process.
