Occurring problems

1. No material is flowing trough the pistol, the motor have stopped or is not running.

2. No B component material is flowing trough the pistol. Observed when controlling the machine at start.


 

1. Problem

No material is flowing trough the pistol, the motor have stopped.

Possible solutions

1. In most cases the stop depends on sledged hoses to the pistol, this is caused by A Component going in to the B component and curing taking place. 

Switch off the machine by closing the handle, then switch of the manoeuvre switch on the machine. Move the pistol handle forward, to release the pressure in the hoses. 

Unscrew the B component hose from the pistol carefully; the hose can still be at some pressure! 

After unscrewing the hose place it in a container and start the machine for a short moment. If B component is flowing through the hose, the stop is probably within the handle.

Unscrew all openings in the handle and control carefully visually as well as with a 5mm drill bit or a screwdriver. All openings MUST be clean, the handle can be dismounted, all pieces are put into solvent such as Methyl ethyl keton (MEK) for about 12 hours.

Ball valve  can be ordered as spare parts and can then be changed while the blocked parts are cleaned. In this way you can avoid long stops in the moulding process.

2. The magnetic sensor in the right hand side of the handle is not working meaning that the current to the motor is broken. Change the magnetic sensor.


 3. No B component material is flowing trough the pistol. Observed at the control in the starting of the machine. Solution The magnetic sensor in the left hand side is out of order. Change this magnetic sensor.
