1.
Perform the Unit Shutdown Procedures, following the method indicated in the Machine
Service Manual.
2.
Close the manual valves of each product by turning them to the full clockwise position.
3.
To eliminate the pressure from the gun, pull the trigger
and project the gun until the projection fan starts to
reduce.
4.
Press the safety stop and turn it clockwise to set it to the
blocking position
5.
Disconnect the air supply from the gun.
6.
Remove the cap and lubricate the mixing chamber with
the grease gun supplied in the tool kit; this action will
prevent the cleaning air of the gun from reacting with the
ISOCYANATE product and avoiding crystallization which
may damage the chamber and cap.
NB.:
The use of injecting lubrication into the gun at the end of the day will avoid
maintenance time, as it will not be necessary to remove the chamber each day to clean it.
PRECAUTION:
:
To avoid possible contamination by the product remains deposited in
the components of the gun, do not exchange the Isocyanate parts with the Polyol parts.
The gun has the Isocyanate side identified with the letter A.
If the product hoses maintain the pressure, follow the Standstill Method
indicated in the Machine Service Manual.
To eliminate the pressure from the hoses with the gun removed, fit the
product input blocks in a suitable container, keep a reasonable distance
away and very carefully and very slowly open the manual valves. Under
pressure, the product will come out of the side of the blocks.
