Remove the stopper and grease the mix
chamber with the greasing pump supplied in the
kit with the gun. this will prevent the cleaning air
of the gun from drying the ISOCYANATE
product, and will therefore prevent it from
crystallising and scratching the chamber and
the bushing.
NB.:
The action of lubricating 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 product remains on the gun
components, do not swap Isocyanate parts with Polyol parts. The gun has the Isocyanate
side marked with the letter A.
If the product hoses still have pressure, follow the Standstill Method
indicated in the Machine Service Manual.
To eliminate the pressure from the hoses with the gun dismantled, put the
product inlet coupling block in a suitable container, remain at a careful
distance and very carefully, very slowly open the manual valves. With
pressure, the product will come out of the top of the coupling block.
