Projection Gun novaG-M
Service Manual
When it stops projecting, always turn the safety device to the blocking position to avoid
any kind of accidental damage when handling the gun.
12. Check the air regulator. Turn it anti-clockwise for an airflow that cleans any remains of
product that might be at the tip of the PCD and on the needle. Excessive air will distort the
projection fan. To completely close the air, turn it clockwise.
13. Carry out a test projection in a vessel.
WARNING:
Before doing maintenance, repair or cleaning work, press the safety device
and turn it clockwise to leave it in blocking position, always remove the Coupling Block
from the gun, completely close the manual product input valves and disconnect the air
supply to avoid any possible accidents.
STOPPING METHOD
When stops are made of over 30 minutes, the non-return units of each product must be
checked and cleaned, as well as the filters, chamber and PCD. (See the Maintenance section
on page 17).
Perform the following steps to ensure correct operation:
1.
Perform the Unit Standstill Method with the procedure indicated in the Machine Service
Manual.
2.
Completely close the manual valves of each product by turning them clockwise.
3.
To eliminate the pressure from the gun, press the trigger and project with the gun until the
projection fan begins to narrow.
4.
Press the safety device and turn it clockwise to leave it in standstill or blocked position (see
Figure. 8, page 10).
5.
Remove the coupling block from the gun. Use a cloth dampened with solvent to clean the
contact surfaces and the seals of the coupling block.
6.
Remove the non-return unit and filter from the Polyol side on the mixing block. Clean the
unit with gun-cleaning solvent and also the block housing (see Figure. 19, page 18).
7.
Remove the non-return unit and filter from the Isocyanate side on the mixing block. Clean
the unit with gun-cleaning solvent and also the block housing (see Figure. 19, page 18).
8.
Remove the filters. Clean them carefully with gun-cleaning solvent, making sure that the
mesh is completely free of product remains. Clean and dry the housing well.
PRECAUTION:
To avoid spilling the rest of the product which has accumulated in the
side cartridges onto the floor, always remove the coupling block and the side cartridges
on a waste vessel.
