PRECAUTION!
The unit includes components that reach temperature that are liable to
cause burns. The hot parts of the unit must not be handled until they have cooled.
When you plan to shut down the machine for more than FOUR weeks, the products contained
in the machine must be replaced by DOTP plasticizing agent.
Follow the recommended process in the order indicated, to change the products for DOTP oil:
a) Place two drums of DOTP cleaning agent close to the machine.
b) Dismantle the gun and leave the coupling block connected to the hoses.
c) Remove the transfer pumps of the product drums and place them in the drums of the
DOTP cleaning agent.
d) Place a vessel under the coupling block to gather up the products contained inside the
machine.
e) Open the manual valves on the coupling block and press the MOTOR and NORMAL
keys to start up the dosing pumps.
f) Allow the products to come out until you see that only DOTP cleaning agent comes out
free of impurities.
g) Deactivate the MOTOR and NORMAL keys, close the valves on the coupling block, turn
the general switch OFF, disconnect the supply system of the transfer pumps and the
process is finished. The metering pumps, the heaters and the hoses must be full of
DOTP plasticizing oil. Never leave the machine or the hoses empty of product or DOTP
plasticizing oil.
NOTE:
Never use liquids not recommended or not approved by HI-TECH. Never use
approved liquids that have been contaminated with water or ISO/POL. If you are not sure
in the quality of the liquid you are going to use we strongly recommend that you check
the machine 2-3 times every 2 weeks after you have filled it by recirculating through
heated hoses (see p.26) with fresh plasticizer unless you make sure the liquid that comes
out is completely pure and clean.
