Magnum Venus Plastech Impregnator Roll - Manual (Page 25)

16. Stop Operation; re-assemble the nozzle and turbulent mixer, re-assemble the pour tube
assembly with the gun head and turn into place on machine. The Impregnator is now ready to
resume operation.
NOTE: When re-assembling parts noted in Step 16, all threads and “O” rings seals should be
well lubricated. See lubrication materials list.
If Impregnator unit is to be down for an extended period (2 hours or more) perform the following
procedure between steps 11 and 12.
a. Remove the bottom gun plug from the resin side (side plug if high volume unit). Hold hand over
the mix chamber of the gun and flush solvent through the plug port. Clean plug thoroughly.
b. Remove the side gun head plug from the catalyst side and blot out any excess catalyst from the
open port with clean cloth. Wash plug with clean water and replace.
CAUTION: All parts that contact raw catalyst should be cleaned with clean water only and
thoroughly dried before returning to service.
c. Turn air valve to power head of resin pump to off position.
d. Turn air valve to solvent pressure pot to off position and open relief valve on pressure pot.
e. Turn air regulator supplying air to gun trigger air valve to off position. Turn counter clockwise
until gauge reads zero.
The above steps “a” through “e” are safety precautions to prevent operation of material dispensing
system accidentally.
EXTENDED SHUT DOWN OR STORAGE
Should you wish to shut unit down for a prolonged period, 30 days or more, (15 days or more in
the case of the resin pump), the following procedure should be followed to insure all systems
will be operational when you wish to reactivate Impregnator.
1. All pressure should be bled from the pumping system.
2. The resin pump should have solvent cycled through until all trace of resin, etc., is removed. The
solvent should then be drained from pump, gun and hoses, and a light-weight oil cycled through
the pump only and then drained out.
3. Water should be cycled through catalyst pump, gun and hose until all trace of catalyst is
removed. Water should then be drained form pump and gun and they should be blown with
clean, dry air.
4. Clean gun head to remove all traces of resin and catalyst; inside and out.
5. Coat all exposed pump shafts and needle shafts with lubricant to protect from shop dust etc.
NOTE: Use no oils or lubricants on catalyst pump.
6. Lubricate all bearings, shafts, and working surfaces, such as roving mandrels, with lubriplate.
