***IMPORTANT NOTE***
When re-installing the rubber roll pressure springs,the
optimal measurement setting for the springs is 31/32”
If after meeting all of the afore mentioned sequential
troubleshooting criteria,a grinding noise persists,chances
are the drive motor gearbox has failed.As the gearbox is an
integral part of the drive motor itself(part # PRM220),the
drive motor should then be removed(see SECTION 3,A-3)
replaced,and rewired exactly as shown in the schematic.
The drive system should now be perfectly functional.
SECTION 4:TROUBLESHOOTING WEB TENSION
(wrinkling,waviness)
ROLL PRESSURE
(steering,
uncontrollable wrinkling),
AND ADHESION
(peeling,not
sticking)
PROBLEMS
1)
Basic.
The majority of web(film)tension or wrinkling
problems and adhesion problems are covered in the owners
manual.Please refer to section 5-8,Preventing and Solving
Problems,for answers to basic questions concerning
wrinkling and non-adhesion.
If,after consulting the owners manual,wrinkling problems
persist,visually examine the supply roll assembly(part #
0500-002.5 top and bottom).Check to see if the brass
supply roll dog located in the center of the supply roll is
missing or loose.If missing,replace it(part # 0285-015.4),call
your dealer or Ledco for the part.If its loose,using a phillips
head screwdriver,tighten the 6-32x3/16 round head screw
that secures the dog to the mandrel.If wrinkling persists,
visually check the hex adaptor(part # 0285-023.4)at the end
