PULLEYS ALIGNMENT AND STRIPS TENSION
IMPORTANT: The strips must have some
tension so that the PTO’s power transmission
is adequate.
The pulleys must be aligned one with respect to the
other, otherwise the can pull outside, besides its
useful life reduces.
To verify that the pulleys are aligned, loosen the
screws and remove the guard, use a square or rule
(E) with enough length to support it simultaneously
on the pulleys flat faces, ensure if they are aligned
correctly. If necessary loosen the oppressors (B)
and move the pulley until it’s aligned with respect
to the other. Once they are aligned, tighten the
oppressors again.
Once you have aligned the strips and pulleys, you
have to tighten the strips. To perform this process
loosen the bearing screws (D), push it down and
tighten them once again, then loosen the bearing
screws (F) and turn the oppressor (C) clockwise
until the arrow is aligned with the top of the drawer.
then tighten the bearing screws (F) and verify if
the tension is adequate (0.256 in deflection), place
the guard back and if the tension is not adequate,
repeat the process once again.
Tighten the strips until the tier section deflection is
at 0.256 in. To verify the previous, press with one of
your thumbs, on the middle of the tier section and
measure with a rule the deflection. If the resulting
value is less than 0.256 in, loosen the strips a little
bit and if the higher, then tighten the strips.
ATTENTION: DO NOT align the pulleys
loosening the bearing oppressors and moving
the pulley drive arrow since this may damage
the arrow shaft operating angle.
