TUMBLER HITTING BLADES OR VACUUM BAR
The tumbler hitting the blades or baffle is often caused by one of the following:
•
the tumbler/baffle has been damaged.
•
the tumbler rollers are damaged and/or set too low.
•
the bed knife has been set too high.
If the tumbler is hitting the blades or vacuum bar:
1. Check the blades and vacuum bar for damage. If the damage is consistent
around the tumbler, it is likely the result of improper roller or blade height.
CHECK THE BED KNIFE AND HELIX BLADES FOR
CORRESPONDING WEAR
.
2. If the tumbler slot walls or vacuum bar seem to be damaged and bent out
of shape, you can try to bend them back to shape.
IF THEY CAN’T BE BENT BACK INTO SHAPE, ARRANGE FOR SERVICE AND
INSTALL REPLACEMENT PARTS.
3. Check the height of the tumbler rollers:
a) Roll the tumbler by hand and listen for contact. If the contact is
isolated to a single or a couple locations, it is likely caused by
damage to the tumbler. If it is consistent around the perimeter, is it
likely caused by misaligned rollers or blades.
HAVE THE
SERVICE TEAM RE-ADJUST THE ROLLERS AND/OR BLADES.
TRIM QUALITY IS LOW
If trim quality seems low on the T-ZERO:
1. Ensure all the steps in Powering the T-ZERO (see Operator Manual)
procedure have been completed.
2. Ensure all four helix blades are spinning.
a) If motor is on but blades are not spinning, verify that the belts are
intact and that the blade couplings have been installed
b) If frayed stems and leaf are exiting the tumbler, shut down the
machine and perform a paper cut test (see Adjusting the Blade
Contact on page 58).
3. Ensure the T-ZERO is off and make sure tumbler is filled approximately ⅓
full.
4. Ensure the feed conveyor is evenly feeding the T-ZERO.
Note: Fluctuations in tumbler volume often cause inconsistent flow inside the T-ZERO and
low trim quality.
5. Check if the tumbler is full:
