TILT ANGLE
Start with casters at the infeed end of the line approximately 1” off the floor. After the
tumbler has been primed and the feed rate has been dialed in for trim quality, adjust the
tilt angle up or down to maintain the tumbler at 65% - 75% full.
FEED RATE
As the tilt angle is adjusted the feed rate will also need to be adjusted to maintain the 65% -
75% fill level in the tumbler. If the tilt angle is increased, the feed rate will also increase. If the
tilt angle is decreased, the feed rate will also decrease.
DRY TRIMMING: TANDEM M108S SET-UP
When dry trimming with a tandem Mobius line, try starting with the following parameters
and adjust as necessary to reach the desired trim quality:
VFDs
Blades – both machines: At full power (11)
Vacuum – both machines: At full power (11). If the structure of the material is very open,
light, and larfy, consider lowering the vacuum of both machines to allow for the buds to
move more freely through the tumblers (in the range of 5 – 9). Alternatively, a single
trimmer can be used for very delicate, underdeveloped batches of material.
Tumbler – both machines: Start in the range of 5 – 7 and adjust as necessary.
TUMBLER FILL
‘Priming’ the tumblers is critical for dry trimming. Priming the tumblers in tandem means
filling the first tumbler and approximately half of the second tumbler as rapidly as possible
to 65% - 75% full. Once the tumblers are 65% - 75% full, lower the conveyor speed or the
speed of the manual feed to maintain a consistent fill level in the tumblers over the two
machines.
Because it can be difficult to tell how full the tumblers are when they are spinning, observe
how much of the blades are covered by plant material. When the first tumbler is properly
filled, the two blades towards the front of the machine will be completely covered and most
of the back blade, save the 4 to 10 inches closest to the infeed, will also be covered. The fill
level of the second tumbler will taper off in a similar way at the outfeed.
