To safely operate the T4, it must be aached to one of
two vacuums: the Trim Saver or Leaf Collector. Each
vacuum requires a di@erent procedure for iniঞal setup.
For a list of available vacuums, see Vacuums and Bypass
on page 74.
Trim Saver Setup
Step 1: Secure the Stand Placement
If using mulঞple T4s in tandem, it is recommended they be placed on Twister Rails. For a list of
available rails, see Rails and Adapters on page 73.
1. Set up the stand where it will operate:
• If using a single T4, simply place the stand where the T4 will operate (see
Recommended Placement on page 12).
• If using T4s in tandem:
i. Assemble the rails (see the
corresponding Twister
Rails manual).
ii. Set up the rails where the
T4s will operate (see
Recommended Placement
on page 12).
iii. Adjust the stands’ levelling
feet so the stands are at
their minimum height
(see Fig. 13).
iv. Place the stands side by
side on the rails.
DO NOT CONNECT THE TRIMMER
OR VACUUM TO POWER UNTIL
ALL INITIAL SETUP STEPS HAVE
BEEN COMPLETED.

Step 2: Attach the Vacuum Attachment Coupling
1. Pull out and rotate the adjustment bar
lock knobs so they are facing straight
down* (see Fig. 14). This is to prevent
them breaking when the T4 is rotated.
1. Carefully rotate the T4 onto its side so it
rests on the adjustment bar (see
Fig. 15).
2. Place a hose clamp over the top of the
vacuum aachment coupling (see Fig. 16).
*The adjustment bar lock knobs, if pulled out, can rotate
without loosening the knobs.
RECOMMENDED PLACEMENT
For best and safest operaঞon, place the T4 stand/rails:
• On level ground.
• Near an outlet.
• In a cool environment*
• With enough space to easily access the tumbler inlet and outlet.
• With enough space to set up the vacuum(s).
*It is highly recommended to operate the T4 in as cold of an environment as possible. Operaࢼ ng the T4
in colder environments will improve the machine’s performance and signi cantly reduce build up on the
machine.

INITIAL SETUP
TILT GUIDELINES
Increasing the incline of the T4 will decrease the ll level of the tumbler and increase
throughput. For opঞmal performance, the T4 should be 1/3 full of product at all ঞmes
during operaঞon. When trimming a new product, it is normal to adjust the incline mulঞple
ঞmes to opঞmize product throughput.
