Check tumbler condition. Ensure wires are not kinked or frayed. Ensure rings are flush and sealed.

Check piston condition. With lid open, install tumbler and pump up to 120 psi. Leave pump attached to piston. After 10 minutes, check that pump gauge still reads 120 psi.

Check trim tote gasket condition. Ensure gasket is not damaged and is securely attached to trim tote.

Check trim tote sensor cable to ensure it is in good condition.

Check helical blades, bed knives and spacer bars to ensure there is no damage (i.e. no nicks on the cutting edges or gouges on the body of each of these parts).

Thoroughly clean all plant-touching parts and place parts in an orientation that ensures that they drain and dry completely.

Store clean tumblers in a room with relatively high humidity or seal in a plastic bag with a few drops of water. This will maintain the flexibility of the tumbler rings and end caps.

With lid open, install tumbler and pump up to 120 psi. Leave pump attached to piston. Wait 30 minutes and check that pump gauge still reads 120 psi.

Remove dust and other particulate that may have accumulated inside the electrical box of the machine. To access this area, remove the 6 screws from the site panel and use compressed air and a vacuum to remove the particulate.

Check condition of gears and pulleys on left side of machine, lid and all helical blades. Ensure there are no significant signs of wear.

Check belt tension, aiming for 10 KG tension.

Check o-rings on underside of lid to ensure they are in good condition.
