Note: perform these steps with the machine unplugged
Check tumbler condition. Ensure wires are not kinked or frayed. Ensure rings and end caps are flush and sealed. Ensure tumbler has been stored properly before use (i.e. that is has been stored in a plastic bag with water).
With lid open, install tumbler and pump air into piston with the pump lever up. When the air pressure reaches 130, flip the pump lever down and remove the pump. Wait 10 minutes. Reinstall pump with pump lever up. Gauge should read 120 psi (10 psi reduction is due to the air that is in the pump hose). Pump up to 140psi and remove pump.
Check trim tote gasket condition. Ensure gasket is not damaged and is securely attached to trim tote all the way around the rim.
Check trim tote condition. Trim tote should be rectangular (not bowed or distorted) and should not have any cracks or tears.
Check trim tote sensor cable to ensure it is in good condition. Wipe the sensor cable end and the body receptacle with an iso wipe to ensure there is no reside impeding the connection.
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). Ensure dowel pin is in place.
Check brush to ensure there is no damage to bristles.
Check E-box filter, located under the power receptacle. Change out if necessary
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 plastic bag with a few drops of water. This will maintain the flexibility of the tumbler rings and end caps.
Remove valve core from Schrader valve then remove piston from lid assembly.
Clean and inspect the piston chamber.
Remove o-rings from piston and clean the piston.
Lubricate and install new o-rings, ensuring that the 225mm o-ring is on the OD and the 215mm o-ring is on the ID.
Lubricate the sides of the piston chamber and install the piston, ensuring that that o-rings remain seated in their channels of the piston (i.e. that they are not pinched out when the piston is installed).
Install a new valve core stem.
Test the piston for air tightness by performing the following steps:
- With lid open, install tumbler and pump air into piston with the pump lever up.
- When the air pressure reaches 130, flip the pump lever down and remove the pump.
- Wait 10 minutes.
- Reinstall pump with pump lever up.
- Gauge should read 120 psi (10 psi reduction is due to the air that is in the pump hose).
Remove dust and other particulate that may have accumulated inside the E-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 ‘hockey stick’ to ensure that it is in good working condition and not bent.
Check trim tote engagement levers and rails to ensure that a proper seal is achieved when the trim tote is installed.
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.
Review inventory of tumblers, helical blades, bed knives, spacer bars, brushes, trim totes and trim tote gaskets, ensuring that an appropriate number of each part is on-hand and in good working condition.
Perform a visual inspection of the impeller to ensure that it is in good condition.
