CLEANING
IMPORTANT:
In order to avoid mechanical hazards during cleaning operations and piston dismantling, always
open the lid completely when raising the piston.
CLEANING INSTRUCTIONS
To clean the outside of the machine use hot water and a mild cleanser. Do not use any abrasive products,
especially those that could scratch warning stickers and labels. Never wet or dampen the electrical elements
of the machine (switches, cables, etc.). Never use a jet of water to clean any part of the machine, especially
the air holes on the side of the oil tank cap. At the end of each workday, the underside of the lid (the mixture
exit hole), as well as the nozzle(s) and the nozzle nut should be cleaned thoroughly. If necessary, clean the
inside of the nozzles with a round brush. Do not open or close the lid without the green gasket in place since
this could scratch the lid and clamp. Using hot water only, rinse the lid bolt and bearing to eliminate any residue
that could crystallize (salts, spices, etc.) and thus impede the proper functioning of the lid. The upper part of
the black piston gasket should also be cleaned daily, following these steps:
•
Open the lid completely and remove the green lid gasket.
•
Press the knee lever until the piston rises to its uppermost position. Part of the black piston gasket will now
be accessible via the upper part of the barrel. Clean it with a damp cloth.
We recommend that you periodically clean the piston and barrel interior thoroughly:
•
Loosen the screws on the upper lid (E models only), open the lid completely and remove the green lid
gasket.
•
Press the knee lever until the piston rises to its uppermost position.
•
With the piston at its highest position, simultaneously push the knee lever and, with the aid of the two pivots
of the wrench supplied, unscrew the piston-locking bolt (two turns) located in the center of the piston.
•
Screw the wrench completely into the piston hole. The piston will rise above the rim of the barrel.
•
Pull the wrench up to remove the piston from the barrel.
•
Unplug the machine.
•
Clean the inside of the cylinder. Make sure that the bottom of the cylinder is completely DRY to avoid the
formation of water droplets, which could eventually lead to the formation of rust on the upper part of the
base.
IMPORTANT:
Piston and barrel cleaning can also be done by dismantling the removable barrel (E models
only); however, to avoid mechanical hazards as well as damage to the piston gaskets, we advise removal of
the piston only.
CLEANING PRECAUTIONS
Because of the weight of the piston, use caution when moving it. Clean the piston and the black piston gaskets
(1 or 2, depending on the model). To avoid damaging the gaskets, never use sharp or pointed tools (knives,
screwdrivers) to remove them. To reduce the noise caused by the movement of the piston, grease the piston
gaskets with food fat or another USDA approved shortening before putting them back into the barrel. Never
introduce water inside the barrel since it could filter down to the base of the machine and affect the electrical
and mechanical components. The holes in the bottom of the barrel are vents for air only.
To reassemble the piston, make sure that the bottom of the barrel is completely dry, then place the piston in the
