Work at a reasonable pace, thus avoiding constant stopping and restarting of the hydraulic assemblage. This machine is not designed
to withstand permanent, uninterrupted use at high pressure, but rather to run intermittently with pauses to allow for the dissipation of
the heat generated, the amount of which depends on the consistency of the mixture. Because of the pressure transmitted by the pump,
after prolonged periods of use the hydraulic oil may reach temperatures of up to 60ºC (140ºF) and the base side panel may bec ome
warm to the touch.
7. CLEANING
IMPORTANT:
In order to avoid mechanical hazards during cleaning operations and piston dismantling, always open the lid completely
when raising the piston.
7.1 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 sho uld 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.) an d 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:
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.
7.2 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 m echanical
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 barrel and screw the
piston-locking bolt tight, making sure that the smaller gasket is properly placed. Raise and lower the piston, and tighten the piston
locking bolt again, making sure it does not bend against the pressure of the lid. Grease the thread of the piston-locking bolt before
replacing it; this will make future dismantling easier.
When the machine is not in use, leave the piston head at the bottom of cylinder, where it will be submerged in hydraulic oil. This will
lengthen the life of the ram and the gaskets.

7.3 CLEANING CHECKLIST
IMPORTANT:
Never use a jet of water to clean any part of this machine!. When using detergents, disinfectants or maintenance oils,
follow the manufacturers‟ special instructions.
We recommend the use of cleaning or disinfecting products mentioned herewith. To clean the machine manually, always use
appropriate safety equipment (latex gloves, plastic aprons, etc.). Always rinse the machine thoroughly after using any kind of detergent
of disinfectant. Always follow the instruction provided by the manufacturer of the product.
