Section 3: Installation
After unpacking and before running, it is important to check that fasteners did not become loose during shipping.
Check all nuts, bolts and screws to make sure everything is tight.
Check for proper voltage before connecting any power to the machine.
The voltage and amperage of the power supply depends on the specifications
provided by the customer. Information can be found on page 2 of this manual.
If you choose not to use the plug supplied with machine, run appropriate supply voltage through a strain relief in
the control box to the terminals labeled L1, L2 and L3, if three phase. Please refer to the electrical diagram in this
manual for the specific location.

Section 3: Installation
Each set of bags consists of 6 individual units containing 2 layers each. The units are secured to each other using
hook and loop Velcro. Each bag has grommets on the bottom corners and the end bags have grommets on the top in
place of the Velcro. The grommets on the end bags are spaced to easily slip over the bag pins on the press area. The
grommets on the bottom of the bags are used to secure the bottom of the bags during the dumping process.
Knot the bag loops through the bottom grommets. We recommend having the bag sets preassembled and bag loops
attached, before inserting them into the press.
Place one layer only, into each section of the scissor assembly (you may find it easier to begin at one end and work
your way to the other end).
After all the layers are properly placed, grasp the bag loops and pull them over the bag tab. Each bag corner is
attached with one bag loop which gets attached to two bag tabs as shown below.

Check to make sure all components are in place as described in the installation section.
Turn the disconnect switch to the “ON” position and pull the “E-Stop” button out to start the motor and pump.
Turn directional switch to the forward or reverse position until it stops (the motor and pump will continue to run). The
press does not need to be turned o when it is at full press stage, as there is a built-in override system which is designed to
maintain constant pressure without damaging the press.
Fill the open side of the press with slurry using a suitable pump. Do not fill one bag at a time, fill them uniformly.
Fill the bags 2’’ to 3” from the top.
Turn the switch to the forward or reverse position to press slurry. After pressing is complete allow the press to hold for
about 2 minutes longer to ensure full extraction.
The open side of the press is now ready to be filled. Repeat steps 3,4, and 5.
Turn the switch in the appropriate direction to begin squeezing the side just filled.
As the side previously pressed opens, gently work the cake separator between the bag and dry cake on both sides of the
cake on all layers.
Be careful not to wear bottoms and sides of the bags by jamming the cake separator into the layers. Re- member to always use
your cake separator to loosen the cakes in the bags before dumping! Caution should be used in order not to cut the seam on the
sides of the bags. Always be sure all edges of the cake separator are smooth, without nicks or sharp edges. Never force the cake
separator. Gently cutting the cakes in half will allow for an easier dump and increase the life of the bags.
When all cakes have been separated from the bag, press the “lift” button to raise and dump the dry cake from the bags.
When the bags are empty, flip the press area back over and repeat. The “lift” button must be released when the press area
reaches its pivot point in order to fall over.

Section 4: Operation
SAFETY GLASSES must be worn at all times during operation.
Beware of all pinch-points and moving parts.
Factory preset is set to full speed. You may find it necessary to adjust the speed to get maximum yield. Soft pom-
ace needs to be pressed at slower speeds. This allows the juice to be extracted without the pomace overflowing
the top of the bag. The speed is adjusted by using the two vernier speed control knobs. To slow down the pressing
cycle, simply turn the appropriate knob clockwise.


4.2 PRESS SPEED
IF PRESS IS TOO SLOW:
This will not have a negative eect on the juice or the machine but will decrease the amount of produce per hour the
machine can handle.
IF PRESS IS TOO FAST:
This generally causes undesired outcomes. 1.) The produce can slide up and out of the press bag. 2.) The pressure inside
the bag can climb too fast, possibly causing the bag to rupture or forcing produce to extrude through the bag. 3.) Juice
will squirt up and out of the press. 4.) Produce will have lower yields because there was not a slow gradual increase in
pressure.
IF PRESS SPEED IS JUST RIGHT:
The press should be set to a speed such that the platen slowly moves in and squeezes the produce while increasing
pressure slowly. Due to the diversity of produce, this machine is capable of processing the variety of characteristics
contained in various fruits and vegetables. Therefore, press speed should be adjusted to the customer’s specific needs.

The first step in cleaning is to disconnect any hand-removable parts and place them in a sink or set them aside for
cleaning and sanitizing, separately.
All remaining produce should be hosed o and removed. Avoid spraying water directly at motors and controls.
After all easily-removable debris has been cleaned o, we recommend using a foaming cleanser to help break down
remaining particles. “Masterklean” can be purchased through customer service, or another product similar to
Masterkleen may be used. For information on the chemical makeup of “Masterklean” please contact Goodnature
Products, customer service (716)-855-3325.
Mix up 3 gallons of cleanser solution, as described in the instructions enclosed with the cleanser, using hot water. Wash
down all surfaces taking care to thoroughly clean all areas that produce has come into contact with.
All removed parts can be washed and sanitized by hand in a sink or soaked if desired.

Turn bag inside out.
Rinse bag thoroughly in sink, or hose down. All loose particles should be rinsed out.
Soak bags in a tub filled with a caustic solution (a lightly chlorinated solution). Goodnature can supply cleanser if desired,
please contact customer service at 716-855-3325. Bags should be soaked for a minimum of 30 minutes up to 2 hours.
Place bags in a standard washing machine and add in a chlorine cleanser.
Run the machine with a cold wash, and a hot rinse (Ideally above 100F but below 140F). The temperature of the rinse is
important because this is required to remove residual chlorine.
When cycle is complete, hang bags to dry. Never let bags sit wet in a bucket or sink for an extended period of time.
If bags do not come out white, repeat operation from step 3.
Bags should be replaced after 6 months of daily operation.

Keep machine clean and free of any foreign objects.
Apply food-grade grease to the top and bottom of the rail on both sides of the press. This allows the shims to slide
with little resistance.
Check all fasteners for tightness and damage.
Inspect press racks for cracks or sharp edges.
Inspect hydraulic lines for damage of leaks.
Check hydraulic fluid level. With the press retracted or in the open position, remove the breather cap from the
hydraulic reservoir. Use a dipstick to check level of fluid, it should be about 1” below the hole. If it is low, add SAE 10
all purpose hydraulic fluid. If your system was designed for food grade or specialty fluid, use appropriate fluid.
Apply food-grade grease to the 3 grease fittings located on the scissor assembly hinges.
Inspect all nuts and bolts for proper tightness. Critical for proper operation of scissor assembly.
* Oil Filter– Replace oil filter after first 50 hours then every 250 hours thereafter (Part# 13867).

Press speed too fast or too slow—Adjust the speed according to section 4-2, speed of press.
Platen does not move—Turn flow control knob counter-clockwise and try to run the press back and forth. It is also
possible a fuse may have blown; have a qualified electrician check for electrical fault.
Platen moves erratically or jumps—This indicates oil level is low; check the hydraulic reservoir oil level. Be sure to check
this with the cylinders fully retracted.
Press moves too slow— This can indicate that flow control valve is too restricted or is plugged; Turn flow control knob
counter-clockwise to achieve one inch travel per 13 seconds.
Pomace squirts up when pressing—This could be caused from several factors; bags are too dirty or plugged— clean bags
or it may be time for a new set. Bags are too full—keep the bags 50-75% full. An improper grind—move to larger screen for
chunkier grind. Press speed— usually means it’s too fast. Warm overripe fruit—if possible, cool soft fruit before pressing.
It is often found that using a press-aid will remedy some of these problems.
