How to Begin Extracting:

- Move the hydraulic heat press to the working area. 
Tip: Be sure to protect your working area from scratches during operation.
- Plug in power to the temperature control box. Turn on both platen power sub-switches and main power.
- Set the desired temperature on the temperature control box. our recommendation of 160-200F for fine material, 180-220F for flower.
Tip: Lower temperatures give a more flavorful extraction while higher temperatures give more returns.
- Close the release valve, which is centered on the bottom of the bottle jack, using the notched end of the - jack handle. Turn it clockwise until it’s closed.
- Insert the jack handle into the socket.
- Prepare your material either by hand or with your puck maker.
- Insert parchment paper in-between open plates, then insert your puck.
- Depress the jack handle down and up slowly (finer material such as sift, must apply pressure at a much slower speed to prevent your filter from blowouts) Continue to slowly apply pressure until either the color darkens considerably or you feel it is already tight. The pressure will ease off as the oil flows out, at this time we want to bring the pressure back to where it was. 
Tip: Using only enough pressure will give a higher quality extraction as to not introduce non-essential oils. If the parchment paper tears or is stained through to the other side, it is a good indication of excessive pressure. Try and aim for a tight feeling on the puck but not so tight that you have to put a lot of effort into your handle.
- Start a timer for 90 seconds with a smartphone. Check for additional flow during this time, and determine when to end your pressing time. 
Tip: Extraction times will vary, so it's important to let the flow of your extraction be your guide. Higher temperatures extractions will finish faster than lower temperatures.
- Remove the jack handle from the socket and open the release valve by turning it counterclockwise ½ turn.
Tip: If you are unable to open the release valve initially, use a pair of pliers or a wrench to loosen it.
- Remove parchment paper and puck carefully from the open platens.
- Collect your material, a cold plate from the freezer may help in your collection.
- Place honey in a storage container.
- Power off the Temperature Control Box if your pressing time is over.

         * Repeat steps 3-13 to continue working. 

Important Notices!

- Heated press platens are designed for pressing soft materials such as flowers and sift. Do not press hard objects between the heated plates or they will be damaged!
Collect your extractions on a cold surface and preserve them in your storage container as soon as possible.
- Power off the temperature control box if your pressing time is over. Excessive heat on the hydraulic system will decrease the working life of the seals and may cause premature failure.
Keep hands out from between heated platens once pressure is applied to prevent serious injury to yourself and others.

Questions & Answers:

Question: Could I replace the original bottle jack model with higher tons?
Answer: No, it is recommended that you use the same tons of bottle jack as your replacement. 

Question: Could I add a pressure gauge to the unit?
Answer: No, the bottle jack does not support a pressure gauge. 

Question: What humidity level should my flower be stored in?
Answer: 62% is the recommended stable relative humidity (RH) inside of your flower container. 

Question: How to measure the humidity in my flower container?
Answer: A small hygrometer will give you the humidity levels inside the container. 

Question: Can I re-press my pucks?
Answer: Yes!  Simply fold the puck in half and re-press it.  You might have to use a higher temperature to get an extraction. 

Question: Do I need to use filter bags for flowers?
Answer: No, you can press single flowers and get great results.

Question: How to test whether the jack holds pressure?
Answer: Please keep the minimum pressure more than 1 ton, then wait and see what happened between the dual heated platens.

Question: The jack can be pressed all the way down, why?
Answer: The jack will exhaust once it exceeds its rated pressure for safe working. Actually, the jack allows adjusting the pressure after taking off the red cap and rotating 45 degrees clockwise.


1 - How to fix uneven feet for my rosin press?

Please loosen the nut on the feet of the rosin press.
Keep the rosin press standing on the working table.
Screw in the nuts and tighten it.

2 - How to avoid the filter bags from blowing out?

Remove excess stems from flowers.
Use less material in your filter bag.
Preheating your material first to get it melty before you begin to apply pressure.
Apply the pressure more slowly.

3 - One of the heated platens doesn’t heat up.
Check the power sub-switch on the rear of the Temperature Control Box for the affected platen.

5 - How to apply the pressure for optimal yield and quality?

- Flower is the easiest material to extract. Slowly compress the puck until the oil begins to flow. As the extraction is flowing, it is important to keep some weight of downward force on the jack handle to maintain the level of pressure in which the oil is released. By applying too much pressure we may experience blowouts, or even introduce plant matter into our essential oils. Once the puck is mostly extracted you should no longer feel any more release of pressure on the jack handle.
- Sift and fine material will take some practice, so we advise you to preheat your puck between closed platens. They need to only touch the top and bottom of the puck for preheating. No pressure is required. Allow the puck to preheat for 20-30 seconds. At this time the puck should be melty and more likely to flow out instead of building up pressure inside which may cause a blowout. Gently apply pressure onto the puck and give it time to release the oil, slowly applying the pressure throughout the entire extraction. 

6 - The yields are not very good.

- If pressing Flower, verify your sealed storage jar’s humidity level is between 60-65%
Try a different variety.
- Sifting or hashing it first will allow you to press out a product with acceptable yields.
Pressing using the “bottle tech” method (squeezing cylinder vertical puck) can improve your yield
