Nugsmasher XP

INTRODUCTION

Thank you for the purchase of your NugSmasher® XP. We have designed this unit for the purpose of effortless rosin extraction for up to 28 grams of flower. When setting up your unit, please ensure your stand is suitable for the weight of the machine. Also note, that the unit gets hot and the high temperature hydraulic heat plates are capable of bodily injury if not used in a safe manner. (Please do not attempt to open your unit casing as this will void your factory warranty.)

While our products are sturdy and built to last, they are also heavy and shippers can be rough during handling. If there are any problems from shipping and your item does not deliver safely please contact us direct so we can resolve the matter immediately.

As always, please feel free to call us at any point with any questions or concerns at 951-272-9800 or NugSmasher®.com/contact.

QUICK START GUIDE

When starting your unit make sure the plates are closed (surface of plates should be pressed together) this will allow the temperature sensor in the bottom plate to get an accurate top and bottom reading and distribute the desired temperature to both plates. Additionally, bring plates together if more than 3 minutes passes to ensure accurate temperature readings. It is best to leave the plates together any time the machine is on and not in use.

KEEP RELEASE VALVE IN CLOSED “CLOCKWISE POSITION” WHEN NOT IN USE

Please note that under any circumstances do not turn release valve more then ½ a turn in the open (counter clockwise) direction as this will void your warranty and may result in hydraulic fluid loss. Also make sure when not in use or stored, the release valve must be in closed tight (clockwise) position.

WARNING!

Never turn your release knob more than ½ full turn counter clock wise from tight.

PLEASE NOTE:

Your release knob is factory designed to be a slight upward.

Set power switch to the “on” position. You will notice on your control screen there are two rows of digits. The top is the current temperature of the heat plates. The bottom is the set temperature. The XP comes preset at 200 degrees Fahrenheit and will take approximately 7-10 minutes to reach set temperature depending on your location.

ADJUSTING TEMPERATURE

Press the up or down arrows (red circle) to select desired temperature setting. Once you have changed to your desired temperature press the enter button (green circle) once to lock in temperature. It is not advised to go into any other programming modes as your unit has been factory preset for optimum settings. Note: US models are set for Fahrenheit and all international orders are set in Celsius unless specified otherwise.

UNIT OPERATION

Before your unit is turned on, insert handle into the vertical opening on the right side of unit. Notice there is a round tube that your shaft handle will be inserted into for plate compression operation. Pump handle until plates are lightly pressed together.

IDEAL TEMPERATURE:

The ideal pressure and temperature will vary depending on strain and growing techniques so don’t be discouraged on your results when you press new material. We recommend when pressing a new strain to start at approx. 220 degrees for flower and notate your yield results (weight of material in vs. rosin out). Perform additional test presses and drop 7 degrees per press until you notice your yield percentage starting to drop. Adjust back to the previous temp and that will be your ideal temp for that strain. It is advised to have a thermal temp gun to verify and check temperatures from time to time. Use our temperature test strips included with your unit (also available for purchase at NugSmasher®.com), unless in a pinch use a small piece of electrical tape as the high gloss on heat plates will affect accurate temp readings if using a thermal temp gun. (As shown in Illustration. The NugSmasher® XP has 2 heating elements in each plate and between presses of more than 3 minutes and especially during initial warm-up, it is advised to bring the plates back together to ensure exact set temperature is maintained in both plates.

PRESSURE:

Once your unit reaches set temperature you’re ready to start pressing. Once you have your material between parchment paper –do not use wax paper!-, slowly start raising plates by pumping handle. It is key to do this slowly to properly build heat into your material. The entire pressing process should be between 90-120 seconds depending on your strain. Note: Near the 60 second mark there may be a slight drop in pressure and may require additional pressure to be added to hold at desired pressure. There are several videos available online on the NugSmasher® social Instagram account as well as the NugSmasher® YouTube channel that are very beneficial for techniques and tips of your rosin extraction. Note the leverage designed with your pump handle is only designed for hand operation. Do not use any other leverage device or foot to push handle down as you will cause damage not covered by warranty. Visit Terp Files at nugsmasher.com/view-public-rosin-data/ for great reference to strains, temps and unit settings used.

LOADING MICRON BAGS:

NugSmasher® extraction bags, are recommended for optimal yield and clean quality rosin. Our bags are hand-made and packaged in the USA! NugSmasher® extraction bags are specially designed to work with the weight of fresh cured flower and are labeled accordingly at: 3.5 g (1.1g-3.5g), 7 g (3.6g-7g) and 14 g (7.1g-14g). This assumes the bags are loaded (BTS) or bottle/barrel-tech style (upright so that you end up with the round coin like puck once fully pressed). This perfected method allows you the ability to put the proper weight of flower into the bag and get a consistent extraction every time. This method also applies the proper pounds per square inch of pressure (PSI) on your product and eliminates the guess work.

NUGSMASHER NS-XP Rosin Press Machine - d2

3.5g bag (1.1g-3.5g) = 1.5″-1.6″ Diameter
7g bag (3.6g-7g) = 2″-2.2″ Diameter
14g bag (7.1g-14g) =2.4″-2.7″ Diameter

REMEMBER
“FIRE IN FIRE OUT!”

NUGSMASHER NS-XP Rosin Press Machine - d3

As the micron gets smaller the diameter gets larger, this is the reason for the variance in the diameter numbers above. We prefer to use 160 micron for fresh flower, as flower dries we go down in micron screen size (for dry flower use 90 micron). Micron size determines the diameter (surface area) of the smashed bag. For nugs 1g and smaller no bag is necessary.

Surface Area Key

NugSmasher® extraction bags, our bags are recommended or optimal yield and clean quality rosin. NugSmasher® extraction bags are specifically designed to work with the weight of fresh cured flower together with our extraction machines and are labeled accordingly at: 3.5g, 7g and 14g this assumes the bags are loaded (BTS) or bottle/barrel-tech style (upright so that you end up with the round coin like puck once fully pressed).

This perfected method allows you the ability to put the proper eight of flower into the bag and get a consistent extraction very time. The reason for this is that it allows for the proper pounds per square inch, pressure (PSI) on your product and eliminates the guess work.

3.5g = 1.5″ Diameter = 1.77″ in surface area
7g = 2″-2.2″ Diameter= 3.14″ in surface area
14g=2.4″-2.7″ Diameter= 4.91″ in surface area.

We prefer to use 160 micron for fresh flower, as flower dries we go down in micron screen size (for dry flower use 90 micron).

NOTE: As the micron gets smaller the diameter get slightly larger.
Example: 90 micron is about 5% larger at the end of your extraction.

EXTRACTION EXAMPLE:

One 3.5g bag

Plate Pressure
750 PSI

There is only one 3.5g bag that has the total surface area of around 1.77in².

Gauge Pressure
577 PSI

To extract your material at 750 PSI with a surface area of 1.77in (one 3.5g bag) it would equal 577 PSI on your gauge.

Two 3.5g bags

Plate Pressure
750 PSI

There are two 3.5g bags that has a total combined surface area of around 3.54in².

Gauge Pressure
1154 PSI

To extract your material at 750 PSI with a surface area of 3.54in² (1.77in² for each 3.5g bag) you would need 1154 PSI on your gauge.

SAFETY

Keep away from children, pets and clothing.
Never leave the extractor on when you go to sleep or leave the area.
Never use or store flammable liquids (such as gasoline) around the extractor. The flammable vapors can flow from one part of the room to another and be ignited by an electrical spark.
Place at least three feet away from objects such as bedding, furniture and drapes. Do not place where towels or other objects could fall on the extractor and start a fire.
Use extractor on the floor or bench top. Never place on furniture, since unit may fall , which could result in a fire or shock hazard. Do not use in wet or moist places, such as bathrooms; corrosion or other damage to parts in the unit may lead to a fire or shock hazard.
Do not hide cords under rugs or carpets. Placing anything on top of the cord or unit as it could cause the cord or machine to overheat, and can cause a fire.
Do not use an extension cord unless absolutely necessary. Using a light-duty, household extension cord with high-wattage appliances can start a fire. If you must use an extension cord, it must be marked #14 or #12 AWG; this tells the thickness or gauge of the wire in the cord. Do not use a cord marked #16 or #18 AWG. Only use extension cords bearing the label of an independent testing laboratory such a U.L. or E.T.L.
Be sure the plug fits snugly in the outlet. Since a loose plug can overheat, have a qualified repairman replace the worn-out plug or outlet. Since extractor draw lots of power, the cord and plug may feel warm. If the plug feels hot, unplug the heater and have a qualified repairman check for problems. Using an extractor with a hot cord or plug could start a fire.
If a extractor is used on an outlet protected by a ground fault circuit interrupter (GFCI) and the GFCI trips, do not assume the GFCI is broken. Because GFCls protect the location where leakage currents can cause a severe shock, stop using the extractor and have it checked, even it if seems to be working properly.
Broken extractor should be checked and repaired by a qualified service center. Do not attempt to repair, adjust or replace parts yourself as this will void warranty.
