INTRODUCTIONINTRODUCTION
The G Lite Tabletop Cannabis Grinder is utilized in your post-harvest processing of hemp and
cannabis. The G Lite destems and grinds, it is the first machine of its kind that gives users
complete control of their finished product with perfect consistency. The G’s low RPM grinding
preserves trichomes and separates stems from material simultaneously.
The G Lite is consists mainly of a grinding assembly. It includes speed controls which allow users
to customize the size of the grind, get a consistent mill, and speed up downstream processes.
The assembly comes with the 1/8” screen size. The other screen sizes -- 5/32” and 3/16”-- are
available for purchase. Functions can be manipulated and adapted further by utilizing the
machine’s angle control.
The G Lite’s surgical stainless-steel construction discourages microbial growth and makes it easy
for users to break down and pressure wash the entire unit, minimizing downtime. The machine
has the smallest footprint of any grinder in its class. It can easily be transported to wherever it’s
needed.

The SLOWER the grinding equates
to higher torque and increased stem
removal. Slower RPMs allow buds
more time to align with the face
of the blade, keeping them intact.
HOWEVER, there would be less
throughput.
The FASTER the grinder rotates, the
less torque it has, and the more often
it will cease (keep in mind, ceasing is
not an issue as long as the machine is
not ceased up for an extended period).
The higher RPM gives the buds less
time to align with the grinding blades
and, in turn, will break more stems,
putting them into the final product.

INCREASING the humidity level of
your biomass will DECREASE the
number of stems in the final output.
This is because dry stems snap and
fall apart instead of bending and
staying intact.
DECREASING the humidity level will
INCREASE the number of stems in the
final output. If your material turns into
a paste, instead of being ground, it is
too wet.

INCREASING the angle of the

material will be ground for a smaller
amount of time.
DECREASING the angle of the
machine (1, 3, 6 options) will
INCREASE the amount of stems in
your final output. This is because the
material will be ground for a longer
period of time.

GRINDING MEDIUM & BLADES INSTALLATION & DETAILSGRINDING MEDIUM & BLADES INSTALLATION & DETAILS
The Grinding Medium Assembly is placed onto the Grinding Frame’s studs first and is what
the operator uses to control the size of the output material. The operator must choose what
hole sizing they want to use. The characteristics of each of the hole sizes are outlined below.
When physically installing the assembly, ensure the open end is orientated towards the motor
side of the Grinding Frame, shown on the previous page.
• The 1/8” diameter hole size is the best at filtering unwanted material out of the
output, however, it has the lowest throughput of the three choices.
• The 5/32” diameter hole size is in the middle ground compared to the other sizes.
• The 3/16” diameter hole size is not ideal for filtering unwanted material from the
output however, it has the highest throughput of the three choices.
The Grinding Blades Assembly is the motorized portion of the Grinder and is what moves
the material through the machine. This assembly also gets placed onto the four studs on the
grinding frame and on top of the grinding medium. If the shafts do not align, the blades can
be spun by hand to move the slot into place. The shafts are shown isolated below to help
illustrate this process. Use (4) 1/4-20 wing nuts to secure to frame.
HOPPER INSTALLATION & DETAILS
There are motorized components on this machine that can cause

HOPPER INSTALLATION & DETAILS
The hopper is fixed to the Grinding Blades assembly via two ¼-20 carriage bolts and wing
nuts for quick and toolless installation. This is a vital piece of the machine. It allows the
operator to keep their hands away from the motorized blades when not utilizing the Rise
Conveyor for feeding (highly recommended). Simply loosen the wing nuts on the bolts and
slide the hopper onto the brackets on either side of the opening. Ensure to slide the carriage
bolts between the slot of the brackets. Re-tighten the wing nuts. The bottom of the hopper
walls should be flush with the top of the Grinding Blades assembly, as shown below.
REMOVEABLE ACCESSORIES INSTALLATION & DETAILS

This machine has rotating parts and pinch points that can cause
serious injury. When powering the machine, ensure that all
guards, assemblies, and accessories have been properly installed.
Absolutely no loose hair, clothes, jewelry, or accessories permitted
when operating.
To begin using your machine, plug the power cord into a power source. This should only
be done once the operator is ready to begin grinding and all guards, assemblies, and
accessories have been properly installed. Below is a diagram of the control box and what
each of the inputs control. The red emergency stop button on the front of the box can be
pressed at any time to immediately cut all power to the machine in case of an emergency.
Upon start up, the operator may need to just touch the screen to wake up the software.
After that, the main menu will be showing on the screen, as seen below. To get to the
operation menu, simply tap start grinding. From there you will be presented with the
second screen (see the next page).

844.DRY.TRIM [e-mail] greenbroz.com
From here, you can begin operating your G-lite. The “start” and “stop” buttons are there
for controlling the grinding motor and the “clear jam” button is used for anytime the
motor ceases up. This button will reverse the motor for a pre-set amount of time and
then continue forward again. The amount of time that the motor reverses for should be
kept as short as possible. The only intended use is to just slightly loosen the material in
the grinding volume before returning to grinding. The variable that controls the clear jam
function is in the settings page. It is recommended to keep the variable around 2 seconds
long. If the machine spins in the reverse direction for too long, the material will be pushed
out the front and not be processed.

MACHINE OPERATION & DETAILSMACHINE OPERATION & DETAILS
The front of the machine is equipped with level control that consists of three angles,
1 degree, 3 degrees, and 6 degrees. Using these pre-set angles, the operator is able
to control how long the material spends inside of the machine. At a shallow angle the
material will spend more time being ground. The opposite is true for the machine being
set at a steeper angle. Ideally, there should only be stems and seeds falling out of the
front of the machine into the stem catch. If your desired material is coming from the
front of the machine, the material needs to spend more time being ground. If at the top
setting and desired material is still spilling into the stem catch area, the operator can
rerun the material as needed.
SHUT DOWNSHUT DOWN
• Stop the grinding motor using the HMI on the control box. Ensure the slotted drive is
vertical.

TROUBLESHOOTINGTROUBLESHOOTING
Hopper Not Sitting Correctly
If the operator is noticing excessive material escaping between the Hopper and the top of
the grinding volume, it is likely that the Hopper, or Hopper Brackets, are misaligned. With
the tight tolerances used, misalignment may happen during cleaning or transportation.
• Tools Required: 7/16” Wrench & Soft Hammer
• The Hopper Brackets are not parallel with the grinding volume.
• Double check the bottom of the Hopper Brackets are parallel with the bend lines on
the Grinding Blades housing. If they are not, remove the hopper, loosen the nuts, and
lightly tap them until they are parallel. Retighten the nuts.
Misalignment of Shaft Tab and Slot After Deep Cleaning
If the operator is having difficulty installing the Grinding Blades assembly because the
shafts tab and slot are not aligning, it is likely that the shaft collars were not placed in
the correct position after deep cleaning. It is recommended that only one shaft collar is
removed during deep cleaning to keep the position of the assembly precise.
