★Preventative v. Reactive
○Preventive maintenance is based on the theoretical rate of a component’s failure and typically occurs before a
failure happens.
○Reactive maintenance takes place after a problem has occurred and typically costs more money because of down
time.
★Maintenance schedule:
○The maintenance schedule for mechanical parts is factored by hours of operation. For this list, we are assuming
the machine is running for a 40 hour work week.
○A facilities maintenance schedule should be adjusted based on the amount of time the motor is running.
○Daily:
■Clean & wipedown
■Visual inspection
○Weekly:
■Inspect hinges & hinge hardware for loose or backed out bolts
○120 hours: Check belt tension. See belt tensioning instructions for additional detail
○Monthly:
■Inspect the interior of the control stand electrical enclosure for moisture
■Check vertical movement and pivoting for smooth operation.
■Check filter regulator for condensation.
○6 Months: Grease hinges
○20,000 hours (L10 predicted life): Replace bearings, drive belt, motor and gearbox
If you encounter an issue with your Axis that is not described in the following
pages, please contact us at [email protected]
Your PurePressure Axis trichome separator is engineered to go the distance. Make
sure to do the following to ensure long term reliability.
3. Maintenance Schedule

Air Supply & Pneumatic Function
The Axis has a pneumatic assist designed into the function of the
relocating head. The upward travel is controlled by the regulator on
the back of the control stand. The downward travel has an internal
regulator (not shown) that is factory set and requires no maintenance.
This pneumatic circuit allows you to easily raise and lower the
machine by the flip of a toggle switch.
●The compressed air is supplied to a filter regulator. The
moisture trap on the regulator collects condensation that is
created from compressed air.
●To drain the trap, use the valve on the bottom of the regulator.
Loosen to open the valve and drain the moisture. If the system
is energized with air, a mist will shoot out. Do not be alarmed,
as this is normal. Close back the valve before operation.
●This should be checked and drained on a monthly basis or as
needed.

5.1 Machine Travel
Pivoting Function
A food grade grease is used to lubricate the friction components on the Axis.
The following pages highlight the most commonly lubricated components for
optimal functionality of the machine:
The hinge function should be smooth acting without binding or sticking.
Greasing these fittings regularly will flush out particulates and prevent failures.
a. The Axis has 8 zerk fittings used for lubrication. Using a
standard grease gun with a flexible nozzle, grease the fittings.
b. When greasing a zerk fitting, pump in lubrication until you see it
push out from between the hinge components. Wipe away the
excess that comes from between the hinge components.
c. Lubricate the hinges every 6 months or if any binding occurs.
6
Note: PurePressure’s recommend grease is
Molykote G-0051 FM.

5.2 Machine Travel
Latch Pins
The latch pin engagement plates for vertical travel and pivot should be greased. These
pins are important for securing the vessel in the up-position, as well as in either
quadrant for washing. Greasing these fittings will help with consistent engagement
and prevent failures.
●For the vertical travel (image A.)
a. Apply a thin layer of grease to the up position latch plate.
b. Apply the grease in a vertical orientation from the latch hole and down
the vertical ramp.
●For the pivot (image B.)
a. Apply a thin layer of grease to the underside of the top pivot plate.
b. Apply the grease in a smiley pattern similar to the travel pattern of the
pin.
Lubricate these components every 6 months or as needed.

5.3 Machine Travel
Guard Interlock Assembly
The function of this spring loaded assembly is to engage the safety interlock for the
function of your paddle. To prevent both binding and particulate build-up from
migrating, this has to be maintained.
Follow the below steps to maintain the guard interlock assembly. Lubricate these
interlock bolts no less than every 6 months.
a. First, remove the guard and guard hardware.
b. Now, remove the four shoulder bolts holding the lower mount plate
(shown in the image) with a 1/4” allen wrench. Springs will come with
that plate as it is removed.
c. Clean all the parts with a lint-free rag and iso water mixture removing all
the used grease.
d. Apply grease to the shoulder and thread of the bolts.
e. Set all four springs on the top side of the plate and align the component
as shown back inside the receiving end. Make sure all four springs are
seated in both parts.
f. Compress the components and apply the newly greased shoulder bolts
one at a time.

Molykote G-0051 FM.

6.1 Belt Tension
How to properly tension the belt
Belt functionality is one of the keys to optimal success of the machine. Proper belt
tension extends the life of the mechanical components used in operating the axis
drive system.
The following instructions highlight how to tension the belt:
1. Remove the paddle assembly and the vessel from under the Axis. Ensure the
area is clear.
2. Next, lower the head. Make sure you are locked into position from pivoting.
3. Now, turn the power off.
4. Remove the pulley guard pan. Unfasten 6x bolts using a 5/16” hex or flathead
bolt driver.
5. Power on belt tension meter. The tool will beep to let you know its ready. Hold
1” from the belt at the middle of the belt (between the 2 pulleys). Pluck the belt
like a guitar string and record the reading from the meter.
6. Your belt tension should read between 28-29 Hz. If the meter does not read
between these values, you need to tension the belt.
7. Power down the machine to adjust belt tension.
8. Before adjusting tension, take off the following safety guards with a 5/16” hex
driver or flathead screwdriver:
a. Pulley Guard
b. Lower Tray
c. Paddle Drive Cover

6.1.1 Belt Tensioning (continued)
How to properly tension the belt (continued)
9. LOOSEN, but do not remove the 6x paddle drive mount bolts. Use a ¼”
and 3/16” allen socket wrench to loosen.
10. Using a ¼” allen and a 9/16” flat wrench, loosen the 2x jam nuts.
11. Now, we are ready to adjust the 2x belt tensioning bolts. Using a ¼” allen,
equally adjust the bolts clockwise or counterclockwise to change the belt
tension. Clockwise is to tighten the belt, counterclockwise is to loosen the
belt. Make small adjustments to both bolts then use the belt tension meter to
check the tension after each adjustment.
Note – The bearing life is directly affected by belt tension. Running the motor
with belt tension greater than 29 Hz for prolonged periods of time will
decrease bearing life. If you accidentally exceed the recommended belt
tension during the tensioning process, you will not decrease bearing life. Never
exceed 40 Hz in belt tensioning, as you may permanently damage the belt.
12. Tighten the 6x paddle drive mount bolts. You may find after tightening these
bolts that the belt tension will change slightly. This is an iterative process as
you want the final belt tension when everything is tight to land between 28-29
Hz.
13. Tighten the 2x the tension bolts with a ¼” allen. Be sure the 6x padde drive
mount bolts are already tight or you will adjust the belt tension without
meaning to.
14. Lock the jam nuts to prevent the tensioning bolts from moving.
15. Ensure all sheet metal guards and hardware are tightened and secured before
operating.
