these temperatures, add ice or drain and replace it with extreme care to avoid burns and
scalds.
• NEVER add so much ice to your cooling water that the temperature of the water approaches
freezing temperatures, which can damage heated components of the device.
• DO NOT leave this device unattended during use. Pay attention to the pressure gauge and
ALWAYS turn o the power once your desired pressure has been reached.
• For best results, do not use this device continuously for more than one hour at a time. After
each hour of continuous operation, allow enough time for the device to cool completely before
continuing.
• ALWAYS disconnect this device from its power source and release pressurised air between
uses and before any cleaning, repair, or other maintenance. Never touch the pump or
surrounding water while the pump is still connected to power.

ASSEMBLY
1. Place the air compressor (A) on a rm and at surface able to easily bear its weight.
2. If your device came with its temperature gauge disconnected, place two AG13/LR44 alkaline
coin batteries into it, connect the sensor wire to the back of the cylinder head, and insert the
gauge into its position on the compressor housing.
3. Prepare a basin lled with no less than 20 L or 4½ gallons of clean water. For best results, use
distilled water to minimise mineral buildup and contamination.
4. Use one water tube (H) to connect the pump's water outlet to the compressor's lower water
inlet. Connect the other tube to the compressor's upper water outlet and place the other end
where it will drain water back into the pump's basin. Make sure the pump (G) is completely
covered by the cooling water and then connect it to power.
Never touch the pump or surrounding water while it is connected to power. Always turn o
the compressor and unplug the pump rst before making any adjustment.
5. Open the oil ll port and slowly add ISO VG 46 or AW 46 oil until it
reaches the appropriate level on the gauge, a little above halfway full.
Never run the compressor without its oil but do not overll. If
you have added too much oil, prepare a suitable basin, open the
drain port above it, and drain the excess.
6. Install the breather (E) in place of the oil ll port cap.
7. Install the knobs (F) onto the pressure relief and drain valves.
8. Connect the air hose (D) to its port just below the pressure valve, carefully aligning its threading
and tightening completely with a spanner.
9. Connect the power cord (I) to its socket on the compressor and then a stable compatible
power source.
It is highly recommended to use a test plug to check for any leaks upon rst use. Use it
to plug the quick connector and check that system pressure reaches over 275 bars or
4000 psi within 30 seconds.
OPERATION
1. Check the oil level gauge. Your ISO VG 46 or AW 46 oil should reach a little above halfway and
look essentially the same as it did coming out of the bottle. Change your oil once it begins to
darken appreciably.
2. Check the air intake lter for any obstruction. Clean or replace the lter as needed.
3. Prepare your basin with at least 20 L or 4½ gallons of cooling water. Connect the water tubes,
fully submerge the pump, and then plug it in. Wait for the water to return into your basin through
the second tube. Note that, during use, you may add ice to your basin to help keep your water
temperature down but never allow the water itself to become ice cold, which could damage
heated components inside your compressor.

4. Open the pressure release valve ("bleed valve") and drain valve so that your motor will expel
excess humidity and have time to warm up before beginning full operation.
5. Pull back the outer cover from the quick connector, t it onto the device you wish to ll with
pressurised air, and release the cover to lock it in place.
6. Flip the power switch to begin operation. After about a minute of warmup, close the drain and
pressure release valves to allow pressure to begin building. Keep an eye on the temperature
and, once it begins approaching 65°C or 150°F, cool or change out your cooling water while
being careful to avoid scalding yourself. For best results, allow time for your compressor to cool
after each hour of continuous operation.
7. Pay attention to the pressure gauge. Once your desired pressure is reached, turn o the power,
open the pressure release valve, and wait for the pressure gauge to read 0 psi. For best results,
open the water/oil separator to dry or replace its lter, minimising obstruction and corrosion at
its hose connection.
8. Open the drain valve knob to release any trapped humidity. The released water should be milky
white or slightly brown without appreciable smell. If it ever becomes noticeably dark or oily
smelling, change your device's lubricating oil and have a technician check its seals and O-rings
for leaks or wear.
9. Unplug your pump before removing it from your basin.
MAINTENANCE
• Always release any pressurised air and disconnect the device from power before any cleaning,
repair, or other maintenance.
• Clean the exterior of the device with a soft damp cloth after use. Remove light debris from the
air lter with compressed air. Do not use abrasive cleaners or caustic chemicals. Do not get any
electronic components wet and allow time for all parts to fully dry before further use.
• Check the components of the device periodically for any signs of looseness, wear, or damage.
Tighten, repair, or replace any problematic parts before further use.
• Check the level and quality of the oil before each use, changing as necessary. For best results,
change this device's oil at least once within the rst 50 hours of operation. Change the oil at
least once after every 100 hours of use or year of operation thereafter, whichever comes rst.
• Check the air intake lter for any blockage before each use, cleaning or changing as necessary.
Change the lter at least once after every 100 hours of use or year of operation, whichever
comes rst. More frequent changes may be necessary in dusty or dirty environments.
• Replace this device's safety valve and high-pressure air hose at least once after every 1000
hours of use or year of operation, whichever comes rst.
• If this device will not be used for an extended period of time, disconnect it from power, drain all
uids, and store it in a cool dry place away from direct sunlight and inaccessible to children.
