Main Body Stand Installation
With the Main Body’s LOGO facing forward, insert it into the stand from top to bottom. Use the provided black fixing ring to slide up from the bottom of the Main Body, fitting it into the Main Body’s slot. -
WDT tool and Handle
Hide the WDT tool inside the handle by clockwise screw. Turn counter-clockwise a half-turn to take out the WDT tool.
-
Drip Tray Usage and Installation
During WDT distribution, operations can be conducted above the drip tray to prevent coffee grounds from scattering on the countertop. After distribution, the drip tray can be placed in the slot beneath the stand, serving as an anti- slip pad for the cup.
Product Installation
Purchase fresh coffee beans from local roasters,
Use filtered water.
Use a coffee scale to precisely measure the amount of coffee beans and the
output of the espresso. Grind the coffee beans in advance before preparing the
espresso. It’s recommended to invest in a high-quality manual grinder.
Before tamping, use the WDT tool to stir and break up clumps for even
distribution, which aids in uniform coffee extraction.
For optimal espresso extraction results, place a 53mm filter paper at the
bottom of the basket, This reduces the fine grounds from passing through the
ilter or clogging the flter holes, affecting the coffee’s taste.
The bottom of the basket is designed as an exposed bottomless filter, allowing
for a clearer observation of the entire coffee extraction process. This design
helps in identify-ing any blockages, dead spots, or uneven extractions.
Usage Instructions
-
Pour the ground coffee into the basket. Then rotate the tail of the handle clockwise to remove the WOT tool and gently stir the coffee ground to break up any clumps, ensuring even distribution.
-
Use the tamper to compact the coffee powder into a solid puck. The integrity and density of the puck are crucial for the quality of the coffee extraction.
-
Once tamping is complete, place the silicone thermal puck screen. The screen ensures that the hot water doesn’t disperse the coffee grounds, while the silicone sleeve minimizes contact between hot water and the stainless-steel surface to prevent temperature drop.
Dosing Range:| 0.560.78 oz /16-22g
---|---
Maximum Water Chamber Capacity:| 2.7oz/80ml
Recommended Water Temperature:
Dark roast beans:| 185°F to 194°F (85°C to 90°C)
Medium roast beans:| 190°F to 198°F (88°C to 92°C)
Light roast beans:| 198°F to 203°F (92°C to 95°C) -
Portafilter and Main Body Installation:
Lift the handle from the bottom left until it contacts the Main Body. Align the handle with the leftside of the LOGO, and after fitting it into the slot, rotate the handle to the right side of the LOGO for a complete assembly.
-
The 8mm quick-connect nozzle at the back of the main body designed to connect to an electric air pump or gas cartridge. After connecting, it provides high-pressure gasto the main body. This high-pressure gas applies force to the hot water inside the basket. As the pressurized hot water passes through the coffee puck, it extracts the coffee, which then flows out from the bottom of the basket. Note: To terminate extraction, press the pressure relief valve to release the high pressure inside the basket, immediately stopping the extraction.
-
When installing the gas cylinder,frst turn the switch clockwise to the end, ensuring the output is completely closed.
Pressure Gauge: After installing the gas cylinder, the pressure typically rises to over 1000psi (depending on the pressure inside the cylinder). When the pressure drops to around 500psi, the output pressure will noticeably be insufficient, suggesting a need to replace the gas cylinder. The pressure gauge reading is affected by temperature. If the ambient temperature is low, the pressure will also decrease.
Use CO2 cartridges with 3/8-24 threads. To install, turn the cartridge clockwise until the pressure gauge needle moves, indicating the interal pressure of the cartridge. If you hear a hissing sound, itindicates an incomplete seal between the cartridge and the valve; continue to turn the cartridge clockwise until the sound disappears.
The 8mm quick connect is the output port, connecting to the input port on the back of the Main Body.
The function of the pressure relief valve is to release the pressure inside the basket after extraction.

How to disassemble and connect the air valve:
For the air valve (air pump), first pull the ring of the 8mm quick connector towards the rear, unlocking it. Align the 8mm female quick connector on the air valve (air pump) with the male connector, release the ring, and it will snap back ntoiits original locked position. The air valve (air pump) is now correctly installed. To detach the air valve (air pump), similarly pull the ring of the Smm female quick connector, unlockingit, allowing for the removal of the air valve (air pump). -
How to use the air valve to pressurize the Maespresso 58 espresso maker:
Oncethe cartridge s installed and connected to the air valve, you can start pressuriz-ing the Maespresso 58 espresso maker. The full name of the air valve is the 10BAR constant pressure throttle valve. Regardless of the pressure n the cartridge (must be higher than 10BAR), the 10BAR constant pressure throttle valve will reduce the output pressure to 10BAR. The function of the air valve switch is to adjust the flow rate of the output gas. Turning it clockwise will increase the output, while turning counterclockwise will decrease the output until fully closed.
Cleaning and Maintenance
Regular inspection and cleaning are crucial, and proper maintenance can ensure the longevity of your Maespresso 58 espresso maker. The design of the Maespresso 58 is simple, and only the basket directly contacts the coffee. Therefore, cleaning should be primarily focused on the basket. Since the Maespresso 58 basket uses a double mesh design, there might be coffee residue in between the two meshes. Here’s how to clean it:
-
Basket:
(1)if cleaned shortly after use, rinse the bottom of the basket with hot water. The remaining coffee will naturally be washed away.
(2)if forgotten about and not cleaned immediately after use, dried coffee will form hard-to-clean stains. Place the basket in boiling water and heat it simultaneously for a few minutes. The boiling water can dissolve the dried coffee. If the cleaning result is still unsatisfactory, extend the boiling time to more than 10 minutes. -
Main Bod,
If there’s moisture or coffee on the Main Body after use, wipe it dry with a cloth or paper towel and place it in a well-ventilated area to air dry. For the air intake (8mm quick connector nozzle), use an appropriate wrench to remove t, then take out the internal filter cotton. Continuous use or misuse (e.g., overfilling with water) can wet the filter cotton. It’s recommended to dry or replace the filter cotton. Finally, let all components air dry for several hours before reassembling.
Precautions
- The maximurm operating pressure should not exceed 11BAR. Exceeding this pressure might damage the equipment or even pose a risk.
- After extraction, ensure that the pressure s fully released (pressure gauge reading at 0) before removing the handle and basket. Never forcibly remove the basket during extraction or f the pressure hasn’t been fully released.
- If using an electric pump as a pressurization tool, pay attention to the cleanliness of the pump and the surrounding environment.
Troubleshooting
To achieve high-quality espresso, it’s crucial to maintain an internal pressure between 8 to 11 bars. For this, the following parameters need to be controlled:
- Coffee grinding amount. I there’s too much ground coffee in the basket,itwillincrease theinternal pressure.
- Coarseness of the coffee grind. Overly fine ground coffee will elevate the intemal pressure. If you consistently can’t extract coffee or only obtain a negligible amount, you should slow down the pressing speed. Grind the coffee beans coarser and reduce the amount of ground coffee. If coffee extraction i too easy and lacks the presence of coffee oils, you need to grind the beans finer. The coffee grind amount can be increased to a ‘maximum of 22 grams.
