Customer safety and satisfaction is priority.

COFFEEJACK™ has undergone years of vigorous research and development resulting in a robust design, capable of withstanding high pressure and temperature. It is essential that components are sufficiently maintained and that COFFEEJACK™ is used correctly to avoid accidents.





Enjoy superior espresso anywhere, anytime!


Do not use CoffeJack with fragile or unstable mugs/glasses without the use of a CoffeeJack elevation stand. Failure to do so could result in mug/glass damage or spillage of boiling water. Our elevation stand removes all loading force from mugs/glasses and also enables easy storage (available on website).

Do not over-restrict the basket. This could result in seal failure when repetitively exceeding the maximum pressure of the Pressure Relief Valve.

Allow glass to momentarily cool after extraction to prevent injury.

Do not travel without protecting CoffeeJack in a safe and secure case.

Fully remove handle before filling with hot water to prevent spillage.

Always use CoffeJack with the funnel in position. Failure to do so could result in spillage of boiling water.

Do not damage the sealing edge of the basket. The smooth surface is essential to maintaining a high pressure seal.

Do not fill water above Max Fill Line Indicator.

Do not hold the glass whilst securing and/or removal of the basket.

Pump only when CoffeeJack is rested securely on the rim of a strong mug/glass or Elevation Stand (available on website).

Allow CoffeeJack to cool before trying to secure and/or remove the basket. Failure to do so could result in injury from residual hot water within the grind.

Keep away from children.

Avoid leaving the machine unattended during use.

Inspect the machine before use and make sure there is no damage.

If the pressure regulator valve activates (audible sound), reduce pump speed to lower extraction pressure.

Only pour water in the reservoir. Never press the piston if the portafilter is not properly locked and tightened.

Do not try to remove the basket during usage.

In the event of injury from hot water/components, pour cold water on the affected area and call a doctor if necessary.

The machine should be used in conditions between 5°C and 50°C (41°F and 122°F), and under normal atmospheric pressure conditions (from 0 to 3000m altitude).

Do not use the machine for any other purpose than instructed. CoffeeJack would decline all responsibility in event of misuse.
