Step 4:
Trimming the Dose
The adjustable Razor™ Dose Trimming Tool
allows you to trim the puck to the right level
for a consistent extraction.
Select the correct width blade of the Razor™
to match the diameter of your filter basket.
The Razor™ has three blades of varying widths:
58mm, 54mm and 50mm. The 58mm and
54mm are already fitted within the Razor™
body. The 50mm is separate.
If you require the 50mm blade, turn the
adjustment dial past #1 until the 54mm blade
54mm
is fully extended and able to be pulled from
the body.
If you require the 50mm blade, turn the
Adjustable Dial past #1 until the 54mm blade
is fully extended and able to be pulled from
the body.
54mm
NOTE
The Adjustable Dial may feel tight as you
continue to wind it towards the end of its travel.
Insert the 50mm blade into the body. Wind
the Adjustable Dial until the blade is retracted
past #4. Press the 50mm and 58mm blades at
the same time, towards the centre of the body
until a "click" sound can be heard.

After tamping the coffee, insert the Razor™
into the filter basket until it rests on the rim of
the basket. The blade of the dosing tool should
penetrate the surface of the tamped coffee.
If the blade does not penetrate the surface
of the tamped coffee, your coffee is under
dosed. Increase the amount of dosed coffee
by adjusting the GRIND TIME dial.
Rotate the Razor™ back and forth while holding
the portafilter on an angle over the knock box
to trim off a little excess coffee.
