The nice tool

I bought this key clash in lieu of 150157 Mecafer ([...]). At the time I did not ask me the couple. But I soon realized that 345 Nm are often not enough.
With this key KS Tools, however, I am confident. I started to use it on a mower clutch without possibility of setting the room properly disassemble. But with this couple, the simple inertia of the assembly is sufficient.
Caution, however, comment indicated the need to purchase the grease syringe to lubricate the tools. This is false, lubrication is done either automatically or manually by the air supply. See extract from the manual attachment.
