Hydraulic Solenoid Function
The 225 amp fuse is for the hydraulic circuit protection. A standard mill use one fuse while a super mill or LT70 use two fuses. Periodic checks for corrosion and loose connections should be done. A bad connection at the fuse mountings can cause excessive amp draw and will damage the fuses as well as cause the studs and nuts to over heat.
