Regrinding The Driver Blade - Hitachi NR90GC - 3-1/2" Gas Powered Clipped Head Framing Nailer Technical Data And Service Manual

9-4. Regrinding the Driver Blade

The tip of the driver blade should be ground as shown in Fig. 20. To grind with a grinder, gradually grind the tip
while cooling the ground area with water to prevent it from being excessively heated. Excessive grinding will
rapidly reduce the service life of the driver blade. In such a case, replace the driver blade.
