Before disassembly or reassembly, be sure to disconnect the air hose from the nailer (with your

10-1. General Precautions in Disassembly and Reassembly

Apply grease (ATTOLUB No. 2) (Code No. 317918) to the O-rings and O-rings' sliding portions.
When installing the O-rings, be careful not to damage the O-rings and prevent dirt entry.
Oil required: Hitachi pneumatic tool lubricant
30 cc (1 oz) Oil feeder (Code No. 877153)
120 cc (4 oz) Oil feeder (Code No. 874042)
1 ltr (1 quart ) Can (Code No. 876212)
If the Gasket [6] is damaged, replace it and check that no air is leaking.
Be especially careful to prevent the entry of foreign particles into the control valve section.
Use the conventional grip tape for repair of the Grip Rubber [46] because the Grip Rubber [46] cannot be
mounted without the specifically designed jig.
