Nail Selection - Hitachi NR 90AD Technical Data And Service Manual

5-3. Nail Selection

The Model NR 90AD utilizes D-head (clipped head) nails collated with paper tape.
Applicable nail dimensions are shown below. Please note that screw-type nails cannot be used with the Model
NR 90AD.
CAUTION: Ensure that nails are as specified in Fig. 1. The Model NR 90AD utilizes D-head (clipped
head) nails collated at an angle of 35 degrees which are the same as the nails utilized by P.
However, some D-head nails made by other makers are collated at a different angle of 26
degrees. Use of such nails will cause clogging of nails and subsequent damage to the
nailer. Also avoid use of misaligned nails or nails collated with a weak paper tape. Do not
use P's 2" Roundrive nail (eccentric full round head nail) with the Model NR 90AD because it
may cause bending of nails. It is recommended to use genuine HITACHI nails to ensure
satisfactory driving quality.
