5-4. Nail Driving Force In contrast to a pneumatic nailer, the output energy of a gas nailer cannot be adjusted optionally. However, the output energy is changed because environmental conditions such as ambient temperature, humidity and altitude have an effect on its combustion. Figure 2 shows a comparison between the pneumatic nailers Models NR 90AD and others and the gas nailer Model NR 90GC on the output energy range. The output energy of the Model NR 90GC changes within the operating range from 5.7 kg/cm2 (81.5 psi) to 6.1 kg/cm2 (87.2 psi) as a result of conversion to the air pressure of the pneumatic nailer Model NR 90AD. Choose suitable nails and workpieces according to the output energy of the nailer.

5-4. Nail Driving Force
In contrast to a pneumatic nailer, the output energy of a gas nailer cannot be adjusted optionally.
However, the
output energy is changed because environmental conditions such as ambient temperature, humidity and altitude
have an effect on its combustion.
Figure 2 shows a comparison between the pneumatic nailers Models NR 90AD
and others and the gas nailer Model NR 90GC on the output energy range.
The output energy of the Model
NR 90GC changes within the operating range from 5.7 kg/cm
2
(81.5 psi) to 6.1 kg/cm
2
(87.2 psi) as a result of
conversion to the air pressure of the pneumatic nailer Model NR 90AD.
Choose suitable nails and workpieces
according to the output energy of the nailer.
