COLD WEATHER OPERATION
Signode pneumatic powered tools operate reliably in a wide range of operating temperatures.
However, operating conditions below an ambient temperate of 41° F (5° C) may require the
compressed air to be dried. Dried air typically avoids any moisture and freezing tool issues.
Air motors typically use air compressed from 70 psi to 90 psi (4.8 to 6.2 Bar) and exhaust the
compressed air approximately at 15 psi (1 Bar). The highly compressed air cycled through the
tool, then exhausted to atmospheric pressure, may result in the discharged air freezing. Freezing
air will contribute to reduced motor and tool performance.
Freezing air (icing) is a problem to all compressed air driven motors. Factors which can
contribute to icing are:
• Compressed air vs. ambient air temperatures.
• Compressed air vs. ambient air dew points.
• Compressed air pressure.
• Flow rate of the compressed air exhausted through tool.
• Contaminated air quality.
• Cycle rate of tool.
If a tool does not operate satisfactorily in freezing temperatures, certain steps can correct the
problem. The following steps can be taken to improve cold weather operation of the tool:
a. Use of an air line dryer adjacent to the compressor.
b. Use lubricant recommended by Signode. Signode has tested the use of anti-freezes, none
work well in air tool; the tool will gum up when anti-freezes are introduced and will not
function properly.
c. If possible, run the air supply line to a indoor located Filter-Regulator-Lubricator or relocate
the F-R-L to a warmer operating area.
d. Eliminate any air line restrictions (review "Air Supply Installation" in this manual).
