COLD WEATHER OPERATION
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.
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 tools; the tool will gum up when anti-freezes are introduced and will not
function properly. The best lubricant for freezing weather is the 1 to 1 oil and kerosene
combination.
c.
If possible, run the air supply line to a indoor located Filter-Regulator-Lubricator or relocate
the F-L-R to a warmer operating area.
AIR CONSUMPTION
Air consumption in cubic feet per minute (cfm) for the SLP can be calculated as follows:
cfm = (a)x(b)x(0.40)
a = Number of straps applied per minute.
b = Number of seconds air motor is on per strap during tensioning, from start
to finish sealing.
0.40 = SLP efficiency ratio.
Example calculation:
(a)x(b)x(0.40)=4x5x0.40=8.0 cubic ft/min.
Peak strapping load is 4 straps/minute, so a=4.
Air motor is on 5 seconds/strap, so b=5.
SLP efficiency ratio is 0.40.
Air pressure is assumed to be 90 psig with the recommended size and length of air hose. Volume
of air at room temperature and sea level pressure, or so-called `free air' conditions. For more
detailed information about air supply systems, refer to Signode manual Part No. 186038.
AIR LINE PRECAUTIONS
Too much air pressure can cause internal tool damage. The maximum operating air pressure for
this tool is 90 psig.
Strap breakage hazard. Strap breakage can result in severe personal injury.
Strap can break during tensioning if inlet air pressure to tool exceeds 90 psig.
Maximum operating air pressure is 90 psig.
