OPERATION AT HIGH ALTITUDES.
a.
Due to thinner air at higher altitudes, the air compressor unit will operate at reduced capacity (i.e., the higher
the altitude, the lower the capacity). Engine will produce less power and air compressor will have less air to compress. It
will take longer to arrive at operating pressure and it will be slower to replenish.
b.
Frequently check discharge temperature gage. If air compressor unit overheats, stop use of all tools and
allow air compressor unit to run, unloaded, until it cools down to a more acceptable operating temperature, 185°F (85 °C).
