c. Salt Water Areas. Deterioration and corrosion of exposed metal is greatly accelerated.
All parts of the unit should be wiped dry whenever the unit is shut down. Apply an approved
perservative to all exposed metal parts. Keep unit covered when inoperative.
d. High Altitudes. Compressor efficiency may be reduced as much as 20 percent. This is a
normal condition which cannot be prevented, but maximum performance can be maintained by
taking the following precautions.
Death or serious injury could occur if gasoline is not han-
dled carefully. Use in a well-ventilated area away from
open flame, arcing equipment, ignition sources, heaters
or excessive heat. Engines must be turned off and cool
before refueling. Use proper refueling procedures and
equipment to avoid spillage. Do not run engines near
open gasoline containers. Always store gasoline in pro-
per, marked containers. Do not use gasoline as a clean-
ing solvent. DO NOT SMOKE.
(1) Fill fuel tank at the end of each day to prevent condensation buildup in the tank.
(2) Since the amount of air available to the carburetor will be reduced, adjust carburetor
idle adjustment needle-valve for a higher fuel-air mixture.
