Add oil to crankcase according to lubrication
instructions (paragraph 9).
Turn on electrical service and place toggle
switch (2, fig.6) on magnetic motor starter
box to on (up) position.
Allow equipment to operate until operating

Place toggle switch (2, fig.6) on mag -
netic motor starter box to on (up) position.
Unless operating pressure is already indi-
cated on pressure gage,
equipment
may operate for up to 21 minutes to build
up pressure.
When operating pressure is reached, open
globe valve assembly by rotating fully
counterclockwise.
b. To shut down air compressor for a prolonged
period, proceed as follows:
1. Place toggle switch on magnetic motor
starter box to off (down) position.
2. Disconnect air hose assembly and allow
compressed air to bleed off.
3. Close globe valve assembly by rotating

Check oil level at oil level gage (17, fig.9). If necessary, add oil (paragraph
9).
Drain moisture from air receiver by opening drain cock (20, fig.8).
Turn off air compressor at end of days operation and close globe valve assembly.
Turn off air compressor.
Clean dust and foreign matter from cylinder head,
motor, fan blade, air lines, inter-cooler, and air receiver. Pay particular atten-
tion to baffles.
Turn off air compressor. Remove muffler assemblies and clean them with gasoline
or any commercial solvent other than carbon tetrachloride.
Check V belts for tightness.
Belts should be tight enough to prevent slipping. If
necessary, adjust belt tension to allow approximately 3/8 inch depression (para-
graph 14).
Change oil (paragraph 9).
Use soap solution and brush to check entire equipment for air leakage around
fittings, connections, and gaskets.
Tighten all nuts and cap screws.
Check and clean compressor valves (paragraphs 17 and 28). Replace springs,
discs, and seats when worn or damaged.
