be located on the inside wall, preferably with the com-
pressor control equipment. All pressure relief valves
should be tested daily by hand to be sure that they are
functioning properly.
ROTATION -- the compressor must be
run in the proper direction so that the
fan will blow air over the compressor
and for pump to operate. The motor
leads must be connected to give the
required direction of rotation.
“V” BELT DRIVE -- The “V” belt drive consists of a rub-
ber--fabric composition belt operating in a grooved
pulley. Motor adjustment is provided to take up stretch
of belt. The belt should be tensioned as described in
any V--belt suppliers catalog. No belt dressing of any
sort is required. Always install a new belt when belt be-
comes worn.
COVERS AND GUARDS
To avoid personal injury or death from
moving parts all compressor covers
and guards must be securely fas-
tened in their proper positions at all
times when the compressor is operat-
ing. In addition, all moving parts on
the entire compressor package, in-
cluding but not limited to engine or
motors, drive shafts, belts, pulleys,
etc., must be equipped with guards or
covers, which must also be securely
fastened in proper position at all
times when equipment is operating.
Covers and guards are intended to
not only protect against personal in-
jury or death, but to also protect the
equipment from damage from foreign
objects.
STORAGE -- After completing test of the compressor,
a protective type oil to retard rust and corrosion is

sprayed into the suction intake to protect interior of
heads, valves and upper cylinder section. This is done
with unit running.
This treatment gives the compressor sufficient protec-
tion against corrosion for approximately four months
under average conditions. The protective oil in the unit
need not be removed as it will mix with lubricating oils.
If a compressor is stored or not put into use for a period
longer than four months, the following procedure is rec-
ommended:
Remove valves and handhole plates. Inspect the interi-
or for signs of corrosion. Rotate the unit to inspect the
cylinder walls. Use a protective type oil to retard corro-
sion and rust and spray inside the crankcase through
the handhole plates. Spray cylinder bores. Spray
valves and reassemble.
This protective oil spray treatment is
only sufficient for a short period of
time and should not be confused with
long term storage.
PRESTART CHECK -- (New or Overhauled Unit)
1.
Check all bolts and nuts for tightness. Bolt torque
specifications can be found in Parts List Manual.
2.
Inspect air filter and air intake line for dirt and loose
connections.
3.
Service the air filter per instructions in “Air Filter,”
page 5.
