4.2 PURPOSE OF CONTROLS (Continued)
CONTROL OR INDICATOR PURPOSE
BLOWDOWN VALVE Vents sump pressure to the atmosphere at shutdown.
ALTERNATOR WARNING LAMP Indication ofimpending shutdown ofcompressor due to al-
ternator failure.
IDLE WARM---UP VALVE Maintains a closed air inlet valve for reduced compressor
load on start---up. When sufficient warm---up is reached,
push idle warm---up button on control panel for full opera-
tion.The valve will reset automatically for start mode after
compressor is shutdown and the air pressure is released.
PRES SURE SELECTOR SWITCH (185H) Allows compressor operation in the ”low” range from 55 to
110 psig (3.8 to 7.6 bar) or in the ”high” range from 55 to
160 psig (3.8 to 11 bar).
4.3 START---UP PROCEDURE
The following procedure should beused to make the
initial start---up of your compressor:
1. Position the compressor on a level surface so that
proper amounts of liquid can be added if neces-
sary.
(I)
2. Check oil and fluid levels both in the engine and
the cooling system(s). Maintain the proper level;
add if necessary.
3. Fill the fuel tank.
4. Crack open one service line.
5. Bleed fuel injection lines if necessary (see Engine
Operator’s Manual).
6. Turn toggle switch to the
“
ON
” position.
7. On Caterpillar engines, in cold weather, engage
cold weather starting aid button. Hold button for
10---30 seconds and then release.
8. Place the pressure selector switch in the ”low”
position (185H).
9. Push the
OVERRIDE
and
ST ART
button. As en-
gine engages, release
ST ART
button, but hold
the
OVERRIDE
button for approximately 5---10
seconds or until engine oil pressure reaches 20
psig (1.4 bar) and then release.
10.Allowforsufficient warm---up ofcompressor,then
push idle warm---up button for full compressor
operation.
11. Close all doors in order to maintain proper noise
control.
12. After the initial run, shut the compressor down
and refill the radiator and compressor fluid sump
as required. Tighten any loose fittings and check
fan belt tension.
.
(I)
The radiator is filled with a 50/50mixture ofethyl-
eneglycol andwater. John Deereand Caterpillar en-
gines receive Supplemental Coolant Additive (SCA)
at the factory before shipment. Refer to your Engine
Operator’s Manual fordetails and specific engine re-
quirements.
4.4 SUBSEQUENT START---UP PROCEDURE
On subsequent starts, follow the procedure ex-
plained below:
1. Check engine oil, water and fuel levels.
2. Check compressor fluid level (should be half of
sight glass).
3. Check dust collectors and clean if necessary.
4. Crack open service valve.
5. Bleed fuel injection lines if necessary (see Engine
Operator’s Manual).
6. Turn toggle switch to the
ON
position.
7. On Caterpillar engines, in cold weather, engage
cold weather starting aid button. Hold button for
10---30 seconds and then release.
8. Place the pressure selector switch in the ”low”
position (185H).
9. Push
OVERRIDE
button and
ST ART
switch. As
engine engages, release
ST ART
switch, but hold
the
OVERRIDE
button for approximately 5---10
seconds or until engine oil pressure reaches 20
psig (1.4 bar), and then release.
10.Allowforsufficient warmupofcompressorbefore
operating.
11. After warm --- up, push idle warm --- up button for
full operation.
4.5 SHUTDOWN PROCEDURE
To shut the compressor down, close the service
valves and runcompressor forapproximately 5min-
utes to allow the compressor to cool down and turn
the ignition switch to the
OFF
position. In case of
emergency whereimmediate shutdown isrequired,
this procedure is not necessary. The ignition switch
should be put in the
OFF
position immediately.
