4.2 PURPOSE OF CONTROLS (Continued)
CONTROL OR INDICATOR PURPOSE
BLOWDOWN VALV E Vents sump pressure to the atmosphere at shutdown.
IDLE WARM---UP CONTROL Maintains a closed air inlet valve for reduced compressor
load on start---up. After engine starts, turn the handle of the
selector valve from the “start” to the “run” position for full
operation within the first minute of operation.
4.3 ST ART-- UP PROCEDURE
The following procedure should be used 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. Drain water from the fuel---water
separator.
4. Crack open one service line.
5. Bleed fuel injection lines if necessary (see Engine
Operator’ s Manual).
6. Turn the warm---up control selector valve to the
start position.
7. In cold weather, engage cold weather starting aid
button. Hold button for 5---10 seconds and then
release.
8. Press the engine switch to the “ON” position.
9. Press the engine switch to the “START” position
momentarily to engage starter, when engine
starts release switch.
10. After the engine starts, turn the idle warm---up se-
lector valve from start to run for full compressor
operation within the first 30 seconds of operation.
After 30 seconds, the annunciator light will go off.
11. Close canopy 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 re-
quired. Tighten any loose fittings a nd check fan
belt tension.
(I) The radiator is filled with a 50/50 mixture of ethyl-
ene glycol a nd wa ter. All engines receive Supple-
mental Coolant Additive (SCA) at the factory before
shipment. Refer to your Engine Operator’s Manual
for details and specific engine requirements.
4.4 SUBSEQUENT START-- UP PROCEDURE
On subsequent starts, follow t he procedure ex-
plained below:
1. Check engine oil, water and fuel levels.
2. Check compressor fluid level (should be visible in
sight glass). Drain water from t he fuel---water
separator.
3. Check dust collectors a nd clean if necessary.
4. Crack open service valve.
5. Bleed fuel injection lines if necessary (see Engine
Operator’ s Manual).
6. Turn the warm---up control selector valve to the
start position.
7. In cold weather, engage cold weather starting aid
button. Hold button for 5---10 seconds and then
release.
8. Press the engine switch to the “ON” position.
9. Press t he engine switch to the “START” position
momentarily to engage starter, when engine
starts release switch.
10. Allow for sufficient warm up of compressor before
operating.
11. After the engine starts, turn the idle warm---up se-
lector valve from the start to run position for full
operation within the first 30 seconds of operation.
4.5 SHUTDOWN PROCEDURE
To shut the compressor down, clos e the service
valves and run compressor for approximately 5 min-
utes to allow t he compressor to cool down and
press the engine switch to the OFF position. In
case of emergency where immediate shutdown is
required, this procedure is not necessary. The en-
gine switch should be pressed to the OFF position
immediately.
