4.3 START-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
necessary. (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. For “H” models, turn the pressure
selector switch to the “low” 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 30 seconds (the annunciator light will go off
after 30 seconds) turn the idle warm-up selector
valve from “START” to “RUN” for full compressor
operation.
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 required. Tighten any loose fittings and check
fan belt tension.
4.4 SUBSEQUENT START-UP PROCEDURE
On subsequent starts, follow the procedure
explained below:
1. Check engine oil, water and fuel levels.
2. Check compressor fluid level (should be visible in
sight glass). Drain water from the fuel-water
separator.
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 the warm-up control selector valve to the
start position. For “H” models, turn the pressure
selector switch to the “low” 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. Allow for sufficient warm up of compressor
before operating.
11. After 30 seconds (the annunciator light will go off
after 30 seconds) turn the idle warm-up selector
valve from “START” to “RUN” for full compressor
operation.
4.5 SHUTDOWN PROCEDURE
To shut the compressor down, close the service
valves and run compressor for approximately 5 min-
utes to allow the 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
engine switch should be pressed to the OFF posi-
tion immediately.
(I) The radiator is filled with a 50/50 mixture of ethylene glycol and water. All engines receive Supplemental Coolant
Additive (SCA) at the factory before shipment. Refer to your Engine Operator’s Manual for details and specific engine
requirements.
4.2 PURPOSE OF CONTROLS (CONTINUED)
CONTROL OR INDICATOR PURPOSE
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.
PRESSURE SELECTOR SWITCH (“H” MODELS) Allows compressor operation in the ”low” range from 85 to
110 psig (5.9 to 7.6 bar) or in the “high” range from 85 to 160
psig (5.9 to 11 bar) for “H” models.
