If equipped with 24 volt compressor (Cold Start
Option)
S
Press and hold the BYPASS button for ten (10) to fif-
teen (15) seconds. This operates the 24 volt compres-
sor which pressurizes the inlet valve and holds it
closed for easier starting.
S
Press both the START and the BYPASS buttons to
crank the engine. DO NOT OPERATE THE STARTER
MOTOR FOR MORE THAN TEN (10) SECONDS
WITHOUT ALLOWING AT LEAST ONE MINUTE
COOLING TIME BETWEEN START ATTEMPTS.
CAUTION
Ether is an extremely volatile, high flammable gas.
Use Sparingly! If too much is injected, the uncon-
trolled explosion may result in costly damage to
the engine.
In cold weather:
In cold weather, as required, press the ETHER IN-
JECT button once or twice only while the engine is
cranking. This injects a measured amount of ETHER
to the engine.
Release the START button when the engine starts and
sustains running. If the engine does not start after a
couple of attempts, Refer to Trouble Shooting Section.
Release
BYPASS button when the engine speed
reaches 1000 rpm. The engine oil pressure should be
above 20 psi. If the engine oil pressure does not rise
within five (5) seconds, stop the unit and refer to
Engine Operator’s Manual.
Once running, All DIAGNOSTIC lamps should be off.
If not, stop the machine and investigate.
Observe the gauges while the unit warms up for five (5)
to ten (10) minutes or until the coolant temperature
reaches 140
°
F (60
°
C).
Push the SERVICE AIR button. The engine should go
to full speed and the discharge pressure rise to slightly
over rated pressure. If there is no air being consumed,
the compressor will unload (intake should be throttled
or closed) and the engine speed drop to the no load
speed.
•
Compressor is now ready to furnish air when the
service valve is opened.
STOPPING
•
Close air service valve (s).
•
Allow the unit to run at “no load” for 3 to 5 minutes to
reduce the engine temperatures
•
Flip all toggle switches to “Off”.
Note: Once the engine stops, the automatic
blowdown valve will begin to relieve all pressure
from the receiver--separator system.
CAUTION
Never allow the unit to sit stopped with pressure in
the receiver--separator system. As a precaution,
open the service valve.
WARNING
Even after pressure is relieved from the
receiver--separator system, any air supply line
from the compressor to a tool or machine could
remain under pressure and cause very serious
personal injury or death.
After the compressor stops, carefully open a valve
at any tool or machine to exhaust the pressure in
any line prior to removal or servicing.
CAUTION
When the machine is connected for operation, its
system
will
become
pressurized
and/or
contaminated if it is stopped with the service valve
open. Any volume of air downstream of the
compressor will flow back into the compressor
through the open service valve. A check valve is
required as close to the service valve as possible
to prevent reverse flow.
