Do Not Breathe Air!
Discharge air can contain Carbon Monoxide and
other contaminants. Breathing the air can cause
severe injury or death.
High Pressure Air!
● High pressure air can cause severe injury or death.
Be careful when air compressor is operating.
Pressurized air can blow out of safety relief valves
and etc. at incredibly high velocities.
●When using compressed air to clean equipment,
use extreme caution and/or wear eye protection.
●Before servicing the air compressor, stop it,
disconnect the power, and relieve pressure before
removing filter, plug, fitting or cover.
Rotating Parts!
●Keep hands and rods, etc. away from the rotating
parts (Cooling fans, etc.)
●Use caution at all times, when air compressor is
powered. The air compressor may be capable of
restarting without hitting the START button.
●When the air compressor is operating, do not
remove or open the enclosure panels and doors.
●Before servicing the air compressor, stop it, dis-
connect the power, especially when accessing
any rotating parts.
Electric Shock Hazard!
● Before servicing or wiring the air compressor,
disconnect the power. This will prevent anyone
from turning on the power and causing an electric
shock that could lead to severe injury or death.
● Do not allow any unlicensed person to wire the air
compressor. Always use a licensed electrician.
●Ground the air compressor.
WARNING WARNING
WARNING
WARNING
Hot Surface!
●Do not directly touch the air end, discharge air
pipe,and coolers when the air compressor is
operating and immediately after it has stopped,
because these parts are heated then.
●
Before servicing the air compressor (especially
when accessing to the heated parts), stop it, discon-
nect the power, and wait until it is cooled down.
WARNING
CAUTION
Preoaution against Fire!
● Keep any other hazardous materials such as
flammable solvents away from the air compressor.
Also do not use fire nearby it; otherwise a spark
may enter the air compressor and burn it internally.
●Do not remove any protective relayʼs. Also do
not make a modification of the control circuit that
may result in impairing the protective relayʼs
function. Remember that the loss of the protective
relayʼs function may cause serious damage.
●Install an earth leakage circuit breaker between
the air compressor and the power supply. Do not
use a disconnector such as a knife switch
because it cannot protect the air compressor and
may cause burnout of the air end if a ground fault
has occurred.

Lubricating oil circulates in the cooler and piping during
operation, so the position of the oil level differs when the
compressor is running and when it is off. The level rises
when the compressor stops running.

3.3 How to Use the liquid Crystal Display (LCD)
About the LCD Backlight
(1) In the event that no button has been used for 10
minutes, the LCD backlight automatically turns OFF
for protection to the display panel. It comes ON
again if any button is pressed, other than the
START and STOP buttons.
(2) If an event happens while the LCD backlight is off,
the backlight automatically turns ON and stays ON
as long as the event exists. Remote and instant
stop mode can't be set by the LCD monitor.
Set after referring to “3.4 How to Use the Digital
Monitor.” ( page 21)
■Monitoring Displays
There are three monitoring displays: M1, M2, and
M3. To move between these displays, press the
MONITOR button.
3. OPERATING THE DSP [How to Use the Liquid Crystal Display (LCD)]
■Message Display
There is only one message display: M3 (the contents,
however, vary from time to time). It is available only
when some event (air compressor alarm or shutdown,
maintenance notice, etc.) has occurred. Once an event
happens, however, the M3 message display appears
immediately and automatically. From the M3 display,
pressing the MONITOR button will switch the LCD
to the M1 or M2 monitoring displays; but after
approximately ten (10) seconds, the M1 or M2 moni-
toring displays will revert back to the M3 display.
