1. Specifications
1.1 Air regulator unit
The regulator that regulates the air pressure supplied to the air drive section of this machine is located behind
the front lower left panel of the main unit. Specify the appropriate air pressure setting shown below.

Supply air pressure
This is the pressure of the source air supplied to the machine. Before setting the air pressure with the air regulator, make
sure that this supply air pressure is in the following optimal range.
Z:LEX (YSM20, YSM20W) : 0.45MPa to 0.70MPa
n
Digital pressure gauge
When within the normal range, the air pressure displays in green. When the air pressure is beyond the upper/lower limit
values (air down detection), an error occurs, and the air pressure displays in red.
n
Set pressure and air-down detection pressure
Air pressure setting for machine : 0.40MPa (±0.01)
(When the air pressure reaches 0.45MPa, the air pressure display turns red.)
Pressure-drop detection level : 0.33MPa
n
Air supply/exhaust switch (valve)
Turning this switch to the right shuts off air supply and exhausts air that remains inside the machine.
n
Source air connector
Prepare an air hose with an inner diameter of at least 8 mm having a 40SH socket (Nitto Koki, or equivalent), and
connect it to this connector. Use dry, clean air passed through an air filter.

WARNING
TO AVOID THE RISK OF ELECTRICAL SHOCK, MAKE SURE THAT THE POWER SOURCE IS OFF BEFORE CONNECTING THE
POWER CABLE. ALSO MAKE SURE THAT THE GROUND CABLE IS SECURELY CONNECTED TO THE MACHINE.
