14.2 Check
14.2.1 Air pressure
Checking to see if the air pressure is 0.5 Mpa.
How to adjust the air pressure
1) Connect an air hose to the filter regulator to supply the machine with air.
2) Pull up the pressure knob, and turn it around to adjust the air pressure so that it
can be within 0.5 ± 0.05 Mpa.
3) If oil or water is pooled in the drain, exhaust it.
Note: The air pressure is adjusted at the factory. Check the pressure level.
CAUTION
To prevent the body from injury which can be caused by accidental
activation of the machine, turn off the power of the machine before
following the operation above.
