Fixed Throttle (
0.8) Mounting Instructions
(20L Tank Unit Type only)
When using the unit with a set pressure of 6 MPa or higher, if the pressure becomes unstable due to the
effects of contaminants, etc., mount the fixed throttle (
0.8) provided as an accessory.
Check that there is no residual pressure before mounting it.
1.
Remove the hexagon socket head plug (Rc 1/8).
2.
Mount the fixed throttle (NPTF1/16
0.8).
3.
Wrap sealing tape around the hexagon socket head plug (Rc 1/8) and fit it as it was.
Mounting the fixed throttle will also change the rotational speed in the pressure holding status, so adjust to
the appropriate speed (EHU**R07 : 350±30 min
-1
, EHU**R10 : 480±30 min
-1
).
Close the hydraulic unit’s discharge port. If the adjustment is performed while connected to the main
machine it will not be possible to adjust to the appropriate rotational speed due to the influence of leakage
from the valves, actuators, etc.
