5. Trial Operation
Read safety precautions starting on page 10 before performing trial operation.
（

）
Check that the power voltage is at the specified voltage.
（

）
Set the pressure adjusting handle to the lowest state during trial operation, and
check the turning direction of the pump in inching (shortly turn on and off the switch).
When it is rotating in the reversed direction, change the connection of 2 cables out of
the 3 cables.

As for the operating pressure for chucking, first lower to the lowest pressure, and
then set to low pressure at which the chucking action is possible (0.35-0.5MPa) to
check the following.
○
Is it operating smoothly?
○
Is the operating direction correct? (Opening and closing direction of the chuck)
○
Is the operating stroke appropriate? (Jaw stroke of the chuck)
○
Is there any oil leakage with each piping?
If they are normal, gradually raise the operating pressure up to the rated pressure
while checking the items specified above.
At this point, check that the drainage is flowing smoothly.

Rotate the lathe spindle by setting the rotation speed to the minimum. If there is no
run-out of the cylinder or no abnormalities in the support and piping, gradually raise
the rotation speed.
If the rotation vibration is too excessive, run-out of the adapter must be inspected
again.
（

）
If the oil temperature is low (20-30
℃
) or less, run it in at about 1/3 of the maximum
rotation speed.
・
When the ambient temperature of the cylinder suddenly rises, for example, thermal
effect is received from heating of the pulley, etc., or when there is a special heat
generation source around the cylinder, the cylinder charged pressure rises and then
the cylinder may stop operation, if it is continuously operated for a long period of
time without switching operation, since a lock mechanism is built in such a
phenomenon occurs more frequently especially at the time of running in, therefore,
frequently reciprocate the piston.
