Maintenance
Warning
(1) 1. Perform maintenance and inspection
according to the procedures indicated in the
operation manual.
If handled improperly, human injury and/or malfunction or
damage of machinery and equipment may occur.
(2) Removal of equipment, and supply/exhaust of
compressed air
Before components are removed, first confirm that measures
are in place to prevent workpieces from dropping, run-away
equipment, etc. Then, cut off the supply air and electric power,
and exhaust all air pressure from the system using the residual
pressure release function.
When the equipment is operated after remounting or
replacement, first confirm that measures are in place to prevent
the lurching of actuators, etc. Then, confirm that the equipment
is operating normally.
(3) Low frequency operation
Valves should be operated at least once every 30 days to
prevent malfunction. (Use caution regarding the air supply.)
(4) If the volume of air leakage increases or the
valve does not operate normally, do not use the
valve. Perform periodic maintenance on the
valve to confirm the operating condition and
check for any air leakage.
Caution
1. Draining
Remove drainage from air filters regularly.
2. Lubrication
In the case of rubber seals, once lubrication has been started, it
must be continued. Use class 1 (no additives) and class 2 (with
additives) ISOVG32 turbine oil. For details about lubricant
manufacturers' brands, refer to the SMC website. If other
lubricant oil is used, it may cause a malfunction.
