Precautions
］
a.
Disassembling the product will void SMC’s warranty. If disassembly is really necessary it is
recommended to fully understand the internal construction before disassembling the products.
b.
Do not damage the seals when reassembling the product.
Be sure to add grease to all the seals and sliding surfaces of the bodies and vane shaft.
c.
Use caution to prevent any damage to the sliding surfaces of the bodies (A) and (B) and vane shaft.
d.
As the rubber of the vane shaft is baked to adhere to the vane, it cannot be removed.
e.
If locking adhesive is applied to the bolts or screws, apply locking adhesive again during re-assembly.
Standard Type (For CRB10, 15)
●
Be sure to install an air filter to clean the supply air.
●
Do not disassemble the actuator.
When disassembling it for an unavoidable reason, follow the
procedures
below, and prevent dust and/or foreign matter from entering the product. (As operation
failure is caused by
an increase in the internal leakage in most of the cases, the speed controller needs
to be readjusted.
It is recommended to operate the product in the stable speed adjustable range (see
"Speed adjustable range" on
page 1)
