or lowerNote) M27X3.0 is also available as the main unit’s screw pitch specification for the FA-2725 series. Please order using the model number FA-2725F*-S-P3.0 or FA-2725F*-C-P3.0.
Note: "*" will be filled in with "-S" or "-C"
Note: The maximum operation cycle of FA-2725SL is 30 (cycle/min). Note: The piston rod returning force of FA-2725SL is lower than 40.6N (4.14 kgf).

Selection Guideline The FA-FWM-2725 series series has the following three patterns of absorption characteristics depending on the orifice type. Please use the following information as a guideline when making your selection.

Precautions for Use* Do not use this product without carefully reading the attached owner’s manual.
* Ensure that an external stopper (Stopper nut OP-020FB) is also used.
* Do not turn the oil inlet screw located at the bottom of the main unit.
* Ensure that sufficient mounting strength is secured for this product. (As aguideline, it should be 2 to 3 times the maximum drag listed in the catalogue.)* Do not use this product in a vacuum or a location where it may come in contact with oil.
* Ensure that an eccentric load is not applied to the soft absorber(Allowable eccentric angle: within ±2.5°)

Adjustment Method
To adjust, turn the adjustment knob located at the bottom of
the main unit.
* Because the adjustment can be done in an analog manner, avalue between two integers on the indicator can be set.
* Once the adjustment is complete, secure with a lock screw
using a hex wrench.

3 Magnum Series● Screw the eccentric angle adaptor into
the main unit until the cap for the eccentricangle and the piston rod form a tightconnection. While maintaining this position,
fasten the main unit’s nut until secured.
● Use the eccentric angle adaptor whenthe eccentric angle is 2.5°or larger.
● The main unit can also be used as a stopper.
● Use it with a capless soft absorber.
● The maximum operating eccentric angle
with an eccentric angle adaptor is ±10°.
● The caps and the guides for inclined use
are not unbundled.
