Consult SMC if using this product for purposes other than its primary use of lubricating air line
equipment.
Selection
Installation
Connect the lubricator ensuring the direction of " " (IN) and " " (OUT) for air direction or
an arrow. Wrong connection may cause malfunction.
The use at high frequency such as the use in press machine may damage internal
components and cause operating failure of the equipments installed to outlet side. Contact
SMC for such a use.
Small air consumption may prevent the oil from dropping. Confirm air flow necessary to
produce the drops required for the correct amount of oil.
Do not supply the air from outlet side (reverse air flow). Otherwise, internal components may
be damaged.
Note that the numbered scale markings are guidelines for adjusting the position, and not
indicators of the dripping amount.(AL20-A
～
AL60-A)
Do not install in areas of high humid or high temperature. It causes damage of the product
and malfunction.
Make space to provide easy access at the bottom of the product when replacing bowl or
draining. The required space is shown on
「
11. DIMENSIONS
」
(P26).
If piping is branched at inlet side, the oil may flow back. Avoid the reverse flow by installing a
check valve (AKM series) to inlet side.
Adjustment
Adjustment of the oil adjustment valve should be carried out manually. The use of tools, etc.
can result in damage to the unit.(AL20-A
～
AL60-A)
Install the bowl vertically with bowl facing down. If it is inclined, dripping may not be confirmed.
Do not drop nor apply impact during transportation or installation. This can cause damage to
the product.
Turning the oil adjustment valve counterclockwise increases the dripping amount, and turning
it clockwise reduces the dripping amount. From the fully closed position, three rotations will
bring it to the fully open position. Please do not rotate it any further than this.
Piping
Blow out or clean piping before piping to eliminate swarf, cutting oil, solid foreign material.
Contamination of piping may cause damage or malfunction.
When installing piping, avoid chips and sealing materials from piping screws entering the
inside of equipment. Or malfunction may occur. When use sealing tapes, leave 1.5
～
2
threads of the end of thread exposed.

Hold the female screw side and screw in piping with recommended tightening torque.
Insufficient tightening torque lead to cause loose piping or sealing failure. Excessive torque
may lead to cause screw breakage. Tightening without holding female screw side applies
excessive force to the piping bracket which lead to cause breakage.
Increase the cylinder volume in relation to the tube capacity between the solenoid valve and
the cylinder. If the cylinder capacity is less than that of the tube connecting the cylinder and
solenoid valve, there is a chance that oil may not be carried correctly.
Before using an SMC fitting and S coupler, please refer to "Tightening the threaded portion of
the connection thread" of the Fittings & Tubing Precautions.
Do not apply any torsional moment, or bending moment except the weight of the lubricator itself.
External piping needs to be supported separately. Hard piping like steel tube is susceptible to
excessive moment load or vibration. Insert the flexible tube to cancel the influence.
