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.
4
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.

The AL30-A, AL40-A, AL50-A and AL60-A have a slight leak from the inside of the case
to the oil supply orifice. Loosen the oil supply plug one turn and wait a short time for
pressure to release then remove the oil supply plug. As there is a slight leak from inside
the case to the oil supply orifice, set the oil supply to “Max Level” slowly, while ensuring
an oil film is not created over the oil supply orifice.
When removing the oil supply plug, pressure within the case will be released, so ensure
that protective goggles are equipped.
After oil is supplied, after ensuring that it is correctly positioned, the oil supply “O” ring can
be returned to its previous state by gently screwing it in.
(For tightening torque, see 9. REPLACEMENT PROCEDURE)
The AL10-A and AL20-A cannot supply oil under pressure.
After releasing the inlet pressure and checking that there is no internal pressure in the
case, remove the oil supply plug slowly and set oil supply to “Max Level” slowly while
ensuring that an oil film is not created in the oil supply orifice.
Perform periodical check to find cracks, flaws or other deterioration on resin bowl and the
sight dome. If any of them is seen, as malfunction is caused, replace with new bowl or the
sight dome.
Check for dirt in resin bowl periodically. If any dirt is seen, replace with new bowl. And if
removing off the dirt by washing instead of using a replacement, never use washing
material other than neutral detergent. Otherwise, the bowl is damaged.
Open and close drain cock manually. Open and close too much may damage the drain
cock.
Discharge drain to avoid that drain exceeds the upper limit of the air filter. Excessive drain
in the lubricator may cause dripping failure.
Use clean oil to avoid dripping failure.
The lubricating amount should be less than the upper limit of oil level.
5
Use class 1 turbine oil (without additives) ISO VG32. Using other lubricant can cause
damage to devices and result in malfunction.
Check the dripping amount once a day. Dripping failure may cause damage to lubricated
objects.
Avoid rising piping and piping branches on secondary side. Otherwise, lubricating failure
may be caused.
Air Source
Maintenance
Use clean air. Compressed air containing chemicals, organic solvent, synthetic oil or
corrosive gas may lead to cause breakage of parts or malfunction.
Air containing too much moisture may cause malfunction. Install the air drier or the
aftercooler before the lubricator.
Maintenance and checks should be done by following the procedure in the operation
manual. Incorrect handling of the product may cause breakage or malfunction of the
equipment or device.
