3-4 How to connect pipes
Connect the main line pipe from the machine to be
lubricated to the pump discharge port (M10X1).
Connect the controlled air for driving the pump to the
pump air port (Rc 1/8).
As the main line pipe, use a high-strength pipe
that can withstand the operating pressure of more
than 3.0 MPa.
First tighten the pipe by hand until it does not turn any
further. Then set a wrench on the pipe and turn the
wrench two to three full revolutions to further tighten
the pipe.
For information on proper tightening torque, refer
to “Pipe tightening torque.”
After piping work is complete, make sure that there is no
leakage of oil from joints.
Discharge pressure and air supply pressure
Adjust the air supply pressure in the range from 0.35
MPa to 0.5 MPa (indicated by the diagonally shaded
area).

4. Controlling the pump
Install a timer on a machine to be lubricated, and make
the operation and pause cycle settings of the three-way
solenoid valve for driving the pump.
Make sure that you make this setting in the
operation/pause cycle. In continuous operation
(when the power is turned on), oil is discharged
through the valve only once. After that, no oil is
discharged, so that points of lubrication will be in
an unlubricated condition.
The solenoid valve for air supply must be a
three-way solenoid valve. Air in the pump is
discharged through the three-way solenoid valve
during a pause.
The pump on the machine side is powered on.
The solenoid-valve timer for driving the pump on the machine
side is on.
The solenoid-valve timer for putting the pump on the machine
side into pause mode is on.
The timers in and above turn on and off repeatedly as
illustrated below.

5. Lubricating oil and refilling
5-1 Lubricating oil to be used
Use industrial lubricating oil in the range from 10 to 100
mm2/s of ISO viscosity.
Do not use any lubricating oil other than that
which has been recommended.
Use lubricating oil of the same grade made by the
same manufacturer.
5-2 Refilling lubricating oil
Refill lubricating oil when the level gauge on the tank
shows “L.”
Refill it through the refill port that you find above the
pump flange.
Use new lubricating oil. If lubricating oil contains
any foreign substances, clogging may occur,
causing the pump to stop discharging oil.
If lubricating oil overflows or leaks, wipe off the
overflowing or leaking oil.
“L” level

6. Maintenance
6-1 Suction filter
Replace the suction filter once a year or clean it
periodically.
If the suction filter is clogged or contaminated, the
oil suction performance will deteriorate and
lubricating oil will not be able to reach points of
lubrication.
Replacing or cleaning the suction filter Mounting plate
1) Remove the pump from the oil feeding
tank.
Remove it with the mounting plate
attached.
2) Remove the suction filter.
Use a wrench to hold the nipple on the
suction side so that the nipple does not
turn together with the suction filter.
3) Replace the suction filter with a new
one or clean the suction filter.
4) Assemble a new suction filter or a
cleaned suction filter to the pump.
Make sure that the o-ring is set on the
thread part.
5) Mount the pump on the oil feeding
tank.
Before conducting maintenance on the pump, turn
off the power and make sure that the pump is not
operating. Conducting maintenance with the
power turned on will increase the risk of the
operator getting an electric shock or the fingers
being pinched in moving parts of the pump drive
unit. Also make sure that the supply of air is cut at
the air supply source.

6-2 Troubleshooting
When troubles occur, take the measures as defined in the chart below.
Trouble Cause Measures to take
No oil discharged
from pump
Low oil level Refill the same oil in use
Refer to“5. Lubricating
oil and refilling”
Clogged suction filter Clean or replace filter, or
change oil to new oil
Refer to“6-1 Suction
filter”
Damage in the tubing in-
side the pump(Twisted,
crashed, or disconnected)
Tighten or replace the conn-
ecting parts
Viscosity is too high, so
that oil can not be sucked
Recheck oil in use and repl-
ace it to proper oil
Refer to“5. Lubricating
oil and refilling”
Pressure in main
tubing is not built
up
No oil discharged from
pump due to any of above
causes
Refer to above measures
Air in the tubing Operate pump and bleed air
in tubing
Oil leaking from pump di-
scharge port or pipe conn-
ection parts on machine
(Due to looseness or exce-
ssive tightness)
Tighten them with proper
torque or re-pipe them
For proper torque refer
to ”Tightening Level for
Connecting Sections” of
the next page
Damaged tubing Replace damaged tubing

15
Trouble Cause Measures to take
Air in the system Air in the system due to
above reasons
Refer to above measures for
“Air in the pump” and “Air
in the tubing”
Due to low level of oil in
tank, air is introduced
into pump
Refill tank with same or eq-
uivalent oil and then bleed
air
No oil discharged
from valve(S)
Pressure does not increase Refer to above measures for
“Pressure in main tubing is
not built up”
Viscosity is too high, so
the reaming pressure are
not relieved completely
Check oil and change oil to
proper oil
Refer to“5. Lubricating
oil and refilling”

Appendix. Oil Contamination
Causes and Measures
■Causes
Causes for contamination can be divided into two categories.
○Before the completion of installation
Foreign particles in the tubing or pump tank.
(Manufacturing defects of the assembly parts or connecting
parts and unconformity during construction.)
○During operation
Foreign particles from outside or generated inside of the
system.
(Condensation of the moisture in the air due to change in
temperature or sludge by oxidation of lubrication oil itself.)
■ Measures
1. Clean the tank and remove the remove the foreign particles.
2. Keep the oil for refilling in the proper place.
If the system is installed and/or oil is stored outdoors, proper
care must be taken since introduction of dust or rain into
the oil would lead to system malfunction.
