The notes for Using

Be sure to read this before handling

CAUTION
1. Piping

Before installing the piping, blow compressed air to prevent dirt from entering the piping.

2. Air Supply

Using the compression air with dry via filter. Consider the supply air piping and supply air flow rate toensure sufficient operating speed.

3. Hydraulic Fluid (ISO VG22 Standard mineral hydraulic fluid or VG32)

If the hydraulic fluid has drain or dirt mixed in with it, or if it has deteriorated or discolored, replace it withnew hydraulic fluid. Also, use the same old and new hydraulic oil. Recommended to replace once a year.

4. Quantity of hydraulic fluid

There is an oil level sticker on the side of the oil gauge, so replenish the hydraulic oil if the oil level drops.
When the Power Pack Cylinder operates, the hydraulic oil level in the oil gauge will rise or fall by a few
millimeters. Add hydraulic oil to about the middle of the oil gauge. Please be careful not to add too much
hydraulic oil.

Before using

How to set up and make various adjustments when using the Power Pack Cylinder.
ⒶOil gauge

Mount the Power Pack Cylinder on the equipment and complete all airpiping. A bottle containing oil is included in the package, so remove thered oil cap at part Ⓐ and fill oil about the middle of the oil gauge. Air
bubbles will appear in the oil gauge when the Power Pack Cylinder isoperated manually or automatically. Repeat this operation to bleed air
until no air bubbles appear. It is about 10 times. Bleeding air will reduce
the amount of oil, so add more oil each time. When air bleeding iscompleted successfully, both stroke and thrust will be fully exerted.
Attach the red oil cap.

Adjustment method
Adjust by install a meter-out speed controller
in P2 port.
Adjust by install a meter-out speed controller
in P1 port.
Install regulator with backflow function in P1.
And adjust regulator.
Increase supply air pressure.
Install quick exhaust valve in P4 or P2. (Butthe life of seal shortens.)
Make the air piping thicker and shorter. Also
consider the size of the pneumatic equipment.

CAUTION

Type with oil film removal specification for rod (Symbol : B)
Pipe one-touch fitting to the drain port (Rc1/8) and install a drain pan near
the cylinder. It is no pressure. If oil leaks from the piston rod side, it
prevents the oil leaking from the rod surface and drains it to the drain port.

Drain panType with oil pressure gauge (Symbol : G)
The pressure gauge of a model with pressure gauge is packed
separately, and it is shipped. Mount the Power Pack cylinder in theequipment and attach the pressure gauge before oiling. Remove the R1/4
plug next to the "PRESSURE GAUGE" label. Wrap sealing tape aroundPlug
the threads of the pressure gauge and attach it. Oil will not drip if the plug
Oil pressure gauge is removed with the pressure gauge port pointing upward, butwhen the plug is removed with the cylinder upright, a small amount of oil
will drip. Remove the plug while receiving oil with a waste cloth, etc., andthen attach the pressure gauge. Oiling the oil gauge after installing thepressure gauge. (Refer page 5 “Before using”)

Plug for air release

Troubleshooting guideSituation

The mounting direction for standard use is the piston rod facingdownward.
When using the Power Pack Cylinder horizontally, remove the elbow fromthe oil gauge and attach it directly from the nipple to the cylinder bodywith the red oil cap facing upward.
The standard product cannot be used with the rod facing upward.
Special products purchased as upward facing specifications come withan air bleed plug attached to the width across flats of the piston rod, sobleed the air. Although it can be used by connecting the oil gauge directly
to the cylinder body like the standard, it is easier to bleed air by installingthe oil gauge higher than the air bleed plug as shown in the left diagram.
There is no pressure inside the piping, so connect it with low hydraulicpressure piping. (Cylinder body connection port: Rc1/8, oil gauge
connection nipple: R1/8)

Unable to maintain thrust

Cause of issue
The defective control circuit, no air supply
The malfunctions of pneumatic control
equipment
Power Pack Cylinder is broken
Compressed air is not supplied to P1
Oil is not contained, or insufficient
Seal failure due to seal wear

Countermeasures
Check control circuit, air supply
Check the solenoid valve, speedcontroller, etc
Inquire with us or our distributor
Check the regulator, solenoid valve
Add oil and adjust to proper level
Replace the seal
