Trouble 

Major causes 

Countermeasures 

Piston speed is 

too slow. 

1. Too small 

directional 

control valve. 

- Use a valve of a larger size. 

 

 

2. Too large 

resistance of 

equipment used 

on the way of 

piping 

- Use valves and equipment of an appropriate size

 

- In particular, attention should be paid to the piping

 

and fittings because they are often missed. 

Equipment and piping at the exhaust side should 

also be of an appropriate size. 

 

The product 

sometimes does 

not operate. 

1. Operation at a 

very low speed 

-

 

Operation at a very low speed can create a 

condition with almost no pressure difference 

between the supply side and exhaust side and 

lower sealing effect, which can cause operation 

failure. Keep the specified speed for operation. 

2. Problem of 

equipment other 

than this product 

- Check all items in the system one by one to find 

the cause. 

The product has 

become unable to 

operate. 

1. Damage of piston 

seal 

- Check that the exhaust port of the valve is 

exhausting all the time. - Replace the cylinder with 

a new one. 

2. Problem of 

equipment other 

than this product 

- Check all items in the system one by one to find 

the cause. 

3. Insufficient 

pressure 

- Supply appropriate pressure. 

The piston rod 

has been 

deformed and 

broken. 

1. Operation at high 

speed 

- Operation at a high speed can cause impact, and 

deform and damage the product. Keep within the 

specified piston speed range. 

2. Excessive 

external force 

- It may cause damage and deformation of the 

cylinder if the mechanism interferes or eccentric 

load or over load is applied to it. Remove these 

factors. 

Piston speed 

cannot be 

adjusted with the 

speed controller. 

1. Incorrect speed 

controller 

selection 

- Use a speed controller of a suitable size for the 

required speed. 

2. Problem of the 

speed controller. 

- Replace the speed controller with a new one.
