1. Products mentioned in this catalog are not designed
1. Check that the lock nut is tightened.
2. Confirm the degree of rotation of the needle valve.
3. Do not use tools such as pliers to rotate the handle.
4. Confirm air flow direction.
5. Adjust needle by opening the needle slowly after
6. Do not apply excessive force or shock to the body

for the use as stop valve with zero air leakage.
A certain amount of leakage is allowed in the product's specifi-
cations.
A loose lock nut may cause actuator speed changes.
Products mentioned in this catalog are retainer type so that the
needle is not removed completely. Over rotation will cause
damage.
It can cause idle rotation of the handle or damage.
Mounting backwards is dangerous, because the speed
adjustment needle will not work and the actuator may lurch
suddenly.
having closed it completely.
Loose needle valves may cause unexpected sudden actuator
extension. When needle valve is turned clockwise, it is closed
and cylinder speed decreases. When needle valve is turned
counter clockwise, it is open and cylinder speed increases.
or fittings with an impact tool.
It can cause damage or air leakage.
