Warning
(1) Precautions for model selection
The compatibility of the product is the responsibility of the person who designs the pneumatic
equipment or decides its specifications.
(2) Use within the specified range
If the condition exceeds the specified operating range, it will cause excessive impact or vibration to
the stopper cylinder, leading to possible damages.
(3) There is a possibility of dangerous sudden action by air cylinders if sliding parts of
machinery are twisted due to external forces, etc.
In such cases, human injury may occur; e.g., by catching hands or feet in the machinery, or
damage to the machinery itself may occur.
Therefore, the machine should be designed to avoid such dangers.
(4) A protective cover is recommended to minimize the risk of personal injury.
If a stationary object and moving parts of a cylinder are in close proximity, personal injury may
occur. Design the structure to avoid contact with the human body.
(5) Securely tighten all stationary parts and connected parts so that they will not become loose.
When a cylinder operates with high frequency or a cylinder is installed where there is a lot of
vibration, ensure that all parts remain secure.
(6) Consider a possible loss of power source.
Measures should be taken to protect against human injury and equipment damage in the event
that there is a loss of power to equipment controlled by air pressure, electricity or hydraulics, etc.
(7) Consider emergency stops.
Design so that human injury and/or damage to machinery and equipment will not be caused
when machinery is stopped by a safety device under abnormal conditions, a power outage
or a manual emergency stop.
(8) Consider the action when operation is restarted after an emergency stop or abnormal stop.
Design the machinery so that human injury or equipment damage will not occur upon restart of
operation. When the cylinder has to be reset at the starting position, install manual safety equipment.
(9) When a cylinder is used in a clamping, suspending and lifting mechanism
There is a danger of work pieces dropping if there is a decrease of thrust due to a drop in circuit
pressure caused by a power outage, etc. Therefore, safety equipment should be installed to prevent
damage to machinery and/or human injury.
