Warning
1) There is a danger of sudden action by cylinders if the sliding parts of
machinery are twisted, etc., or changes in forces occur.
In such cases, human injury may occur, e.g. by hands or feet getting caught in the machinery,
or damage to the machinery itself may occur. Therefore, the machine should be designed to
operate smoothly and to avoid such dangers.
2) If there is a chance that the product will pose a hazard to humans, install a
protective over.
If the moving portion of the product will pose a hazard to humans or will damage machinery
or equipment, provide a construction that prevents direct contact with those areas.
3)
Be certain that the secured portions will not loosen.
Be certain to adopt a reliable connecting method if the cylinder is used very frequently or if
it is used in a location that is exposed to a large amount of vibration.
4) Consider the possibility of a power source related malfunction.
For equipment that relies on power sources such as compressed air, electricity, or hydraulic
pressure, adopt a countermeasure to prevent the equipment from causing a hazard to humans
or damage to the equipment in the event of a malfunction.
5) Consider the action of the cylinder in the event of an emergency stop.
Devise a safe system so that if a person engages the emergency stop or if a safety device is
tripped during a system malfunction, such as a power outage, the movement of the cylinder
will not cause a hazard to humans or damage the equipment.
6) Avoid synchronized operation using cylinders only.
Even if multiple pneumatic cylinders are initially set to the same speed, their speeds may vary
due to changes in operating conditions. Therefore, avoid designs where a single load is moved
by synchronizing multiple cylinder operations.
7) Consider the action of the cylinder when restarting after an emergency stop.
Devise a safe design so that the restarting of the cylinder will not pose a hazard to humans or
damage the equipment. Install manually controlled equipment for safety when the actuator
has to be reset to the starting position.
8) Do not disassemble the product or make any modifications, including additional
machining.
Doing so may cause human injury and/or an accident.
9) When a cylinder is used in a clamping, suspending, or lifting mechanism
There is a danger of workpieces 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.
Caution
1) Operate the cylinder component parts within a range such that collision damage
will not occur at the stroke end.
If the piston with moment of inertia collides with or stops at the stroke end due to the
operating conditions, please consider this when selecting the cylinder and take into
account the allowable kinetic energy.
2)
Use a speed controller to adjust the cylinder drive speed, gradually increasing from a
low speed to the desired speed setting.
3) If pressure is applied to the external cylinder parts, there is a possibility that
air will get inside the cylinder from the rod seal section. (Example: inside a
chamber, etc.)
