Precautions for the Operation of Pneumatic Wrenches

Be careful of the position of the switch before operation in order to understand the direction of rotation when operating the intake valve

It is important to ensure compressed air entering the wrench pneumatic motor: clean, dry air with a maximum air pressure of 6.0 bar. Otherwise, hazardous situations such as transmission system failure, speeding, rupture, and incorrect output torque may/inevitably result.

Ensure that all hoses and other connections are properly sized and securely installed, never use damaged, worn or aging air hoses and other connections, and that an emergency shut-off valve is installed on the supply line and that others know where it is installed.

Before operating the machine, it is important to check that there is enough oil in the oil cup, in the absence or absence of lubrication, will speed up the wear of the pneumatic motor blades, resulting in reduced tool performance, maintenance work increased.

The body posture must be balanced and stable, and do not over-magnitude when operating this tool. Prevent and be alert to sudden changes in torque and strength in motion during the opening and operation of the tool.

If the hose is faulty or the connection is broken, a suitable air safety device can be installed on the hose flow and a stabilizer can be used to prevent the hose from swinging without closing the inside of the hose.

This tool is a torque tool with a reaction arm, and the huge torque generated by the machine is absorbed by the reaction arm.

Therefore, the operation must be for the reaction force arm to find a sufficient strength support point. For safety reasons, it is important to stay away from the scope of work of the reactive arm when working on the machine, otherwise it will cause significant or unavoidable damage to the person.
