Pneumatic wrench ( air impact wrench ) is a commonly used pneumatic tool, and frequent maintenance can prolong its service life. Here are some maintenance tips.
1. The compressed air should be clean, free from moisture and sweat, please use an air filter. Pneumatic wrenches need to be lubricated before and after use
a. Before lubricating, please unplug the high-pressure air source
b. Press the trigger and add 3-5CC special lubricating oil for pneumatic tools from the air intake head.
c. Connect the high-pressure air source, turn the tool forward and backward for 20 seconds, and the lubricating oil will be discharged from the vent hole (do not point the vent hole at the human body to avoid injury).
d. It must be maintained once every three months to check and clean all parts. When not in use, lubricate and store them to prevent rust inside the machine.
2. The lubricating oil (butter) of the action frame group needs to be lubricated and maintained once a month.
a. Unplug the tool from the air line, open the screw on the front cover, or open the front cover directly.
b. Apply a proper amount of butter to the inside of the front cover and the action frame group, and then lock the front cover.
c. Connect the air pressure tube, gently start the trigger and idle for 20-30 seconds, and let the butter lubricate the entire action frame group.
