FAQ

Q: What are the common faults of the 30mm Air Impact Wrench and their handling methods?

Fault	Reason	Exclusion method
The machine does not rotate or operates abnormally	The rotor end face is jammed against the front and rear cover planes. 2. The slide is too long, too thick, or excessively worn, or the slide has broken and is jammed. 3. The parts are not clean or the lubricating oil viscosity is too high.	1. Adjust the gap between the rotor and the front and rear covers. 2. Sharpen or replace the new slide plates to ensure they move flexibly within the rotor slots. 3. Clean the parts and select lubricating oil with appropriate viscosity.
Torque drop	1. The rotational speed is abnormal. 2. The impact claw has poor contact or severe wear. 3. The impactor spring is broken or has failed.	1. Adjust the engine. 2. Repair the impact claws or reequip them. 3. Replace the new spring.
Increased air consumption	1. The compressed air pipeline and all connection points are leaking air. 2. The slide does not meet the specified dimensions or is excessively worn. 3.The gap between the rotor and the front and rear covers is too large.	1. Inspect the pipeline and all connection points to eliminate gas leakage. 2. Replace the new slide. 3. Adjust the engine clearance.

Q: What are the precautions for using the 30mm Air Impact Wrench?

A: 1.The air pressure should be maintained at a gauge pressure of 0.40 to 0.50 megapascals. Good oil mist lubricators and water separators should be installed on the pipeline. The rubber hoses must be intact, connections should be secure, and sealing must be ensured.
2.Machines must not run idle for a long time under high pressure to prevent wear of components and performance degradation. When work is completed, the air inlet passage should be plugged with a stopper to prevent dirt from entering the machine interior. If the machine needs to be stored in a warehouse, a small amount of high-viscosity lubricating oil should be injected at the joint, and then run under low pressure for several seconds to prevent rusting.
3.For machine lubrication, the prime mover uses HJ-10 (GB443-84) machine oil. Bearings, gears, and impact mechanisms are selected with ZG-2 (GB491-87) calcium-based grease. If the pipeline is not equipped with an oil mist lubricator, an appropriate amount of lubricating oil should be injected at the joint before each start-up.
4.Machines should be regularly maintained. The maintenance period depends on the degree of use. Each time maintenance is performed, the parts must be cleaned thoroughly, and the damaged parts should be repaired or replaced with new ones.
