When dismantling the bearings of high-pressure Roots blowers, pay attention to the areas where the inner and outer rings are struck to prevent bearing damage. During the maintenance phase, conduct a risk analysis. Before starting work each day, the person in charge should inform the team members about safety precautions. After work, summarize the day's safety performance. Use kerosene and cleaning agents for cleaning components, keeping them away from fire sources. Dispose of used oil and rags promptly in a trash bin.

When using electric tools, ground fault circuit interrupters (GFCI) must be used, and an electrician should be responsible for the wiring. In pneumatic conveying operations, the team leader for each process must provide a safety briefing and anticipate potential dangers.

All disassembled pipelines and pump casing openings connected to the system should be properly covered to prevent foreign objects from entering.

During the dismantling phase, conduct a risk analysis. Before hoisting the motor, ensure an electrical worker disconnects the wires and checks for errors. Use a wheel puller tool to remove couplings, and do not forcibly hammer them.

Be careful to avoid pinching hands when removing drive belts. Use oil pans to catch oil when draining the tank to prevent spills on the floor.

In powder conveying operations, avoid wearing gloves when using a sledgehammer for chipping. Personnel assisting nearby should stay focused to prevent injuries from the hammer.
