Hand tools and pneumatic tools are widely applied in factory operation and equipment maintenance. Poor maintenance will lead to rapid wear and frequent faults, raising procurement costs. This article introduces maintenance standards and quick troubleshooting methods for common tools.
Wrenches, screwdrivers, pliers and files shall be cleaned of scrap iron and oil after use. Store them on dedicated racks to prevent deformation caused by heavy pressure. Apply thin anti-rust oil on metal surfaces regularly, especially in humid workshops. Never use extra sleeves to increase torque, which may cause crack and damage. Repair or replace tools with curled edges or gaps to avoid slipping risks.
Compressed air quality greatly affects the service life of pneumatic tools. Install oil-water separators to filter moisture and impurities. Inject special pneumatic tool oil from the air inlet before daily work, and run the tool idly to spread lubricant evenly. Drain residual water from pipelines after work. Seal the air inlet and apply protective oil for long-term storage. Check air pipes and connectors regularly, and replace aging parts in time.
Causes include low air pressure, blocked filter, worn blades and lack of lubrication. Adjust air pressure to rated range, clean filters and pipelines, add lubricant, and replace worn blades when necessary.
Air leakage is usually caused by aging seals, loose joints and damaged pipes. Tighten connectors and replace defective sealing rings. Do not use adhesive tape to repair cracked air pipes, replace the whole pipe directly.
Foreign matters inside the body or worn bearings will cause jamming and noise. Dismantle and clean the tool, fill lubricating grease fully, and replace worn bearings timely.
Keep complete records of tool purchase, inspection and replacement. Stock vulnerable parts such as seals, bearings, pneumatic blades and quick connectors. Classify and store tools reasonably to improve management efficiency and extend service life.
