Editor’s note: In the October issue of FireRescue, several of our extrication contributors provided some tips for cleaning, maintaining and using hydraulic tools. But we figured it’s also good to go to the experts. Following are tool maintenance tips from Hurst.
Top 10 Hydraulic Rescue Tool Maintenance Tips from Hurst Jaws of Life
- Protect hydraulic tools against moisture when in storage and make sure there is adequate space to prevent damage to hoses, connectors or tool itself.
- Inspect tools carefully for hydraulic leaks daily and inspect hoses and couplings for wear and damage.
- Check control valve operation for easy operation and free return to neutral and check inside frame yolks for dirt and debris.
- Check that all fasteners (nuts, bolts, screws and retaining rings) are in place and securely fastened and check the blades for damage daily.
- Before storage, connect the pigtail hoses to each other and move the throttle control in both directions to equalize pressure in the system.
- Every six months, remove and inspect retainer rings, links and link pins and replace if necessary. And, remove locknut, pivot pin, blades and washers and inspect for damage and wear and replace if necessary.
- Lubricate all friction areas generously with a high temperature grease every six months and re-assemble components.
- Check operating pressure, unloaded through full operation cycle, each year.
- Pressure-check all valves and internal seals each year and replace as required. Verify all hoses and couplings are not worn or damaged.
- Check opening and closing times of the tool annually and replace operation decals if necessary.
