Tensioner Maintenance
Always wear impact-resistant eye and face protection when involved with or near the operation, repair or maintenance of the tool or changing accessories on the tool.
Disconnect the power supply and depressurize the hydraulic system before disconnecting or connecting hoses, fittings, or accessories or adjusting or dismantling the tool.
During assembly and maintenance of the tensioning tools, threaded components should be lubricated and protected with a thin coating of anti-sieze compound such as Copaslip or Molyslip in order to prevent rust forming on the screw threads and additionally prevent threaded components from seizing together during use.
Prior to installation, the seals, the bearing strips and wiper seals should have the leading edges lubricated with a suitable light grease, such as Rocol Aqua-Sil. This will aid assembly.
The tool should be fully refurbished once every 12 months.
Inspected for any signs of corrosion. Tools that have evidence of corrosion should be returned to Customer Center.
After every use: check for any oil weeping from the fitting or the adaptor pieces. Any adaptors or fittings that are leaking should be tightened to 25 Nm. Any adaptor or fitting that continues to leak after being tightened should be replaced.
Lifting eyes and straps on tools should be checked before usage. Check for cracks or any other visible damage. Lifting straps or eyebolts which are found to be damaged should not be used.
The tool should not be dropped or hit by other objects as this might cause damage to the sealing surfaces of the tool, which can result in tool failure during usage.
The tool coating should be routinely inspected and checked for any evidence of cracking or flaking. It is recommended that tools that have evidence of flaking or cracking should be returned to Customer Center.
If at any time you have doubts about the operational suitability, please contact Atlas Copco Customer Center for advice.
