Service Tools; Troubleshooting - Stanley DL07 User Manual

Service Guidelines
• Always wear Personal Protection Equipment (PPE) when performing maintenance on the tool.
• Disassemble the tool in a clean area, away from dirt and grit.
• Replace all seals that are exposed during disassembly.
• Inspect all exposed seals for signs of damage or wear. This is a sign of contaminated hydraulic oil or oil that is too hot during operation. Check the
hydraulic system for contamination, if signs exist.
• Use degreasing solvent to clean all removed parts.
• Inspect all removed parts for damage.
• Apply clean grease or O-ring lubricant to all parts prior to reassembly.
• Always determine and correct the cause of a problem before reassembly. Further wear and tool failure can result if the root cause has not been
corrected.
• O-rings and seals should be removed with proper O-ring tools. This will prevent damage to seal groove surfaces.

Troubleshooting

Before servicing the tool:
• Check the hydraulic power unit and ensure it is providing the correct pressure and flow to the tool.
• Check hydraulic hoses and couplers for restrictions or blockages. Also ensure the hoses are connected to the proper ports on the tool.
• Check the hydraulic fluid temperature and ensure it is not too hot (140°F / 60°C) or too cold (50°F / 10°C).
• Ensure the hydraulic power source relief valve is set to open at 2100 PSI (145 BAR).
