How should I check for leaks in hydraulic hoses?

When pinhole leaks develop in hydraulic lines, take the following steps to identify the locations of leaks and avoid injury: 

  • Before looking for the leak, shut off the power source to the hydraulic pump, and lower the implement to the ground.
  • Relieve the pressure of the hydraulic system by moving the hydraulic control lever back and forth.
  • To locate the leak, pass a piece of cardboard or mirror over the area where you suspect the leak.
  • Fix the leak immediately.

Never use your hand to check for a hydraulic leak. Hydraulic fluid can be under pressures of between 1,000 and 3,000 pounds per square inch (psi). Fluid under this pressure can penetrate the skin, necessitating immediate medical attention.
