5 – Preventive maintenance

Examine the pump for leaks or damage

Do this every work shift.
Do this task when the pump is running and the system is pressurized.
1. Look for hydraulic fluid leaks. Monitor these areas:
 Hydraulic fluid tank access cover
 Hydraulic connections
 Valves
 Top and bottom pump decks
2. Examine the low-pressure tubes and the hoses for leaks.
3. Examine the bleed-down valve for leaks or damage.
4. Examine the weep holes in the high-pressure ends for leaks. Water leaking from a weep hole is a sign of a
faulty part or a loose connection.
