General
Examine the equipment for leaks or damage
Do this task when the pump is running and the system is pressurized.
1. Look for hydraulic fluid leaks. Pay attention to these areas:
 Hydraulic fluid tank access cover
 Hydraulic connections
 Valves
 Top and bottom decks
2. Examine the low-pressure pipes and the hoses for leaks.
3. Examine the high-pressure tubing for leaks.
4. Examine the weep holes and leak points at both of the high-pressure ends for leaks. Water seeping from a
weep hole is a sign of a faulty part, a loose connection, or a damaged connection.
Identify the source of a leak and correct the problem. Refer to
Leaks
on page 163.
WARNING
Do not touch a hot surface.
Fittings can get hot, especially when they are not tightened properly.
CAUTION
Failure to correct the cause of a leak can cause damage to the water fittings.
