CHAPTER 9
WEEKLY MAINTENANCE
Maintenance Procedures
DANGER: Never Remove Accumulator Safety cover When Pressure Is Present in The Variable-Stroke Pump
Accumulator!
Preferably Friday evening or the last workday of the week, perform the following maintenance steps:

Clean the high pressure relief valve system and accumulators.

Clean fluid filter with proper solvent.

Bleed all water traps, compressor system and water trap located on air manifold (on pump pivot support
bracket) (see Figure 30).
Check and fill the following lubrication systems:

Check air motor pump oiler attached to power head, (see Figure 31) and fill lubrication systems if
needed.
(Figure 30. Bleed Water Traps) (Figure 31. Fill Pump Oiler)
DANGER: Failure To Clean Pressure Relief Valve System Can Result In Rupture Of Accumulators, Hoses, Or
Heaters!
Clean both pump accumulators on a weekly basis, as well as the high-pressure release valve (located between
the variable-ratio pump and its filter) using the following procedure:

Disassemble both accumulators, the filter, and the high pressure relief valve (see Figures 32, 33, 34).

Remove charging valve caps from accumulators. Shield eyes from valve and release all air and fluid
pressure charge from accumulators. (Refer to “REMOVE PRESSURE,” and “REMOVE AIR
PRESSURE.”).
 FLUID “PUMP R” AND “pump h”: shaft lubrication cups must be filled to 1” depth (see Figure 35).
Check pump shaft for signs of gelled material which indicates a need to replace pump shaft packings.
