Use this Log to record all maintenance actions and problems (faults, part replacements, tear
downs, and major overhauls – as a minimum). Please contact Customer Services at Hale Prod-
ucts Inc. prior to any proposed return of either a single part, or a complete assembly.

To make the most effective Log always fill in every Log cell for each entry as follows as a mini-
mum.
Enter the DATE: chronology, this is important as loose pages may get out-of-order.
Enter the HOURS RUN: the accumulated hour of run time is important for adjusting the recom-
mended maintenance intervals. These intervals should be adjusted (especially if a shorter inter-
val is suggested by the data) since an individual pumps operating environment can vary widely.
Clean verses dirty water sources, ambient operating temperature for the geographical location or
mounting location, and other key factors should be considered for planned/scheduled mainte-
nance purposes.
Enter the MAINTENANCE/PROBLEM: enter ALL maintenance actions (especially those listed in
Table 7 although items listed in Table 8 should NOT be ignored or excluded) and problems the
pump encounters. The more complete the Log, the more time saved if/when troubleshooting is
required and good (or bad) maintenance practices become highly visible. A PUMPS HISTORY CAN
BE INVALUABLE TO A TRAINED TECHNICIAN.
Enter the PART(S) USED: enter ALL parts replaced. It is important to list not only the assemblies
and components replaced but always include the little things: hoses, connectors, fasteners,
seals, thread lock, etc. The replacement of the little things can be just as critical (or even more
critical) as the big items when it comes to maintaining a pump.
Enter the REASON REPLACED: be as specific as possible (use a cross referenced add-in page(s) if
necessary) when recording a failure, entering a % of wear for a scheduled replacement part is
recommended if attempting to adjust the scheduled interval.
Enter the INITIALS: of the person (or persons) performing/witnessing/recording the maintenance
action or problem for the associated pump.
4.3.
Extreme Conditions Maintenance Guidelines
Extreme conditions occur when the pump has been operated during freezing weather or when
pumping from a water source that contains material that is harmful to the pump if not purged as
soon as possible. Extreme conditions indicate a need for increased maintenance. The proce-
dures in this section identifies only two extreme conditions however many others exist (too nu-
merous to list). The time and cost of the additional measures needed to ensure continued pump
life and dependability are always far exceeded by the cost savings achieved from their perfor-
mance. The following procedures are general in nature, always follow local maintenance and test
procedures when they exist.
4.3.1
Freezing Weather
Drain the volute and discharge valves. If the gearbox is equipped with a water cooling line, drain
this line also. There should be drains for the gauge lines, the cooling line to the engine, and to
the relief valve (if equipped). All of these should be opened until all water is drained out, then
close the drain valves.
