5.1 GENERAL MAINTENANCE
The following procedures are for normal use and conditions. Extreme condi-
tions may indicate a need for increased maintenance. The procedures in this
section identify measures needed to ensure lengthened pump life and continu-
ing dependability. Always follow local maintenance and test procedures.
Wherever there is a requirement for new parts, it is recommended to use only
Hale authorized replacement parts for optimum safety of the equipment and its
operators and to limit “downtime.”
For a parts breakdown and identification, see Section 7, “Drawing Package” on
page 53.
READ ALL INSTRUCTIONS THOROUGHLY
BEFORE BEGINNING ANY SERVICE REPAIR.
Weekly
Priming System Test
1. Tighten all pump caps, and close all pump valves.
2. Pull the primer control while you watch for a below-zero (0) reading on the
master intake gauge.
3. Continue operation for two (2) or three (3) seconds after the primer starts
flushing water to clear any possible dirt or sludge (gum) buildup. This
buildup affects primer operation by jamming vanes which reduces primer
life.
4. Verify that the master intake gauge readings hold for approximately five (5)
minutes after you release the primer control. A drop of up to 10” Hg. during
this 5 minute period is anticipated per NFPA 1901 standards.
5. If air leaks are heard or the gauge bounces back to or above zero (0), the
pump or valves require service.
