C.3. ANCILLARY EQUIPMENT PREVENTIVE MAINTENANCE PROCEDURES
Regular preventive maintenance assures continued dependable operation of the ancillary
equipment used with the Hale single stage booster pumps. This section provides recommended
actions to be completed for the ancillary equipment listed in this appendix. The pump preventive
maintenance actions listed are scheduled to be completed after each use and on a weekly, quar-
terly and annually basis.
C.3.1 Weekly Maintenance
Perform each the following procedures weekly.
C.3.1.1 Pump Shift Warning Indicator Lights
Verify the parking brake is set and the wheels are chocked to prevent any movement of the ap-
paratus.
A. Follow operating procedures in (Section 3 — OPERATING PROCEDURES) to en-
gage pump if no local procedures exist.
B. Verify warning indicators in cab and on pump control panel function properly.
C. Verify indicator lights on control panel function properly and agree with indica-
tors in cab. Repair or replace any malfunctioning indicators.
C.3.1.2 Check Valves
Properly functioning valves are integral to the proper operation of the pump. Refer to the valve
manual for proper valve maintenance procedures.
A. Lubricate all suction and discharge valves using an approved lubricant.
B. Verify each valve operates easily and closes completely.

tor's panel. Gauges not reading within 10% of the calibrated test gauge must be removed from

Operate the pump drive controls to verify the pump can be engaged. Verify the indicator lights
work properly.
C.3.1.6 Inspect Water and Foam Tanks
