Visually inspect water and foam tanks for proper level and gauge readings. If
any debris is present, flush the tanks to protect the pump from wear caused by
dirty water or foam concentrate.

Valve Lubrication
1. On handwheel-type valves, including PM, PMD, etc., first remove old grease
and paint, then use a dry lubricating spray on gears.
2. Lubricate suction threads with a light coat of a good grade, lithium base
grease. For recommended grease, see “Appendix C1: Lube and Sealant
Specifications” on page 115.
Gearbox Lubrication
Incorrect oil types or amounts of oil result in unnecessary high oil temperature
and possible wear or damage. Change the oil every twelve (12) months,
depending on pump usage. All lubricants must meet service rating API GL-5
requirements.
Note: For domestic use, Hale recommends using an SAE EP-90, 80W90 Lubricant
or “RoadRanger” Full Synthetic SAE 50 Transmission Lubricant, manufactured by the
Eaton
® Corporation, or equivalent. For International use, Hale recommends using an
ISO68 lubricant, or equivalent.
