1. Always shift pump clutches with engine clutch disengaged.
2. Do not clash clutch gears when shifting.
3. Close booster valves, drain valves, cooling line and third stage discharge valve before
attempting to prime the pump.
4. Always keep primer shut-off valve closed, except while priming.
5. Re-open and close primer valve to re-prime or eliminate trapped air from suction line.
6. Always drive a midship mounted split-shaft pump with truck transmission in the gear
recommended by the chassis manufacturer.
7. Never run the pump without water in it except momentarily while priming.
8. Accelerate and retard speed of engine gradually.
9. Watch the engine temperature, and start the cooling water at the first signs of overheating.
10. Keep good gaskets in suction hoses, and handle carefully to avoid damage to coupling
threads.
11. Air leakage into suction lines is the most frequent source of trouble when pumping from a
suction lift (draft).
12. Always use a suction strainer when pumping from draft, and a hydrant strainer when pumping
from a hydrant.
13. Foreign matter in impellers is a result of failure to use adequate strainers and is a common
source of trouble.
14. Drain pump immediately after each run. This is especially critical in freezing conditions.
15. Do not run the pump long with discharge completely shut off.
16. Do not close a "Shutoff" nozzle when pumping with motor throttle wide open, unless relief valve
or pressure regulator is set for the correct pressure.
17. Keep the pump gear case filled with oil to the level of the oil level plug/dipstick.
18. Check oil level in the pump transmission after every 25 hours of operation or 3 months, and
changed it after every 50 hours of operation or 6 months.
19. In such equipped transmissions, once the oil is drained, remove the strainer screen oil sump
fitting and thoroughly cleanse in a parts washer or with isopropyl alcohol, ensuring any debris
is washed away.
20. If pump is equipped with a Darley plastallic (injection) packing shaft seal, check the drip rate
frequently, and adjust according to the packing adjustment instruction, as required. The drip
rate may vary between 5 and 60 drops per minute.
21. Work all suction and discharge valves often to ensure free and easy operation.
