Regular maintenance
Regular maintenance is a schedule of continuous systematic maintenance, designed to
prevent frequent or major breakdowns before they occur.
WARNING: Maintenance on a fire pump should not be done on the fire line. Always
check your pump unit immediately after use.
After each use:
1. Visually inspect the pump unit.
2. Make sure the mechanical rotary seal is not leaking.
3. Check the pump for external leaks.
4. Check the condition of the flexible buffer coupling. Replace if worn. See instructions for
removing the pump end from the engine using the quick release pump clamp.
5. Check the engine for leaks.
6. Clean any dirt or debris from the pump unit. If necessary, a mild soap and water
solution can be used.
7. Clean air filter.
8. Make sure cooling passages and cylinder fins are clean.
9. Make sure that spark plug is cleaned and has proper gap setting.
10. Check throttle and choke control for proper operation.
11. Check fuel line and fittings for signs of wear, etc.
12. Check starter rope and mechanisms and replace if there are signs of wear.
13. Make sure electronic ignition module is free of debris. Verify condition of wiring and
connectors.
14. Note and report any performance irregularities or any abnormal mechanical sounds.
15. Make sure all necessary tools, spares, and accessories are with the pump.
Long-term storage
1. Completely drain the pump of all water.
2. Drain the carburetor. The engine can be run at idle with the fuel line disconnected until
the engine stops to drain the system.
3. Pour 5 mL (0.17 oz.) of 4-cycle engine oil (any viscosity will do). Slowly crank the
engine to cover the piston rings, cylinder and crankshaft with oil to protect the
components from corrosion. Storage seal fogging oil can also be used.
Important: 2-cycle mixing oil is not recommended as preservation oil; it tends to attract
moisture.
4. Follow any other products, components, apparatus, and departmental procedures
and/or guidelines before placing the unit in storage.
