Initial Inspection/Disposal Criteria

1. Visually inspect for evidence of use (dust, oil, starter seal broken), damage or missing parts.
2. Return to stock if there is no sign of use or damage and date last tested (DLT) does not exceed 12 months.
3. Refurbish as necessary if unit has been used or fueled, damaged, or shelf life is exceeded.
4. Dispose of the unit if it is not economically repairable.

Refurbishment Procedures

A. Cleaning

1. Remove dirt and oil, using detergent or degreaser as necessary.
2. Use pressure washer to remove heavy deposits of oil and grease.
3. Equipment should be repaired and tested as quickly as possible after washing to minimize rust formation on metal parts.

B. Repair

1. Check for loose and/or missing parts or mounting hardware (especially the carburetor and muffler), tighten or replace as needed.
2. Inspect power-head (engine) for freeness of all moving parts, ensuring that the crankshaft, piston/cylinder and all engine bearings are not damaged.
3. Check condition of spark plug, air filter, and fuel filter; clean or replace as needed.
4. Check frame for cracks, repair or replace as necessary.
5. Inspect exhaust system; make sure there are no cracks or leaks. Check for loose and/or missing parts and hardware, tighten or replace as needed.
6. Check throttle linkage, tighten bolts as needed.
7. Ensure all decals (operations and warning) are affixed and legible.
8. Ensure “EMERGENCY RESCUE EQUIPMENT EXEMPT FROM EMISSIONS STANDARDS UNDER 40 CFR 1054.660” decal is affixed.
9. Ensure all gaskets on the pump fittings/adapters are in place and functioning properly.

C. Test for Performance

1. Ensure recoil starter functions properly. Check for damage or fraying of pull cord; repair or replace as necessary.
2. Engine should start easily, run smoothly, be free from fuel leaks, and provide sufficient power to the pump end.
3. Ensure engine controls are operational and functional; stop switch, throttle and choke.
4. Test for performance:
   • Pumps are tested with 1 ½” dia. inlet hose w/foot valve, 1 ½” dia. discharge hose and ¼” nozzle
   • Adjust carburetor: i. Set idle speed to 2400 RPM. ii. To adjust high speed mixture use full throttle and set pump output pressure to 120 PSI. Lean out adjustment screw to achieve max RPM, then richen until pressure drops 5 PSI.
   • Check max PSI with nozzle closed. Minimum pressure: 140 PSI.
5. Use loss of prime method to test engine over-speed protection cut-out switch.
6. Ensure mechanical pump seal is not leaking, repair or replace as necessary.
7. Should any function fail a test, refer to the manufacturer’s repair manual and troubleshooting guide to correct the problem.
8. Lubricate pump head bearing with specified grease.
9. Remove fuel source from engine and run engine until carburetor is completely empty of fuel.
10. Remove all water from pump end.

D. Repackaging 

1. Use nylon “zip-tie” to tie off (seal) starter rope to the frame.
2. Attach certification tag that indicates date last tested (DLT), property #, and name of individual certifying performance.
3. Ensure that all identification (property #, serial #, owner ID) is affixed and legible.
