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 pressure washing to minimize rust formation on metal parts.

B. Repair

1. Check for loose and/or missing parts or mounting hardware; tighten or replace as needed.
2. Check condition of spark plug, air filter, and fuel filter; clean or replace as needed.
3. Inspect power-head (engine) for freeness of all moving parts, ensuring that the crankshaft, piston/cylinder and all engine bearings are not damaged.
4. Inspect exhaust system; make sure there are no cracks or leaks. Clean spark arrestor of excess carbon build-up, replace screen if damaged.
5. Ensure all decals (operations and warning) are affixed and legible.
6. Check to make sure that all gaskets on the pump fittings/adapters are in place and functioning properly.

C. Test for Performance

1. Refer to the owner’s manual for operations and specifications information specific to pump model.
2. Check condition of fuel mix. Ensure fuel is fresh and the correct mix oil ratio is used for running tests.
3. Ensure recoil starter functions properly. Check for damage or fraying of pull cord; repair or replace as necessary.
4. Ensure pump packing or mechanical seal is not leaking; repair or replace as necessary.
5. Should any function fail a test, refer to the manufacturer’s repair manual and troubleshooting guide to correct the problem.
6. Remove all gasoline from fuel tank and run engine until carburetor is completely empty of fuel.
7. Remove all water from pump end. Grease pump as necessary.

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.
