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.

5. Ensure all gaskets on the pump fittings/adapters are in place and functioning properly.

C. Test for Performance

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 pump performance (see owner’s manual for specific performance data).
5. Ensure pump packing or mechanical seal is not leaking, repair or replace as necessary.

D. Repackaging

1. Use nylon “zip-tie” to tie off (seal) starter rope to the frame.
