Small Engine Equipment
Storage and Shelf Life Checks:
Storage and Shelf Life Procedure:
Date Last Tested (DLT) not to exceed 12 months
Initial Inspection/Disposal Criteria
- Visually inspect for evidence of use (dust, oil, starter seal broken), damage or missing parts.
- Return to stock if there is no sign of use or damage and date last tested (DLT) does not exceed 12 months.
- Refurbish as necessary if unit has been used or fueled, damaged, or shelf life is exceeded.
- Dispose of the unit if it is not economically repairable.
- Remove dirt and oil using compressed air or detergent and shop towels as necessary.
- Use pressure washer and degreaser to remove heavy deposits of oil and grease.
- Equipment should be repaired and tested as quickly as possible after pressure washing to minimize rust formation on metal parts.
- Check for loose or missing parts and mounting hardware. Tighten or replace as necessary.
- Ensure that the air filter is clean and dry before reinstalling. Replace the filter if it is damaged or will not come clean.
- Replace spark plug and fuel filter if saw shows normal signs of field use. Use only solid terminal spark plugs
- Test function of rewind starter, ensure proper engagement of engine and recoil function. Check for damage or fraying of pull cord; repair or replace as necessary.
- Ensure all decals (operations and warning) are affixed and legible.
- Ensure fuel geyser danger sticker is present and legible. Reference cache memo 17-2 below.
- Inspect power-head (engine) for freeness of all moving parts, ensuring that the crankshaft, piston/cylinder, and all engine bearings are not damaged.
- Clean muffler of excess carbon.
- Inspect spark arrestor screen for build-up. Clean, repair or replace as necessary.
- Replace sprocket or star drum if the wear is deep enough to catch a fingernail. Inspect clutch shoes and springs. Replace if damaged or missing. Replace clutch drum if badly burned (discolored).
- Clean and re-grease the clutch bearing, replace if needle bearings are pitted or damaged.
- Ensure saw chain is properly sharpened to manufacturer’s specifications after each use. Replace chain if: Cutters have been filed down to 50% or less of the original cutter length; two or more cutters are broken; tie straps are worn down to rivets; if stretched beyond tensioning abilities; or when side plate is filed back to rear attaching rivet.
- Service the guide bar after each use. Inspect groove depth and width; true and file rails; and inspect for bends. Replace guide bar if rails are cracked, chipped, burned, or have a dip deeper than 1/16”. Inspect sprocket tip for wear and looseness. Lubricate tip if grease type.
C. Test for Performance
- Refer to the owner’s manual for operations and specifications information specific to chainsaw model.
- Should any function fail a test, refer to the manufacturer’s repair manual.
- Check condition of fuel mix; ensure fuel is fresh and the correct mix oil ratio is used prior to starting the engine. Use a fuel stabilizer in fuel during testing to help ensure proper operation of engine at post storage start up.
- Ensure recoil starter functions properly. Check for damage or fraying of pull cord; repair or replace as necessary.
- Start saw and allow engine to warm-up at idle.
- Ensure that there are no leaks at engine, fuel tank or bar oil tank.
- Run saw and inspect for proper function of bar oiler and chain brake.
- Ensure all engine controls are operational.
- Inspect engine speed using a digital tachometer, adjust carburetor to obtain specified speed.
- If saw chain rotates at the specified idle speed, inspect clutch for loose and or missing springs.
- Should any function fail a test, refer to the manufacturer’s repair manual and troubleshooting guide to correct the problem.
- Remove all fuel from fuel tank and run engine until carburetor is completely empty of fuel.
- Remove bar and chain oil from the oil tank (local cache option).
- Attach bar guard on cutting attachment
- Use a nylon “zip-tie” to tie off (seal) starter rope to the handlebar.
- Attach a certification tag that indicates date last tested (DLT), property #, and name of inspector certifying the performance.
- Ensure that all identification (property #, serial #, owner ID) is affixed and legible.
