When a unit is to be parked for an extended period, it is important to take care to reduce potential issues cause by extended storage. These steps can decrease downtown when the unit is put back into service. Equipment that will not be scheduled for operation for at least 3 months should be considered to be in extended storage. In such cases, Sherman+Reilly recommends the following procedures:
- Clean machine, including the undercarriage. Touch-up paint any chipped or rusted areas to prevent further corrosion.
- Inspect the machine thoroughly and repair any apparent worn or damaged hoses, cables, wiring or components. Check all the bolts and nuts and tighten if necessary.
- Trailer tire pressures should be periodically monitored, as heavy trailer weight on low tires can create permanent buckling of the tire sidewall resulting in the need for tire replacement. Always see the specified air psi ratings listed on the tire sidewall.
- Inspect trailer axle hubs and ensure they are filled with the manufacturer’s recommended lubricant. See www.dextergroup.com for more information.
- Lubricated all grease points. Ensure all Zerk fittings are greased as applicable. Ensure all exposed threads are lubricated.
- Check air filter. Clean and replace as needed.
- Remove dirty engine oil, fill with new oil and run the engine for about 5 minutes to let the oil penetrate to all the parts.
- Ensure fuel tank is full to prevent condensation in the fuel tank. Add winter grade diesel, FAME-free fuel and/or stabilizer additive when appropriate. NOTE: BioDiesel fuel is not suitable for extended storage. Operate the engine for a few minutes so that only stabilized FAME-free fuel is still present in the fuel system.
- If machine is equipped with Diesel Exhaust Fluid (DEF), ensure the tank is full. DEF commonly has a shelf life of 2 years under optimal temperatures which should be taken into consideration when storing the equipment. While DEF is not affected by freezing, its shelf life is shortened when exposed to temperatures greater than 86°F.
- If machine is equipped with a Safe-Zone® cab with a windshield washer bottle, ensure bottle is full of window washer fluid that will not freeze in cold weather.
- Test engine coolant and replace or fill with 50/50 antifreeze and distilled water mixture to prevent freeze damage during cold weather. Run the engine to thoroughly incorporate new any new coolant into the cooling system.
- Disconnect battery and cover terminals, adjust electrolyte level, and recharge it. If stored for extended periods battery may be removed and stored inside a cool, dry place where the batteries can be checked periodically and recharged. Discharged batteries will be damaged if stored below freezing temperatures.
- After the unit has cooled, cover exhaust and intake filter. Exhaust cover must be tightly sealed to prevent moisture from entering the engine, especially if stored outside.
- Regularly apply a corrosion inhibitor to unfinished metal as well as fairlead rollers and pins. If the unit is stored outdoors, the product should be reapplied every 6 months or more frequently if a visual inspection indicates that the surface is no longer glossy.
- If an engine is not used, oil may run off interior engine parts that normally receive lubrication. The lack of lubricant can allow condensation on metal and cause corrosion, especially in areas of high humidity (water content in the air). If storing machine for extended periods of time, run the engine every two to three months for 10 to 15 minutes under no load to keep engine free from rust caused by condensation inside the engine. In areas with high humidity, running the unit more frequently may be necessary.
- If the engine is not run for longer than 5 to 6 months, Kubota® recommends applying enough engine oil to the valve guide and valve stem seal and make sure the valve works smoothly before starting the engine.
- Every 2 to 3 months, it is recommended that all hydraulic motors and cylinders be cycled for 5-10 minutes to prevent valves from sticking, to lubricate seals, rods, and internal surfaces, and to remove moisture from the system. Failure to cycle hydraulic components regularly may allow spot rust, pitting, or degradation of rubber seals which will reduce the efficiency and life of hydraulic components. When storing for an extended period, coat any exposed cylinder shafts with a rust inhibitor that is compatible with hydraulic component seals. Retract all hydraulic piston rods if possible.
- Store machine in a covered dry area if possible.
-
- Place a “DO NOT OPERATE” identifier on the control panel with date procedure was conducted.
- Lockout/Tagout the unit. Many units are equipped with a lockout power switch on the battery box. Remove all ignition keys and store in safe place.
- Cover all exposed control panels with tarps or plastic after the unit has cooled.
- Ensure all cab doors, windows and engine cowling panels are closed properly.
- Lock all lockable panels and cab doors.
Operation After Extended Storage
Prior to initial startup of equipment after 3 or more months of storage, follow these steps to ensure proper operation. If the equipment has not been started for over a year, consult your engine dealer and/or S+R.
- Visual check of overall condition of equipment. Note any leaks or items that need to be replaced and pay special attention to any pneumatic hoses, hydraulic hose assemblies and wiring harnesses.
- Inspect tires and tire pressure. Fill if required.
- Check the engine oil, engine filters, and hydraulic filters.
- Check hydraulic oil, engine coolant, and fuel. Add/Replace as required.
- If applicable, check fuel/water separator and drain if needed. Frequently check separator during first few hours of use and drain as necessary.
- If battery(s) were not removed place on a trickle charger for at least 24 hours before start-up. If battery(s) were removed ensure they are clean and charged before reinstalling.
- Inspect cab for signs of animal inhabitation if equipment was stored outdoors. If signs of animal ingress are present, take special care to inspect the electrical system and any exposed wires.
- If applicable, replace winter weight oils with traditional weight per engine manufacturer’s specifications.
- Remove any engine or exhaust covers before operations.
Once the check list above is completed, follow startup procedure denoted in the Operator’s Manual or engine manufacturer’s manual and take precaution to inspect for drips or leaks as the machine begins to run. During the first day of use, check the machine frequently for hydraulic fluid, fuel, or oil leaks.
Please note: these guidelines are not all-inclusive and are provided to assist in identifying maintenance items and areas to be considered. Harsh climate, exposure to salt spray, and various operational environments may necessitate additional considerations. For specific engine storage and preventative maintenance information, Sherman+Reilly recommends following the engine manufacturer’s guidance. In any instance where this guidance is different than the engine manufacturer’s guidance, the engine manufacturer’s guidance should take precedence. Contact Sherman+Reilly’s Service department for with any questions.
