DX225LC-3 Safety 1-46 Preservation/Storing Machine Perform the following if storing excavator for more than one month. Conditions Maintenance Required Cleaning Pressure wash undercarriage and track assemblies. Inspect for damage or loose or missing parts. Lubrication Perform all daily lubrication procedures. Apply a coating of light oil to exposed plated metal surfaces, such as hydraulic cylinder rods, etc. Apply a coating of light oil to all control linkages and control cylinders (control valve spools, etc.) Battery Turn "OFF" the battery disconnect switch. Cooling System Inspect coolant recovery tank to make sure that antifreeze level in system is at correct level.
Every 90 days, use a hydrometer to measure protection level of coolant. Refer to “Antifreeze Concentration Tables” on page 4-94, to determine amount of protection cooling system requires. Add coolant as required. Hydraulic System Once a month, start engine and follow procedures in “Hydraulic System Warm-up” on page 3-12, listed in this manual. 1. Complete the preceding steps. 2. Wash machine and touch up paint finish to avoid rusting. 3. Treat exposed parts with antirust agent, lubricate machine thoroughly and apply grease to unpainted surfaces like lifting and tilting cylinders etc. 4. Fill fuel tank and hydraulic oil tank to "FULL" marks. 5. Cover exhaust pipe (parking outside). 6.
Make sure that coolant is at proper concentration for expected lowest temperatures. 7. Park machine on level, firm ground where there is no risk of freezing, landslide or flooding. Avoid parking machine on a slope. Keep in mind that theft and burglary risk can be minimized by: • Removing starter key when the machine is left unattended. • Locking doors and covers after working hours. • Turning off electrical current with battery disconnect switch. • Park machine where risk of theft, burglary and damage is minimized. • Removing valuables from cabin such as cellular phone, computer, radio and bags. See “Long Term Storage” on page 3-77, for more information.
