Page 67: Transportation And Storage
4.TRANSPORTATION AND STORAGE 4.1 GENERAL TRANSPORTATION RULES  Before using trailer to transport machine, contact local traffic department to confirm relevant regulations, make sure that machine’s overall length, width, height and weight are within allowed spec.  If there are any dimensions out of spec, obtain special permission from relevant government agencies or dismantle the machine into smaller unit to transport.
Page 68: Transport On Highway
4.3 TRANSPORT ON HIGHWAY Before transportation on highway (As figure 4.1.2), you should know and follow all the related regulations. A. Check the length, width, height, and weight of the trailer that loads excavator. B. Check transportation route conditions, such as dimension and weight limitations and traffic rules.
Page 69: Load And Unload
4.4 LOAD AND UNLOAD 1. The machine should travel at lowest speed on slope. 2. To avoid turning when move on slope, if need turning, the machine should return to the ground or trailer bed, modify the travel direction, then pass the slope. 3.
Page 70: Storage
Tie the chain or thick rope on the chassis frame, don’t traverse or press the chain or thick rope on the hydraulic pipe or hose. Transportation  Place chocks at the front and rear of crawler to fasten machine.  Fasten the 4 corners and foreside attachment of machine on the Figure 4.1.7 trailer with chain or thick rope (As figure 4.1.7).

Machine handling before storage Grease the parts that need lubrication until fresh grease runs out. Change engine oil. Grease the exposed surface of piston rod. Fill in diesel oil to the fuel oil tank to the full.
Page 72: Maintenance
5.1.1 Correct Maintenance and Inspection Procedure 【Important】  Use recommended fuel, hydraulic oil, and lubricant.  Only use original SUNWARD parts.  If user doesn’t use recommended fuel, hydraulic oil, lubricant, and original SUNWARD parts, the warranty is automatically invalid.
Page 73: Checking Excavator Before Daily Starting
 Never adjust engine rev limiter or hydraulic system safety valve.  Avoid electric parts touching with water and vapour.  Never disassemble engine pump controller, sensor, etc. 5.1.2 Checking Excavator Before Daily Starting Check excavator before daily operation.  Check monitor.
Page 74: Using Fuel And Lubricant Correctly
【Important】 Always use recommended fuel and lubricant, otherwise it will damage the machine and lose the warranty of Sunward. 5.1.6 Checking Discharged Grease And Used Filter Core  With oil or filter core replaced, check used oil and filter core for any metal chips and debris. If a large amount of metal chips or debris are found, report to the owner of the machine or your superior, and take proper measures.
Page 75: Hydraulic System Maintenance
Service relating to the electric system is checking fan belt tension, checking damage or wear to the fan belt and checking battery fluid level.  Never install any electric elements other than those specified by SUNWARD.  When working at seashore, carefully clean the electric system to prevent corrosion.
Page 76: Oil, Coolant And Filter
 The hydraulic system has been filled with SAE 10W CD oil, when the machine is shipped from factory  Do not use any hydraulic oil other than those recommended by SUNWARD. Failure to do so may cause filter clogging.
Page 77: Coolant In Cooling System
-15° C（5° F）. it’s necessary to use the fuel that is suitable from the temperature.  To prevent humidity in air to condense in fuel tank to form water, top up oil tank after the work is finished everyday.  Before starting the engine, or when 10 minutes have passed after adding fuel, drain the sediment and water from the fuel tank.
Page 78: Filter
 When replacing filters, check if any metal particles are affixed to the old filter. If any metal particles are found, contact your SUNWARD distributor. Do not open packs of spare filters until just before they are to be used. Always use SUNWARD genuine filters.
