  • Page 18: Operating Instructions

    OPERATING INSTRUCTIONS CONTROLS GENERAL INFORMATION Your backhoe is operated by four different control levers. Two are for stabilizer opera- tion and the other two operate the swing, boom, dipper, and bucket functions. The information contained below will help you become familiar with the operation of each control lever. Read the Safety Precautions section of this manual before attempting to use the backhoe.

  • Page 19: Before You Start Digging

    OPERATING INSTRUCTIONS OPERATING TECHNIQUES ATTACHMENT TYPE BACKHOES GENERAL INFORMATION When operating the backhoe, smoothness of technique should be strived for at all times. Smoothness will come with experience and practice at feathering the controls. Estab- lish a flowing digging cycle to increase operator efficiency and save unnecessary wear on the machine.

  • Page 20: Before You Start Digging

    OPERATING INSTRUCTIONS OPERATING TECHNIQUES ATTACHMENT TYPE BACKHOES BEFORE YOU START DIGGING (CONTINUED) Once the unit is positioned, lower the stabilizers to the ground. The tires should still be supporting most of the vehicle weight with the stabilizers relieving only part of the weight, and mainly acting to give the unit a wider base for increased stability and to keep the unit from moving or bouncing with backhoe use.
  • Page 21 OPERATING INSTRUCTIONS OPERATING TECHNIQUES ATTACHMENT TYPE BACKHOES BASIC DIGGING TECHNIQUE When starting an excavation, make the first cut of each section shallow, being careful to follow the exact layout of the excavation. The reason for the shallow cut is to minimize dam- age to the sod and to facilitate replacement. These first cuts are also important because they will act as guides for the remaining cuts, thus getting the first few cuts as accurate as possible will help in keeping all future cuts accurate. When digging with the backhoe, extend the boom, dipper and bucket out, away from the operator. Lower the boom and dipper to start the digging process. The bucket teeth should be at a 30° to 45° entry angle. As the digging starts, curl the bucket until the cutting edge is level with the horizon. Crowd the bucket in toward the operator working the bucket lever to keep the bucket level. As the bucket moves toward the operator, manipulate the boom lever to keep the cut level. At the end of the digging cycle, crowd the dipper out and completely curl the bucket while lifting it from the excavation. Once you have cleared the excavation, swing the bucket to the spoil pile. Start to dump the bucket before the pile is approached. Once the bucket is empty, swing the unit back to the excavation, positioning the bucket and dipper for the next cut in the process. The whole digging process should be one smooth cycle that is repeated until the excavation is completed. When the excavation has been dug to within six inches of the finished bottom, clear and touch up the sides of the excavation. Use the flat sides of the bucket to scrape off any high spots. Dislodge any exposed rocks if they seem loose. When finishing walls, finish the far wall by curling the bucket out, crowding the dipper out, and forcing the bucket down. To finish the closest wall, lift the bucket up and curl it in. 6880 1-25-06-2 75475...

  • Page 22: Basic Digging Techniques

    OPERATING INSTRUCTIONS OPERATING TECHNIQUES ATTACHMENT TYPE BACKHOES BASIC DIGGING TECHNIQUES (CONTINUED) Once the sides are cleaned up, finish grading the bottom of the excavation. This is done by making the remaining cuts long and shallow, concentrating on making them level and smooth. Remove any remaining spoil. Check the excavation bottom for depth and levelness, making any adjusting cuts as needed. The basic steps just listed at the same regardless of the excavation. All other digging jobs are simply variations of this basic procedure. Remember to make your cuts in smooth cycles. This will reduce operator fatigue and machine wear while increasing productivity and efficiency. SPECIAL APPLICATIONS TRENCHING BETWEEN A BUILDING AND AN OPEN EXCAVATION Start the trench at the building and trench toward the open excavation. Dig toward the open excavation until there is just enough room to move the unit out from between the trench and open excavation. 6881 1-25-06-2 75475...
  • Page 23 OPERATING INSTRUCTIONS OPERATING TECHNIQUES ATTACHMENT TYPE BACKHOES TRENCHING BETWEEN A BUILDING AND AN OPEN EXCAVATION (CONTINUED) Position the unit so the backhoe swing post is over the center line of the trench con- nection. Dig with the backhoe at extreme swing positions, and in as close to the stabilizers as possible.
  • Page 24 OPERATING INSTRUCTIONS OPERATING TECHNIQUES ATTACHMENT TYPE BACKHOES EXCAVATING ON SLOPES When digging on slopes always face the backhoe upgrade whenever possible. It may be necessary to cut a level surface in the hill for the backhoe to sit in when operating on slopes.
  • Page 25 OPERATING INSTRUCTIONS OPERATING TECHNIQUES ATTACHMENT TYPE BACKHOES PIPELINE LEAK REPAIR To check for pipeline leaks, start by digging a bellhole about six feet wide and ten feet long. Then, dig lengthwise along the pipeline to locate the leak. Once the leak is located, position the unit to dig at grade level on both sides of the pipeline.
  • Page 26 OPERATING INSTRUCTIONS OPERATING TECHNIQUES ATTACHMENT TYPE BACKHOES MISCELLANEOUS - BACKFILLING To backfill an excavation, lower the extended bucket into the spoil pile. Curl the bucket and lift it clear of the spoil pile. Swing the bucket to the excavation and extend the bucket. Re- turn the bucket to the spoil pile and continue the cycle until the job is completed.

  • Page 27: Transporting

    OPERATING INSTRUCTIONS TRANSPORTING GENERAL INFORMATION Follow the simple steps listed below when preparing the backhoe for transportation between work sites. Read and follow the safety precautions for backhoe transporting listed in safety section of this manual before moving the backhoe. Before transporting the backhoe, raise the boom, dipper, and bucket to the transporting position.

  • Page 28: Lubrication

    LUBRICATION 509 & 511 BACKHOE GENERAL INFORMATION Economical and efficient operation of any machine is dependent upon regular and proper lubrication of all moving parts with a quality lubricant. Neglect leads to reduced effi- ciency, heavy draft, wear, breakdown, and needless replacement parts. All parts provided with grease fittings should be lubricated as indicated. If any grease fittings are missing, replace them immediately. Clean all fittings thoroughly before using grease gun. IMPORTANT: Avoid excessive greasing. Dirt collects on exposed grease and greatly increases wear. After greasing, wipe off excessive grease from fittings. LUBRICATION SYMBOLS The following symbol is used on the lubrication diagram printed on the following page. It is reproduced here with its meaning for your convenience. Lubricate daily or every 8 hours of operation, whichever comes first, with SAE Multi-Purpose Lubricant or an equivalent SAE Multi Purpose type grease. CAUTION! Shut off vehicle engine before lubricating equipment.
  • Page 29 LUBRICATION 509 & 511 BACKHOE BACKHOE LUBRICATION DIAGRAM The following diagram is provided to help you locate all the points on your backhoe that need lubricating. Be sure to follow the lubrication intervals as noted by the lubrication symbols used on this page. Always replace any missing grease fittings as soon as possible.
