PRE-OPERATION 509 & 511 POWER BACKHOE GENERAL INFORMATION The purpose of this manual is to assist in setting up, operating and maintaining your backhoe. Read it carefully. It furnishes information and instructions that will help you achieve years of dependable performance. Right and left, when referred to in this manual, are determined from the operator's control position when facing the backhoe.
PRE-OPERATION NOMENCLATURE Throughout this manual, reference is made to various backhoe components. Study the following diagram to acquaint yourself with the various names of these components. This knowledge will be helpful when reading through this manual or when ordering service parts.
OPERATING INSTRUCTIONS CONTROLS GENERAL INFORMATION Your backhoe is operated by four different control levers. Two are for stabilizer operation 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.
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. Establish a flowing digging cycle to increase operator efficiency and save unnecessary wear on the machine. Observe the following points to obtain the best results and to fully utilize the digging force of the backhoe.
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. The front end loader should also be lowered if the unit is so equipped.
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 damage to the sod and to facilitate replacement.
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.
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 connection. Dig with the backhoe at extreme swing positions, and in as close to the stabilizers as possible. Pile the soil on the opposite side of the trenches. Position the unit forward so the two trenches can be connected. Pile the spoil on the opposite side of the trench.
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. This will allow the backhoe to sit level for digging the main excavation. Pile the spoil from the surface downhill. When digging the main excavation, pile the spoil uphill.
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. If a section of pipe is to be replaced, strip the soil from both ends of the bellhole.
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. Return the bucket to the spoil pile and continue the cycle until the job is completed. IMPORTANT: Do not backfill by using the swing circuit and dragging the bucket sideways.
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. 1. Before transporting the backhoe, raise the boom, dipper, and bucket to the transporting position. 2. Engage the swing lock (if so equipped) by pushing down and to the left on the red swing lock ball handle. 3.
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.
