OPERATION WARNING: Never allow anyone to operate the backhoe until they have carefully reviewed and understood this owners manual. GENERAL INFORMATION: Throughout this manual, reference is made to various backhoe components. The purpose of this page is to acquaint you with the various names of these components. This knowledge will be helpful when reading through this manual or when ordering service parts. - Page 10 OPERATION GENERAL INFORMATION Your backhoe is operated by four different control levers. Two are for stabilizers 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 precations of this manual before attempting to use the backhoe.
- Page 11 OPERATING INSTRUCTIONS 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.
- Page 12 OPERATING INSTRUCTIONS 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 13 OPERATING INSTRUCTIONS 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 shallow cut is to minimize damage to the sod and to facilitate replacement.
- Page 14 OPERATING INSTRUCTIONS 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 in level for digging the main excavation.
- Page 15 OPERATING INSTRUCTIONS TRANSPORTING Follow the simple steps listed below when preparing the backhoe for transporting between work sites. Before transporting the backhoe, raise the boom, dipper, and bucket to transporting position. Engage the boom lock to lock the boom to the swing post in the transporting position. Replace lock pins to secure boom lock.
- Page 16 OPERATING INSTRUCTIONS Pre-Operation Check List (Owner’s Responsibility) The operator should perform the following check list before operating backhoe. • Check that backhoe is properly and securely attached to tractor. • Make sure all hydraulic connections are tight and all hydraulic lines and hoses are in good conditions before engaging tractor PTO.
