IMPORT ANT SAFETY PRECAUTIONS This symbol is used to call attention to safe- ty precautions that should be followed by the operator to avoid accidents. When you see this symbol, carefully read the message that follows and heed its advice. Failure to comply with safety precautions could result in serious bodily injury.
12. DO NOT dig under stabilizers or tractor backhoe. Soft ground or sandy soil can cause cave-ins. 13. KEEP BUCKET away from the stabilizer area to avoid possible stabilizer damage. 14. ALWAYS swing bucket uphill to dump when on a hillside and keep loaded bucket low.
SAFETY DECALS The safety of the operator was a prime consideration in the design of the backhoe. Proper shielding, conve- nient controls, simple adjustments and other safety features have been built into this implement. The following decals are located on the backhoe.
IMPORT ANT FEDERAL LA WS AND REGULA TIONS* CONCERNING EMPLOYERS, EMPLOYEES AND OPERA TIONS. *(This section is intended to explain in broad terms the concept and effect of the following federal laws and regulations. It is not intended as a legal interpretation of the laws and should not be considered as such).
GENERAL OPERA TION CAUTION T o avoid the possible injury , observe the follow- ing safety rules BEFORE OPERA TING the backhoe: 1. BE SURE area is clear of underground utilities or other hazards. 2. POSITION barricade around work area. 3. PROVIDE adequate front end weight to counter-balance tractor at all times.
SWING RIGHT AND LOWER the boom by moving the lever forward and to the right. SWING RIGHT AND RAISE the boom by moving the lever back and to the right. 2. Left Hand Stabilizer: Push lever forward, the LH stabilizer lowers. Pull lever back, the LH stabilizer raises.
Smooth, light handling of the controls will result in the most efficient backhoe operation. Operate the backhoe control levers to become famil- iar with their speed and movements. The engine speed and the size of the hydraulic system will deter- mine the speed of cylinder operation.
CAUTION T o avoid possible injury , observe the following safety rules when transporting the backhoe: 1. AL W A YS engage safety locks as shown on Figs. 1 and 3 when transporting backhoe. 2. TRA VEL SLOWL Y over rough terrain, on hillsides, and around curves to prevent tipping.
General Operations FILLING THE BUCKET Control the bucket attitude throughout the digging cycle to keep teeth at the proper angle for best penetration. This will minimize dragging and scraping the bucket through the ground.
General Operations SIDE SLOPE EXCA V A TING OR TRENCHING Dig with the backhoe uphill whenever possible. Level the backhoe on slopes with the stabilizers to dig plumb trenches, or use the backhoe or loader to cut a level slot for the uphill wheel and stabilizer .
SER VICE CAUTION T o avoid possible injury , observe the following safety rules WHEN SERVICING the backhoe: 1. ENGAGE safety locks as shown in Figures 1 & 3 before servicing the backhoe. 2. DO NOT oil, grease or adjust the backhoe while it is in motion.
T ooth Replacement The bucket tooth points are self-sharpening and will require little attention; however , these points on the bucket shanks can be replaced when they become badly worn or broken. If a tooth shank breaks off, becomes damaged or lost so that it cannot hold a tooth point, a new shank should be welded to the bucket in its place.
REMOV AL FROM TRACTOR - ST ORAGE The backhoe is self-assisting during the installation and removal procedures. For removal and storage, follow these steps: 1. Install the swing safety lock pin as shown in Figures 1 and 3. 2. Stretch out the boom, dipper arm and bucket as shown in Figure 9.
Stabilizer Pads - 765H, 865H and 965H The backhoe is supplied with flip-over stabilizer pads as standard equipment. They are suitable for most backhoe work and generally are all that is ever required. However , street pad kits are available as options for Models 765H, 865H and 965H backhoes.
Causes and Corrections, Continued 12. Bent piston rod in cylinder - replace or rebuild the cylinder; replace damaged parts. 13. Worn or damaged rod seals on cylinder; external leaks - repack cylinder . Rebuild cylinder , replacing damaged parts as necessary .

Tractor Reservoir Note: Do not connect hoses from the backhoe con- trol valve to the tractor hydraulic system until initial assembly of mounting kit is complete.
Hydraulic Hook-Up (865H & 965H) For Tractors With Closed-Center Hydraulic Systems There are two basic types of hydraulic systems, open- center and closed-center. The open-center system con- stantly pumps oil through the hydraulic cylinder operat- ing valves and returns the oil to the reservoir.
