IMPORTANT SAFETY PRECAUTIONS

This symbol is used to call attention to safety 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.

In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel in the operation, transport, maintenance and storage of equipment. Lack of attention to safety can result in accident, personal injury, reduction of efficiency and worst of all—lossof life. Watch for safety hazards and correct deficiencies promptly. Use the following safety precautions as a general guide to safe operations when using this machine. Additional safety precautions are used throughout this manual for specific operating and maintenance procedures. Read this manual and review the safety precautions often until you know the limitations.

THE TRACTOR

1.Read the tractor operator’s manual to learn how to operate your tractor safely. Failure to do so could result in serious injury or death and equipment damage.

2.It is recommended that tractor be equipped with Rollover Protective System (ROPS) and a seat belt be used for all loader operations.

3.Add wheel ballast or front weight for stability.

4.Move wheels to the tractor manufacturer’s widest recommended settings to increase stability.

5.For better stability, use tractor with wide front axle rather than tricycle front wheels.

6.Move and turn the tractor at low speeds.

7.Stop tractor engine, place transmission in park (or neutral), engage parking brake, lower loader arms to ground, cycle all hydraulic controls to relieve pressure, allow machine moving parts to stop, remove ignition key to prevent unauthorized person from starting engine before dismounting tractor or serving, repairing, or making adjustments to the equipment.

8.Wear personal protective equipment (PPE), such as, but not limited to, protection for eyes, ears, lungs, head, hands and feet when operating, servicing, or repairing equipment. Avoid wearing loose clothing or jewelry that may catch and entangle on equipment moving parts.

THE BACKHOE

1.DO NOT operate the backhoe unless it is rigidly attached to the tractor.

2.KNOW your controls. Read this operator’s manual and the manual provided with your tractor. Learn how to stop the tractor, the engine and the backhoe quickly in an emergency.

3.PROVIDE adequate front end weight to counter-balancethe backhoe at all times. 20% of the total tractor, loader and backhoe weight must be on the tractor front axle. If unsure of weight distribution, determine at a weight scale. Total vehicle weight , including backhoe and counter weights, must not exceed the ROPS certificate for gross vehicle weight.

4.BE SURE the area is clear of overhead or underground utilities or other hazards.

5.POSITION a barricade around the work area.

6.KEEP all bystanders a safe distance away.

7.DO NOT attempt to enter operator’s platform of backhoe by using the stabilizers as a step.

8.OPERATE from the backhoe operator’s seat only.

9.ALLOW only one person to operate the backhoe at any time.

10.DISENGAGE safety locks as shown in Figures 1 & 3 before attempting to operate the backhoe.

11. NEVER dig with the backhoe unless the stabilizers are properly set.

4

SAFETY PRECAUTIONS CONTINUED

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.

15.SET BRAKES and block wheels when operating on hills and banks to avoid dangerous runaway.

16.WATCH for overhead wires. DO NOT touch wires with any part of the backhoe.

17.NEVER allow a person to work under a raised bucket.

18.NEVER lift a person with the backhoe.

19.DO NOT use the backhoe as a battering ram. Use the backhoe only for digging.

20.ALWAYS lower the backhoe bucket and stabilizers to the ground, shut off engine, and apply the parking brake before getting off unit, or when not digging.

21.NEVER leave the tractor unattended with the engine running.

22.DO NOT attempt to raise the tractor off the ground or move the tractor forward or backward using the backhoe dipperstick or bucket.

TRANSPORTATION

1.ALWAYS engage safety locks before transporting backhoe. See Figures 1 & 3.

2.DO NOT drive the tractor near the edge of a ditch or excavation.

3.ALWAYS use accessory lights and devices when transporting on a road or highway to warn operators of other vehicles. Check your local government regulations.

4.BE SURE the SMV emblem is visible to the rear.

ADJUSTMENTS AND INSPECTION

1.CHECK pins that attach backhoe to tractor and all pivot pins for tightness several times daily. Replace any parts that are bent, broken or missing.

2.ALWAYS engage safety locks before servicing backhoe. See Figures 1 & 3.

3.DO NOT oil, grease, or adjust the backhoe while it is in motion. For greasing, see Service section for details.

4.DO NOT change any backhoe relief valve settings. They are factory set for best backhoe performance and safety.

5.PROTECT YOUR EYES - WEAR SAFETY GLASSES.

6.GUARD AGAINST INJURY when driving connecting pins or performing any repair in which particles can chip from work piece or striking tool.

7.DO NOT remove any guards on backhoe or tractor.

AVOID HIGH-PRESSUREFLUIDS

ESCAPING fluid under pressure can have sufficient force to penetrate the skin and cause serious injury. Be sure to stop engine and relieve all pressure before disconnecting lines. Be sure all connections are tight and that lines, pipes, and hoses are not damaged before applying pressure to the system. Fluid escaping from a very small hole can be almost invisible. Use a piece of cardboard or wood - not your hands-tosearch for suspected leaks.

SEE A DOCTOR at once if injured by escaping fluid. Serious infection or gangrene can develop if proper medical treatment is not administered immediately.

Make sure everyone is clear of machinery before starting the engine, engaging power, or operating the machine.

EMPLOYEE TRACTOR OPERATING INSTRUCTIONS:

1.Securely fasten your seat belt if the tractor has a ROPS.

2.Where possible, avoid operating the tractor near ditches, embankments, and holes.

3.Reduce speed when turning, crossing slopes, and on rough, slick, or muddy surfaces.

4.Stay off slopes too steep for safe operation.

CAUTION

To avoid the possible injury, observe the following safety rules BEFORE OPERATING 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-balancetractor at all times. 20% of the total tractor, loader and backhoe weight must be on the tractor front axle.

4.Keep bystanders a safe distance away.

DIRECTIONS: The terms right, left, front and back shall be determined from the position of the operator when seated in the operating position on the backhoe.

ENGINE SPEED

The speed at which the backhoe operates is partially dependent on engine RPM. Use a moderate engine speed to start and increase it as your experience permits. Refer to “SPECIFICATIONS” for hydraulic flow volume requirements. When powering from tractor systems with higher output, reduce engine RPM to obtain acceptable backhoe operating speed.

CONTROLS

The backhoe has two major control levers plus the stabilizer control levers. These controls are located on the control panel directly ahead of the operator. See Figure 2. The following is a list of the controls, with the function of each, reading from left to right.

1. Boom/Swing: Push lever forward, the boom moves down, away from the operator. Pull lever back, the boom moves up, toward the operator.

The Boom/Swing Control Lever has an added “float” function. A detent or stop should be felt when the lever is pushed forward to move the boom down. Pushing the lever forward more will overcome the detent and cause the boom to float, or move down or up freely, depending on the forces acting on it. When the lever is released it should return to the center, neutral position.

Move lever to the left, the backhoe swings to the left. Move lever to the right, the backhoe swings to the right.

By moving the lever to one of the intermediate positions, the boom can be swung left or right at the same it is being raised or lowered, performing the two operations simultaneously.

SWING LEFT AND LOWER the boom by moving the control lever forward and to the left.

SWING LEFT AND RAISE the boom by moving the control lever back and to the left.
