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—loss of 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.

1.

Read the Operator’s Manual. Failure to read the Operator’s Manual is considered a misuse of this equipment.

2.

Become familiar with all the machine’s controls and all the caution, warning and danger decals affixed to the machine before attempting to start or operate.

3.

Before starting or operating the machine, make a walk around inspection and check for obvious defects such as loose mounting bolts and damaged components. Correct any deficiency before starting.

4.

Do not allow children to operate the implement. Do not allow adults to operate it without proper instruction.

5.

Do not carry passengers.

6.

Keep the area of operation clear of all persons, particularly small children and pets. The operator should cease operation whenever anyone comes within the operating area.

7.

Use a piece of cardboard or wood rather than hands to search for hydraulic leaks. Escaping hydraulic oil under pressure can penetrate skin. If fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

8.

Lower implement to ground, stop tractor engine and apply parking brake before leaving the tractor.

9.

Keep hands and feet away from cutting edge.

10.

Wear personal protective equipment such as, but not limited to, protection for eyes, ears, feet, hands and head when operating or repairing the equipment. Do not wear loose clothing or jewelry that may catch on equipment moving parts.

11.

When performing adjustments or maintenance on the blade, first lower it to the ground or block it securely at a workable height.

12.

Never stand between tractor and implement while tractor is being backed to the hitch.

13.

Reduce speed when transporting implement to avoid bouncing and momentary loss of steering.

14.

Use tractor flashing warning lights, day or night, when transporting cutter on road or highways unless prohibited by law.

15.

It is recommended that tractor be equipped with Rollover Protective System (ROPS) and seat belt be used in all implement operations.

IMPORTANT FEDERAL LAWS AND REGULATIONS* CONCERNING

EMPLOYERS, EMPLOYEES AND OPERATIONS.

*(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).

U.S. Public Law 91-596 (The Williams-Steiger Occupational and Health Act of 1970) OSHA

This Act Seeks:

“...to assure so far as possible every working man and woman in the nation safe and healthful working conditions and to preserve our human resources...”

DUTIES

Sec. 5 (a) Each employer—

(1) shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees;

(2) shall comply with occupational safety and health standards promulgated under this Act.

(b) Each employee shall comply with occupational safety and health standards and all rules, regulations and orders issued pursuant to this Act which are applicable to his own actions and conduct.

OSHA Regulations

Current OSHA regulations state in part: “At the time of initial assignment and at least annually thereafter, the employer shall instruct every employee in the safe operation and servicing of all equipment with which the employee is, or will be involved.” These will include (but are not limited to) instructions to:

Keep all guards in place when the machine is in operation;

Permit no riders on equipment;

Stop engine, disconnect the power source, and wait for all machine movement to stop before servicing, adjusting, cleaning or unclogging the equipment, except where the machine must be running to be properly serviced or maintained, in which case the employer shall instruct employees as to all steps and procedures which are necessary to safely service or maintain the equipment.

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.

5. Watch where you are going, especially at row ends, on roads, and around trees.

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

6. Do not permit others to ride.

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

7. Operate the tractor smoothly - no jerky turns, starts, or stops.

4. Stay off slopes too steep for safe operation.

8. Hitch only to the drawbar and hitch points recommended by tractor manufacturers.

9. When tractor is stopped, set brakes securely and use park lock if available.

Child Labor Under 16 Years Old

Some regulations specify that no one under the age of 16 may operate power machinery. It is your responsibility to know what these regulations are in your own area or situation. (Refer to U.S. Dept. of

Labor, Employment Standard Administration, Wage & Home Division, Child Labor Bulletin #102.)

Place the tractor rockshaft control in “position control” (non-floating) for attaching and detaching the rear mounted blade. “Draft control” or “position control” can be used while operating.

Back the tractor until the ends of the lift arms can be attached to the lift pins on the implement. Secure the lift arms to the mast. (Figure 1)

Attach the center link to the top of the mast and adjust so that the blade will be level in the operating position

DETACHING FROM TRACTOR

Lower the blade to the ground with rockshaft control in position control. Remove top link from mast, disconnect lift arms from bottom pins and pull tractor away from blade.

6

CAUTION

WHEN DETACHING THE BLADE, SUPPORT

THE MAST END OF THE BOOM TO PRE-

VENT IT FROM FALLING. KEEP BODY,

HANDS AND FEET CLEAR OF IMPLEMENT.

FIELD ADJUSTMENTS

The ditching angle of the blade can be controlled by adjusting the tractor lift arms. Shorten or lengthen the link between the rockshaft and the lift arm to cause one end of the blade to be higher or lower than the opposite end. On most tractors, the blade can be tilted 9 degrees right or left.

To change the operating angle, remove the index pin and move the blade to the desired position, either facing forward or swiveled to the rear for back blading. Replace the index pin and secure with hair pin clip.

Care should be exercised during use of the blade to prevent hanging the ends on immovable objects or otherwise using the implement under conditions beyond its designed capacity.

CAUTION

WHEN EQUIPMENT IS TRANSPORTED, USE

NECESSARY DEVICES REQUIRED BY LOCAL

REGULATIONS FOR ADEQUATE WARNING

TO OPERATORS OF OTHER VEHICLES.

ADDITIONAL TRACTOR FRONT BALLAST

MAY BE REQUIRED FOR STABLE OPERA-

TION AND TRANSPORT OF IMPLEMENT. SEE

TRACTOR OPERATOR’S MANUAL FOR REC-

OMMENDED WEIGHTS. IT IS RECOMMENDED

THAT TRACTOR BE EQUIPPED WITH

ROLLOVER PROTECTIVE SYSTEM (ROPS).

SECTION II

CRB SERIES ASSEMBLY

Assemble the hitch frame to the moldboard by sliding the king pin up through the “A” frame boom; install flat washer and fasten with a 1-1/4” lock nut.

Do not over-tighten so as to prevent the moldboard from pivoting.

Lock the moldboard into the desired position with the angle adjusting index pin. Insert hair pin through bottom of the adjusting pin.

SECTION III

MAINTENANCE

Periodically check the hitch pins and insure that the hex nuts are tight.

Check lock nut on king pin to insure that it is snug, but still allows the moldboard to pivot.

Store the blade out of the weather when it is not in use. This prevents rusting of the moldboard and other components.

Inspect your blade periodically and replace any worn or broken parts in order to have your implement ready for use when needed.
