IMPORTANT SAFETY PRECAUTIONS

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 mower. 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 mowing whenever anyone comes within the operating area.

7. Clear the work area of objects which might be picked up and thrown.

8. 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.

9. Do not operate without all guards and shields in place and in good condition.

10. Stop PTO, lower implement to ground, place tractor transmission in neutral or park, set parking brake, stop tractor engine, remove ignition key and wait for all motion to completely stop before leaving the tractor.

11. Keep hands and feet away from blades.

12. This mower is not to be operated in any area where people may be present unless all sides of the unit are enclosed by a curtain guard that is in good repair.

13. 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.

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

15. Never stand between tractor and mower while tractor is being backed to the cutter hitch.

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

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

18. Pin transport lock to retain cutter bar in transport position.

19. Lower mower to ground before unhitching from tractor.

20. In the event that someone other than yourself will operate this equipment we firmly suggest that all SAFETY references be discussed prior to operation.

21. It is recommended that tractor be equipped with Rollover Protective System (ROPS) enclosed cab, and a seat belt.

Generally about supplementary equipment:

Machines are from the factory available with several options. See your Bush Hog dealer for more information on these options. This supplementary equipment and other extra equipment are mentioned on page 35.

Fitting to the tractor

The tractor must be of a suitable size, adhere to the local laws. Please note that side-mounted

machines affect the stability of the tractor when driving in hilly conditions.

Couple the machine to the three-point suspension of the tractor. The tractor must have stabilizing chains on the lifting arms of the three-point suspension.

IMPORTANT

To achieve a good ground clearance under the machine when it is lifted in the three-point-suspension of the tractor the lifting arms must be able to be raised at least 950 mm (37-1/2”) above the ground. Otherwise, the stated ground clearances, shown on page 25 , will be smaller. This especially applies to the wide machines model HM2008 and HM2009.

We reserve the right to make alterations without notice. We also make reservations as to the possible misprints in the manual.

Machine Identification

The machine serial number and manufacturer information can be found on the metal plate, as shown.

③

Any operator, repairer and owner must be familiar with the warning instructions for the machine in this manual, before operations commence.

Always work carefully with agricultural machinery. Read through and observe the safety instructions in this manual. Safety is your responsibility.

Pay particular attention to this symbol. It means that there could be a serious hazard. It emphasizes precautions which have to be complied with in order to prevent accidents.

This symbol can be found throughout this manual and on the warning signs on the machine. They are for your safety and should be observed at all times.

General Safety Instructions

Be careful when other people or animals are close by! Never start up the machine when people or animals are close or on the machine or tractor. Never stand between the tractor wheels and the machine.

Adhere to the local laws regarding children’s minimum working age with agricultural machinery.

Use of the machine. The machine must only be used for harvest of common grass and grain crops. The machine must not be used for harvest of maize, lawn mowing in parks and cutting of hedges, neither in vertical or in horizontal position.

④

⑤

⑥

⑦

Use personal protection devices. Do not wear loose clothing which may catch in any of the moving parts. In dusty conditions a suitable mask must be used.

Take care of excessive sound level. Certain tractor/implement combinations, dependent on operating conditions, may generate a noise level in excess of 85 dB at the operators ear, even in a quiet cab. In these circumstances ear protection must be worn. Keep cab windows and doors CLOSED at all times to reduce noise level.

The machine must only be coupled to a correctly sized tractor, and no other machines or implements must be coupled. The weight of the tractor must correspond to the machine.

Observe all local laws. Be careful that the tractor is not unbalanced when coupling. Make sure that the tractor has the correct PTO. A machine intended for 540 rpm PTO input

speed must never be coupled to a tractor with 1000 rpm PTO output speed.

Coupling of tractor and machine must be carried out as explained in the instructions. All lock pins must have locking retainers. Observe all local laws regarding road transport.

Work in a safe way. The tractor engine must ALWAYS be stopped and the ignition key removed before carrying out repairs, cleaning, lubricating or maintaining the machine.

①

Safety guards. Make sure that ALL GUARDS are in good order and fitted correctly. Do no attempt to start the machine before ensuring this.

Pay particular attention to the plastic guards of the PTO shaft. If damaged they must be replaced. The chain locks of the guards MUST always be fitted on a suitable place on the tractor

and the machine to prevent the outer plastic guards turning.

②

③

④

Hydraulics. Be very careful when dealing with hydraulics. Use eye protection and gloves. Escaping hydraulic oil under pressure might penetrate into the skin and cause serious infection. See a doctor if you have been exposed to injury.

Be watchful - damaged hydraulic hoses must be replaced immediately. Never use sealing tape or similar to repair the hoses. The hoses must be securely fixed. All hydraulic hoses of the

machine should be replaced at least every 4 years.

Remember when uncoupling, and when leaving tractor/machine. The machine must be in the

working position when uncoupling from the tractor. All hydraulic functions must be in neutral position, the machine must be lowered to the ground and be safely secured. Never allow children to play or be near agricultural machinery.

Drive safely. Be aware of your responsibility - carelessness or slovenliness can cause serious injury or death.

Before transporting on public roads, - always check that the machine is locked with cotter bolt and stop valve, that the coupling is in order, and that possible hydraulic systems and pawls are locked, see the manual of the machine.

Drive carefully. Reduce speed when turning and driving on uneven ground - take care that tractor/machine is not swinging and becoming unstable.

⑤

⑥

⑦

⑧

Please note that there is danger of overturning when working on slopes and in soft ground conditions.

The machine must not be used in situations that unbalances the tractor.

Lighting. It is the responsibility of the owner/operator to provide correct lights and reflectors on the machine, when it is being transported on public roads after dark. Observe the local laws.

Safety equipment. Always carry first aid equipment on the tractor. Also observe local laws concerning fire extinguishers. When working with hay or straw a fire extinguisher must be available at all times.

Spare parts. For safety reasons use only original spare parts. If injury occurs when using nonoriginal spare parts the Bush Hog warranty is invalidated.

Maintenance. Take care that the machine is properly maintained and kept in good safe working condition. Never change the technical construction of the machine.

New Machine - be careful

①

②

③

④

Read the directions for use. Great care must be taken, when starting up a new machine. Incorrect mounting, wrong operations, etc., can result in expensive repairs and loss of profits. Bush Hog’s factory warranty is voided if the instructions of this manual are not adhered to.

NOTICE

Be especially attentive to the following when starting a new machine.

Check that the machine is mounted correctly, and that it is not damaged. Machines with hydraulic stabilizer: Be certain that the hydraulic hoses are mounted so that they are long enough to allow for cylinder movements.

Be very careful when the machine is coupled to the tractor. If the coupling has not been carried out as explained in this manual the machine will not work correctly. Please note that the working height (A) is adjusted correctly. See page 24.

Be very careful when fitting the PTO shaft. If the PTO shaft is too short or too long it can cause great damage to the machine and tractor. Overriding clutch must be fitted on the shaft end of the machine. See pages 22 & 23.

If the PTO shafts of the machine are noisy or vibrating the fitting instructions must be repeated. See pages 22 & 23.

⑤

⑥

⑦

It is very important to check the area of motion of the stabilizer. If the adjustment has not been carried out as explained in this manual the machine will not work correctly. See page 24.

Before starting up a new machine it must be lubricated. Check that gearbox and cutterbar are filled with oil and that the oil level is correct. Use only the oil grades prescribed in the manual.

Check that all bolts at cutting discs and knives are tightened before the machine is started.

Check and re-tighten all bolts on the machine after the first hour of operation. This is especially important for quickly rotating parts. Also re-tighten after service work has been carried out.
