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.
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 rear 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 servicing, 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 LOADER
1. Read the loader operator’s manual to learn how to operate your loader safely. Failure to do so could result in serious injury or death and equipment damage.
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. Improper use of a loader can cause serious injury or death.
4. Do not lift or carry anybody on the loader or in the bucket or attachment.
5. Never allow anyone to get under the loader bucket or reach through the booms when the bucket is raised.
6. Do not walk or work under a raised loader bucket or attachment unless it is is securely blocked or held in position.
7. Avoid overhead wires and obstacles when loader is raised. Contacting electrical lines can cause electrocution.
8. Make sure all parked loaders on stands are on a hard, level surface.
9. Use a piece of cardboard or wood rather than hands and wear eye protection when searching for hydraulic leaks.
Escaping hydraulic oil under pressure can penetrate skin. If oil is injected into skin, it must be surgically removed
within a few hours by a doctor or gangrene may result.
4
SAFETY PRECAUTIONS CONTINUED
10. Before disconnecting hydraulic lines, relieve all hydraulic pressure.
11. Do not tamper with the relief valve setting. The relief valve is pre-set at the factory. Changing the setting can
cause overloading the loader and tractor and serious operator injury may result.
12. Always wear safety goggles when repairing or servicing machine.
13. When servicing or replacing pins in cylinder ends, buckets, etc., always use a brass drift and hammer. Failure to
do so could result in injury from flying fragments.
14. Replace damaged or illegible safety decals. See decal page for required decals.
15. Do not modify or alter or permit anyone else to modify or alter the loader, any of its components or any loader
function without first consulting your local dealer.
OPERATING THE LOADER
1. It is the loader owner’s responsibility to instruct and have a person read operator’s manual, safety decals and
become familiar with machine controls before allowing them to operate loader.
2. Do not allow children to operate the loader.
3. Before starting or operating the equipment, make a walk around inspection and check for loose or damaged
components. Correct any deficiency before starting.
4. Keep the area of operation clear of all persons, particularly small children. The operator should cease operation
whenever anyone comes within the operating area.
5. Operate the loader from the “Operator’s Seat Only.”
6. Exercise caution when operating the loader with a raised loaded bucket or fork.
7. Avoid loose fill, rocks and holes. They can be dangerous for loader operation or movement.
8. Be extra careful when working on inclines.
9. Allow for the loader length when making turns.
10. Stop the loader arms gradually when lowering or lifting.
11. Use caution when handling loose or shiftable loads.
12. Carry loader arms at a low position during transport.
13. Lower loader arms, stop engine, and lock brakes before leaving the tractor seat.
14. Operate the loader controls only when properly seated at the controls.
15. Do not use loader for handling large, heavy objects such as logs, oil drums, etc.
16. Handling large, heavy objects is dangerous due to:
*Possibility of rolling the tractor over.
*Possibility of upending the tractor.
*Possibility of the object rolling or sliding down the loader arms onto the operator.
17. Use large round hay bale handler attachment with bale retaining devices (grapples, bale spears, clamps, etc.) to
handle large round hay bales. Failure to use retaining devices could allow round hay bales to roll or fall down
loader boom arms onto the operator causing serious injury or death and equipment damage.
