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, fork, or large round hay bale handling 
attachments.

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.
