FAILURE TO DO SO CAN RESULT IN PERSONAL INJURY AND EQUIPMENT DAMAGE. REFER TO TRACTOR OPERATOR’S MANUAL FOR ABOVE PROCEDURES AND SPECIFICATIONS FOR YOUR TRACTOR. A. Check air pressure in tractor tires to be sure it is adequate for heavy loads. B. Add rear wheel weights, fluid in tires, or equivalent to provide sufficient tractor stability. C. It is recommended that tractor wheels be moved to the widest settings. D. Check tractor hydraulic oil reservoir to be sure it is full. E. Refer to your tractor operator’s manual for above procedures and specifications for your tractor. 2-2 MOUNTING LOADER To aid in mounting and dismounting loader, apply a small amount of grease, if needed, to each loader bracket in area of top receiver and guide. Figure 2-2. A. Slowly drive tractor to a position where the hoses can be connected to the quick couplers. Stop the engine. Connect the loader hydraulic hoses to the correct couplers. Figure 2-3. B. Retract Loader Lift Cylinders. Figure 2-3. Figure 2-1 Short Wheelbase Long Wheelbase Figure 2-2 Apply Grease To These Areas Figure 2-3 Drive In Close Enough To Alllow Connecting Hydraulic Hoses To Tractor Outlets 10 C. Check that lift cylinders are fully retracted. Figure 2-3. Then drive tractor forward. Use bucket cylinders to position height of outer pedestal top pin. Figure 2-4. Figure 2-4 Outer Pedestal Top Pin D. Align outer pedestal top pin with mounting bracket guide post on both sides. Make sure loader is centered right to left on both brackets. E. Extend the bucket cylinders to lower the pedestal top pins into mounting bracket receivers on both sides. F. Extend lift cylinders slowly making sure loader is seated completely in mounting bracket top and bottom receivers. Retract bucket cylinder until bucket is approximately 1/2” off ground. G. Slide quick pin into position and let pin handle extend downward through the retaining loop at the bottom of the subframe. Figures 2-5 and 2-6 Figure 2-5 Quick Pin Figure 2-6 Pin In Operating Position H. Remove parking stands from the parked position and return them to their storage positions in the cross tube. Figure 2-7 Figure 2-7 Storing Parking Stand Secure parking stands in the storage position by using the provided pins. Figure 2-8 Figure 2-8 Parking Stand Stored I. Lower loader to ground and secure loader hydraulic hoses in a protected area. IMPORTANT To avoid hydraulic hose damage, be alert and make sure hoses do not catch on tractor and/or loader during mounting or dismounting. 11 2-3 DISMOUNTING LOADER CAUTION ALWAYS PARK LOADER WITH MATERIAL BUCKET OR AUTHORIZED BUSH HOG ATTACHMENT ATTACHED TO THE LOADER. CAUTION BEFORE LEAVING THE TRACTOR SEAT, LOWER ATTACHMENT OR LOADER BOOM TO GROUND, STOP ENGINE, LOCK BRAKES, RELIEVE HYDRAULIC PRESSURE, AND REMOVE KEY. CAUTION DO NOT STAND, WALK, OR WORK UNDER A RAISED LOADER OR ATTACHMENT UNLESS IT IS SECURELY BLOCKED OR HELD IN POSITION. ACCIDENTAL MOVEMENT OF A CONTROL LEVER/LEVERS OR LEAKS IN THE HYDRAULIC SYSTEM COULD CAUSE THE LOADER TO DROP, OR ATTACHMENT TO DUMP, CAUSING SEVERE INJURY. CAUTION DO NOT ALLOW BYSTANDERS IN LOADER AREA. IMPORTANT Never allow weight of tractor to be placed on parking stands when mounting or dismounting loader. A. Position the loader on a hard level surface. The more level the surface, the easier the loader is to mount and dismount. B. Raise loader, dump bucket over, and then lower loader so that bucket cutting edge is approximately 1/2” off of surface. C. Remove parking stands from their storage positions in the boom crosstube as shown in Figure 2-8. D. Position parking stands in attaching brackets on inside of each loader arm and secure. Figure 2-9. E. Dismounting procedures will be the reverse of the mounting procedure. F. Rollback bucket slightly while lowering loader boom down until the parking stands make firm contact with ground. Dump bucket until bucket touches the surface. NOTE Driving the tractor forward slowly while position ing loader will allow parking stands to contact ground firmly. Figure 2-9 Parking Stand Installed Attaching Bracket Long End Positioned Rearward G. Retract loader lift cylinders H. Slowly rollback bucket while driving slightly forward with tractor. Doing this will allow...
