TRACTORS THAT HAVE MOVABLE AXLES MUST BE SET FORWARD IN THE LONG WHEEL- BASE POSITION AS SHOWN IN FIGURE 2-1 TO PREVENT EXCESSIVE LEVERAGE BEING EXERTED ON THE TRACTOR FRAME. FAILURE TO DO SO CAN RESULT IN PERSONAL INJURY AND EQUIPMENT DAMAGE. REFER TO TRAC- TOR OPERATOR’S MANUAL FOR ABOVE PRO- CEDURES AND SPECIFICATIONS FOR YOUR TRACTOR. 2-1 PRE[...]

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. 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 [...]

2-3 DISMOUNTING LOADER CAUTION ALWAYS PARK LOADER WITH MATERI- AL 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. DO NOT STAND, WALK, OR WORK UNDER A RAISED LOADER OR ATTACHMENT U[...]

MAKE SURE PARKED LOADER IS ON A HARD LEVEL SURFACE. ENGAGE ALL SAFETY DEVICES TO PREVENT LOADER FROM FALLING AND BEING DAMAGED OR INJURING SOMEONE. DO NOT REPAIR LOADER IF IT IS NOT MOUNTED ON THE TRACTOR. LOSS OF HYDRAULIC FLUID OR REMOVAL OF PARTS COULD CAUSE LOADER TO COLLAPSE RESULTING IN INJURY. Figure 2-12 Tractor Backed Away From Loader WARN[...]

3-4 EXTERNAL LOADER AND/OR TRAC- TOR VALVE. NOTE When properly installed, the tractor remote valve or external valve control lever/levers will control the loader hydraulic circuits as described below. Refer to tractor Operator’s Manual for further explanation of tractor remote control lever/levers. IMPORTANT Contaminants in hydraulic fluid can ca[...]

IMPORTANT Always keep the cylinders in a retracted position when the loader is not in use to guard against rust and contamination which may cause dam- age to the cylinder rods and hydraulic system. 3-12 REMOVING AIR FROM HYDRAULIC SYSTEM Repeat raising and lowering the loader boom and bucket operations until all the air is removed from the system a[...]

FILLING THE BUCKET Approach and enter the pile with a level bucket. Loaders with 1-lever control, ease lever back and toward you to lift and rollback the bucket. Loaders with 2-lever controls, ease both levers back to lift and rollback the bucket. The lift and rollback of the bucket will increase effi- ciency because... ...a level bucket throughout[...]

CARRYING THE LOAD Position the bucket as low as possible below the level of the tractor hood for maximum stability and visibility, whether the bucket is loaded or empty. Use extreme caution when operating the loader on a slope and keep the bucket as low as possible. This keeps the bucket and tractor center of gravity low and will provide maximum tr[...]

OPERATING WITH FLOAT CONTROL During hard surface operation, keep the bucket level and put the lift control in the float position to permit the bucket to float on the working surface. If hydraulic down pressure is exerted on the bucket, it will wear faster than normal. FLOAT The float will also prevent the mixing of surface material with stockpile m[...]

PEELING AND SCRAPING BACKFILLING 6” Use a slight bucket angle, travel forward, and hold the lift control forward to start the cut. Make a short, angle cut approximately 6” deep and break-out cleanly. With the bucket level, start a cut at the notch approx- imately 2” deep. Hold the depth by feathering the bucket control to adjust the cutting l[...]

Leave dirt in the bucket because dumping on each pass wastes time. Operate at right angles to the ditch. Take as big a bite as the tractor can handle without lugging down. DITCH SOIL PILE Leave dirt which drifts over the side of the bucket for final clean-up. DITCH Pile dirt on the high side for easier backfilling on a slope. HANDLING LARGE HEAVY O[...]
