SECTION II LOADER MOUNTING AND DISMOUNTING 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.
USE CAUTI ON WHEN MOUNTING LOADERS EQUIPPED WITH OPTIONAL CONTROL VALVE ON TRACTORS EQUIPPED WITH CANOPY. RAISING LOADER SUBFRAME TOO HIGH CAN PINCH HAND BETWEEN CONTROL HANDLE AND CA NOPY CAUSING INJURY. WARNING D. With tractor at idle speed, carefully activate boom cylinders to raise/lower cross tube until it aligns with front bracket channel.
Figure 2-6 J. Secure hydraulic hoses to tractor to prevent interference. It is recommended that hoses be rout- ed under tractor operator’s platform. K. Exte nd and retract both sets of cylinders beginning with short strokes. Gradually increase the length of stroke until cylinders “bottom out” in each direction.
C. Lower boom until parking stands contact ground. D. Extend bucket cylinders until cutting edge of bucket is frimly on the ground. E. Remove pin from mounting bracket. G. With tractor at idle speed, roll bucket back until subframe raises up off rear bracket.
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.
CARRYING THE LOAD Position the bucket as low as possible below the level of the tractor hood for maximum stability a nd 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.
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.

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.
