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.
SAFETY PRECAUTIONS CONTINUED 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. 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.

SECTION II LOADER MOUNTING AND DISMOUNTING 2-1 PREPARING TRACTOR CAUTION TRACTORS THAT HAVE MOVABLE AXLES MUST BE SET FORWARD IN THE LONG WHEELBASE 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 TRACTOR OPERATOR’S MANUAL FOR ABOVE PROCEDURES AND SPECIFICATIONS FOR YOUR TRACTOR. Figure 2-1 A. Check air pressure in tractor tires to be sure it is adequate for heavy loads. B.
Figure 2-4 Cuff Arrangement WARNING USE CAUTION 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 CANOPY CAUSING INJURY. Pivot Pin D. With tractor at idle speed, carefully activate boom cylinders to raise/lower cross tube until it aligns with front bracket channel. E. Drive tractor forward until cross tube fully engages front bracket channel and install front bracket pin.
Figure 2-6 Cylinder Mounting Bushing ing bushing in relation to the subframe. (Figure 2-6) Remember this position to aid in aligning cross tube with front bracket when loader is being mounted to tractor. B. Remove parking stands from storage. Raise boom and install as shown in Figure 2-7. 2-3 DISMOUNTING LOADER Dismount loader on firm, level ground to facilitate the next mounting. It is recommended that loader be stored in a dry place to prevent rusting.
Figure 2-8 Loader Dismounted subframe raises up off rear bracket. H. With tractor at idle speed, carefully activate boom cylinder until cross tube is free of pressure within front bracket channel. It may be necessary to roll bucket back further to maintain sufficient clearance between subframe and rear cross tube. I. Disconnect hydraulic hoses from tractor quick disconnect couplers. J. Carefully back tractor out of loader. (Figure 2-8) K.
...a level bucket throughout the lifting cycle resists bucket lift and increases breakaway effort. FILLING THE BUCKET Approach and enter the pile with a level bucket. NOTE; Do not be concerned if the bucket is not completely filled during each pass. Maximum productivity is determined by the amount of material loaded in a given period of time. Time is lost if two or more attempts are made to fill the bucket on each pass.
CARRYING THE LOAD DUMPING THE BUCKET 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. Lift the bucket high enough to clear the side of the vehicle. Move the tractor in as close to the side of the vehicle as possible, then dump the bucket. 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. FLOAT Sidecutting is a good technique for cutting down a big pile. The float will also prevent the mixing of surface material with stockpile material.
PEELING AND SCRAPING BACKFILLING 6” Backgrade occasionally with a loaded bucket to keep the working surface free of ruts and holes. Hold the lift control forward in float position so the full weight of the bucket is scraping the ground. Use only the heel of the bucket while backgrading. 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.
HANDLING LARGE HEAVY OBJECTS WARNING Do not use front end loaders for handling large heavy objects such as logs or oil drums. Handle large round hay bales only when loader is equipped with Bush Hog Bale Spear Attachment. Handling large heavy objects can be extremely dangerous due to: Leave dirt in the bucket because dumping on each pass wastes time. H Possibility of rolling the tractor over. H Possibility of upending the tractor.
3-4 FORK LIFT OPERATION 3-5 QUICK HITCH OPERATION WARNING The quick hitch (Figure 3-4) is designed to allow easy mounting and dismounting of attachments from loader. With attachment on flat, level surface, mount as follows: TO AVOID SERIOUS INJURY OR DEATH: H NEVER LIFT LARGE ROUND HAY BALES OR OTHER LOADS ON THE FORK LIFT ATTACHMENT THAT COULD ROLL BACK ONTO TRACTOR OPERATOR AREA. H NEVER USE FORK LIFT ATTACHMENT TO LIFT OR SUPPORT PEOPLE. H TRANSPORT LOADS LOW AND SLOW.
SECTION IV MAINTENANCE 4-1 MAINTENANCE CHECK LIST 4-2 LUBRICATION (Figure 4-1) Perform scheduled maintenance as outlined below. Lower machine to ground, turn off tractor, and set parking brake before doing maintenance inspections or work. All bolts should be torqued as recommended in torque chart unless otherwise indicated. NOTE The multi-purpose grease referenced in this section is an NLGI grade 2 type grease. BEFORE EACH USE 1.
