SAFETY SECTION Safety Section 1-1
SAFETY General Safety Instructions and Practices SAFETY A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and observing certain precautions. The first section of this manual includes a list of Safety Messages that, if followed, will help protect the operator and bystanders from injury or death.
SAFETY Never allow children to operate, ride on, or come close to the Tractor or Implement. Usually, 16-17 year-old children who are mature and responsible can operate the implement with adult supervision, if they have read and understand the Operator’s Manuals, been trained in proper operation of the tractor and Implement, and are physically large enough to reach and operate the controls easily. (SG-11) Never allow children or other persons to ride on the Tractor or Implement.
SAFETY Operator Safety Instructions and Practices Never operate the Tractor or Implement until you have read and completely understand this Manual, the Tractor Operator’s Manual, and each of the Safety Messages found in the Manual or on the Tractor and Implement. Learn how to stop the tractor engine suddenly in an emergency. Never allow inexperienced or untrained personnel to operate the Tractor or Implement without supervision.
SAFETY Prolonged operation may cause operator boredom and fatigue affecting safe operation. Take scheduled work breaks to help prevent these potentially impaired operating conditions. Never operate the Implement and Tractor in a fatigued or bored mental state which impairs proper and safe operation. (SG-32) Use extreme caution when getting onto the Implement to perform repairs, maintenance and when removing accumulated material. Only stand on solid flat surfaces to ensure good footing.
SAFETY The Boom is designed only to position and operate the Bucket which is attached to it. Never attempt to lift, pull, or push other solid objects with the boom or bucket. Serious injury could result from a structural failure when the Boom is used for purposes other than those for which it was designed.
SAFETY Keep bystanders 10 feet away from the tractor and loader while operating. The bystanders could enter the path of the tractor or items could fall from the loader resulting in serious injury to the bystander. (SL-01) Before dismounting the tractor and loader lower the loader to the ground or onto solid support blocks. Engage the loader valve travel lock to prevent inadvertent movement of the valve controls causing the loader to suddenly move and drop.
SAFETY Only mount the loader on a tractor that is listed on the mounting instructions. Never mount on a tricycle steering front axle. Move the tractor front and rear wheels to the widest spacing and add the recommended rear tractor ballast to prevent tractor tip over. Keep the tractor tires properly inflated. Maintain at least 25% of the total Tractor and Loader weight including the maximum load in the bucket or attachment on the rear axle.
SAFETY Use extreme care when loading, transporting or dumping loads that impair or partially block the operator’s line of sight. Know where you are traveling. Make sure no bystanders are in the area of travel. If a bystander assists in providing guidance, make sure they are not in the path of travel. Keep all bystanders 25 feet away from travel path. (SL-29) Always look behind you before backing up. Make sure you are looking in the direction of travel. A bystander could walk behind the tractor.
SAFETY The center of gravity of a Power Unit equipped with a front-mounted Implement is shifted to the front and removes weight from the rear wheels. The Power Unit should maintain at least 25% total weight with the maximum load in the bucket or attachment on the rear wheels to prevent tipping forward, loss of steering control, and possible injury. Add counterweight if required when operating on slopes and proceed with the load uphill to prevent tipping.
SAFETY Connecting or Disconnecting Implement Safety Instructions and Practices Do not stand or allow bystander or coworkers between the loader and the tractor while installing or disconnecting the loader from the tractor. Keep hands and body clear of the loader and the loader mounts. Serious injury or death can result from a person being crushed between the tractor and loader. (SL-03) Make sure the loader is properly attached to the tractor and the retaining pins securely lock the loader into position.
SAFETY Transporting Safety Instructions and Practices Transport only at speeds where you can maintain control of the equipment. Serious accidents and injuries can result from operating this equipment at high speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly.
SAFETY Lower the loader to the bed of the truck or trailer when transporting the tractor and loader with a truck. Measure to ensure the transport height does not exceed the legal limits. Contact with overhead obstructions or power lines can cause property damage or serious injury. (SL-34) In case of mechanical difficulty during operation, place the transmission in the park position, set the parking brake, shut down all power, including the PTO and the engine and remove the key.
SAFETY Never work under the Implement, the framework, or any lifted component unless the Implement is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or even death. (SL-36) SAFETY Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and fuel are explosive and their presence could present a hazard.
SAFETY Avoid contact with hot surfaces of the engine or muffler. Use gloves and eye protection when servicing hot components. Contact with a hot surface or fluid can cause serious injury from burns or scalding. (SG-38) Never allow anyone to get under the loader or attachment or to reach through the loader lift arms when raised. Serious injury could result from crushing or pinching by the loader or attachment.

OPERATION OPERATION This Implement may be wider than the Tractor. Be careful when operating or transporting this equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete abutments or other solid objects. Such an impact could cause the Implement and Tractor to pivot violently resulting in loss of steering control, serious injury, or even death. Never allow the Implement to contact obstacles.
OPERATION Use extra care when turning or stopping. Allow for increased length and weight of added loader. The loader adds five to six feet of length in front of the tractor and significant weight. Allow extra distance when stopping or turning. Do not allow loader or attachment to contact solid objects. (SL-07) 6.2 Driving the Tractor and Loader Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the tractor and loader.
OPERATION Do not raise the loader on a hillside. Do not transport across a slope with a raised loader. When the loader is raised, the center of gravity of the tractor and loader is raised increasing the potential for the tractor to tip over. Tractor wheel contact with any wash out, drop off or the ground obstruction with a raised loader could result in the tractor tipping over and causing serious bodily injury.
OPERATION Use extra care when turning or stopping. Allow for increased length and weight of added loader. The loader adds five to six feet of length in front of the tractor and significant weight. Allow extra distance when stopping or turning. Do not allow loader or attachment to contact solid objects. (SL-07) Do not raise the loader into an overhead structure or allow a raised attachment to contact overhead structures. Sudden or unexpected contact with an overhead structure could result in serious injury.
OPERATION OPERATION Know before you DIG. Call 888-258-0808 and request that all buried utilities locations be identified before digging in unfamiliar ground. Do not let the loader or attachment contact buried electrical power lines, utilities or gas lines. Contact with electrical power lines can result in serious bodily injury or electrocution. If the loader contacts a power line, remain in the tractor seat until the power has been shut off.
OPERATION Never leave the Implement and Power Unit unattended while the Implement is in the raised position. Accidental operation of a lifting lever or a hydraulic failure may cause the implement to suddenly fall causing serious injury or possible death to anyone who might inadvertently be under the Implement. Lower the implement carefully to the ground. Do not put hands or feet under lifted components. (SPU-3) Make sure the hydraulic quick disconnects are fully seated into the connections.
OPERATION THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These manuals must be read and explained to any operator who cannot read. Never allow someone to operate the implement and tractor without complete operating instructions.
OPERATION 1947/2047 01/11 © 2011 Alamo Group Inc. Operation Section 4-25 OPERATION Lift and roll back of bucket will increase efficiency because...
OPERATION A level bucket throughout the lifting cycle resists bucket lift and increases breakaway effort. OPERATION 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. LIFTING THE LOAD When lifting the load, keep the bucket positioned to avoid spillage.
OPERATION CARRYING THE LOAD Position bucket just below tractor hood for maximum stability and visibility, whether bucket is loaded or empty. When transporting the load, keep bucket as low as possible, to avoid tipping, in case a wheel drops in a rut. 1947/2047 01/11 © 2011 Alamo Group Inc. Operation Section 4-27 OPERATION Use extreme care when operating loader on a slope, keep bucket as low as possible. This keeps center of gravity low and will provide maximum stability.
OPERATION DUMPING THE BUCKET OPERATION Lift bucket high enough to clear side of vehicle. Move tractor in as close as possible to side of vehicle, then dump bucket. LOWERING THE BUCKET After bucket is dumped, back away from vehicle while lowering and rolling back bucket. 1947/2047 01/11 © 2011 Alamo Group Inc.
OPERATION OPERATING WITH FLOAT CONTROL During hard surface operation, keep bucket level and put lift control in float position to permit bucket to float on working surface. If hydraulic down pressure is exerted on bucket, it will wear faster than normal. OPERATION Float will also prevent mixing of surface material with stockpile material. Float position will reduce the chance of surface gouging when removing snow or other material. 1947/2047 01/11 © 2011 Alamo Group Inc.
OPERATION LOADING FROM A BANK Choose a forward gear that provides sufficient ground speed for loading. OPERATION Exercise caution when undercutting high banks. Dirt slides can be dangerous. Load from as low as possible for maximum efficiency. Loader lift and breakaway capacity diminish as loading height is increased. Side cutting is a good technique for cutting down a big pile.
OPERATION Another method for large dirt piles is to build a ramp approach to the pile. 1947/2047 01/11 © 2011 Alamo Group Inc. Operation Section 4-31 OPERATION It is important to keep the bucket level when approaching a bank or pile. This will help prevent gouging the work area.
OPERATION PEELING AND SCRAPING OPERATION Use a slight bucket angle, travel forward and hold lift control forward to start the cut. Make a short 5 to 8 foot angle cut and break out cleanly. With bucket level, start a cut at notch approximately 2 inches deep. Hold depth by feathering bucket control to adjust cutting lip up or down. When front tires enter the notch, adjust lift cylinder to maintain proper depth. Make additional passes until desired depth is reached.
OPERATION LOADING LOW TRUCKS OR SPREADERS FROM A PILE For faster loading, minimize angle of turn and length of run between pile and spreader. Back grade occasionally with a loaded bucket to keep working surface free of ruts and holes. Also, hold lift control forward so full weight of bucket is scraping ground. OPERATION Do not roll bucket over and attempt to backgrade.
OPERATION BACKFILLING OPERATION Approach pile with a level bucket. Poor methods actually move no more dirt and make it more difficult to hold a level grade. Do not use bucket in dumped position for bulldozing. This method, shown above, will impose severe shock loadings on dump linkage, bucket cylinder and tractor. 1947/2047 01/11 © 2011 Alamo Group Inc.
OPERATION Leave dirt in bucket. Dumping on each pass wastes time. 1947/2047 01/11 © 2011 Alamo Group Inc. Operation Section 4-35 OPERATION Operate tractor at right angles to ditch. Take as big a bite as tractor can handle without lugging down.
OPERATION OPERATION Leave dirt which drifts over side of bucket for final cleanup. Pile dirt on high side for easier backfilling on a slope. HANDLING LARGE HEAVY OBJECTS 1. Using front end loaders for handling large heavy objects such as large round or rectangular bales, logs and oil drums is not recommended. 2. Handling large heavy objects can be extremely dangerous due to: • Danger of tractor rolling over. • Danger of up-ending tractor.
OPERATION 7.2 Operating Bale Spear Operate the bale spear using extreme caution. Sharp points on bale spear can cause serious injury or death. Because of size and weight of large bales, extreme care must be taken in handling them. Be aware of forces acting on stacked bales due to gravity and keep workers far from zones of potential hazard from shifting or falling bales. DO NOT ALLOW BYSTANDERS! Keep bale spear and loader boom clear of overhead lines.
OPERATION OPERATION Carry bales as low to the ground as possible to allow maximum visibility and avoid tipping. 7.3 Shutting Down the Implement Park the tractor on a level surface, place the transmission in park or neutral and apply the parking brake, lower the attached implement to the ground, shut down the engine, remove the key, and wait for all motion to come to a complete stop before exiting the tractor. OPS-L- 0014 8. Loader Storage Never allow children to play on or around Tractor or Implement.
OPERATION 9. Transporting the Tractor and Implement Never allow children or other persons to ride on the Tractor or Implement. Falling off can result in serious injury or death. (SG-10) Before transporting the Tractor and Implement, determine the proper transport speeds for you and the equipment. Make sure you abide by the following rules: Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly to determine the stopping characteristics of the Tractor and Implement.
OPERATION Lower the loader to the bed of the truck or trailer when transporting the tractor and loader with a truck. Measure to ensure the transport height does not exceed the legal limits. Contact with overhead obstructions or power lines can cause property damage or serious injury. (SL-34) OPERATION Before dismounting the tractor and loader, lower the loader to the ground or onto solid support blocks. Sudden dropping of the loader and attachment could result in serious injury.
OPERATION Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in such a way as to be clearly visible and legible. When transporting the Equipment use the Tractor flashing warning lights and follow all local traffic regulations. (SG-6) The SMV (Slow-Moving Vehicle) emblem is universal symbol used to alert drivers of the presence of equipment traveling on roadways at a slow speed. SMV signs are a triangular bright orange with reflective red trim for both easy day and night visibility.
OPERATION When operating on public roads, have consideration for other road users. Pull to the side of the road occasionally to allow all following traffic to pass. Do not exceed the legal speed limit set in your country for agricultural tractors. Always stay alert when transporting the tractor and implement on public roads. Use caution and reduce speed if other vehicles or pedestrians are in the area. OPS-L- 0020 OPERATION 9.
OPERATION 10. Troubleshooting Guide POSSIBLE CAUSE POSSIBLE REMEDY Loader slow or will not lift and/or dump Hydraulic oil too heavy. Change to proper oil. Oil filter plugged. Hydraulic pump worn. Oil line restricted or leaking. Cylinder leaks internally. Faulty relief valve (tractor). Clean or replace filter. Repair or replace pump. Check all hoses and tubes for leaks, damage or restrictions.
