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 to play on or around 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 Use extreme care when loading, carrying or handling any agricultural fertilizers, chemicals or biological residue. Follow the manufacturer’s handling instructions and wear appropriate Personal Protective Equipment including gloves, safety glasses and respirator when required. If you are using a tractor equipped with a cab, make sure the cab is rated for appropriate environmental exposure. Be safe and always wear proper protection.
SAFETY Never allow children or other persons to ride on the Tractor or Implement. Falling off can result in serious injury or death. (SG-10) Do not mount or dismount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completelystopped. (SG-12) SAFETY Start tractor only when properly seated in the Tractor seat. Starting a tractor in gear can result in injury or death. Read the Tractor operators manual for proper starting instructions.
SAFETY For added safety when lifting loads above the height of the operator, install a certified Falling Object Protective Structure. Shiftable loads, round bales, large loose items, and loader attachments can fall toward the operator resulting in serious injury or death. Falling Object Protective Structure (FOPS) rated Cab may be obtained from the tractor dealer or other sources.
SAFETY 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. (SL-08) SAFETY Do not let the loader or attachment contact electrical power lines. Contact with electrical power lines can result in serious injury or electrocution. If the loader attachment contacts a power line remain in the tractor seat until the power has been shut off.
SAFETY 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.
SAFETY 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.
SAFETY Make sure all tractor and loader guards are in place and properly functioning. Do not use an attachment if the roll back guards are damaged or missing. The roll back guards prevents items carried in the attachment from rolling back onto the operator causing serious injury. For added safety when lifting loads above the height of the operator, install a certified Falling Object Protective Structure.
SAFETY 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.
SAFETY 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) Do not modify or alter this Implement. Do not permit anyone to modify or alter this Implement, any of its components or any Implement function. (SG-8) Do not operate this Equipment with hydraulic oil or fuel leaking.
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) Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and hose connections. Relieve hydraulic pressure before performing maintenance or repairs.

Make sure the Loader is resting on the ground or securely blocked up and all hydraulic pressure has been relieved.
OPERATION 6. Driving the Tractor and Loader 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 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) Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and precautions to take while driving with an attached implement.
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. (SL-21) The Boom is designed only to position and operate the Bucket which is attached to it.
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) OPERATION Do not raise the loader into an overhead structure or allow a raised attachment to contact overhead structures.
OPERATION Do not use loader as a jack to raise the tractor tires off the ground. The loader could fail causing the tractor and loader to fall to the ground resulting in serious injury. (SL-25) 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.
OPERATION If the loader valve controls fail to functions properly discontinue use of the tractor and loader until the controls are properly repaired. Sudden or unexpected movement or dropping of the loader and attachment could result in serious injury. (SL-31) OPERATION Make sure all air is purged from the hydraulic system before using the loader. Air in the system can cause the loader to respond sluggishly or with unexpected movement.
OPERATION 7.1 Operating the Loader The following text and illustrations offer suggested loader and tractor operating techniques. FILLING THE BUCKET Approach and enter the pile with a level bucket. OPERATION Loaders with 1-lever control, ease lever back toward you to lift and roll back bucket. With series valve, prevent loader stall by not lifting and rolling back at the same time. 2647 01/11 © 2011 Alamo Group Inc.
OPERATION OPERATION Lift and roll back of bucket will increase efficiency because... A level bucket throughout the lifting cycle resists bucket lift and increases breakaway effort. 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.
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. 2647 01/11 © 2011 Alamo Group Inc. Operation Section 4-25 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. 2647 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.
OPERATION OPERATION Side cutting is a good technique for cutting down a big pile. If the pile sides are too high and liable to cause cave-in, use loader to break down the sides until a slot can be cut over the top. Another method for large dirt piles is to build a ramp approach to the pile. 2647 01/11 © 2011 Alamo Group Inc.
OPERATION It is important to keep the bucket level when approaching a bank or pile. This will help prevent gouging the work area. 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.
OPERATION OPERATION Make additional passes until desired depth is reached. During each pass, use only bucket control while working depth. This will allow you to concentrate on controlling bucket angle to maintain a precise cut. 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.
OPERATION BACKFILLING Approach pile with a level bucket. 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. 2647 01/11 © 2011 Alamo Group Inc. Operation Section 4-31 OPERATION Poor methods actually move no more dirt and make it more difficult to hold a level grade.
OPERATION OPERATION Leave dirt in bucket. Dumping on each pass wastes time. Operate tractor at right angles to ditch. Take as big a bite as tractor can handle without lugging down. 2647 01/11 © 2011 Alamo Group Inc.
OPERATION Leave dirt which drifts over side of bucket for final cleanup. 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. • Danger of object rolling or sliding down loader arms onto operator. 3.
OPERATION 8. Loader Storage Never allow children to play on or around Tractor or Implement. Children can slip or fall off the Equipment and be injured or killed. Inadvertent contact with controls can cause the Implement to shift or fall crushing themselves or others. (SG-25) OPERATION Properly preparing and storing the loader at the end of the season is critical to maintaining its appearance and to help ensure years of dependable service.
OPERATION 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. Before transporting the Tractor and Implement, determine the proper transport speeds for you and the equipment.
OPERATION OPERATION Before transporting the tractor and loader, idle the tractor engine. When transporting, carry the loader as low as possible maintaining adequate ground clearance and visibility. Reduce tractor ground speed when transporting a load. Take extra care when traveling over rough terrain or on slopes. OPS-L-0011 Before transporting the tractor on a public roadway or boarding a trailer for transport, the tractor brake pedals should be locked together.
OPERATION Make sure that all tractor flashing warning lights, headlights, and brake/tail lights are functioning properly before proceeding onto public roads. While newer model tractors have plenty of lighting to provide warning signals and operating lighting, most older models are only equipped with operating lights. Consult an authorized tractor dealer for lighting kits and modifications available to upgrade the lighting on older tractor models.
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. Replace damaged or restricted hoses or tube oil lines. Inspect, clean, repair or replace valve.
OPERATION POSSIBLE CAUSE POSSIBLE REMEDY Excessive wear on cutting edge Bucket is riding on cutting edge instead of wear runners. Use boom “FLOAT” position or bucket level indicator to ensure bucket rides on wear runners. Bucket cutting edge not flat on the ground. Rear axle on tractor not level from side to side. With tractor on level surface, compare rear axle height from left to right, measuring from axle center to ground.
