Do not use the loader if the hydraulic connection is leaking. Leaking oil could allow the loader to fall resulting in a serious crushing injury. (SL-22) 6212 01/11 Operation Section 4-22 © 2011 Alamo Group Inc. OPERATION 6212 01/11 Operation Section 4-23 Always have a heavy attachment, such as a bucket mounted on loader when it is removed from tractor. It is important not to put excessive weight on parking stands with lift cylinder retraction. Damage may result. 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) 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. The air can be purged from the cylinder lines by fully cycling the cylinders several times from the fully closed to fully open position. Sudden or unexpected movement or dropping of the loader and attachment could result in serious injury. (SL-32) 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 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. Before starting any operation, the operator must become familiar with the area to be worked in and any obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area. OPS-L-0033 OPERATION © 2011 Alamo Group Inc. OPERATION 6212 01/11 Operation Section 4-24 8.1 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. 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. OPERATION © 2011 Alamo Group Inc. OPERATION 6212 01/11 Operation Section 4-25 Lift and roll back of bucket will increase efficiency because... OPERATION © 2011 Alamo Group Inc. OPERATION 6212 01/11 Operation Section 4-26 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. LIFTING THE LOAD When lifting the load, keep the bucket positioned to avoid spillage. Loader has mechanical self leveling of attachment in both raise and lower cycle. Attachment can be adjusted by using bucket cylinders. OPERATION © 2011 Alamo Group Inc. OPERATION 6212 01/11 Operation Section 4-27 CARRYING THE LOAD Position bucket just below tractor hood for maximum stability and visibility, whether bucket is loaded or empty. 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. When transporting the load, keep bucket as low as possible, to avoid tipping, in case a wheel drops in a rut. OPERATION © 2011 Alamo Group Inc. OPERATION 6212 01/11 Operation Section 4-28 DUMPING THE BUCKET 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. OPERATION © 2011 Alamo Group Inc. OPERATION 6212 01/11 Operation Section 4-29 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. 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 © 2011 Alamo Group Inc.
