MEYER General, United States Army Official: Chief of Staff ROBERT M. JOYCE Brigadier General, United States Army The Adjutant General Distribution: To be distributed in accordance with DA Form 12-25B, Direct and General Support Maintenance Require- ments for Crane, Wheel Mounted. TM 5-3810-295-34 SAFETY PRECAUTIONS BEFORE OPERATION Make certain that the upper and the carrier have been deprocessed completely before servicing. Make certain that preservatives have been removed from crankcases, fuel tanks, gear cases, machine cases, and the like. Fasten a tag near the radiator filler caps indicating the type antifreeze. Before reeving any line, lay out line so the is no possibility of kinking during reeving process. Do not set up carrier crane near electrical power lines. Be sure to observe all local, state and Federal regulations regarding the safe minimum operating distance to power lines. Personnel should us cam to keep from spilling fuel, coolant and other liquids upon themselves. Exposed parts of the body should not come in contact with metal during cold weather, as serious and painful injury may result. Turn radiator cap slowly and allow pressure to escape before removing it. Disconnect battery cables before o working on electrical components. Lower attachment to the ground before attempting to adjust the boom hoist brake. Serious damage to the equipment or injury to personnel may otherwise result. While in park abort condition the carrier will have no brakes. Always block wheels so as to prevent truck crane motion before placing the machine in park abort position. Do not remove blocking until the carrier is returned to normal brake system operation. Make sure proper program card is installed in the load moment safety computer warning device. DURING OPERATION It is important that both carrier and crane operators avid setting up or operating the crane near electrical power lines. Be sure to observe al local, state and Federal regulations regarding safe minimum operating distance to power lines. Use care when swinging the upper revolving frame without a boom. The crane will tend to be unbalanced toward the counterweight end. Do not rely on the ratchet brake locks on front or rear drum brake pedals to suspend a load. The operator must remain in a position of readiness, with feet on the pedals, at all times that a load is suspended. The boom hoist pawl must be engaged at all times, except when lowering the boom. Do not attempt to engage the boom hoist pawl when lowering the boom. Do not attempt to raise the boom by means of the boom hoist line if the boom tip is be low ground level which supports the carrier. The angle of pull on the boom will be such that the boom may collapse before it can be pulled into the operating position. Do not crank engine for more than 30 seconds continuously without allowing a two minute cooling period. If engine does not start after a few tries stop cranking. Determine cause and correct. AFTER OPERATION The boom hoist pawl must be engaged at all times except when lowering the boom. Personnel should use care to keep from spilling fuel, coolant or other liquids upon themselves. Exposed parts of the body should not come in contact with metal during cold weather as serious or painful injury could result. Turn radiator cap slowly and allow pressure to escape before removing it. The swing brake is not used to stop the upper (revolving frame) from swinging while machine is in operation. It is used solely to prevent the revolving frame from turning while the machine is not in use, such as when it is being moved from place to place. Be sure no hydraulic fluid comes into contact with any brake or clutch lining while performing any maintenance operation. Disconnect battery cables before working on any electrical components.
