Doing the mine blade two-step.[ILLUSTRATIONS OMITTED] Motors If the blades come crashing down when the electrical or manual blade release is used, too little oil or oil contamination could be the culprit. After you've confirmed the oil level is OK, use the electrical switch to raise and lower the blades once more. If they come crashing down again, have your mechanic drain the old oil from each motor and replace it with four ounces of damping damping In physics, the restraint of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipating energy. Unless a child keeps pumping a swing, the back-and-forth motion decreases; damping by the air's friction opposes the fluid, NSN NSN National Stock Number NSN Nokia Siemens Networks NSN National Storytelling Network NSN NATO Stock Number NSN New Substances Notification (CEPA) NSN National Student Number (NZ) NSN Never Say Never 9150-00-607-0897. [ILLUSTRATION OMITTED] Water Damage Heavy rain or high-pressure water can seep into the relay box if any of the cover assembly bolts are missing or if the cover seal is missing or damaged. Water buildup build·up also build-up n. 1. The act or process of amassing or increasing: a military buildup; a buildup of tension during the strike. 2. causes electrical shorts. [ILLUSTRATION OMITTED] Your mechanic can replace a missing or damaged seal with NSN 5330-01277-5647. New bolts come with NSN 5305-00-269-3235. NSN 5310-00637-9541 gets new lock washers. Lifting Belts Take care of the mine clearing blade's lifting belts and they won't let you down. That means using the right lifting techniques. [ILLUSTRATION OMITTED] During operations, always make sure you back the vehicle 8-10 feet before lifting the blades. That keeps the blades from hanging up on anything that'll snap the belts. Never use the mine clearing blade to recover mired mire n. 1. An area of wet, soggy, muddy ground; a bog. 2. Deep slimy soil or mud. 3. A disadvantageous or difficult condition or situation: the mire of poverty. v. vehicles or to lift anything. Either the lifting belts will break or the motors will burn out. Never drive the blade through concertina wire concertina wire n. Barbed wire that is extended in a spiral for use as a barrier, as on a fence. . It'll nick and cut the belts. When that happens, your mechanic has to replace them with new belts, NSN 4020-01-289-8249. Depth Adjustment When you're training with the mine clearing blade, keep the adjusting plate set at its shallowest depth-eight inches. That prevents damage to your tank's engine and the blade's teeth. Travel Lock Locking Pins The travel lock locking pins, NSN 5315-01-382-5953, should be put in the locked position whenever the mine clearing blade is not in use. That keeps the blade from being accidentally dropped while the tank is moving. [ILLUSTRATION OMITTED] Before starting mine clearing operations, move both pins to the stowed position so the blade can be lowered. [ILLUSTRATION OMITTED] Lubing There are only six lube points on each side of the mine clearing blade, but some of them still get missed. There are four lube points on each of the travel lock assemblies. The rest are at the base of the lifting straps. [ILLUSTRATIONS OMITTED] Give each of these lube points a good shot of general purpose aircraft grease grease, mixture of lubricant and thickener. It is used to reduce friction between surfaces from which oils would leak away or cause damage by dripping, or where lubrication must be assured for extended periods. Many greases are mixtures of mineral oil and soap. after every operation. NSN 9150-00145-0268 brings a 6.5-lb can of the grease. Power Cable Make sure the power cable is secured to the fender torsion bar torsion bar Rod or bar that resists twisting (see torque) and has a strong tendency to return to its original position when twisted. In an automobile, a torsion bar is a long spring-steel element with one end held rigidly to the frame and the other end twisted by a . That keeps the cable from getting pinched when the driver's hatch is opened. [ILLUSTRATION OMITTED] Don't Forget the Tank Now that you've got the mine clearing blade checked out, don't forget the tank it's attached to. The blade's weight puts a lot of extra stress on your tank's suspension system Noun 1. suspension system - a mechanical system of springs or shock absorbers connecting the wheels and axles to the chassis of a wheeled vehicle suspension , so check the shock absorber shock absorber, device for reducing the effect of a sudden shock by the dissipation of the shock's energy. On an automobile, springs and shock absorbers are mounted between the wheels and the frame. housings for leaks each time you stop. If the fluid level is low, add lubricating oil, NSN 9150-01-439-0756, until it reaches the halfway point low, add lubricating in the sight glass. Never park your tank with the mine blade in the travel position for an extended period. Lower the mine blade to the ground. If the ground is soft or muddy when in the field, use dunnage DUNNAGE, mer. law. Pieces of wood placed against the sides and bottom of the hold of a vessel, to preserve the cargo from the effect of leakage, according to its nature and quality. 2 Magens, 101, art. 125, 126 Abbott on Shipp. 227. to keep the blades from getting stuck.
