TM 5-2420-230-24-1
Always lower attachment or implement to ground before working on vehicle. If you must work on a lifted vehicle or
attachment, securely support them.
Do not support vehicle on soft or brittle blocks, hollow tiles, or props that may crumble under continuous load. Do not work
under vehicle that is supported solely by a jack.
2-31. DISPOSAL OF WASTE.
Follow appropriate regulations and Unit standard operating procedures on correct ways to recycle or dispose of waste.
Potentially harmful waste includes such items as oil, fuel, coolant, brake fluid, filters, and batteries. Improper disposal of
waste can threaten the environment and ecology.
Use leak-proof containers when draining fluids. Do not pour waste on ground, down drains, or into any water source.
Air-conditioning refrigerants escaping into the air can damage the atmosphere. Government regulations require a certified
service center to recover and recycle used air-conditioning refrigerants.
2-32. ELECTROMAGNETIC INTERFERENCE.
If you experience problems operating any controls, turn off your SINGAR radio unit. Failure to
comply may result in death or injury to personnel and/or damage to equipment.
Electronic controls, devices, and systems may be susceptible to electromagnetic interference (EMI) if inadequately shielded or
otherwise configured for electromagnetic compatibility. When operating any of the vehicle's controls while the SINGAR
radio is on, EMI could occur. If you notice controls not responding correctly, or at all, turn your SINGAR radio off.
Also, use of the hazard warning lights may cause emissions that could cause interference with some radio communications.
