TM 5-2420-222-20-1

WARNING

Although ignition lock switch must be on and battery ground cable connected to test electrical circuit

voltage, turn off ignition lock switch and disconnect battery ground cable before doing resistance tests or

replacing parts. This will keep you from getting shocked and prevent damage to parts and equipment.

WARNING

Do not smoke, use open flame, or allow sparks near batteries. The mixture of oxygen and hydrogen

gases released from batteries is highly flammable and can explode causing serious injury or death.

WARNING

Ether burns easily. If engine starting aid is not properly installed, do not release ether in confined areas or

near open flame. Engine primer fluid cylinder is pressurized to expel ether when fluid injection solenoid is

activated. Do not heat engine primer fluid cylinder or place it in fire.

WARNING

No open flames, welding, grinding, smoking, or use of heat producing devices permitted near fuel tank

and fuel lines during maintenance unless the fuel tank has been cleaned and purged of all flammable

liquids and vapors. Fuel burns easily and fumes are explosive. Keep battery disconnected. Failure to

observe these precautions could cause serious injury.

WARNING

Be careful when removing radiator cap. If engine is hot, escaping steam could burn you. Use a rag to

cover radiator cap to protect your hand. Unscrew cap just enough to allow any built-up steam to escape.

When all pressure has been relieved, unscrew cap the rest of the way, and take it off of radiator.

WARNING

Keep clear of area between main frame and backhoe boom, and other backhoe components, when

backhoe control levers are being operated. There is no clearance for personnel when boom is swung full-

left or full-right.

WARNING

Avoid contact with live steam. Live steam can burn skin, cause blindness, and cause other serious injury.

Be sure to wear protective apron, gloves, and safety goggles when using live steam.
