PLATE AS 4342143 - Caterpillar

Fire Extinguisher
Have a fire extinguisher available and know how to use it. Inspect and have it serviced as recommended on its instruction plate.Electrical System
Never disconnect any charging unit circuit or battery circuit cable from the battery when the charging unit is operating. A spark can cause the flammable vapor mixture of hydrogen and oxygen to explode.When starting from an external source, always connect the positive (+) jumper cable to the POSITIVE (+) terminal of the battery of the engine to be started.To prevent potential sparks from igniting combustible gases produced by some batteries, attach the negative (-) boost ground cable last, to the starting motor NEGATIVE (-) terminal (if equipped) or to the engine block. Check regularly for loose or frayed electrical wires. Have all loose or frayed electrical wires tightened, repaired or replaced before operating the engine. See the Operation Section of this manual for specific starting instructions.Grounding Practices
Proper grounding for the engine electrical system is necessary for proper engine performance and reliability. Improper grounding will result in uncontrolled and unreliable electrical circuit paths.Uncontrolled engine electrical circuit paths can result in damage to main bearings, crankshaft journal surfaces and aluminum components.Engines installed without engine-to-frame ground straps can be damaged by electrical discharge. To prevent electrical discharge damage, check to make sure the engine's electrical system has an engine-to-frame ground strap. For engines which have the alternator connected to an engine component, the ground strap must connect that component to the frame.Most engines have starting motor-to-frame ground straps. These starting motors have electrical insulation systems that are not electrically grounded to the engine. For this reason, the starting motor-to-frame ground strap is the acceptable engine ground.To insure proper functioning of the engine and the engine electrical systems, an engine-to-frame ground strap with a direct path to the battery must be used. This may be provided by way of a starting motor ground, a frame to starting motor ground, or a direct frame to engine ground.All grounds should be tight and free of corrosion. The engine alternator must be battery (-) grounded with a wire size adequate to handle full alternator charging current. The engine comes equipped with an alternator ground wire.Crushing or Cutting Prevention
Support equipment and attachments properly when working beneath them.Never attempt adjustments while the engine is running unless otherwise specified in this manual.Stay clear of all rotating and moving parts. Guards should be in place whenever maintenance is not being performed.Keep objects away from moving fan blades. They will throw or cut any object or tool that falls or is pushed into them.Wear protective glasses when striking objects to avoid injury to your eyes.Chips or other debris can fly off objects when struck. Make sure no one can be injured by flying debris before striking any object.Mounting and Dismounting
Do not climb on, or jump off the engine or stand on components which cannot support your weight. Use an adequate ladder. Always use steps and handholds when mounting and dismounting.Clean steps, handholds and areas of the engine
