BEFORE SERVICING AND REPAIRING
SAFETY FIRST
•Wear a suitable hearing protective device such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises.
KiSC issued 04, 2014 A
SAFETY STARTING
SAFETY WORKING
•Escaping fluid (fuel or hydraulic oil) under pressure can penetrate the skin causing serious injury. Relieve pressure before disconnecting hydraulic or fuel lines. Tighten all connections before applying pressure.
•Do not work on the machine while under the influence of alcohol, medication, or other substances or while
•Use tools appropriate to the work. Makeshift tools, parts, and procedures are not recommended.
2 07-E3B SERIES, WSM SAFETY INSTRUCTIONS
•High voltage exceeding 100 V is generated in the ECU, and is applied to the injector. Pay sufficient caution to electric shock when performing work activities.
•Unauthorized modifications to the engine may impair the function and / or safety and affect engine life.
•Do not touch the rotating or hot parts while the engine is
•Wearfatigued.close fitting clothing and safety equipment appropriate to the job.
•When servicing is performed together by two or more persons, take care to perform all work safely.
•Neveroperating.remove the radiator cap while the engine is operating, or immediately after stopping. Otherwise, hot water will spout out from radiator. Only remove radiator cap when cool enough to touch with bare hands. Slowly loosen the cap to first stop to relieve pressure before removing completely.
•Do not start the engine by shorting across starter terminals or bypassing the safety start switch.
•Do not open high-pressure fuel system. High-pressure fluid remaining in fuel lines can cause serious injury. Do not disconnect or attempt to repair fuel lines, sensors, or any other components between the high-pressure fuel pump and injectors on engines with high pressure common rail fuel system.
•Fuel is extremely flammable and explosive under certain conditions. Do not smoke or allow flames or sparks in your working area.
•Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, clothing and cause blindness if splashed into eyes. Keep electrolyte away from eyes, hands and clothing. If you spill electrolyte on yourself, flush with water, and get medical attention immediately.
•If the engine must be operating to do some work, make sure the area is well ventilated. Never operate the engine in a closed area. The exhaust gas contains poisonous carbon monoxide.
3 07-E3B SERIES, WSM SAFETY INSTRUCTIONS
VENTILATE WORK AREA
•To avoid sparks from an accidental short circuit, always disconnect the battery negative cable first and connect it last.
•Make sure that no fuel has been spilled on the engine.
PREVENT ACID BURNS
DISPOSE OF FLUIDS PROPERLY
•Do not pour fluids into the ground, down a drain, or into a stream, pond, or lake. Observe relevant environmental protection regulations when disposing of oil, fuel, coolant, electrolyte and other harmful waste.
KiSC issued 04, 2014 A
AVOID FIRES
•Battery gas can explode. Keep sparks and open flame away from the top of battery, especially when charging the battery.
PREPARE FOR EMERGENCIES
•Keeptimes. emergency numbers for doctors, ambulance service, hospital and fire department near your telephone.
