INFORMATION 03-M-E3B, 03-M-DI-E3B, 03-M-E3BG, WSM I-1 1. SAFETY FIRST M00000003INI0001US1 BEFORE YOU START SERVICE • Read all instructions and safety instructions in this manual and on your engine safety decals. • Clean the work area and engine. • Park the machine on a stable and level ground. • Let the temperature of the engine decrease before you start a job. • Stop the engine, then remove the key. • Disconnect the battery negative cable. • Hang a "DO NOT OPERATE" tag in the operator station. M00000003INI0002US1 START SAFELY • Do not do the procedures below when you start the engine. – short across starter terminals – bypass the safety start switch • Do not make unauthorized modifications to the engine. This can cause damage and decrease the engine life. M00000003INI0003US1 SAFETY FIRST • This symbol, the industry's "Safety Alert Symbol", is used throughout this manual and on labels on the machine itself to warn of the possibility of personal injury. Read these instructions carefully. • It is essential that you read the instructions and safety regulations before you attempt to repair or use this unit. DANGER • Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING • Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION • Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. IMPORTANT • Indicates that equipment or property damage could result if instructions are not followed. NOTE • Gives helpful information. KiSC issued 07, 2014 A

INFORMATION 03-M-E3B, 03-M-DI-E3B, 03-M-E3BG, WSM I-2 OPERATE SAFELY • Do not use the machine after you consume alcohol or medication or when you are tired. • Put on applicable clothing and safety equipment. • Use applicable tools only. Do not use alternative tools or parts. • When 2 or more persons do servicing, make sure that you do it safely. • Do not touch the hot parts or parts that turn when the engine operates. • Do not remove the radiator cap when the engine operates, or immediately after it stops. If not, hot water can spout out from the radiator. Only remove the radiator cap when it is at a sufficiently low temperature to touch with bare hands. Slowly loosen the cap to release the pressure before you remove it fully. • Released fluid (fuel or hydraulic oil) under pressure can cause damage to the skin and cause serious injury. Release the pressure before you disconnect hydraulic or fuel lines. Tighten all connections before you apply the pressure. • Do not open a fuel system under high pressure. The fluid under high pressure that stays in fuel lines can cause serious injury. Do not disconnect or repair the fuel lines, sensors, or any other components between the fuel pump and injectors on engines with a common rail fuel system under high pressure. • Put on an applicable ear protective device (earmuffs or earplugs) to prevent injury against loud noises. • Be careful about electric shock. The engine generates a high voltage of more than DC100 V in the ECU and is applied to the injector. M00000003INI0004US1 PREVENT A FIRE • Fuel is very flammable and explosive under some conditions. Do not smoke or let flames or sparks in your work area. • To prevent sparks from an accidental short circuit, always disconnect the battery negative cable first and connect it last. • The battery gas can cause an explosion. Keep the sparks and open flame away from the top of battery, especially when you charge the battery. • Make sure that you do not spill fuel on the engine. M00000003INI0005US1 KiSC issued 07, 2014 A

INFORMATION 03-M-E3B, 03-M-DI-E3B, 03-M-E3BG, WSM I-3 KEEP A GOOD AIRFLOW IN THE WORK AREA • If the engine is in operation, make sure that the area has good airflow. Do not operate the engine in a closed area. The exhaust gas contains poisonous carbon monoxide. M00000003INI0006US1 DISCARD FLUIDS CORRECTLY • Do not discard fluids on the ground, down the drain, into a stream, pond, or lake. Obey related environmental protection regulations when you discard oil, fuel, coolant, electrolyte and other dangerous waste. M00000003INI0007US1 PREVENT ACID BURNS • Keep electrolyte away from your eyes, hands and clothing. Sulfuric acid in battery electrolyte is poisonous and it can burn your skin and clothing and cause blindness. If you spill electrolyte on yourself, clean yourself with water, and get medical aid immediately. M00000003INI0008US1 PREPARE FOR EMERGENCIES • Keep a first aid kit and fire extinguisher ready at all times. • Keep the emergency contact telephone numbers near your telephone at all times.
