1. SAFETY FIRST
WSM000001INI0001US1
BEFORE YOU START SERVICE
• Read all instructions and safety instructions in this
manual and on your machine safety decals.
• Clean the work area and machine.
• Park the machine on a stable and level ground, and
set the parking brake.
• Lower the implement to the ground.
• Stop the engine, then remove the key.
• Disconnect the battery negative cable.
• Hang a "DO NOT OPERATE" tag in the operator
station. WSM000001INI0010US0
START SAFELY
• Do not do the procedures below when you start the
engine.
– short across starter terminals
– bypass the safety start switch
• Do not alter or remove any part of machine safety
system.
• Before you start the engine, make sure that all shift
levers are in neutral positions or in disengaged
positions.
• Do not start the engine when you stay on the ground.
Start the engine only from operator's seat.
WSM000001INI0015US0
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 try 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, could result in minor or moderate
injury.
IMPORTANT
• Indicates that equipment or property damage could result if instructions are not followed.
NOTE
• Gives helpful information.

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 operate below the machine that only a jack
holds. Always use a safety stand to hold the
machine.
• 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.
WSM000001INI0012US0
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.

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. WSM000001INI0006US0
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. WSM000001INI0007US0
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. WSM000001INI0008US0
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.
