WSM000001IN006US0
NO SMOKING OR OPEN FLAMES WHILE FUELING
• Fuel is extremely flammable and dangerous.
Never smoke near fuel. IF fuel is spilled on the
machine, its engine, or electrical parts, it may
cause a fire. If fuel is spilled, wipe it all up
immediately.
• Never smoke while filling machine with fuel. And
always tighten the fuel cap securely and wipe up
any spilled fuel.
RY9212001INI0012US0
• Before getting of/off of the machine, clean off
around the steps so there is no mud on them.
Always give yourself 3-point support when getting
on/off the machine
CAUTION
• 3-point support means using both legs and
one hang or both hands and one leg as you
climb up/down.
RY9212038INI0003US0
• Do not remove the radiator cap when the engine
operates, or immediately after it stops. If not, hot
water can spout out from radiator. Only remove
the radiator cap when it is at a sufficiently low
temperature to touch with bare hangs. Slowly
loosen the cap to release the pressure before you
remove it fully.
• The engine, muffler, radiator, hydraulic line, etc.,
have parts that remain very hot even after the
engine has been stopped. Be sure to avoid these
parts, as touching them can result in burns.
Radiator coolant, hydraulic fluid and oil also
remain hot. Therefore, do not attempt to remove
caps and plugs, etc., before these fluids have
sufficiently cooled.
• Make sure the coolant temperature has dropped
sufficiently before opening the radiator cap. Also
since the inside of the radiator is pressurized,
when removing the cap, first loosen it to release
the pressure before removing the cap completely.
• Grease is under high pressure inside the
hydraulic cylinder. It is very dangerous to
loosen a grease nipple quickly as it may shoot
off. Always loosen grease nipples slowly.
• And never face a grease nipple while loosening
it.
• The pressure in the hydraulic circuit stays at
pressure even after the engine stops. Before
removing parts, such as hydraulic devices from
the machine, first release the pressure. Please
not that when releasing residual pressure, the
machine itself and/or implements may move
without warning, so be very careful hen releasing
the pressure.
• Oil gushing out under pressure is extremely
dangerous as it may pierce your skin or your
eyes. Similarly, oil leaking out of pinholes is not
visible. So when checking for oil leaks, always
wear safety glasses and gloves and use a piece
of cardboard or a woo block to shield yourself
from oil.
• Do no open a fuel system under high pressure.
The fluid under high pressure the 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 engine 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 that DC100 V in
the ECU and is applied to injector.

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.
WSM000001INI0005US0
DISPOSE OF WASTE FLUIDS PROPERLY
• Never dispose of waste fluids on the ground, in the
gutter, a river, pond or lake. Always dispose of
hazardous substances like waste oil, coolant and
electrolytic fluid in accordance with the relevant
environmental protection regulations.
• Keep the safety plates clean so they can be read. If
a safety plate is damaged and comes off or be-
comes illegible, put a plate with the same warnings
back in its place.
• Make sure the lift arm stopper is properly
engaged before performing any work beneath
raised lift arms. Never attempt to do any work
or move under the lift arms when they are not
properly supported.
• Keep in mind that the lift arms may fall whenev-
er hydraulic lines are disconnected, loosened,
or removed. Any malfunction or failure in the
hydraulics can also cause lift arms to drop.
• Always perform the necessary repairs or service
whenever the lift arm stopper becomes dam-
aged or malfunctioned, or parts are missing.
Damaged or malfunction the lift arm stopper
may cause the lift arms to fall causing serious
injury or death.
(1) Life arm stopper
• When you need to access the underside of the
machine for maintenance purposes, be sure to
support the machine with a safety stand.
Getting under the machine while supporting the
machine by machine’s own hydraulic cylinder or
using a hydraulic jack can be extremely danger-
ous in the event of a hydraulic fluid leakage or
similar mishap.
(1) Safety Stand
• Whenever it is necessary to open the engine
covers or hood in order to service the machine,
always prop them open.
• If it is absolutely necessary to run the engine
while working o the machine, make sure your
