ENGLISH
3. CHECK BEFORE STARTING & OPERATING THE ENGINE
A Be sure to inspect the engine before operation. Do not
operate the engine if there is something wrong with it.
Repair it immediately.
A Ensure all guards and shields are in place before operating
the engine. Replace any that are damaged or missing.
A Check to see that you and others are a safe distance
from the engine before starting.
A Always keep the engine at least 3 feet (1 meter) away
from buildings and other facilities.
A DO NOT allow children or livestock to approach the
machine while the engine is running.
A DO NOT start the engine by shorting across starter
terminals. The machine may start in gear and move. Do
not bypass or defeat any safety devices.
4. KEEP THE ENGINE AND SURROUNDINGS CLEAN
A Be sure to stop the engine before cleaning.
A Keep the engine clean and free of accumulated dirt,
grease and trash to avoid a fire. Store flammable fluids
in proper containers and cabinets away from sparks
and heat.
A Check for and repair leaks immediately.
A DO NOT stop the engine without idling; Allow the
engine to cool down, first. Keep the engine idling for
about 5 minutes before stopping unless there is a
safety problem that requires immediate shut down.
5. SAFE HANDLING OF FUEL AND LUBRICANTS -KEEP AWAY FROM FIRE
A Always stop the engine before refueling and/or
lubricating.
A DO NOT smoke or allow flames or sparks in your work
area. Fuel is extremely flammable and explosive under
certain conditions.
A Refuel at a well ventilated and open place. When fuel
and/or lubricants are spilled, refuel after letting the

3SAFE OPERATION
ENGLISH
6. EXHAUST GASES & FIRE PREVENTION
A Engine exhaust fumes can be very harmful if allowed to
accumulate. Be sure to run the engine in a well
ventilated location and where there are no people or
livestock near the engine.
A The exhaust gas from the muffler is very hot. To
prevent a fire, do not expose dry grass, mowed grass,
oil or any other combustible materials to exhaust gas.
Keep the engine and muffler clean at all times.
A To avoid a fire, be alert for leaks of flammable
substances from hoses and lines. Be sure to check for
leaks from hoses or pipes, such as fuel and hydraulic
fluid by following the maintenance check list.
A To avoid a fire, do not short across power cables and
wires. Check to see that all power cables and wirings
are in good condition. Keep all electrical connections
clean. Bare wire or frayed insulation can cause a
dangerous electrical shock and personal injury.
7. ESCAPING FLUID
A Relieve all pressure in the air, the oil and the cooling
systems before disconnecting any lines, fittings or
related items.
A Be cautious of possible pressure relief when
disconnecting any device from a pressurized system
that utilizes pressure. DO NOT check for pressure
leaks with your hand. High pressure oil or fuel can
cause personal injury.
A Escaping fluid under pressure has sufficient force to
penetrate skin causing serious personal injury.
A Fluid escaping from pinholes may be invisible. Use a
piece of cardboard or wood to search for suspected
leaks: do not use hands and body. Use safety goggles
or other eye protection when checking for leaks.
A If injured by escaping fluid, see a medical doctor
immediately. This fluid can produce gangrene or
severe allergic reaction.

ENGLISH
8. CAUTIONS AGAINST BURNS & BATTERY EXPLOSION
A To avoid burns, be cautious of hot components, e.g.
muffler, muffler cover, radiator, hoses, engine body,
coolants, engine oil, EGR, etc. during operation and
after the engine has been shut off.
A DO NOT remove the radiator cap while the engine is
running or immediately after stopping. Otherwise hot
water will spout out from the radiator. Wait until the
radiator is completely cool to the touch before removing
the cap. Wear safety goggles.
A Be sure to close the coolant drain valve, secure the
pressure cap, and fasten the pipe band before
operating. If these parts are taken off, or loosened, it
will result in serious personal injury.
A The battery presents an explosive hazard. When the
battery is being charged, hydrogen and oxygen gases
are extremely explosive.
A
DO NOT use or charge the battery if its fluid level is below
the LOWER mark.
Otherwise, the component parts may deteriorate earlier
than expected, which may shorten the service life or cause
an explosion. Immediately, add distilled water until the
fluid level is between the UPPER and LOWER marks.
A Keep sparks and open flames away from the battery,
especially during charging. DO NOT strike a match
near the battery.
A
DO NOT check the battery charge by placing a metal object
across the terminals. Use a voltmeter or hydrometer.
A DO NOT charge a frozen battery. There is a risk of
explosion. When frozen, warm the battery up to at least
16°C (61°F).
9. KEEP HANDS AND BODY AWAY FROM ROTATING PARTS
A Be sure to stop the engine before checking or adjusting
the belt tension and cooling fan.
A Keep your hands and body away from rotating parts,
such as the cooling fan, V-belt, fan drive pulley or
flywheel. Contact with rotating parts can cause severe
personal injury.
A DO NOT run the engine without safety guards. Install
safety guards securely before operation.
5SAFE OPERATION
ENGLISH
10.ANTI-FREEZE & DISPOSAL OF FLUIDS
A Anti-freeze contains poison. Wear rubber gloves to
avoid personal injury. In case of contact with skin, wash
it off immediately.
A
DO NOT mix different types of Anti-freeze. The mixture can
produce a chemical reaction causing harmful substances.
Use approved or genuine KUBOTA Anti-freeze.
A Be mindful of the environment and the ecology. Before
draining any fluids, determine the correct way to
dispose of them. Observe the relevant environmental
protection regulations when disposing of oil, fuel,
coolant, brake fluid, filters and batteries.
A When draining fluids from the engine, place a suitable
container underneath the engine body.
A DO NOT pour waste onto the ground, down a drain, or
into any water source. Dispose of waste fluids
according to environmental regulations.
11.CONDUCTING SAFETY CHECKS & MAINTENANCE
A When inspecting the engine or servicing, place the
engine on a large flat surface. DO NOT work on
anything that is supported ONLY by lift jacks or a hoist.
Always use blocks or the correct stands to support the
engine before servicing.
A Disconnect the battery from the engine before
conducting service. Put a "DO NOT OPERATE!" tag on
the key switch to avoid accidental starting.
A To avoid sparks from an accidental short circuit always
disconnect the battery's ground cable (-) first and
reconnect it last.
A Be sure to stop the engine and remove the key when
conducting daily and periodic maintenance, service
and cleaning.
A
Check or conduct maintenance after the engine, coolant,
muffler, or muffler cover have cooled off completely.
A Always use the appropriate tools and fixtures. Verify
that they are in good condition before performing any
service work. Make sure you understand how to use
them before service.
A Use ONLY correct engine barring techniques for
manually rotating the engine. DO NOT attempt to rotate
the engine by pulling or prying on the cooling fan and
V-belt. This practice can cause serious personal injury
or premature damage to the cooling fan and belt.
