Important Safety Information
These are common practices that may or may not be applicable to the products described in
this manual.
Dig Safe - Avoid
Underground Utilities
USA: Call 811
CAN: digsafecanada.ca
Always contact your local utility
companies (electrical, telephone,
gas, water, sewer, and others)
before digging so that they may
mark the location of any
underground services in the
area.
Be sure to ask how close you can
work to the marks they
positioned.
Transport Safely
Comply with federal, state, and
local laws.
Use towing vehicle and trailer of
adequate size and capacity. Secure
equipment towed on a trailer with
tie downs and chains.
Sudden braking can cause a towed
trailer to swerve and upset. Reduce
speed if towed trailer is not
equipped with brakes.
Avoid contact with any overhead
utility lines or electrically charged
conductors.
Always drive with load on end of
loader arms low to the ground.
Always drive straight up and down
steep inclines with heavy end of
skid steer or tractor with loader
attachment on the “uphill” side.
Engage park brake when stopped
on an incline.
Maximum transport speed for an
attached equipment is 20 mph. DO
NOT EXCEED. Never travel at a
speed which does not allow
adequate control of steering and
stopping. Some rough terrains
require a slower speed.
As a guideline, use the following
maximum speed weight ratios for
attached equipment:
20 mph when weight of attached
equipment is less than or equal
to the weight of machine towing
the equipment.
10 mph when weight of attached
equipment exceeds weight of
machine towing equipment but
not more than double the weight.
IMPORTANT: Do not tow a load
that is more than double the weight
of the vehicle towing the load.
Tire Safety
Tire changing can be dangerous
and must be performed by
trained personnel using the
correct tools and equipment.
Always maintain correct tire
pressure. Do not inflate tires
above recommended pressures
shown in the Operator’s Manual.
When inflating tires, use a clip-on
chuck and extension hose long
enough to allow you to stand to
one side and NOT in front of or
over the tire assembly. Use a
safety cage if available.
Securely support the attachment
when changing a wheel.
When removing and installing
wheels, use wheel handling
equipment adequate for the
weight involved.
Make sure wheel bolts have been
tightened to the specified torque.
Practice Safe Maintenance
Understand procedure before doing
work. Refer to the Operator’s Manual
for additional information.
Work on a level surface in a clean
dry area that is well-lit.
Lower attachment to the ground and
follow all shutdown procedures
before leaving the operator’s seat to
perform maintenance.
Do not work under any hydraulic
supported equipment. It can settle,
suddenly leak down, or be lowered
accidentally. If it is necessary to work
under the equipment, securely
support it with stands or suitable
blocking beforehand.
Use properly grounded electrical
outlets and tools.
Use correct tools and equipment for
the job that are in good condition.
Allow equipment to cool before
working on it.
Disconnect battery ground cable (-)
before servicing or adjusting
electrical systems or before welding
on equipment.
Inspect all parts. Make certain parts
are in good condition & installed
properly.
Replace parts on this attachment
with genuine Kubota parts only. Do
not alter this attachment in a way
which will adversely affect its
performance.
Do not grease or oil attachment
while it is in operation.
Remove buildup of grease, oil, or
debris.
Always make sure any material and
waste products from the repair and
maintenance of the attachment are
properly collected and disposed.
Remove all tools and unused parts
from the equipment before
operation.

Important Safety Information
Listed below are common practices that may or may not be applicable to the products
described in this manual.
Prepare for Emergencies
Be prepared if a fire starts.
Keep a first aid kit and fire
extinguisher handy.
Keep emergency numbers for
doctor, ambulance, hospital, and
fire department near phone.
911
Wear Personal Protective
Equipment (PPE)
Wear protective clothing and
equipment appropriate for the job
such as safety shoes, safety
glasses, hard hat, and ear plugs.
Clothing should fit snug without
fringes and pull strings to avoid
entanglement with moving parts.
Prolonged exposure to loud noise
can cause hearing impairment or
hearing loss. Wear suitable
hearing protection such as
earmuffs or earplugs.
Operating equipment safely
requires the operator’s full
attention. Avoid wearing
headphones while operating
equipment.
Avoid High
Pressure Fluids Hazard
Escaping fluid under pressure can
penetrate the skin causing serious
injury.
Relieve all residual pressure
before disconnecting hydraulic
lines or performing work on the
hydraulic system.
Make sure all hydraulic fluid
connections are tight and all
hydraulic hoses and lines are in
good condition before applying
pressure to the system.
Use a piece of paper or
cardboard, NOT BODY PARTS, to
check for suspected leaks.
Wear protective gloves and safety
glasses or goggles when working
with hydraulic systems.
DO NOT DELAY. If an accident
occurs, see a doctor familiar with
this type of injury immediately. Any
fluid injected into the skin or eyes
must be treated within
a few hours or
gangrene may
result.
Use Safety
Lights and Devices
A slow moving excavator can
create a hazard when driven on
public roads. They are difficult to
see, especially at night. Use the
Slow Moving Vehicle (SMV) sign
when on public roads.
Flashing warning lights and turn
signals are recommended
whenever driving on public roads.
Use Seat Belt and ROPS
Kubota recommends the use of a
CAB or roll-over-protectivestructures (ROPS) and seat belt
in almost all power machines.
Combination of a CAB or ROPS
and seat belt will reduce the risk
of serious injury or death if the
power machine should be upset.
If ROPS is in the locked-up
position, fasten seat belt snugly
and securely to help protect
against serious injury or death
from falling and machine
overturn.
Keep Riders Off
Machinery
Never carry riders on the power
machine or attachment.
Riders obstruct operator’s view
and interfere with the control of
the power machine.
Riders can be struck by objects or
thrown from the equipment.
Never use power machine or
attachment to lift or transport
riders.

Important Safety Information
These are common practices that may or may not be applicable to the products described in
this manual.
Handle
Chemicals Properly
Protective clothing should be
worn.
Handle all chemicals with care.
Follow instructions on container
label.
Agricultural chemicals can be
dangerous. Improper use can
seriously injure persons, animals,
plants, soil, and property.
Inhaling smoke from any type of
chemical fire is a serious health
hazard.
Store or dispose of unused
chemicals as specified by the
chemical manufacturer.
Avoid Silica Dust
There are guidelines which should
be followed if crystalline silica
(quartz) is present in the dust.
Be aware of and follow OSHA (or
other local, State, or Federal)
guidelines for exposure to airborne
crystalline silica.

machine has such equipment.
Otherwise respirators shall be
worn.
Where respirators are required,
wear a respirator approved for
protection against crystalline silica
containing dust. Do not alter
respirator in any way. Workers who
use tight-fitting respirators can not
have beards/mustaches which
interfere with the respirator seal to
the face.
If possible, change into disposable
or washable work clothes at the
work site; shower and change into
clean clothing before leaving the
work site.
Do not eat, drink, use tobacco
products, or apply cosmetics in
