These are common practices that may or may not be applicable to the products described
in this manual.
Safety at All Times
Thoroughly read and understand
the instructions given in this
manual before operation. Refer to
the “Safety Label section, read all
instructions noted on them.
Do not allow anyone to operate
this equipment who has not fully
read and comprehended this
manual and who has not been
properly trained in the safe
operation of the equipment.
▲ The operator must not use drugs
or alcohol as they can change the
alertness or coordination of that
person while operating
equipment. The operator should,
if taking over-the-counter drugs,
seek medical advice on whether
he/she can safely operate the
equipment.
▲ Operator should be familiar with all
functions of the unit.
▲ Make sure all guards and shields
are in place and secured before
operating implement.
▲ eep all persons away from
equipment and work area.
▲ Start skid steer with steering
levers and hydraulic controls in
neutral.
▲ Operate implement and loader
arms from the driver’s seat only.
▲ Dismounting from a moving unit
can cause serious injury or death.
▲ Do not allow anyone to stand
between skid steer and implement
while hooking-up to implement.
▲ eep hands, feet, and clothing
away from power-driven parts.
▲ Watch out for objects overhead
and along side such as fences,
buildings, wires, trees, limbs, etc.,
while transporting and operating
attached implement.
▲ Detach and store implement in an
area where children normally do
not play. Secure implement by
using blocks and supports.
Look For The Safety Alert Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control, and accident prevention
are dependent upon the awareness, concern,
prudence, and proper training of personnel involved
in the operation, transport, maintenance, and storage
of equipment.
Be Aware of
Signal Words
A Signal
word
designates a
degree
or
level of hazard seriousness. The
signal words are:
! DANGER
Indicates an imminently hazardous
situation which, if not avoided, will
result in death or serious injury. This
signal word is limited to the most
extreme situations, typically for
machine components that, for
functional purposes, cannot be
guarded.
!
WARNING
Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury, and
includes hazards that are exposed
when
guards are removed. It may
also
be used to alert against unsafe
practices.
!
CAUTION
Indicates a potentially hazardous
situation which, if not avoided, may
result in minor or moderate injury. It
may also be used to alert against
unsafe practices.
For Your Protection
▲ Thoroughly read and understand
the “Safety Label” section, read
all instructions noted on them.
Avoid Underground
Utilities
▲ Dig Safe, Call 811.
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.

These are common practices that may or may not be applicable to the products described
in this manual.
Practice
Safe
Maintenance
▲ Understand procedure before doing
work. Use proper tools and
equipment, refer to Operator’s
Manual for additional information.
▲ Work in a clean dry area.
▲ Lower attached implement to the
ground and follow all shutdown
procedures before leaving the
operator’s seat to perform
maintenance.
▲ Allow implement to cool completely
before working on it.
▲
Disconnect
battery
ground
cable
(
-
)
before servicing or adjusting
electrical systems or before
welding on implement.
▲ Do not grease or oil implement
while it is in operation.
▲ Inspect all parts. Make sure parts
are in good condition & installed
properly.
▲ Remove buildup of grease, oil, or
debris.
▲ Remove all tools and unused parts
from implement before operation.
Use Safety
Lights and Devices
▲ Slow moving self-propelled
equipment, and towed
implements can create a hazard
when driven on public roads. They
are difficult to see, especially at
night.
▲ Flashing warning lights and turn
signals are recommended
whenever driving on public roads.
Transport
Safely
▲ Comply with state and local laws.
▲ Never travel at a speed which does
not allow adequate control of
steering and stopping. Some rough
terrains require a slower speed.
▲ Avoid contact with any over head
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
ramps with load on “uphill” side of
skid steer.
▲ Engage parking brake when
stopped on an incline.
▲
IMPORT
ANT:
Do
not
tow
a
load
That is more than double the weight
of the vehicle towing the load.
▲ Usetowingvehicleandtrailerofadequa
tesizeandcapacity.Secureequipmen
t 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 note
quipped with brakes.
Shutdown and Storage
Before lea ing operator’s
seat:
▲ Lower lift arms and put
attachment flat on the ground.
▲ Turn off engine and engage
parking brake.
▲ If included, raise seat bar and
move controls until both lock.
▲ Remove key to prevent
unauthorized starting.
▲ Use steps, grab-handles and
anti-slip surfaces when getting
on or off the loader.
▲ Detach and store implements in
an area where children normally
do not play. Secure implement by
using blocks and supports.

These are common practices that may or may not be applicable to the products described
in this manual.
Wear
Protective Equipment
▲ Wear protective clothing and
equipment appropriate for the job.
Clothing should be snug fitting
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 radio
headphones while operating
machinery.
Keep
Riders Off
Machinery
▲Never carry riders or use
Machinery as a person lift.
▲Riders obstruct operator’s
view.
▲Riders could be struck by
foreign objects or thrown from
the machine.
▲Never allow children to
operate equipment.
Use Seat Belt and ROPS
▲ Operate only skid steers
equipped with a Roll-Over
Protective Structure (ROPS)
and seat belt.
▲ Fasten seat belt snugly and
securely to help protect against
serious injury or death from
falling and skid steer overturn.
▲ Wearing protective equipment
such as safety shoes, safety
glasses, hard hat, and ear plugs
is highly recommended.
Tire Safety
▲ Tire changing can be dangerous
and should be preformed by
trained personnel using the
correct tools and equipment.
▲ 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.
▲ When removing and installing
wheels, use wheel handling
equipment adequate for the
weight involved.
Avoid High
Pressure Fluids Hazard
▲ Escaping fluid under pressure can
penetrate the skin causing
serious injury.
▲ Avoid the hazard by relieving
pressure before disconnecting
hydraulic lines or performing work
on the 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.
Prepare for Emergencies
▲ Be prepared if a fire starts.
▲ eep a first aid kit and
fire extinguisher handy.
▲ eep emergency numbers for
doctor, ambulance, hospital,
and fire department near
phone.
