Section A - Safety
NOTE
Loss of Battery power will result if the switch is left inthe ON position.
ONLY when you have taken these precautions can you be sure it is safe to proceed. Failure to follow the above
procedure, could lead to death or serious bodily injury.
ADDITIONAL SAFETY REMINDERS
USER/OPERATOR SAFETY PRACTICES as established by applicable industry standards are included in this
Operator’s Manual and are intended to promote SAFE OPERATION of the machine.
These guidelines do not preclude the use of good judgment, care and common sense as may be indicated by the particular
job site work conditions.
It is essential that operators be physically and mentally free of mind altering drugs and chemicals, and thoroughly trained
in the safe operation of the machine. Such training should be presented completely to all new operators and should not
be condensed for those claiming previous experience. Information on operator training is available from several sources
including the manufacturer.
Some photographs in this manual may show Doors, Guards and Shields open or removed for illustration purposes ONLY.
BE SURE that all Doors, Guards, and Shields are in their proper operating positions BEFORE starting the Engine to
operate the unit.
The operator MUST know the capabilities and work applications for the machine, and operate it at speeds slow enough
to insure complete control at all times. When working on slopes or near drop offs, use good judgment. ONLY operators
with sufficient experience should attempt such work.
Be alert and avoid loose or soft surface conditions that could cause sudden tipping or loss of control. Avoid side hill
travel wherever possible by driving up or down the slope. In case of slippage on grade, turn the machine
IMMEDIATELY downhill. Keep the blade crossways and lowered for extra stability when scarifying across slopes.
Operating in virgin terrain (called pioneering) is especially dangerous. Be sure you know how this is done. Avoid falling
branches, trees, and up-turning roots, and do not drive onto brush piles, logs, or large rocks.
IF YOU ARE NOT CAREFUL WHILE OPERATING THIS MACHINE, ANY OF THE ABOVE FACTORS COULD
CAUSE THE MACHINE TO TIP AND THROW YOU OUT OF THE OPERATOR’S STATION, WHICH MAY
CAUSE SERIOUS BODILY INJURY OR DEATH!
ALWAYS wear your seat belt!
ALWAYS keep hands, feet, and arms inside of the Operator’s Station when operating the machine!
ALWAYS wear appropriate personal safety gear as called for by the job or working conditions!
ALWAYS be aware of pinch point areas on the machine such as Wheels to Frame, Cylinders to Frame, Moldboard and
Attachment to Frame!
ALWAYS maintain a safe distance from electric power lines or buried cables, and avoid any electrically charged
conductor! Contact can result in electrocution. Call your proper local authorities for utility line locations BEFORE
starting a job!

Section A - Safety
ALWAYS check the job site for terrain hazards, obstructions and bystanders!
NEVER by-pass the Starter Key Switch when starting the Engine. ALWAYS use the jump-starting procedure detailed
in the Service chapter!
NEVER use your hands to search for hydraulic fluid leaks. Hydraulic fluid is pressurized. Escaping fluid can be invisible
and can penetrate the skin, causing a serious injury! If any fluid is injected into your skin, see a doctor familiar with this
type of injury at once! Injected fluid MUST BE surgically removed by a doctor or gangrene may result!
Do NOT operate the machine where the weight, with all attachments installed, exceeds approved load limits!
Do NOT allow minors or any unqualified personnel to operate or be near the machine unless properly supervised. This
is strictly a single Seat, NO passenger machine!
Do NOT start the Engine or operate any Controls unless properly seated in the Operator’s Seat and ALWAYS wear your
seat belt!
Do NOT operate the machine in an enclosed area without adequate ventilation! Internal combustion engines deplete the
oxygen supply in enclosed spaces and may create a serious hazard unless the oxygen is replaced. This includes the
atmosphere inside the cab when the unit is equipped with an enclosed cab!
Do NOT leave the Operator’s Station with the Moldboard or Attachment raised! ALWAYS lower the Attachment(s) to
the ground, shut off the Engine and engage the Park Brake BEFORE leaving the Operator’s Station!
Do NOT refill the Fuel Tank when the Engine is hot. Allow Engine to cool down BEFORE refilling. A hot Engine can
ignite the fuel if it should spill or splash!
Do NOT smoke while filling the Fuel Tank or working on the fuel or hydraulic systems! Sparks can ignite fumes and/or
fuel!
Do NOT drive too close to a ditch or excavation site. BE SURE that the surrounding ground has adequate strength to
support the combined weight of the machine and Attachments!
ALWAYS be alert for immovable objects such as rocks, tree stumps or roots when blading!
Do NOT remove the Radiator Cap when the Engine reaches operating temperature or becomes overheated. The Engine
Coolant is extremely HOT and is under pressure. Exploding Engine Coolant will cause serious injury. ALWAYS wait
for the Engine to cool down BEFORE removing the Radiator Cap to relieve pressure!
Do NOT loosen or disconnect ANY Hydraulic Lines, Hoses or Fittings without first relieving hydraulic circuit pressure.
Also, be careful NOT to touch any hydraulic components that have been in recent operation. They can be extremely
HOT and can burn you!
Do NOT wear loose or baggy clothing while operating or servicing the machine!
NEVER allow any riders on this machine. NEVER use the machine as a lift for personnel!
MODIFICATIONS, NAMEPLATES, MARKINGS, AND CAPACITIES
Modifications and additions which affect the capacity or safe operation shall NOT be performed without the
manufacturer’s prior written approval. Where such authorization is granted, tags or decals shall be changed accordingly.
All attachments MUST be marked to identify the Attachment(s) and show the approximate weight of the machine and
Attachment combination.

NOTE
If working on any public road or shoulder, be sure the machine is the prescribed distance from the
highway as designated by laws in your area. NEVER lower attachments from any position except when
seated in the operator’s seat.
WORKING APPLICATION TIPS
The type of terrain, grading or backfilling application should determine the best choice for using
hydraulic equipment and attachments on the machine.
When finish-grading or leveling under good conditions, work the material from side to side.
Select the desired working speed by depressing the Forward or Reverse Direction/Speed Control
Pedals, as needed.
NOTE
Grading, loading, and ripping should be done in low CREEP or WORK speed. TRAVEL speed
should be used for moving the machine from place to place.
1. When ditching or sloping, you may find it necessary to raise and/or lower one or both ends of
the Moldboard, whichever prevails in your situation.
To set or maintain the desired cutting depth of the Moldboard, use the Joystick to lower or raise the
Moldboard while SLOWLY driving the machine forward.
A sloping grade may be made by lowering the left or right end of the Moldboard from the horizontal
plane as desired.
1. TILT the Moldboard forward for better use in grading imbedded gravel, soft soils, clay or
sandy terrain. The center position is for general use. Tilting it all the way back is
recommended for efficient cutting of hard surfaces.
For maximum cut, TILT the Moldboard to the extreme backward position. For leveling, begin with the top
of the Moldboard slightly ahead of the bottom.
1. To assist in rolling material to the desired area, on the right or left side, adjust the ANGLE of
the Moldboard accordingly.
2. Side shift the Moldboard to cast material outside of the tires’ path by using the BLADE SHIFT
Control. Side shifting the Moldboard also allows continued grading in a straight path while
avoiding obstructions or obstacles at the end of the Moldboard.
