SAFETY
Understand that your safety and the safety of other persons is measured by how you service and operate this
machine. Know the positions and operation of all controls before you try to operate. MAKE SURE YOU CHECK
ALL CONTROLS IN A SAFE AREA BEFORE STARTING YOUR WORK.
READ THIS MANUAL COMPLETELY and make sure you understand the controls. All equipment has limits. Make
sure you understand the speed, brakes, steering stability and load characteristics of this machine before you start
to operate.
The safety information given in this manual does not replace safety codes, insurance needs, federal, state and
local laws. Make sure your machine has the correct equipment needed by the local laws and regulations.
Case Corporation is continuing to work for your safety by making tractors with better protection and by providing
these rules for safe operation.
●Before starting the engine, be sure all operating controls are in neutral or park lock position. This will eliminate
accidental movement of the machine or start up of power driven equipment. R106E
●Operate controls only when seated in the operators seat. R137A
●Securely fasten your seat belt. Your machine is equipped with a ROPS cab, ROPS canopy or ROPS frame for
your protection. The seat belt can help insure your safety if it is used and maintained. Never wear a seat belt
loosely or with slack in the belt system. Never wear the belt in a twisted condition or pinched between the seat
structural members. Inspect seat belt webbing, buckle and retractors to ensure they are not damaged. If
damage is apparent, repair before operating the tractor. M437A
●A frequent cause of personal injury or death is persons falling off and being run over. Do not permit others to
ride. Only one person - the operator - should be on the machine when it is in operation unless operator training
is being conducted. Trainer and trainee must fasten seat belts at all times. R115C
●Before leaving the tractor, stop the engine, put all controls in neutral or park lock position, remove the key from
the key switch. R301B
●Stay off slopes too steep for safe operation. Shift down before you start up or down a hill with a heavy load.
Avoid “free wheeling”. R123A
●Do not drive on roads, or at high speed anywhere, with the differential lock engaged. Difficult steering will occur
and can result in an accident. In field operation, use the differential lock for traction improvement, but release
for turning at row ends. R116A
●Travel speed should be such that complete control and machine stability is maintained at all times. Where
possible, avoid operating near ditches, embankments and holes. Reduce speed when turning, crossing slopes,
and on rough, slick or muddy surfaces. R109B
WARNING: THIS SAFETY ALERT SYMBOL INDICATES IMPORTANT
SAFETY MESSAGES IN THIS MANUAL. WHEN YOU SEE THIS
SYMBOL, CAREFULLY READ THE MESSAGE THAT FOLLOWS AND
BE ALERT TO THE POSSIBILITY OF PERSONAL INJURY OR DEATH.

●Collision of high speed road traffic and slow moving machines can cause personal injury or death. On roads,
use flasher lights according to local laws. Keep SMV emblem visible. Pull over to let faster traffic pass. Slow
down and signal before turning off. R110E
●Make sure that the weight of a trailed vehicle that is not equipped with brakes, NEVER EXCEEDS the weight of
the machine that is towing the vehicle. Stopping distance increases with increasing speed as the weight of the
towed load increases, especially on hills and slopes. R114B
●Extra weight and bad traction conditions such as mud or ice increase your stopping distance. Remember that
liquid in the tires, weights on the machine or wheels, tanks filled with fertilizer, herbicides or insecticides - all
these add weight and increase the distance you need in which to stop. R138B
●PTO driven machinery can cause serious injury. Before working on or near the PTO shaft, or servicing or
clearing the driven machine, put the PTO lever in the DISENGAGE position and STOP the engine. R154A
●Whenever a PTO driven machine is in operation, the PTO guard must be in place for most operations to prevent
injury to the operator or bystanders. Where attachments, such as pumps, are installed on the PTO shaft
(especially if the tractor PTO guard is moved upward or removed), extended shielding equivalent to the PTO
guard must be installed with the attachment. Install the PTO guard to its original position immediately when the
attachment is removed. R273A
●When doing stationary PTO work and dismounting from the tractor with the PTO running, keep clear of all
moving parts as they are a potential safety hazard. R127A
●When doing stationary PTO work, install the front and rear frame articulation block to prevent accidental
articulation of the tractor. Put the transmission control lever in the park position. R298B
●Never operate the engine in a closed building. Proper ventilation is required under all circumstances. R142A
●Never refuel the machine when the engine is hot or running. Never smoke while refueling. R139C
●Check and service cooling system according to the maintenance instructions. Hot coolant can spray out if the
deaeration tank cap is removed while system is hot. To remove the deaeration tank cap, let system cool, turn to
first notch, then wait until all pressure is released. Scalding can result from fast removal of the cap. R141C
●Hydraulic oil or diesel fuel leaking under pressure can penetrate the skin and cause infection or other injury.
To Prevent Personal Injury:
Relieve all pressure before disconnecting fluid lines.
Before applying pressure, make sure all connections are tight and components are in good condition.
Never use your hand to check for suspected leaks under pressure.
Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your doctor immediately.R149B
●Battery explosion and/or damage to electrical components can result from improper connection of booster
batteries or charger. Connect positive to positive and negative to negative. Externally, battery acid can cause
burns and blindness, and taken internally it is poisonous. R146B
●It is good practice to carry a fire extinguisher on the machine. Be sure that the extinguisher is properly
maintained and be familiar with its proper use. R102B
●Clean tractor of field trash daily or more frequently depending upon conditions. Trash accumulation on the
tractor can cause damage and fire. M791

●Do not turn the steering wheel until everyone is clear of the equipment and the center hinge area. Turning the
steering wheel can swing the tractor and equipment from side to side. R303A
●Always use the hand rails when mounting or dismounting from the tractor. Always face the tractor when
mounting and dismounting. This will provide more secure hand and feet mobility to help prevent slipping and
possible injury. R304A
●Always keep the cab windows and rear view mirrors clean to provide the best all around visibility while
operating the tractor. R416
●Do not pull with elastic tow ropes. Elastic tow rope stores energy. Sudden release may cause injury or death.
M425
●Young children should not be permitted to operate or ride the tractor under any circumstances. M630
●Do not look directly into the High Intensity Discharge Head Lamp. Eye damage can occur. M638
●Do not tamper with the ballast on the High Intensity Discharge Head Lamp as it contains high voltage. Personal
injury or death can occur. M639
●To prevent tractor movement, whenever the tractor is parked with the engine running, the transmission control
lever MUST be in the PARK position to activate the park brake. The park brake is applied automatically when
the engine is shut down regardless of transmission control lever position. M627
●Always start the engine from the operators seat. Never attempt to bypass start, the tractor may suddenly start
and move resulting in serious or fatal injury. M787
●To avoid possible eye damage from microwave signals emitted by the radar sensor, do not look directly into the
sensor face. M788
●The operator cab does not protect against inhaling harmful pesticides or chemicals. Please utilize an approved
respirator or other personal protection equipment as recommended by the chemical supplier when using these
materials. M792
●If you are exposed to or come in contact with hazardous chemicals, you can be seriously injured. The fluids,
lubricants, paints, adhesives, coolants, etc., used with your machine can be hazardous.
●Material Safety Data Sheets (MSDS) provide information about the chemical substances within a product, safe
handling procedures, first aid measures and procedures to be taken when the product is accidentally spilled or
released. MSDS are available from your dealer.
●Before you service your machine, check the MSDS for each fluid, lubricant, etc., used in this machine. This
information indicates what the risks are and how to service the machine safely. Follow this information when
servicing the machine.
●Before you service this machine and before you dispose of the old fluids and lubricants, always remember the
environment. DO NOT put oil or fluids into the ground or into containers that can leak.
●Check with your local environmental or recycling center or your dealer for correct disposal information.
