CHAPTER 4 SAFETY A The above Safety Alert Symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS IN· VOL VED! It stresses an attitude of "Heads Up for Safety" and can be found throughout this Operator's Manual and on the machine itself. BEFORE YOU ATTEMPT TO OPERATE THIS EQUIPMENT, READ AND STUDY THE FOL· LOWING SAFETY INFORMATION. IN ADDI· TION, MAKE SURE THAT EVERY INDIVIDUAL WHO OPERATES OR WORKS WITH THIS EQUIPMENT, WHETHER FAMILY MEMBER OR EMPLOYEE, IS FAMILIAR WITH THESE SAFETY PRECAUTIONS. Our Company AL WAYS takes the operator's safety into consideration when designing its machinery and guards exposed moving parts for his/her protection. However, some areas can NOT be guarded or shielded in order to assure proper operation. In addition, this Operator's Manual and Decals on the machine, warn of further danger and should be read and observed close- ly. A DANGER "DANGER" Indicates an Imminently hazardous situation which, If not avoided, will result In death or serious Injury. A WARNING "WARNING" Indicates a potentially hazardous situation which, If not avoided, could result In death or serious Injury. A CAUTION "CAUTION" Indicates a potentially hazardous situation which, If not avoided, may result In minor or moderate Injury. May also alert against unsafe practices. 8 MANDATORY SAFETY SHUTDOWN PROCEDURE BEFORE unclogging, cleaning, adjusting, lubricating or servicing the unit: 1. Disengage the tractor PTO. 2. Place the tractor transmission in park to prevent any tractor movement and lower unit until it is resting on firm ground. 3. Shut off the tractor engine and remove the starter switch key and take it with you when leaving the tractor seat. 4. Wait for all movement to stop. 5. - Disconnect PTO Driveline from the tractor. 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 Some photographs, used in this manual, may show Doors, Guards and Shields open or removed for il- lustration purposes ONLY. BE SURE that all Doors, Guards and Shields are in their proper operating positions BEFORE starting the tractor engine to operate the unit. AL WAYS wear safety glasses with side shields when striking metal against metal. It is further recommended that a softer (non-chipable) material be used to cushion the blow. Failure to heed could lead to serious injury to the eye(s) or other parts of the body.- NEVER use your hands to search for hydraulic fluid leaks; use a piece of cardboard. Escaping fluid under pressure can be invisible and can penetrate the skin and cause serious injury! If any fluid is injected into your skin, see a doctor at once! Injected fluid MUST BE surgically removed by a doctor familiar with this type of injury or gangrene may result.
