- Page 9 TEMPERATURE Fahrenheit-Centigrade Conversion. A simple way to convert a fahrenheit temperature reading into a centigrade temperature reading or vice verse is to enter the accompanying table in the center or boldface column of figures. These figures refer to the temperature in either Fahrenheit or Centigrade degrees. If it is desired to convert from Fahrenheit to Centigrade degrees, consider the center column as a table of Fahrenheit temperatures and read the corresponding Centigrade temperature in the column at the left.

On machines with independently operated wheel brakes, lock the brake pedals together when roading to provide equalized brake applications. Dual brake pedals (if equipped) should be locked together for road travel. Use the safety chains for trailed equipment. Lift implements and attachments high enough above the ground to prevent accidental contact with road. When transporting equipment or machine on a transport trailer, ensure the machine is properly secured. - Page 21 When using auxiliary batteries or connecting booster cables to start the engine, use the procedure shown in the operator’s manual. Do not short across terminals. Follow the manufacturer’s instructions when storing and handling batteries. Battery post, terminals, and related accessories contain lead and lead compounds.

DO NOT attach any device to the protective structure for pulling purposes. DO NOT drill holes in the protective structure. The protective structure and interconnecting components are a certified system. Any damage, fire, corrosion, or modification will weaken the structure and reduce your protection. If this occurs, THE PROTECTIVE STRUCTURE MUST BE REPLACED so that it will provide the same protection as a new protective structure. - Page 23 Keep hazardous chemicals out of reach or children or other unauthorized persons. Additional precautions are required for applied chemicals. Obtain complete information from the manufacturer or distributor of the chemicals before using them. Utility Safety When digging or using ground-engaging equipment, be aware of buried cables and other services. Contact your local utilities or authorities, as appropriate to determine the locations of services.
- Page 24 Lifting and Overhead Loads Never use loader buckets, forks, etc. or other lifting, handling, or digging equipment to lift persons. Do not use raised equipment as a work platform. Know the full area of movement of the machine and equipment and do not enter or permit anyone to enter the area of movement while the machine is in operation.
- Page 25 Check the coupler operation periodically for any unusual movement and/or noise. Inspect hydraulic hoses for any leaks or damage. Inspect welds and make any repairs as necessary. Check for any loose bolts. Torque as required. Do not modify the machine or attachments. Such modifications can damage and/or affect the integrity of the attach- ment and can effect safety and function of the attachment and/or machine.
