    SAFETY 1. GENERAL SAFETY 1-1. Understanding the Safety Symbols and Words The words DANGER, WARNING, and CAUTION are used with the safety-alert symbol. DANGER identifies the most serious hazard. When the symbols DANGER, WARNING and CAUTION are displayed, become alert. Your safety or those around you may be involved. NOTICE is used to provide important information that is not hazard related.
  • Page 16: Qualifications Of Operators And Maintenance Personnel

    SAFETY • The machine is designed specifically for the compaction of asphalt or soil road construction materials. Use of the machine for other purposes such as towing other equipment is considered contrary to the designated use. The manufacturer cannot be responsible or held liable for any damage resulting from such use.
  • Page 17: Pre Start Inspection

    SAFETY • Observe all safety instructions and warnings attached to the machine. • Make sure all safety instructions and warnings on the machine are complete and perfectly legible. • Stop the machine immediately in the event of any malfunction. Report any malfunction immediately to the supervisor or other person of authority.
  • Page 18: Starting

    SAFETY 1-7. Starting • Start the machine only from the driver’s seat and always wear the seat belt. • Watch that the warning lights and indicators during start-up and shutdown are working in accordance with operating instructions. • Watch that no one is in danger before starting and when moving the machine. •...
  • Page 19: Maintenance

    SAFETY • Park behind a safe barrier, use proper flags, and warning devices, especially when parking in areas of heavy traffic. 1-10. Maintenance • In any performing any work concerning the operation, adjustment or modification of the machine or it’s safety devices or any work related to maintenance, inspection or repair, always follow the start-up and shut-down procedures in the Operator’s Manual and the Maintenance Manual.
  • Page 20 Always clean up any spilled fuel. • Ensure safe operation, optimum performance of the machine and its warranty by using only genuine SAKAI replacement parts. • Use only the specified fluids and lubricants. Substitute only products known to be equivalent from reputable manufacturers.
  • Page 21: Transporting The Machine

    SAFETY • Observe all product safety regulations when handling fuel, oils, grease, engine coolant and other chemical substances. Be careful especially when these items are hot as there is a risk of burning or scalding. • Operate internal combustion engines and fuel operated heating systems only in adequately ventilated premises.
