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.
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.
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.
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. •...
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.
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.

VIBRATORY DRUM • REAR AXLE 1. PRECAUTIONS FOR DISASSEMBLY AND REASSEMBLY • When removing, installing, disassembling or reassembling the unit, observe the general precautions described below. 1) Precautions for removal work • Coolant that contains antifreeze should be treated as a chemical, and must not be drained carelessly on the ground.
Page 100
VIBRATORY DRUM • REAR AXLE 3) Precautions when work is completed • If coolant has been drained, securely retighten the drain cock and fill with coolant (mixing in long- life coolant) to the specified level. Start the engine and allow the coolant to circulate through the piping.
W AR N ING When lifting the machine body, use an appropriate hoist of sufficient strength. Confirm that the surrounding area SV201-1-06001 SV201-1-06001 is safe, and work in a natural, unstrained posture. Also, to firmly secure the machine body, use a support Lift with crane.
