    No notes for slide
  • Because injury and death effect more than just you.
  • Every company working employees today has some sort of safety program and the insurance companies reward those companies that have successful programs.
  • You are the one that is primarily responsible for your safety, not the foreman or boss. Know your work zone and the hazards that exist in it.
  • Rain falls and mud flies, snow and ice also occur during winter, these conditions demand for you to be extra cautiou,s because water and steel become very slippery in these conditions.
  • All construction equipment has limited visibility “blind spots” so a complete walk around is vitally important to ensure there are no obstacles around or under the machine prior to start-up.
  • When checking dipsticks it is very important to pull the dipstick wipe it clean then re-insert and pull again to check fluid level. Note some systems require a engine running check for proper fluid level.
  • Most every piece of equipment uses hydraulics to move attachments, this hydraulic system needs to be warmed-up prior to operation.
  • The neutral safety lock should be engaged prior to shutting the machine down.
  • Idling for at least 5 minutes will help to cool the exhaust temperature in the turbo-charger and keep oil flowing to the turbo bearing which continues to spin even after shut down.
  • Note some machines are equipped with electronic fuel shut-off and the engine stops when the key is turned off, just remember to keep the throttle position set to a low idle.
  • There can be a problem with the throttle cable or linkage freezing during severe cold weather preventing the machine from starting, but if you reset the throttle position to a low idle the machine will start and warm-up normally.
