When ready to start work, use the horn to warn people to stay back; stop the machine if needed; and always check your back before backing up the machine.

4. Machine swing radius
Swing radius accidents are common. How do you think all those scrape marks got on that counterweight? Unfortunately, they are also usually fatal when people are involved.

Thus, it's important to rope off the swing radius around the machine or otherwise secure it. Allow no spectators; use a spotter to keep all people clear.

5. Operation on slopes
Caution is always required when operating on slopes. You might make it up the slope with a load, but coming down is another story! Know the limits of the machine, allow for surface conditions and don't push it.

6. Overhead/buried obstructions
Be aware of overhead obstructions and underground utilities, including electrical lines, water, sewer, gas, telecom, etc.
