If your tool is double insulated (as many are – look for the sign or the fact that it has no earth conductor in its supply) then it does not need an earth.

should be OK but if your concerned there should be a ground tap on the generator, you an run a wire from this to a long piece of metal driven into the ground (earth) a lenght of copper tubing will work great. Also a stronger ground can be achieved by wetting the area around you grounding rod.

Apart from, or in addition to an earth stake, you could also get one of those power boards or extension leads that have a build in earth leakage circuit breaker (ELCB) a.k.a. residual current device (RCD).
Should a current greater than approx 30 mA flow through your body to the earth (heaven forbid), then this device will trip and cut off the power in an instant.

Perfectly safer than the AC power from home.
People got kill by AC power from house because one side of 120 volts AC is grounded by the electricity company to save one piece of transmittion line. Using earth as a conductor. As a person touching the Hot line of AC and standing with bare feet on the floor (ground). Current passing throughs his hand—heart—feet—to ground.
Portable petrol electric generator do not need a ground,because none of it power line buries into the ground and using ground as a conductor. As you touch one side of the power output,you will not get injury,because there is no return to complete the circuit. Unless person want to kill himself by touching both power output with both hands to complete the circuit.
