Your gen. is a 2000 wt max 1000wt running out put. Means it will start your jackhammer but will not maintain the wattage to run it long. You are using the max it has to put out. So let me try to explain - 2000 watt max output works like this - We will use a fan as an example. A fan sitting still and not turning takes more amperage/watts to start. that is called lock rotor amps. So lets say the fan is a 1000w to run. 2000w start the fan turning then it takes 1000w to keep it turning. Your gen. can start the fan but not keep it running it is using all it has to put out, now if that fan only uses say 750 w running watts you have some head room to keep it running with out things getting hot. Hope this is clear as mud.
