I need to run the biggest Bosch rotary hammer made. Bosch recommends 2700 surge watts. I want my tools and the inverter to last. How Big should I Buy?

As long as you have a large enough battery bank feeding it there should be no problem. I have a series-parallel battery bank with 12 batteries with a 1,400 amp capacity & my inverter never misses a beat.

You are getting close to the maximum output of this inverter for your application. I would feel better about your situation if you got a 4000 watt inverter but that is only part of the story. 2700 watts is 22.5 amps on the 120 volt side of the inverter. the 12 volt side amps will be 225 amps from your battery on start up. that is a heavy load for any battery and your best 12 volt battery configurations will not last long seeing that kind of load very often. One way to extend the battery life in these situations is to parallel the battery with a super capacitor to help with the surge amps. Hope this helps with your decision.

Hi there, this handles all my powers tools and my 10A washing machine with no problem.But you must have good deep-cycle batteries.

Sounds like the 3000 should work fine! I've found this inverter to be very capable!!

The specs says "1240 Watt 120V electric motor" which means you got to have a minimum generator of 1240W so find a 1500W should work or just plug in a regular outlet. I plugged my in a typical outlet.

I have run household appliances as well as different types of shop tools. Small compressors as well, dewalts and porter cable. I don't see why it would not run a craftsmen..Did you have a problem in attempting this? Because the inverter is a modified sine wave, the only items I not run would be rechargeable items, cells, laptops, Makita, dewalt cordless type tools. I am a journeyman electrician and have installed this type of inverter, for those who are on a budget not requiring a a device with better customer interaction..

As I recalled I used a standard 10w 30 oil. This demolition hammer always leaks a little oil when in use. This slight oil leak is normal. It is very important to check the oil level of the demolition Hammer and add oil as needed. Using the Demolition Hammer without oil will ruin the device beyond repair. I have had my Demolition Hammer for years and it has given me lots of use. The only thing I had to replace was the power cord. No big deal! This is an excellent tool and a great value. Good Luck.

The 12 volt PS41 is best at setting assorted screws and small diameter bolts~1/4 dia. If you want to address bolts then you need the heavier 12 Volt with a 1/2 inch chuck and "hammer-drill feature. will do nuts up to 1/2" at best----after that you need a heavy duty 110 v. model. More details would clarify the size of bolts used thus selecting the proper drill for the "JOB"...

I suggest that you visit the manufacturer's website and see if there are machines for international voltage requirements. I have not seen anything in the literature that came with mine that suggests that it will run or that there is a model which will run on 230 v. The Bosch people make a similar machine that may have the capacity to run on 230 v.

I don't know. However you might call Makita or Bosch customer support to see if the hammer receptacles are the same.

I started with decent 2HP connected to another small compressor and that wasn't enough, So I borrowed a Rollaire 5HP and that worked good. So I would say you need a good 5HP to run steady. I don't think you will find another DA sander that runs decent on less than that.

I use Rotella 40 weight oil found at most Napa stores it's used for Diesel engines mostly also. It recommends that kind of oil in the literature the hammer came with.

I have not experimented with other power supplies, I can tell you the Proxxon power supply is 12 volt DC / 2 amp output.I can't tell you how much of that 2 amps the rotary tool uses under normal use. The label on my model 50E rotary tool states 18 volts DC max. and 40 watt power max.Other than being lighter and easier to handle for delicate work, a Dremel tool is what I use most of the time.

Thank you for your question. The 11247 has higher impact energy 5.2 ft/lbs versus the RHH181 with 1.3 ft/lbs. The RHH181 will do the job but it will take longer. If you have further questions please feel free to contact our Bosch Customer Service Representatives at 1-877-BOSCH-99 (1-877-267-2499).

You don't need this power. I would stay with something less expensive & lower power. This rotates at a min of 5,000 RPMs up to 35,000 RPMs & can quickly heat up the nail & finger tip.

I use mine primarily for wood and small metal projects. A lot depends on the blade, of course. Be sure to get a few High Capacity batteries. Because the tool is so small I can carry it, along with several other small Bosch tools in a relatively small case. I often get told how cute my tools are and how diminutive they are... I guess that if I had to do a heavy job and had a big workspace I might opt for a larger tool with a bigger motor in it, but this one suits my needs -- cutting nails from around old windows, trimming small metal rods and a small tree branch now and then.

Thank you for your interest. Chargers need a minimum of 200 watts to be used with an inverter. If you are using a generator be sure to use full sine wave not modified wave. If you have further questions please feel free to contact our Bosch Customer Service Representatives at 1-877-BOSCH-99 (1-877-267-2499)

It's a great tool, but it is probably overkill for your task at hand. You would be way better off with the Bosch Bulldog 11255VSR SDS hammer drill - it's lighter and easier to control, and you will not be disappointed with the performance.

The manual says to use Shell #40 or Shell #15/40, but neither of those were available locally so I have used a good oil #10/40, and it works well and seems to keep the hammer running well.

You should be ok running the polisher with this. This is a pure sine wave converter so it will be better for the tool anyway (versus those el cheapo converter).That said, I would NOT try to run it long with the 400W. It'd be better with 800W unit. Both this unit and the polisher has the overload protection so if forsome reason the load is exceeded either (or both) will shut off. Keep an eye on the Wagan to make sure it's not getting too hot. I'd run it for 30mins or so then wait rather than running for like 2 hours with 4.5A load.
