aiya, shouldn't have go check out the new vacuum....it was really good handy vacuum. just brought it home because the dealer offer me a very very irresistible price, approx 20% off from RCP wo...how not to buy ( better than ct hardware discount )   

function : both dry and wet vacuum, blower and semi auto filter cleaning. dealer told me price will be adjusted again by bosch ( higher price ) but not sure when...he already sold more than 5 units including mine just this morning alone....

not sure what does that mean....no suction mode selection, just turn on and off. i don't have the device to measure DB level but compare to my karcher wd3 premium, karcher was a bit louder and with higher pitch noise compare to this bosch.

here's the video comparing the karcher wd3 with this bosch....forward to the end (14:20), you will be able to hear the noise comparison. this bosch can suck so well ! 

I think it means the powertool connected need to be minimum 100w consumption.
Too low power the vacuum's circuit won't be able to remote trigger by the power tool.

last week bought these new tools:

1hp single stage vacuum pump.
and r410 manifold meter. can't use r22 and r134 connectors to r410 unit.



and successfully installed my first aircond.

now can properly disconnect AC unit and bring down for through cleaning.

If the vacuum is brushed motor you can use those high power dimmer to reduce voltage to the vacuum thus make it turn slower = more quiet.
I haven't try this method yet. 

Got a couple to install.
Since I only need a couple more tools to allow self install so I think why not. Can be used later to properly clean everything or do maintenance work.

And no installer that i've ever paid has ever evacuated the gas line using a vacuum pump to remove air. All just force evac using the precharged gas.

I see most battery got balancing circuit wired in, Bosch its too well covered in wrapping can't see it to confirm.

China made Makita clone battery with less complicated control circuit costs 1/3 of original makita battery.

I open my AL1860CV to take a look at inside circuit, not so complicated actually.
Don't understand what those chips in the does tho. haha. 

In this case, clone Bosch battery should be relative safe coz Bosch;s battery does not require complicated control circuits like other brands. 

actually, it's more to the batt cells itself. they are expensive i read somewhere, and cloned batteries doesn;t produce constant high power output

the electronics are mostly for safety. to cut off power when it overheats. i do notice the batt packs get hot easily when i use it with angle grinder

This battery, many vapers have good knowledge about battery.

Recommend 18650 battery :
Sony VTC 4/5/6
Samsung 25R/30Q
LG HG2

i been playing with 18650 batteries, these battery are common. On 18650 also have two type, one with inbuild circuit one without, and both are use for different purpose. The cheap ones that come with circuit protection are as good as useless, it can try your sensitive device.

The cheap ones cannot product sustained high current drawn. Sometime you risk burning the battery if drain are too high to be handle.

Sometime I'm thinking, is the clone battery actually 2nd grade battery or just the big brands has damn high markup? (to cover for insurance and their team of lawyers in case the battery blow up).

Coz some of the OEM battery seller claims their 18650 are actually from samsung/sony too. 6 years shop in taobao, with some feedback of battery DOA but non complain the battery is under capacity/under power.

Plus some youtube channel that open up OEM batteries to show the cells are actually the same as original.
Thats the thing that got me thinking... 

i would really like to buy one if i really use it, even if once a year. LoL

but the fact is, i still dunno what to use it for 

i try to find some sort of reason to justify my power tools purchase. some good, some are just borderline (the 18v vacuum for example)

hahaha   

did this yesterday, in about 30 minutes.

using an axe it'll take me all morning. and usually very tired after that.

it's not for everyone, since not everyone lives in the jungle and/or have big trees to trim. most people would be content with a pair of pruning scissors.

but please don't buy an electric chainsaw.

was considering that model previously.


but since i do a lot of soldering, went with the solder instead.


this pocket torch i use for small torching, shrink wraps and heating stuffs up.
burning garbage and also as lighter.

larger torching i use the butane cap directly on gas can.

LoL... i too have prince torch... but i use it to light up cigars.

have to use those special odourless butane gas refill

No. this one. zero impurities. recommended by many cigarist

cant remember how much it was. iinm, it's around rm17. this can is already 4 yrs old. still got 1/4 i think

made in england. LoL. come so far away

my prince lighter / mini burner at the right

Went to CT hardware to look for a T10 screw driver. Finally found it, looks like very old stock.
Tested the GAS15PS vacuum, I like the feature and the vacuum is not loud.
But I wonder how much suction will lost after passing through the cyclone.

With the T10 screwdriver, I can open up the ori and clone makita battery to inspect.

Ori makita battery has balancing build in and large circuit board
Clone makita batery has smaller circuit board and no balancing.
Both has temperature probe to prevent overheat.
[attachmentid=9047091]
Ori Makita 18v 4AH RM440
Clone Makita 18v 4AH RM120.

CLone makita use 1 years spoil also worth it. Time will tell...
