Features 

Constant Power

CONSTANT POWER, REGARDLESS OF BATTERY CHARGE STATUS. With other brands of battery tools, the performance usually decreases during work as the battery discharges. This is not the case with STIHL battery power tools with CONSTANT POWER. Thanks to the intelligent electronics, your STIHL power tool works with consistently high power.

Regulation of Operating Pressure and Water Flow

PRECISE DOSAGE. The operating pressure can be variably adjusted to achieve a uniform application of fluid which is optimal for the specific task. This can contribute to lower volumes of the fluid (e.g. pesticide) being used.

LED Charge-Level Indicator

FOR GOOD PLANNABILITY. At the push of a button, the LED charge-level indicator will inform you at any time about your battery’s remaining capacity. This allows you to efficiently plan working hours and charge the battery in good time.

FAQs

What can I use the WSA 40 for?

The WSA 40 is a cut-off machine accessory for the mobile water supply of the cut-off machine. The battery water tank enables the binding of dust particles when cutting mineral building materials and cools the cutting wheel.

What operating time does the WSA 40 achieve with a fully charged AS 2 battery?

It is possible to work with the WSA 40 for up to 30 minutes. A total of up to 12 tank fillings can be applied with one battery charge. The specified working times per battery charge were measured at a pressure setting of 1.5 bar in the energy-saving operating sequence These times may vary depending on the application, pressure setting and water dosage on the cut-off machine.

Does the AS battery included in the set fit other STIHL tools?

Yes, the AS 2 can be used with all other devices of the AS system.

What cut-off machines is the WSA 40 compatible with?

The WSA 40 is compatible with all STIHL cut-off machines thanks to the standard coupling and can be used with any TS or TSA.

Is the WSA 40 compatible with other products, such as the concrete cutter?

The WSA 40 is only compatible with STIHL cut-off machines and cannot be used with the STIHL concrete cutter, as the water flow rate of the battery water container does not meet the minimum requirements of the concrete cutter.

Can the WSA 40 also be used to apply disinfectants, acid-based weed killers (e.g. acetic acids, pelargonic acid, etc.), peroxides, acids, alkalis (e.g. liquid chlorine), solvents, foam, oily liquids (e.g. formwork oil), pesticides, fungicides, insecticides, herbicides or fertilizers'?

The approval of the WSA 40 applies exclusively to water. The battery water container was specially developed for the mobile water supply of the cut-off machine and enables both the binding of dust particles when cutting mineral building materials and the cooling of the cutting wheel.

Great space saver
Color: 2 Tier-Black
I love how this makes my sink so much more organized. For me, it holds a 20oz dish soap, a dish spray, 2 S.O.S. pads, 2 sponges, a steel wool scrubber, a bottle brush, a Stanley cap cleaner, and a sink stopper. I could still fit more if I wanted to. I can move the tall brush holder to whichever side I want, as well as the divider. It was super easy to put together, and functions well by draining all the drips right into my sink, instead of behind it. The black looks great and matches my kitchen well. This organized is built well and keeps mynsink area tidy and hygienic.

It Looks Nice and It Works
Color: 1 Tier-Black
I like it. It is too long for my sink area, but it still works. Next to my sink is a dish rack. One half of the caddy fits perfectly behind it, holding a 16oz bottle of dish soap and a 16oz bottle of multi-surface cleaner. The part of the caddy that fits on my sink ledge holds a sponge, scrubber and scouring pad, The caddy works great at keeping the ledge dry. It is a very nice, well-designed item. I recommend this caddy it's keeps everything organized and dry.

Good for organization, looks neat!
Color: 2 Tier-Black
I've had this for almost a year now and expect to have it for a few more; seems very durable. The drain board thingy requires consistent cleaning every few days, but its done in less than two minutes. I usually wash the entire thing every two weeks to keep it shiny as well. I am seeing a little bit of rust, but it's not too much and it's not noticeable if you don't look for it. It's great for organization and was easy to assemble. A very sturdy and well-sized product.

Serves purpose and holds what it was intended to
Color: 2 Tier-Black, Color: 2 Tier-Black
I like it. Keeps things organized and handy in small kitchen. The attachable bin holding my brushes I put on outside of unit not inside as company pics show it. That bin only has one clip to hold it in place. This makes it a little wobbly if you want to place it on the outside like I did. I used 2 trash bag twisties to help tighten it into place. Doing this made it no longer lose and the inside area space larger to hold both of my soaps. Fits everything I need it to. I appreciated the little lever on bottom that moves for water drainage. My sink design doesn’t work for the other drainage design I found these to have online.
