TS 420 A (EWC) STIHL Cutquik®
This cut-off machine features Electronic Water Control technology and a 14” wheel.
STIHL cut-off machines boast many industry-leading features. That’s why STIHL has become the number one selling brand of cut-off machines worldwide. Likewise, the TS 420 A (EWC) raises the standard of wet-cutting performance and boasts a 14” cutting wheel and Electronic Water Control. A conveniently mounted keypad lets you easily control the flow of water with your thumb, letting you keep both hands on the machine. This water control feature is especially important when you are working from a pressure tank and need to improve your control of the water. The EWC feature is smart enough to stop the water flow at idle and remembers your setting when you start working again. And because it’s a STIHL Cutquik® cut-off machine, you can expect fuel efficiency, power and superior comfort.
NOTE: Abrasive wheel included. Diamond wheel (shown) sold separately.
At STIHL, we dedicate considerable resources toward developing new and innovative technology that increases efficiency and improves performance for our line of construction equipment. STIHL Cutquik® cut-off machines are known for superior fuel efficiency, operator comfort, powerful and precise cutting performance and much more. Check out a few of the features that you’ll find on every STIHL Cutquik® cut-off machine:
- Electronic Ignition provides easier starting and smoother running.
- Anti-Vibration System minimizes the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
- Ergonomic Grip provides an optimal comfortable grip in many working positions.
- High-Performance Cooling System for superior airflow and heat dissipation.

- Long-Life Engine Cylinders provide optimal cooling, lubrication and more power output per cubic centimeter of engine displacement for maximum wear life.
- On/Off Switch is conveniently located on top of handle and recessed to prevent accidental shutdown.

- Protected Decompression Valve reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope.
- Protected Spark Plug is protected yet easy to change.
- Protected Throttle Trigger helps prevent damage.
- Throttle Trigger Lockout must be depressed before the trigger can be activated.
- Bayonet-Style Fuel Cap with dust-resistant seal and retainer for easy use, even with gloves.

Model Features
-
Reduced-Emission Engine Technology - Caring for Nature
The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards. -
Electronic Water Control (EWC)
Electronic Water Control allows the operator to easily adjust the flow of water while cutting and stops the water flow when the machine is at idle. -
X2 Air Filtration System
The X2 Air Filtration System revolutionizes the cut-off machine industry by allowing air filters to last up to a year, based on cutting conditions. Outside air enters the system in a swirling motion, removing 80% of dust particles. This pre-cleaned air is then routed through the primary and secondary air filters before being sent into the engine. The X2 Air Filtration System is virtually maintenance free and maintains an incredible 99.96% cleaning efficiency. -
Anti-Vibration System
STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience. -
Semi-Automatic Belt Tensioning
With consistent, semi-automatic re-tensioning, this feature increases the service life of the belts and shaft bearings. -
Ergonomic Grip
The ergonomic top-handle bar design provides an optimal comfortable grip in any working position. -
IntelliCarb™ Compensating Carburetor
The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box. -
Decompression Valve
The decompression valve reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope.
