Description
Proof of a current and valid license is required to purchase this machine. This will be requested prior to despatch in line with the manufacturer’s requirements.
The MSA 190 T is a powerful top-handle chainsaw designed for use by professional arborists. It has been designed for small to medium pruning tasks, such as crown maintenance and removing dead wood. Designed with professionals in mind, it has comparable power to the petrol MS 194 T and offers a lower-weight alternative to the STIHL MSA 220 T battery-powered top-handle chainsaw.
With an excellent power-to-weight ratio, this chainsaw is comfortable to use over long periods of time and is compact and perfectly balanced in its design – when used with the AP 200 S battery, it counterbalances the guide bar for effortless control and reduces wrist strain. The MSA 190 T has a high chain speed of up to 20 m/s, which makes it ideal for fine and precise cuts. The bumper spikes help to fix the chainsaw in place on wood, making precise cuts easy. As the chainsaw is battery-powered, it can be used in noise-sensitive areas such as schools, hospitals, and residential areas.
Fitted as standard with the 1.1mm 3/8” P PS3 Pro saw chain and Light 01 guide bar for increased performance. An eyelet accessory is available separately which allows the MSA 190 T to be carried easily alongside the operator’s belt carabiner. Like most AP System tools, the MSA 190 T is IPX4 rated meaning it can be used in all types of weather conditions.
With a fully charged AP 200 S battery, the MSA 190 T has a working time of up to 48 minutes, which can be extended when using the AP 300 S or AP 500 S battery.
Must be used with AP 200 S, AP 300 S or AP 500 S battery for full performance.

STIHL Chainsaw Maintenance Guide

Maintenance measures each time you use your chainsaw
- Before using your chainsaw, check it is safe. Start with a visual check: can you see any damage on the chainsaw or its controls? Are the guide bar, saw chain, chain catcher and other accessories correctly fitted? If a repair is needed, take the chainsaw to a dealer to look at.
- Test the throttle trigger, throttle trigger lockout, choke knob, stop switch and master control lever (subject to model).
- Test to make sure the chain brake is working.
- Check the condition of the saw chain (does it need further maintenance in terms of sharpness and chain tension?) and the chainsaw guide bar.
- Is the chain properly lubricated?
- Check whether the fuel tank cap and the oil tank cap are sealed.
- There must not be any fuel leaking from the chainsaw.
- After use, clean the chainsaw and remove any shavings and dust.
Periodic maintenance measures for long-term chainsaw care
- Clean the guide bar (the sprocket nose, the oil inlet hole, the oil outlet channel and the bar groove), the chain sprocket cover, the cylinder fins and the inside of the shroud and the filter cover.
- We recommend turning over and, if necessary, deburring the guide bar at regular intervals or when you notice signs of wear.
- After breaking in a new saw chain, check the chain tension and ensure the chain is always lubricated.
Ongoing chainsaw maintenance is key
Cleaning after every use is the most important maintenance measure to keep your chainsaw in great condition. That’s because it picks up resin, sawdust and other substances which, in combination with the chain lubricant, can soon cause real problems: resin accumulates and hardens, and can eventually make its way into the housing and guide bar. Our advice is that all traces of resin should be removed from the bar and housing at the earliest possible opportunity. We recommend you make STIHL Varioclean part of your maintenance routine when cleaning your chainsaw.
An overview of maintenance for electric and petrol chainsaws
Electric chainsaw maintenance
Electric chainsaws have a simpler construction than petrol tools, so they require fewer cleaning and maintenance steps:
- Remove shavings and dust from the whole chainsaw (use a soft brush, paintbrush or STIHL resin solvent)
- Clean the sprocket area with a damp cloth or STIHL resin solvent
- Clean the bar groove
- Remove any burrs forming on the bar groove
- Clean the chainsaw ventilation slits with a paintbrush
Use a STIHL guide bar leveller to remove burrs from the guide bar.
Cordless chainsaw maintenance
As well as the measures listed above, if you have a cordless chainsaw, we recommend some additional measures:
- Remove foreign bodies from the battery slot and clean the battery slot with a damp cloth.
- Clean the electrical contacts in the battery slot with a paintbrush or soft brush.
Petrol chainsaw maintenance
If you have a petrol chainsaw, there are a few other maintenance considerations to keep in mind:
- Check that the fuel and chain lubricant tanks are sealed and that no fuel or lubricant is leaking from them.
- Regularly clean the air filter and the air filter housing.
- Check the spark plug for wear and remove any soot on a regular basis.
