STIHL MS 391 Petrol Chainsaws - Agricultural & LandscapingFeatures: Decompression valve The decompression valve is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as reducing the effort needed to pull the starter rope. The decompression valve is semi automatic; it must be pressed manually before starting, but then closes automatically. Advanced combustion technology Four overflow channels swirl the fuel air mix before

Features:

  • Decompression valve - The decompression valve is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as reducing the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.
  • Advanced combustion technology - Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range.
  • Anti-vibration system - Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.
  • Pre-separation air filtration system - STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.
  • Compensator - This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.
  • Variable-displacement oil pump - Allows a precise, demand-based delivery of oil. It's possible to reduce oil production by up to 50% in the E position. For very long cutting attachments or very dry wood, an additional volume of oil can be added by the user. similar to illustration.
  • Single-lever master control - All important functions such as start, choke, throttle and stop are operated via a single lever.
  • Side-chain tensioner - The tensioning screw can be found on the side of the chainsaw through the sprocket cover. This removes the need for contact with the sharp saw chain.
  • Ematic chain lubrication system - The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%.
  • Tool-free filler caps - Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.

The best!!!!! Don’t let the price fool you.
Size: King (U.S. Standard), Number of Items: 2
I don’t know how much money I’ve spent over the years trying to find the perfect pillow. I ordered these to use only as decor on my bed with some fancy pillow shams I had ordered and guess what- they’re my very favorite pillows I’ve ever gotten for sleeping. How in the world is that possible? So I switched my expensive pillow to my fancy sham and sleep on this every night. Buy it right now!

Comfortable pillows
Color: White, Size: Standard (Pack of 2)
These pillows are great. Not too soft or to hard. They need to be in the dryer for about 15 minutes to fluff up. Perfect buy!

Don’t judge by the size
Color: White, Size: Standard (Pack of 2)
I don’t write reviews here typically but I’ve been on the pillow hunt for years with no luck. Mine are always lumpy and misshapen or too soft or too firm. Don’t judge this pillow by how it looks though because I saw it and thought for sure I wasted money. They are small and not fluffy at all. But OMG I laid down on it and it’s the most comfortable pillow I’ve had in years. Memory foam didn’t work for me but this simple little pillow just allowed me some great sleep. Very happy with this purchase. It’s a simple, no frills pillow that’s perfect for this side sleeper that doesn’t like a too soft pillow.
