Stihl BG-86 user manual

The Stihl BG86 leaf blower can reach air speeds of up to 190 mph (306 kph).

The L and H on a STIHL blower, specifically the BG-86 model, refer to the Low and High speed adjustment screws for the carburetor. These screws are used to regulate the air/fuel mixture, with the L screw adjusting the low-speed fuel mixture and the H screw adjusting the high-speed fuel mixture. Properly adjusting these screws ensures optimal performance and efficient operation of the blower.

The Stihl BG56 and BG86 are two different models of handheld leaf blowers. Here are the main differences between them:
1. Power: The BG56 is powered by a 2-stroke engine with a displacement of 27.2 cc, while the BG86 has a 2-stroke engine with a larger displacement of 27.2 cc. This means that the BG86 has slightly more power and may be able to generate higher air speeds.
2. Airspeed: The airspeed refers to the speed at which the blower can blow air. The BG56 has a maximum airspeed of 159 mph, while the BG86 has a higher maximum airspeed of 189 mph. This means that the BG86 can move air at a higher speed, potentially providing more efficient clearing of leaves and debris.
3. Weight: The weight of the blower can affect its maneuverability and ease of use. The BG56 weighs 9.3 lbs, while the BG86 weighs slightly more at 9.9 lbs. Although the difference in weight is not substantial, it could be a factor to consider if you prefer a lighter tool.
4. Price: Due to its slightly higher power and airspeed, the BG86 is typically priced higher than the BG56. The exact pricing may vary depending on location and specific retailers.
Overall, the main differences between the Stihl BG56 and BG86 lie in the engine displacement, airspeed, weight, and price. If you need a more powerful blower with higher airspeed, the BG86 might be a better choice for you. However, if you prioritize a lighter tool or have a smaller job to tackle, the BG56 could still offer sufficient performance.

The recommended gas ratio for the Stihl BG 86 is 50:1. This means you should mix 2.6 fluid ounces (77 ml) of 2-cycle engine oil with 1 gallon (3.8 liters) of gasoline.
