The Stihl SR 450 Mist Blower, manufactured by Stihl, is a professional-grade backpack sprayer and duster that can hold 3.7 gallons of liquid and solid insecticides, fertilizers, herbicides, and other granular applications.

Stihl SR 450 Mist Blower is a two-in-one conversation mechanism for dusting and spraying granules that helps with exact measuring for dust metering. It features a more powerful engine that allows for a 20% greater spray range than previous models. 

It is ideal for distributing liquid and solid products, and the Stihl SR 450 mist blower can easily be converted into misting or dusting treatments without any additional tools or equipment. The airspeed can easily be fixed for greater application, and this product can also be used as a powerful leaf blower for debris cleanup.

Tools Needed

To use this blower, you only need your choice of insecticide liquid to mix into the sprayer tank, trash bags for waste cleanup, and the appropriate personal protective equipment (PPE) to protect your face, eyes, mouth, hands, and feet.

How to Use

Applying Mist Blower Backpack Sprayer

  • Step 1: Determine how much fertilizer, herbicide, or insecticide you must apply in the Stihl SR 450 mist blower. The tank can hold 3 gallons of product. Depending on the size of your property or treatment area, target pests and the insecticide you use may require more than one application.
  • Step 2: Twist the cap off the tank and fill it halfway with water. After it is halfway filled, take your product of choice and pour it into the tank according to the product's application rates.
  • Step 3: Agitate the unit and then top off the tank the rest of the way with water required for proper mix. 
  • Step 4: To start the engine, set the setting level to one and press the manual fuel pump bulb at least five times. Securely place the unit on the ground and pull the starter grip. Do not jerk it, or else you may break the string or the inner controls. The pull should be slow and smooth, unlike lawn mowers, which require a strong jerking pull.
  • Step 5: Place the Stihl SR 450 mist blower onto your back and adjust the sprayer to the right setting before applying the spray to the target areas. When finished, power the sprayer down and store it in a cool, dry place.

Where to Use

The Stihl SR 450 mist blower should be used outdoors around your yard, residential home, landscapes, greenhouses, and commercial buildings to control mosquitoes, flies, and other pests.

When to Use

Keith's Pro Tips"When using the leaf blower function, remember that this can backfire. When you're blowing away the debris on the ground, you are also blowing all things on the ground where you are spraying, including debris like glass shards, leftover nails or screws in your yard, and so on. This is why you should minimize the blower's power when blowing with the leaf blower. Not only are you keeping other people near you safe, but you are also having easier control over the blower."
Product DrawbacksThe SR 450 Mist Blower needs regular upkeep to maintain peak performance. This product may be noisy and could disturb your neighbors when applied in a residential neighborhood.
