FAQs

Q: How do you pump a STIHL SG 51 backpack sprayer?

A: To operate the manual STIHL SG 51 backpack sprayer, use the side-mounted pump handle. Move the lever up and down to build internal pressure in the tank, allowing you to spray evenly across your garden or work area.

Q: How far can the STIHL SG 51 backpack sprayer spray?

A: The spray range of a manual backpack sprayer like the SG 51 can reach up to 4.5 metres. For best results, always spray with the wind at your back to reduce drift, especially when applying herbicides, pesticides, or liquid fertilisers.

Q: How does a manual backpack pressure sprayer work?

A: A backpack pressure sprayer like the STIHL SG 51 uses a manual pump mechanism to create pressure inside the tank. Once pressurised, liquid is dispensed through the nozzle when the trigger is pulled, offering controlled and precise application of the contents.

Q: What is the typical lifespan of a backpack sprayer?

A: The lifespan of a backpack sprayer depends on several factors, including build quality, frequency of use, chemical exposure, and maintenance. With proper care and regular cleaning, a high-quality sprayer like the STIHL SG 51 can last 5 years or more.
