2-Cycle Backpack Blower is rated 4.428571428571429 out of 5 by 49.
Rated 5 out of 5 by from Light weight yet powerful I have just received this and have only used once but love it! I am 5'1 and my husbands backpack blower was too heavy for me to use so I was stuck using an electric one. Because we have a large yard I was only able to reach a small area. The Ryobi is so light weight and easy to start! I had a blast blowing leaves which use to be a dreaded chore! I would definitely recommend this blower.

Rated 5 out of 5 by from I love this blower! I got this blower for Christmas from Mrs. Claus. It is so light and powerful. I added a strap to hold the wire harness to the throttle handle to streamline the blower arm. I blow my one acre yard, sidewalks, decks, and driveway in less than half an hour on half a tank. Thanks for the great recommendation from The Home Depot.

Rated 3 out of 5 by from Good for a few months I'm on my third one of these blowers, they work great for a few months and then they start to bog down and die then a pain to restart. Think I will go with a different manufacturer for my next one.
Date published: 2016-09-23
Rated 4 out of 5 by from Works like a charm This unit starts easily and handles well. Lots of air flow gets the debris moving and I like the speed lock. The ring securing the hose to the housing is not strong enough and broke quickly, so I replaced it with a stainless steel clamp and all is well again. I like the anti-vibration mount too.

Rated 3 out of 5 by from Occasionally hard to start Nice blower. Gets the job done. So nice not lugging the electric cord along. Occasionally is very hard to start, .... just keep trying. I'm a small frame; straps don't tighten enough to securely wear. This makes it awkward to use. Overall a good purchase.

Rated 4 out of 5 by from This was second unit. First had difficulty maintaining adjustment and thus difficult to start. Home Depot and one independent repair facility could not fix even with new carb. Had replaced and have used only pre mixed girl and it has worked flawlessly.
Date published: 2016-04-28
Rated 5 out of 5 by from Great power and well made This back pack blower is extremely well made, started first try right out of the box and has excellent blowing force. I've had several others and I put this right up there with those that were much more expensive. Excellent tool

Rated 4 out of 5 by from Life is easier Got my blower for Christmas. Had used an electric blower before. What a great change. Flexible, convenient, and good power. And no cord. Had to have the timing tweaked by their service people, then worked great! Life us easier!!

Rated 5 out of 5 by from Great Power After owning a handheld 32cc blower I was amazed at how much power this blower has. The ease of a backpack makes a huge difference as well. The unit has everything I need, power, comfort, ease of start. I wish I had one sooner
Date published: 2016-06-07
Rated 5 out of 5 by from What Power! I've had my blower for over a year now and absolutely love it. It starts easy, fits on my 73 yr old back comfortably, and is loaded with power. What used to take a full day with my electric blower I can do now in 3-4 hours.
Date published: 2016-04-28
Rated 4 out of 5 by from Solid product for the price I bought this about a year ago and it's been really good. Starts easily and has good power. I've used many other blowers (including echo and red max) and while this isn't the best blower, it's really pretty good.
Date published: 2016-04-18
Rated 5 out of 5 by from Light weight, Performance, and ease of use. I went online and came across a review, and a demo for this. That and the price, I went to the Home Depot and checked it out. I was impressed then and after using it, I am totally impressed and happy with it.
Date published: 2016-04-18
Rated 4 out of 5 by from Good product with good value. Really happy with the purchase, more than enough power for the size of my yard. Good price value. If I had to find a drawback, it is that the unit sits a little low on my back, even with adjustments.
Date published: 2016-09-18
Rated 5 out of 5 by from Starts on the first pull I received my backpack blower for Christmas and it has been a wonderful addition to my yard tools. It starts on the first pull and has amazing power. I would definitely recommend this to a friend
Date published: 2016-04-28
Rated 5 out of 5 by from Great Power, Starts easily Purchased for Fall Clean*up. It worked great. Put leaves where I wanted effortlessly. My Only suggestion would be to have the Blower ride up more on shoulders rather than on your hips.
Date published: 2016-04-18
Rated 3 out of 5 by from It's okay Bought this about a year ago and it works okay, could be stronger. The momentary switch (kill switch) no longer works and I haven't found one locally so I order online from Amazon.
Date published: 2016-04-28
Rated 5 out of 5 by from Starts every time Had this blower for about 6 months now, starts up on the first crank every time. This is a well invested buy for a homeowner with about 1 acre. you won't regret it.
Date published: 2016-04-18
Rated 5 out of 5 by from Light weight! I'm a disabled veteran and by this blower being light weight and easy to maneuver, it allows me to get back outside again! And it's very powerful for it's size!
Date published: 2016-04-18

What is the correct fuel mixture to use with my 2 cycle engine RYOBI Outdoor Product?

Your 2-cycle engine requires pre-mixing gasoline and 2-cycle lubricant. Pre-mix unleaded gasoline and 2-cycle engine lubricant in a clean gas container. DO NOT mix quantities larger than usable in a 30-day period. Do not use automotive lubricant or 2-cycle outboard lubricant. We recommend using a RYOBI/Homelite premium 2-cycle oil or a PowerCare 2-cycle oil.

Filling your tank:

  • Clean surface around fuel cap to prevent contamination
  • Loosen fuel cap slowly. Rest the cap on a clean surface.
  • Carefully pour fuel into the tank. Avoid spillage.
  • Prior to replacing the fuel cap, clean around the gasket.
  • Immediately replace fuel cap and hand tighten. Wipe up any fuel spillage

Note: it is normal for smoke to be emitted from a new engine after fist use.

  • Place a large tube clamp onto the outer slot of the upper (wider) end of the bellows
  • Attach upper end of bellows onto blower housing by sliding it over the air outlet

  • Tighten the large tube clamp using the assembly tool and place a tube clamp on other end of bellows
  • Then press bellows onto throttle control handle tube and tighten the small tube clamp using the assembly tool

NOTE: The position of the throttle control handle may be adjusted for comfort after the blower is strapped onto the operator’s back

  • Join the straight tube and nozzle together by aligning raised locking tabs on straight tube with the raised locking slots on nozzle and twist to secure
  • Assemble the connected lower tubes to the throttle control handle tube by aligning raised locking tabs on the throttle control handle tube with the raised locking slots on connected lower tubes by twisting to secure
