Redmax Backpack Blower common problems (EBZ7500,EBZ8500,EBZ8550)

Common problems we encounter with Redmax backpack blowers. Some of the issues are Redmax design issues and others are from abuse. This covers EBZ7500,EBZ8500 and EBZ8550 blowers.

[@testtesting2868]

My EBZ7100 is 17 years old. I ALWAYS used ethanol free 89 octane fuel with Mobil 1 2T synthetic 50/1 oil mixture. (I stocked up on this oil when it was discontinued in 2010.) Used approximately 20 hours a year (340 total hours). Replaced air, fuel filter and fuel lines once. Replaced spark plug every four years (80 hours). I run dry and fog the cylinder each winter when stored for 3-4 months. No carb work ever. GREAT machine!

[@hankhill5860]

I rebuild these all the time locktite all your engine screws and fan screws, put a tiny dab of silicone sealant at the end of the crank split case gasket where the cylinder gasket meets to be sure not leakage 👍

i have my original blower from 2013 many hours on it, did a top end two seasons ago and it runs great but sounds like its going to blow up lol. found out the fan spacers were all worn to hell. easy cheap fix and she will still be able to work as our back up blower

[@wallysworkin823]

Glad to hear. They had a problem with fans a few years ago where the metal inserts came loose. We replaced a lot of fans under warranty.

[@gplank2003]

I agree Amsoil sabor is the best.! Been using it for 3 years now. I mix it at 90 to 100 ratio like they recommended. I run all Amsoil oils in all my equipment and personal vehicles and love it.!

My dad bought a red max EBZ8001 on 2008. He used it for tree lawn care business until he stopped using on 2013 and he puts around 4 hours a day on it. Yes he does put it in full throttle all the time when he’s using it. He put approximately 980 to 990 hours per year and times that by five that’s around 5000 hours. Since he stopped using it. On 2013 which was 11 years ago, I’ve been using it every fall to clean up the yard. I put about 1 to 2 hours per year. I have additionally put on 22 hours per year and it’s still running to this day. I’ve ran a 45:1 to 50:1 oil gas mix. I Just have a question I have been wondering if they discontinued the EBZ8001 model? I haven’t seen Those red max models anywhere.

Thanks, more videos.

Looking for a video that breaks down the full blower and explains the components

My dad has a 7500 that worked like a charm for about two years, he's good at maintaining it as well he's not harsh with his equipment. All of a sudden it stopped turning on and about 10 pulls in it turned on accelerated completely for a bit then turned off almosr instantly, was wondering if that's a common issue and what the fix would be.

[@don1uan491]

Have a EB7000 that i bought brand new in 2000, run it everyday, changed carbs few times, starters, normal maintenance. Im starting to hear a crank noise or rattling sound on start up, not sure what it is but it runs good just want to see if anyone has encountered this? Wanna wait and see before i take to my mechanic since i can do minor repairs before i decide to go with him for major stuff...any OG's here?

[@DKSE123]

The ebz8500 unit I have here won't start . It has zero spark , also has 75psi ( dry) & 110 psi (wet) . Based on the compression , is it worth trying to save it? The coil has both wires ( for kill switch) & still has zero spark.

[@dustinshore1435]

I've had an issue with the engine flooding since I purchased it brand new. Fuel mix may spit out the exhaust when pulling the string. When mine actually starts and runs, it's is powerful... but I feel like I have a lemon.

[@wallysworkin823]

That is unusual for those units, the carburetors are very reliable. Sound like it could be warranty if you purchased from a Redmax dealer.

[@mattdaley1891]

Just picked up two 8550s they run one of them bogs down when i go full throttle... what do you think clean the carb

[@newcreation07]

The exhaust port on the cylinder has a problem with clogging up on the 8500 which I assume it has to do with the intake manifold and the cylinder head leaking

[@wallysworkin823]

That’s usually related to what kind of oil and gas mix someone is using. Cheap oil or a heavy mix ratio will cause carbon buildup.

[@wallysworkin823]

@@TheGameBoy56 I believe the factory specs are 70-75 inch pounds, been a long time since I’ve looked. I torque them 80-85 inch pounds. I have better results at this torque. You really don’t need to worry about it to much, use a good T27 T handle to tighten them up, just don’t go crazy. You do not need sealant on the gasket.

Hi i love you video quick question i got a redmax blower 8050 and a 8001 in they would not start new coil new carburetors in would not start help please

[@barbaraepsaro2718]

have you run into Flywheel notch problems wearing out on a newer blower? I'm in nj I've ran into this problem even on the trimmers

[@wallysworkin823]

No, never flywheel problems. I have seen problems with fans though.

[@leocastillo2222]

How can I remove the coil starter puller ? Is very hard ! Not the cover! The circle one is broke !😢

[@wallysworkin823]

Are you talking about the flywheel?

[@wildlotus06experience75]

Yea my 7500 is 10 years old. Easy maintenance. You gotta care about how you treat anything!

[@AB-coyote]

I want to buy a new Redmax Ebz8560 just for my House. Not commercial use. Any reason I should consider the Stihl BR800 or the Echo 9010 over the Redmax? Also I have non ethanol 87 easily available. Should I run octane booster or would I be better off running 93 with ethanol? It won’t be for commercial use but it will get used often as I use a blower to dry my cars after a wash so the fuel won’t sit in it for very long periods.

[@wallysworkin823]

Lately I am a fan of the 9010 but the Redmax is good also. You want to make sure and run 91-93 in either, both are prone to detonation. I prefer non ethanol but if you plan on using it frequently ethanol fuel will be fine.

[@AB-coyote]

@@wallysworkin823 same. I hate that there isn’t any higher octane non ethanol around here. Thanks.

Yes.

Hey walls working wats the best 2 cycle oil brand you recomend?

[@wallysworkin823]

Honestly any name brand oil is good, Echo, Stihl or Redmax. We also sell a lot of Kawasaki oil and for really good stuff we sell AMSOIL Saber.

What are your tips to keep these running forever?

[@wallysworkin823]

Good fuel, good oil, good maintenance. We have customers still running old EB7001’s, some are homeowners that bring them in once or twice a year for a check up.

Warranty is one year for commercial and don’t happen that in one year

[@coreybunss]

What octane should these use?

[@wallysworkin823]

91 or 92, whatever you have in your area. These blowers need good high octane fuel or they will detonate causing piston damage.

[@coreybunss]

@@wallysworkin823 we actually have 91 and 93

[@coreybunss]

@@wallysworkin823 is 93 octagon to high or would you say 91 is the safest bet from gas pump

[@nickflopper]

The two biggest ones i see you missed. The 2 lower engine mounts always break right off, and the choke levers break off every 3 days

[@wallysworkin823]

I didn’t mention the engine mounts because I don’t see that issue anymore. Years ago they fan and motor mount problems but that seems to be resolved. I did forget the choke levers too!

[@hankhill5860]

When you ever rebuild these use locktite on everything make sure to tighten to specs and they will never have an issue, always check your engine mount screws it's easy to remove and locktite

Ive got a brand new 7500 right now abd two weeks in starting to bog down at closer to full throttle, still havent got figured iut whats causing that.

[@wallysworkin823]

Make sure you run premium fuel, Redmax like high octane gas. It may just need a carb adjustment.
