Easy to follow and thorough step by step tutorials do it yourself (DIY) videos to help you with your broken lawn and garden equipment including snowblowers and zero turn mowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed wacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, zero turn mower, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.
I have the largest Small Engine Repair Video Library on RUclips and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!
I want "DON THE SMALL ENGINE DOCTOR" on RUclips to save you time, frustration and most importantly, MONEY with my HOW-TO videos!

good advice, one thing to remember though is to always blow your saw with the filter in place so you do not fill up your intake with the very same dust we are trying to keep out
Donyboy! Man, I have yet to come across a concrete saw that hasn't been beat to heck. They truly run in the worst conditions of any small engine. Thanks for the video!
You got that right!
need to use water keeps the dust down keeps the blade cool and lubricated and the operator isnt breathing in the dust
I’ve Rebuilt Many Of These Over The Years TS760’s TS350’s TS400’s TS420’s and The TS700&800 Series Great Saws Every One Of Them They Live in a Harsh Tough Brutal Environment and Maintenance is a Must 😀😊
Husqvarna recommends not replacing air filter until loss of power blowing it out can make air filter pores bigger and let more stuff through, just what I was told
I still throw a new filter on every chance I get though lol
I just finished putting an entire new Chinese engine in the same saw that a concrete finisher had completely destroyed. This is probably the most complex machine I have ever rebuilt, complete with a decompression valve. Just got I running and a new air filter arrives today.
Wow no maintenance !! That wasn't just dirt, that was like "valve grinding compound" .
Great Video. Thanks
Great point!
Yeah! You are soooo right. I was @the Post Office today and saw a Wanted Poster Picture of the same filthy filter with the caption below.. 'Repair Shop Public Enemy # 1'... Approach with extreme caution'
..'May be accompanied by naive saw operator' .. 'Dispose of on sight'
As a Forman of a crew running these on pavers all the time my rule was roughly 8hours of run time change the filter. These saws are the life blood of most interlock jobs so you need them running well. Good video but also what I’ve noticed myself is the older carb, primer and choke style saws perform 100x better than the new fuel injected saws when it comes to cutting stone without water.
I definitely agree!
If the user has access to water, running the concrete saw with water hooked up will really help with keeping the dust down. Ideally having 2 or 3 air filters and cleaning and changing them daily during heavy use is the best. I have heard of brand new concrete saws being "dusted down" and ruined in less than a month. These saws cost $1200 in U.S.
The only problem with running the water is that it stains everything but you can maybe cut somewhere that doesn’t matter if it’s stained like dirt or something
Con saws live a very tough life. Most of the time people dont let them warm up either. As soon as it starts itll get full throttle. Amazing that they last as long as they do tbh
Hi Don and other commentators. From first hand I know that the filtration system of the STIHL cut-off machines is engineered for tough conditions and low maintenance. Low maintenance meaning that the air filter needs to be changed only when the cutting performance is reduced. It is actually not good to change the filter too often, even if that makes sense at first and is normal practice in f.e. chainsaws. The carb also (as in lots of other STIHL machines) has a compensator which keeps engine performance and fuel/air-ratio constant even when the air filter gets more and more clogged.
Nice video👍 clear and concise.
Hi Donyboy you are right the dust in the filter and watching people using the saws with no masks. Not good for the lungs keep up the good work.
Agreed! Can’t tell you how many ts700 800 I’ve rebuilt. If a crank bearing was bad then we deemed it DOA
Just shows how good the filters are.
Good information 👍.
This applies to all concrete saws i have come across... Hilti, Makita, and Husqvarna. Thanks for the video. =)
WOW A lotta dust. Thanks, DB73 Great heads up for saw owners. God Bless !!.
yes sir had one last week loaded with concrete dust and it looked like some body used sand paper in the cylinder destroyed thanks for vidja dony
That’s a lot of dust, very good advice again 👍👏👏
Use water when cutting.
A clogged air filter will run rich and ultimately cost you more than the time to clean it.
I carry a gas powered air compressor and after cutting I blow all filter engine creaves until no more dust end of the day new filter long distance change maybe twice
where the garden hose hooks up it always plugs first 2 seconds
wow
I Also Advise Using The Water Port Too Keep The Dust Down and Out of The Saw and Operator’s Lungs 😀
Please make a video in adjustment of carburator (H,L,LA). My cutting wheel keeps spinning.
I would bet a donut that the operator isn't the owner. When someone has to buy the equipment themselves, there is a bit more of an incentive to take care of it.
Good day Don Wow I have serious inherited asthma, I can't change my filters like that. Thanks
A big ouch there Donny mate.
In your opinion, do you think having the water line hooked up and used consistently every time totally mitigate that dust problem? Or just partially?
I'm not a mason, but I couldn't help myself when our mason subcontractor threw 3 Stihl and 1 Hilti concrete saws into our dumpster. I sold the Hilti as is, and I'm getting 120 and 130 psi from 2 of the Stihls, but I'm still wondering if I should just totally rebuild at least one of them...
Wow! And you would have paid for those saws on your bill! There really are some lazy, dirty, couldn't-care-less bastards around.
100% Don, never loan one of these, people just don't look after them. I have had a few of these in for cylinder kits as you can imagine
Great video right now I'm working on one of those saws I just replaced the air filter spark plug clean the carburetor and I can't get it to run any other advice please
Air leak-seals or hoses,no spark-bad coil,dirty fuel,/fuel tank, flywheel-coil gap not right
@@hankthebugman why ditch it? It can be sorted
👍👍👍
can you blow out the air filter to clean it or should you replace it all together?
You shouldn’t blow out a paper filter, it can expand the openings and allow bigger/more particles through the element. I always just threw a new one in, for what they’re worth it’s cheap insurance.
Many workers take filters off to spray starting fluid .
I make sure that it's never taken off . Security screws.
Wow! That's crazy. Fire those guys.
@@thomasmagiera3283 no comprende ...only Latinos work anymore
Just think most people people who run a saw like that probably have the dust in their lungs too. I see so many people cutting with these with no dust mask or water hooked up.
Holly Hell?!! That's one dirty demo Saw!! I see Money!! And more money made!!!
Oh man!
I hope you were wearing a dust mask while blowing the dust off the saw!
(and what the heck, might as well throw some safety glasses on while you're at it).
Yikes. I am off to buy a new filter, hope they come in bulk
You might check with Cutters Choice. They sell a lot of air filters & other misc.
Thank you. Service manual or shop manual priceless. Your videos over the years much appreciated. God blesd
Do humans have air filters? Do humans have replaceable air filters🤔🤔🤔
Yes. We have nose hair. Unfortunately we can't replace lungs that easily and like concrete cut off saws, we die. You're so right though when you see people using this kind of stuff, squinting their eyes and holding their breath.
They didn't hook-up a water hose ???
Fuck that what do my lungs look like
You do not need to replace the filter EVERY week!?!
If you run a TS410 you need to get yourself a good old fashioned compressor with an air gun.
Not only to blow out the filter (tap as much out first) but also to blow out those air inlets to the left hand side of the housing.
Clean filters won't help if your machine can't breath.
It's a crappy design, buy a husqvarna instead
(once your upper right spring mount breaks off)
Man we usto use these cut off saws like Thay were disposable lol . Time is money The tools are cheap compared to the time paying 10 union guys weighing around for something to be cut . The cost of all the new tools was just included as a part of the final bid .lots of guys would score tools when it came to the end of the jobs
This was the reply I was about to make. Laborers do not care about maintaining equipment, they are there to get paid. Larger construction companies include tools like this in their bids, they are in fact expendable. Gotta have the tools to do the job...
@@terrymassey7619 that is a fact I usto cringe at the stuff I was asked to put a tool threw like cutting up root balls with rocks and using a new saw but a you get usto just abusing stuff in the name of getting the road built or the runway finished my old boss sold his company but he still has piles of crap in his old work yard lol but I definitely baby my own stuff compared to work tools
Stihl says to change the filter every 6-12 months, don’t bother clean it. To change it every week sounds like overkill
Do the electric ones get like this? If there *are* cordless electric ones, that is.
no they don't
Anything with a motor that draws in concrete dust is going to be worse off until it causes self destruction prematurely. Most cordless tools I'm aware of, have motors that pull air through themselves for cooling. It may not happen as fast but keeping this grit off any moving mechanisms (besides a cutting blade/disc/etc, obviously) is worthwhile.
@@stinkycheese804 for sure. The only thing is, I've never seen an air intake filter for an electric motor on a power tool. Maybe a little screen and that's it.
I can imagine the operator not wearing a mask while using it probably can't breath when done so screw the saw, I need freah air.
Probably needs changed before starting. So have 4-5 on hand.
Imagine the operators lungs? Would water on the blade as it cuts help? Oversized Shop Vac duct taped on the operators shoe?
Water would help keep the dust from becoming airborne.
personally would def be wearing a p100 respirator like an ff400 with 7903 filters
@@viewer54322 Man why can they not produce or have a solar wind powered Swiss Army Dust Sucking Laser that cuts clean and Donny can fix via Alexa. J/K guys come on
I would have thought is was caused by apprentices trying to "bump start" them! 😂
It should not be used without water cooling the blade.
I hate workin on them.I tell my customers to keep air filter clean and carry spares.
Filters are cheap. The saw is about $2000- Easy math.
I don't agree. The worst thing is to use non genuine air filters. Plus a new air filter is not as efficient as an older one.
That dust is likely full of silica and will also fill up your lungs! The device can be replaced. Do it for your lungs, first!
wet cut every time
Were u born in 1973?
Concrete dust is a recognized cancer causing agent due to the silica being ground into a flour consistency as well as other mineral compounds in the aggregate and the CEMENT POWDER in the concrete. The dust is very corrosive (pH of 12 to 13). On big grinding jobs the slurry must be captured and properly disposed of because it would kill everything it touches on the ground. Look at an old bricklayers hands the skin is eroded back on the hands. As others noted the use of water to protect the OPERATOR is a given as well as the equipment. I cringe ever time I drive by a job and see a worker using a concrete saw with dust floating all around him and onto others. A useful experiment would be to weigh a filter before and after a big cut job. These are basic health and safety regulations in every province. Good topic for your viewers. Look up the illness called silicosis to check it out.
Ain’t that just common sense from the user?
should be!
Maybe but consider a situation where the user isn't the tool owner and doesn't want to bother or isn't aware of how important this is. Many people will just continue using a tool until it stops running.
@@stinkycheese804 Yes Stinky, there are some like that right!
