Question about Dewalt Saws

1 Answer

Saw won't always run.

Try to start the saw. The saw will sometimes slightly move...other times make a revolition...other times nothing and sometimes will even come on and stay on...and the cord must be unplugged to stop. Any ideas? Also the saw is starting to emit an odor. Brushes?

I think more than that, the switch sounds like the contacts are burnt but it could also be more major electrical. Give me the brand and model number and I will try and find a breakdown for you and give some more ideas. Let me know

Erratic starting circular saw


Sounds to me like you have a bad cord. Clamp the saw to a workbench so that it can start and run safely without you having to hold it. Put tape or a wire tie around the trigger to hold it in. THEN plug it in. Then move the cord around, especially near where it enters the saw. If the saw starts and stops intermittently you have confirmed the bad cord. Good luck.

Craftsman chain saw repair manual


Its not hard! You need to purchase a tool that goes into your spark plug hole. You remove the spark plug, put this tool in the hole. This tool stops the piston from moving so you can remove the nut holding the clutch. The clutch is what the drive sprocket is attached to. The drive sprocket is where the chain fits on at the engine side. remive the bar and chain and you will see the clutch. Use the tool and then use a wrench that fits the nut on the clutch. be sure you know which way removes the nut. It could be opposite of what you think. some are left hand threads some are not. I think these are not. After you replace the clutch be sure to lube the clutch bearings. Most people don't know this! use a grease gun made for saws and insert it into the hole at the end of the shaft that holds the clutch. Also next time your saw cant saw through a piece of wood, do not give it gas to make the chain try and move.This is what burns up the clutch! If your saw stalls out, and you press the throttle and it still doesn't turn. Always allow the chain to move, pull back and lift up on the saw slightly to get the chain moving again.

Carb ajustment


Only Info I see is "Homelite Chain Saws" - not much to go on.
Most saws have two carb adjustment screws, Hi, and Lo.
Assuming the saw will start and run enough to warm up, then
adjust the Lo screw in, clockwise, until the motor starts to slow down,
turn only about 1/8 turn at a time. From the point where it starts to slow down, turn it out about 1/4 turn. This should give you a decent idle. Now pull the throttle, and see what happens.
A - Saw runs up to speed, but dies off, or starts to slow on it's own.
turn Hi idle screw out about 1/4 turn.
B - Saw speeds up, but runs sluggish, fat - not real hi end.
Turn Hi screw IN, about 1/8 or so, and try again, or adjust
while running at full throttle. (best way)
IF it won't run well, try turning both screws all the way in to seat them, then come back out about 1-1/2 to 2 turns. this should get you in the ballpark to set things up as above.

Once the saw is running well, adjust the idle screw to a smooth idle but slow enough that the chain stops moving.

Stay safe

Skilsaw wormdrive stops working but if I wiggle the cord at the handle it sometime starts and will run until I take my finger off the trigger. Now it won't start at all even after wiggling the co


Replace the cord. Cords get internal breaks by the handle or boot because that's where they have the most bending movement. The wires break inside where you can't see them. When you wiggle the cord the connection is remade, usually with a spark hot enough to hold them together for a short time. When the saw turns off and the cord moves again the weak point breaks again. You can test this by pluggin in the cord and checking for voltage where the cord attaches to the switch.

My saw will start. It has always run quite well,


If it hums but doesn't turn it is almost certainly the starter capacitor which is fairly easy and cheap to replace . Usually a metal or plastic cylindrical object attached to the motor or sometimes inside the switch housing. Buy a replacement from Electronics store or from the makers of the machine.
If it does not hum and you have checked fuses then the switch is probably the trouble and switcheds dont like dusty environments at the best of times.

Mcculloch 3516 chain saw, does not always start.


It must have spark, fuel and compression to run. Your task is to figure out which is missing.
Sometimes electrical components quit operating once beyond a certain temperature. Does it always start cold and become tempermental when warm?
IMO most hard start problems on a chainsaw with a good fuel delivery system are flooded.
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4)
  4. Set compression release – optional step even if saw is equipped with a compression release
  5. Push (open) choke pull starter until it starts. (usually first pull)
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) - Don’t pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull)
The 3516 is a MTD McCulloch (Chinese). These saws are in a class by themselves. Good Luck

MK101 won't start


Can you move the blade with your hand or does the blade not move at all or is the sound buzzing even with the blade spinning cuz mostly this sounds like the blade is stuck and should be able to free it by moving it by hand unplugged all the debris from the tile dust can lock up the blades sometimes if it is not cleaned properly

Reciprocating saw stops reciprocating


your missing a tooth on a large round gear in the gearbox.

when the gear on the engine rotates into the position where the little engine gear spins because there is no tooth to come into contact with the engine runs but the gearbox doesnt spin, hence no reciprocation, but engine runs.

if you bump the blade it will start going again, but when you cut it will stop offasionally in mid cut. you can repair this but stop using it the engine gear will be destroyed otherwise

I have a dewalt dw303 that you can use for parts, I need a new trigger or something the motor is dead and I found a new saw. go to craigslist.org, rochester ny tools section and look for dewalt dw303 that is my listing. for ten bucks ill sell you all the gears you need. i think it is close to the same model, i am sure it is the same gearbox.

try opening your gearbox, im positive that is what is wrong.
