Farmmac f372w

Absolutely love the saw it is built very good I’ve ran a lot of chainsaws in my life from husqvarna to McCullouch to Stihl to holzfforma but the Farmmac f372w is beyond a fantastic saw if I was able to buy another chainsaw tomorrow it would be another Farmmac

Great saw for the money

I bought the f372 on Amazon and it is a good saw not a great saw. The oiler you could not adjust and would oil two tanks of oil to one tank of gas on the lowest setting. I ordered a aftermarket oil pump and installed it a the saw worked great. I ran about 5 tanks of gas through it cutting fire wood and the bar tip locked up and would not turn, I will have to put a bar tip on it now or a new bar before I can continue working. I did turn in the saw on the warranty that I purchased and got all my money back for the saw. I did put a new bar on the saw and chain on the saw and it still cuts wood well. I did like it enough to put the money towards the f660 made by the same manufacturer. Farmac or Neotec

Great quality wouldn't hesitate to buy again

Overall great quality I work on saws in my saw shop and I port them as well. I will be porting this one for a competition. But overall for any homeowner I would hesitate to buy comes with all the tools you need to work on it

Farmmac 372W

What a beast! Very impressed. Had to tighten a few bolts/screws. Fired on 3rd choked pull ran on 4th. Broke it in with 32:1. Very satisfying

This saw screams

I was very skeptical about buying a knockoff chainsaw, but decided to try. I do not regret it on this saw. Lots of power and will carry a 32inch bar with no problems. I run a 28 inch bar most of the time. I was so impressed with this saw that I purchased a second in the lessor model and a hop up kit to make it a 76.5cc chainsaw.

I purchased the lessor model of this saw and hopped it up and it screams as well. These saws will make a good landing saw for logging. But I prefer more lower end, more cc's, and more horse power for bucking bigger logs, so I purchased the G288xp and the 395xp made by the same company. I will update when I have them in hand.

Started right up instructions were spot on. The chain is junk. Had a new chain made up at the local chainsaw shop put a much better chain on works even better that's why I gave it five stars

Not what's advertised, but still a good saw

Was a more have a bit nervous about purchasing this saw. It didn't help much when it arrived without all the ' special ' pro parts that were advertised as beening on it. Didn't have a walbro carb or special cylinder and piston or Italian ignition, just your standard model farmmac clone saw. But since some other reviews and internet sites had warned buyers about this issue, my bad for assuming mine would be different. The gas caps had been tightened on so hard that the gaskets were permanently deformed. Plus the caps didn't appear to be the appropriate caps for this model to begin with, and after putting replacement gaskets on I learned they were indeed the wrong caps because you couldn't screw them in without the gaskets walking off. Ordered four different cap sets before I found one that works perfectly. You will need to check the important screws and licktite them before use. Did the 35:1 break in mix with ethanol free gas, and after the third pull on choke, it burped. Took it off choke and on the second pull, it came to life and ran and idled fine. I've cut up a 26in white pine and a section of a 30in black locust that has been dead for 5yrs, and it ripped though both with no troubles. Haven't run enough gas through it yet to switch to the standard 50:1 mix. After warming up it restarts in 2-5 pulls. By the way, the ' carbon fiber ' is fake. All in all, I'm disappointed by the deception, but pleased with how well it has run so far. If you need a saw to cut some big trees up with and don't mind using a saw that weights almost as much as a pull mower, then I recommend this saw. Time will tell how long this saw lasts. I will up date after some time, and more wood have been cut.

Great deal on a monster of a saw.

If you dont know if you need a saw of this size; then trust me, you dont. Runs like a top. But extremely heavy and miserable for limbing after the tree has been cut down. Ive run about 10 tanks of gas without issue. The blade is still sharp. For the money spent you just cant beat it for a saw of this size.

Amazing so far ...

I also have the Husqvarna 572xp that this is a clone of, it's a good saw but I've had some reliability issues with the auto adjusting carb and hard starting. I bought this saw so that when my husky was in the shop I could use all the bars and chains on this saw as my backup. I used it for the first time this Saturday for 5+ hours with a 28 inch bar and it cut all day. Refueled 4 times. It started with 2 -3 pulls every single time. The 28 inch bar with aggressive chain was a bit much for it when cutting through 20 inch logs, but the 24 inch bar went through very well. The husky has a bit more power but it was 4x the cost, for this price and the ease of use I would buy this saw again. Spend the extra few bucks and get the upgraded model with the good carb.

Easy starting

This saw has been fantastic to run. I've been presently impressed by it. All the power you need for larger trees. Not very heavy and easy starting. That's the best part.

FAQS

Cold Start
  1. Add fuel (fuel mixing ratio: 25:1).
  2. Close the choke. If the machine is equipped with a primer bulb, press it 3–5 times until the bulb is filled with fuel.
  3. Pull the starter rope 3–5 times.
  4. After hearing two “coughing” sounds,
  5. Open the choke.
  6. Pull the starter rope to start the machine.
Hot Start
  1. Open the choke.
  2. Pull the starter rope to start the machine.

The issue may be caused by an incorrect fuel mixture, spark plug problems, or a clogged carburetor.

  1. Check whether the fuel mixing ratio is 25:1. If not, adjust the fuel mixture to 25:1.
  2. Check whether the fuel line is bent or blocked.
  3. Check whether the spark plug is sparking properly.
  4. Check whether the engine is flooded.
  5. Check whether there is a carburetor malfunction.
  1. Confirm whether the spark plug is producing a spark: Remove the spark plug, connect it to the ignition coil, and place the spark plug electrode in contact with a metal part of the machine. Pull the starter rope and observe whether the spark plug produces a spark during starting.
  2. Check the electrode gap. The correct gap is 0.5–0.7 mm (approximately the thickness of a credit card).
  3. Clean oil residue and debris from the surface of the spark plug.
  4. If the engine still does not start after completing the above steps, replace the spark plug with a new one.
  5. Check whether the high-voltage wire (ignition coil lead) is damaged.
  1. Remove the spark plug.
  2. Turn the machine upside down.
  3. Pull the starter rope.
  4. Drain the excess fuel from the cylinder.
  1. Remove the air filter.
  2. Use an air blower to remove dust or debris from the air filter.
  3. If it cannot be cleaned or has been used for a long time, replace the air filter.
