That looks EXTREMELY dangerous. Sawyer has little control of whee it goes. Lots of energy released quickly. Just hope that the sawyer is not in the way of it or whatever the sliding tree might pull down with it.
Ther is also a good alternative shown in the first referenced video to bore a square hole in the trunk and use a smaller limb in the hole to roll the tree.
Part of the hazard with this situation is in separating the stump from the trunk due to the tremendous tension in the trunk while it is...
I had a saw instructor/evaluator who accused me of falling tree wit a "pucker factor"... until he actually saw me cut. THen he offered me his fairly new MS440 to try out bucking.
This is where rigging can help immensely. You can use the rigging to force the trunk to go away from vertical. You...
Yes, I am "B-falling" certified. The district ranger gave us permission to remove that tree.
I didn't have much luck with videos. YT signal to noise ratio is pretty bad!
I don't know if the crown is well attached or not.
Correct. Getting to this point is my main concern as the tension near the base could create a barber chair hazard if the tree is not well hung and decides to come down.
Not so lucky with this one.
This works reasonably well until the tree...
That is probably a 12-16" tree. Not small for this area.
Unfortunately I have not laid eyes on this tree. All I have are the photos therefore I don't know who is hanging who.
Hello,
I am looking for some suggestions on the best practices for dealing with hung leaners such as the one shown in the photos. This one hanging over a hiking trail.
The situation is tricky as there is still significant tension/force from the root ball trying to stand the tree back up...
You can also set a search in Ebay and wait for a good used P&C to appear.
Feeler gauges should be thin enough to bend to the curvature of the cylinder. It's not perfect but should get you close.
Get out your bright lights and magnifying glasses and see if you can find a Makita logo or part...
I didn't really see any transfer in the photos. What you have is wear/damage caused by dirt ingestion.
.004" is probably about 2x what it should be new. Yes, it will run like this but the piston slap will rob power and accelerate skirt wear. Time to start looking for a spare top-end.
That is a...
.048" is large and likely the cause of somewhat low compression. What is the bore diameter of the cylinder? Others should reply on acceptable gap/bore dia. clearance
However, your gauge is suspect because the engine would not start/run at 80psi. Gauge MUST have a schrader valve at the tip that...
The outboard crank bearings are directly replaceable WITHOUT disassembling the crankshaft. However, if the big end bearing is shot you will need a new crank.
Another great upgrade is to replace the B&C with 3/8" LP like its smaller cousins use. You will likely have to also buy a new 3/8" LP sprocket or better yet a rim sprocket conversion kit. This should let it keep up with a MS260... almost.
If you pick up the saw nose up does it still stall? If not it is likely fuel pooling in the manifold. Raise the idle a bit and/or lean out the "L" slightly.
I just mount the carb in a vise (drill press vice) protected by some soft wood blocks. This keeps thing from moving around while you are trying to finagle the metering lever and spring into proper position.
