Chainsaw Repair

Not that I know of.

The Makita is a top handled saw that some guys might like for use in the tree.  Only tried it at a tool show (indoors).  They generally make good stuff.  One cool feature is an option that lets you use (2) 18 Volt batteries, if you already have those for other Makita cordless, carpentry tools.

Only tried the STIHL 36V saw at a State Fair demo (a few times) cutting cookies from a 4" log in a saw buck.

As you noted, these saws also have different chains: mostly smaller pitch and shorter bars due to the power head.

The STIHL runs 1/4" pitch chain.  The Oregon saw runs 3/8" low profile (series 91) chain, but the pole saw runs 3/8" low profile, narrow kerf (series 90) chain. The Makita looks like it is also running series 90 chain. Don't know about the others.

The proof is in the cutting.  Trick with the Oregon saw is to let it do the work and don't try to push it.  Works well up to 6" green / 4" dry wood, although with patience, I have cut up to a 14" spruce with it.
