Chainsaw Repair

Oregon .325 chisel chain has safety bumpers on every other driver that works along side the rakers.

Those small ramps are combined with quite small rakers - and the combination seem to be less in the way than the large ramped rakers of other designs like RS/RSC (and LG/LGX in 3/8").

LP/LPX is not compareble to Stihl and Carlton chains with ramps, as those retain the larger ramped rakers, as well as having larger ramps.

The LP design was meant to be a better alternative to the larger ramped rakers of LG and RS (as opposed to a "safer" one), and that is exactly what it is - at least as long as the bar length is within reason.
