Cutting beach wood Alaska style, we use a portable gas powerd pressure washer and a water pump, we pressure wash the silt off them black spruce logs.
we use a Sthil but swapped the 20" for a 16", set the poiler to max, some fellas use a 5 gal bucket of oil and dip the bar & chain (power oil)
still end up ruining a pair of bars and several chains a season.
