摘要：
A seawater powered band saw having a rigid frame or housing, a control handle and valve assembly having a trigger which when engaged by an operator delivers pressurized seawater to a seawater powered vane motor, a novel seawater lubricated spur and pinion gear drive arrangment connecting the vane motor in a driving relationship to a band saw drive wheel, an idler take-up assembly to tension the saw blade and facilitate the changing of saw blades and a safety guard assembly to protect the blade when the band saw is non-operational and protect the operator when the band saw is operational.
