Wind-driven chain, according FLJ-400 pneumatic chain saws pneumatic chain saw chain saws Mine 400 chain saw wood cutting saw our well-developed wind-driven chain saw is mine roadway maintenance, special ideal tool for cutting wood. Suitable for coal mine gas production needs, the majority of users. Wind-driven chain saw to replace the manual knife sawing wood, both to reduce the people heavy physical labor, but also improves cutting speed. Replaces the past used electric saws to prevent the line work, more in line with the needs of production safety. Direct operation, simple. Wind convenient underground sources upwind tube to job security, free from the constraints explosion. Wind-driven chain saw model meaning: F --- pneumatic chain J ---- L ---- ---- chain chainsaw 400 Number of 400mm / min pneumatic chain saw instead of the manual knife sawing wood, wind-driven chain People saw only reduce the heavy physical labor, pneumatic chainsaw and improve cutting speed. Wind-driven chain saw instead of the past used electric saws, pneumatic chainsaw prevents live working, wind-driven chain saw more in line with the needs of production safety. Wind-driven chain saws operate direct, simple. Wind convenient underground sources upwind tube to job security, free from the constraints explosion.
