CS Unitec introduces a series of pneumatic chainsaws suited for use in underwater applications or in wet, hazardous environments. Series 5 1028 air saws are designed with a chain brake to stop chain movement during kickback or repositioning of the saw during cutting. These air saws feature two separate lubricating systems that automatically oil the saw chain and motor for easy startup and low-maintenance operation. Safer than gas or electric in hazardous atmospheres, these saws are suitable for use in hot work areas, Ex zones or hazardous environments.
