CS Unitec CS 536664-3 20" Pneumatic Concrete Cutting Chain Saw Product Guide

This pneumatic concrete cutting chain saw is designed to provide precise and deep cutting capabilities in concrete and reinforced concrete environments. It addresses the challenge of creating square corners, deep plunge cuts, and mechanical openings that are difficult or impossible to achieve with traditional circular saws. The design supports cutting of irregular shapes and complex profiles on job sites where such detail is required.

In practical use, this type of pneumatic chain saw is well suited for contractors and rental customers needing to cut concrete, masonry, or reinforced concrete slabs and walls. It operates on compressed air at 124 CFM and 90 PSI, making it compatible with industrial air compressors commonly found on construction sites. The saw’s chain and bar setup allows for efficient removal of concrete during plunge cuts up to 20 inches deep. This helps streamline the workflow on site, avoiding multiple tool changes and enabling faster completion of detailed cutting tasks. Operators should monitor air supply and routing to avoid pressure drops that may affect cutting performance.

Where This Is Used

• Cutting deep plunge cuts and mechanical openings in concrete walls and slabs
• Creating square corners and irregular-shaped openings where circular saws or core drills are impractical
• Renovation, retrofit, and demolition projects requiring precise concrete cuts without engine fumes

Key Details

Selection Notes

From a selection standpoint, confirm that the job site has adequate air compressor capacity to supply 124 CFM at 90 PSI continuously to the saw. Check that air hoses and couplers match the saw's fittings and allow proper air flow without excessive pressure drop. For jobs requiring deep cuts or unusual shapes, the cutting depth and ability to make square corners make this tool a practical choice over circular saws. Consider the weight of 34 lbs with bar and chain when planning operator handling and access. Verify if a leverage accessory like a Wallwalker is needed to improve control and reduce operator fatigue during complex cuts. Also consider slurry and dust management plans since the saw will create concrete debris during cutting.

Post-Use Care Notes

After each use, thoroughly clean concrete slurry, dust, and debris from the chain, bar, coupling, and hose connections to support reliable operation. Inspect the diamond chain for wear and tension, allowing for adjustments or chain replacement as needed. The pneumatic motor should be kept free of moisture and particulates; if used in damp conditions, lubricate or flush per manufacturer instructions to prevent corrosion or sticking. Ensuring proper air-line moisture control with filters or dryers will help maintain tool life. Regular inspections and cleaning enable consistent cutting performance on subsequent jobs.
