What it is
The R300 Breaker cut-off saw (code R300) is a petrol disc cut-off saw designed for clean cuts in bricks, concrete and masonry on site. A professional tool for builders, bricklayers and construction firms who require precision and reliability on every job.
Asphalt and concrete cutting machines include floor saws, chain and track-mounted wall saws, cut-off saws and block saws with diamond blades and chains.
What it is for
Used for cutting building materials, from clay brick to concrete.
How to use it
Mark out the cutting line and make sure there are no embedded or buried services. Fit the diamond blade or chain suited to the material, checking the direction of rotation and tightening, and connect the water supply to cool the blade and suppress dust. Feed forward without forcing, letting the diamond do the work, and wear hearing protection, safety glasses and a dust mask. After use, clean the machine and the water circuit.
