The saw blades run very fast and to cut hard substances like concrete, a huge amount of friction is present due to which the blades often get heated up too much and for the proper maintenance of the blades, it is a good practice to periodically cool the blades. The concrete saw should be very carefully examined before use as it generates a lot of power in order to cut the substance and thus any minor fault in the machine can cause huge damage and prove to be dangerous to the operator. For safety use of the saw, following points must be kept in mind.
The drive pin hole on the saw should be free of any distortion, the core of the blade is made up of steel, thus it must be thoroughly ensured that the steel core is free of any cracks as the torque may prove the blade to slide out and be fatal to people nearby. The blades should be prevented from overheating and sometimes resulting from under-cooling as it may lead to irregular expansion of the blade metal and thus cause failure in cutting process as well as damage to the machine.
The orientation of the blades should also be ensured before the operation so that the blade is aligned for down cuts with the turning of shaft. It must be ensured that the diamond segments are properly oriented and none of them is missing. Operating the machine with missing segments can cause damage to the machine as well as the operator which might be fatal.
Some of the other precautions that should be followed to use this concrete cutter are as follows. The blade should be raise clear of the working surface before the engine is started and while turning it off, the cutting surface should be well clear off the blade to ensure protection of the operator.
