First, preparation before operation
1, saw blades, shell, handle without cracking, breakage.
2, cables, cords and plugs are intact, switch to normal, ensure correctconnections, solid and reliable.
3, saw blade installed, and bolt tightening, Chuck saw blade constrain both inside and outside. Blade plane and the horizontal axis perpendicular to thedirection of the electric circular saw.
4, check to ensure that the active protection cover flexible rotation, nodeformation, friction with the circular saw blade is not in, joining reliableguarantees in normal operation it will not fall off.
5, check to make sure cutting the workpiece firmly in place.
Second, operational considerations
1 when, startup electric circular saws must be in a vacant position, preventingelectric circular saw beat touch is when you start cutting the workpiece.
2, electric circular saw starts let it idle for some time, observe the saw bladeoperation is normal, whether the phenomenon of swing, electric circular saw isexcessive vibration, noise is normal.
3, electric circular saw where you must pay attention to its cable operations,prevent electric shock or short circuit fault caused by severed. Then access thepower behind cable to bypass the body do not contact with the cable.
When he was 4, circular sawing during cutting operation, fingers must not beclose to high-speed rotating body saw operator must be of appropriate distance from the device.
5, do not use circular saws in overhead locations, prevent circular saws orcutting off causing the accident.
6, a new saw blade is usually flat, open saw, sight distance needed to select 5¡æ ~20 ¡æ.
7, after the machine starts, it should transfer carriage for a while, check tomake sure machines flexible linkage unimpeded. When AB should be balanced andnot overexert.
8, never overload. Jobs should be paid attention to in audio and temperature,unusual should immediately stop checking. In the job too long, machinetemperature rise more than 60 ℃ or soups, or when there is a burning smell,should be shut down, jobs again after cooled down.
9, jobs may not touch the cutting tool and found it dull, damaged when abnormalsound, should immediately stop checking; repair or replacement of parts must becut off power, and wait for the saw blade completely stops.
10, saw blade blunt when filing requirements should turn off the power supply,pull the plug until the saw blade completely stops in order to remove the saw blade.
11, power outage, rest or leave the work site should power off the electriccircular saw.
12, processing is completed turn off the power, and equipment in and around thevenue clean.
