Gasoline cutting machine safety precautions? ? ? ? HQS500A gasoline cutting machine, 270MM road cutting machine, HQS-18 concrete pavement cutting machine, Lifan gasoline cutting machine, Honda road cutting machine, Eagle road cutting machine, diesel road cutting machine, cutting machine Shandong road gasoline use and safe road cutting machine ? Note 1, all parts should be checked before starting the bolts, nuts loose; check the direction arrow on the blade and blade guard arrows are the same. Inconsistency should be consistent tone. 2, you must check the tightness of the base gasoline engine, pulleys and other parts of the former gasoline engine starts. Check that the fuel system gasoline filling enough; check whether the lack of oil lubrication system. Traces of oil on the dipstick oil level should be the upper limit. Check the cooling system, heat sink, hood, debris on the fan, if the dirt has been cleaned to ensure proper cooling gasoline engine. 3, before turning the tank should be filled with water to cool the blade. Work, unscrew the pipe should be promptly switch blade like water, so that the blade cool. 4, the cutting depth adjustment by hand wheel. Handwheel lifting screw nut, so head height position changes, saw as the lift. 5, before cutting, the blade should be off the ground. After the blade is operating normally, can slowly rotate the hand wheel to head fall, when the saw cut to a predetermined depth, you can move forward, then the guide bar should first put down, the guide wheels touch the ground. ? 6 ,? cutting underway, eyes should be watching guide wheels, in order to grasp the direction of the slit; the guide wheel along a predetermined cutting line forward, cut sutures ensure linearity. 7, if traveling too fast, cut too deep or when experiencing high hard goods, machine overload and smoke, you should stop promoting, or slow feeding speed. Before 8 ,? machine stops, the blade should be cut off from the ground state. In the non-working state, non-blade ground to prevent or fight tooth blade deformation. 9, when the machine as a whole need to cross-cut pieces (such as the arrangement of the cement slab, slate, etc.) when it is, can be laid on a plate or angle to be cut into pieces, so that by the front and rear wheels on it.
