Y19A Hand-hold and Air-leg Rock Drill 1,Instruction Y19A rock drill is mainly used in samll quarries,small coal mines and limestone mines for drilling,blasting for constructing roads in mountain areas,also in the capital construction for water conservancy works.it is suitable for drilling works in large mines for boulder blasting and other projects as well. When it is matched with air- leg model FT100,it can perform both dry and wet drilling under various kinds of rocks,and it is evenmore flexible in drilling operation when matched with the small- size compressor of capacity of 1.5m3,the function will be better than others. The flanged control vavle is adopted,so it has many advantages such as reasonable in structure,quick in starting ,light in weight ,fast drilling speed,lower air comsumption,smaller vibration,easier operation,lower trouble rate,long-life parts,good economic effect,ect.it is also equipped with a rubber damping handle,so is eary to operate and provide the operators with necessary working protection. 2,Specification Weight 19kg Outside dimensions(L×W×H) 600×534×157mm Cylinder dia 65mm Piston stroke 54mm Air pressure 0.4~0.5Mpa Air pipe inner dia 19mm Water pipe inner dia 13mm Shank dimension 22×108mm
When working pressure is 0.4Mpa 0.5Mpa Impact energy ≥28J ≥40 J Impact frequency ≥28Hz ≥35 Hz Idling speed ≥180 r/min ≥200 r/min Air consumption ≤37 L/s ≤43 L/s 3,Notice 1,This machine can perform both dry and wet drilling ,do not remove the water tube during operation,otherwise it will not work regularly and lose the function of normal blowing or centre water-jnjection,and slso damage the inner parts ,the function of normal blowing can be selected according to the working condition,when it is need ,remove the water pipe nut Y26-302F of blowing injection,and replace with a water pipe nut Y26-302S and a water injection hose Y26-303. 2,Before operating the machine,fill the oil tank of Model FY200A with lubricating oil.be careful if there is no oil in the oil tank. Operating without lubricating oil is not allowed. 3,When assemble the rubber handle,you should take care of the rear rubber ribs.the right handle is clockwise,and the left handle is counterclockwise.
