instruction:
"The machine 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.
