During operation of the concrete coring machine

 During operation concrete coring machine , mainly preparation, installation , drilling, drill , final hole five steps.
Preparation 1 , the use of pre-
( 1 ) adding 93 # unleaded gasoline and high oil, how much oil can be added to prevail based on the dipstick mark.
( 2 ) in the column filled with oil and turn the handle and feed the output shaft , check the feed and rotary is flexible and reliable.
( 3 ) ready for water.
( 4) Check all parts of the screw is loose.
2, the installation
Drill holes later on , the three  concrete saw blades walking round lifting , so the base fell to the ground. Hit the hole and concrete strength is not high , then you can rely on its own weight rig rig fixed , if playing a larger aperture , the rig can not hold their own weight when the rig can place heavy objects ( such as sand bags on the chassis, iron , concrete blocks , etc. ) fixed or play two bolts plus bar ( such as channel , etc. ) to secure the rig , rig securely fixed to not shake , otherwise not normal drilling operations .
3 , opening
After doing these jobs , job openings can , put on the drill , the starting gasoline engine (see gasoline user manual ) of the inlet pipe into the bucket, the bucket to mention higher pump position, and  grinding cup wheels then pinching the water suction gas -hsiang pumps, water pumps , Sheung Shui, the bucket on the ground level . Throttle to maximum and began to jiggle the handle into the drill slowly touch the ground. Opening Tip: after the first water drilling, feed slowly, WOB small. Prohibited anhydrous job , it would burn the drill and seal .
4 , drill
When 2-3 mm deep hole drilling , the drilling can be turned into a normal , appropriate at this time to increase the  feed pressure , normal drilling tips : feed pressure should be moderate , to maintain uniformity , crude steel to encounter to reduce the intake pressure . To do listen second look , whether listening to the sound of the machine  diamond cutting tools properly, to see whether the return orifice ( risk ) of water.
5 , final hole
After reaching a depth taken , you can stop drilling . Stop drilling requirements are: first turn off the water after the machine when if deep , can not immediately provide drilling and without water , while punching with water for some time, aimed at the hole in the rock powder rinse to prevent rock powder precipitation resulted in burying cause coring difficulties.
