Air-leg Rock Drill YT23

Air-leg Rock Drill  YT23

Instruction

The rock drill of YT23 is a kind of high efficiency air leg rock drill machinery. it is mainly used for blasting holes and other drilling works in a quarries, railway construction, water conservancy construction and defence project facility. When it is matched with the Model FY200A Oil reservior and Model FT160A or FT160B Air-leg, it can perform wet drilling and blast holes from different and angles.

Maintenance

Notice

1,Dismantle new machine and clean parts before using new machine, when assembling machine,

oil parts. then operate and check machine before using it, but the time is about 10minutes and air pressure is low (0.3Mpa for better).

2,The air pressure should be kept at 0.5-0.63 MPa.(measure in rubber tube), if the air pressure is too high, it will damage parts.if the air pressure is too low,it will affect the speed of drilling and machine normal working

3,Before using machine, blow off dirty to protect parts. inspect the screw thread whether is tight and operating handle whether is free to move, ensure machine operate normally.

4,Oil lubricating oil into oil lubricator before using machine, oil oil reservoir every other hour.Do not operate machine without lubricating oil.

5,Before using machine, increase holding power,while operate machine increasingly. Donot operate machine at the max thrust or should not idle machine too long, it will damage parts.

6,Diamantle water pipe and operate machine after blasting holes. It can blow off the rest moisture and protect parts away from rusting .

7,The rock drill is centre water-injection drilling. Do not operate without water and dismantle water needle.

8,Tighten two side bolt nuts to protect parts and tighten air pipe to aviod causing injure

9,If machine should store for a long time.diamantle machine first , oil and seal , then placed a dry place.

lubricating oil

Lubrication has great influence in the performance and working life. Do not operate machine without lubricating oil, it is better not to use grease lubrication to obstruct pipeline, reduce machine efficiency and acceleration element wear.

Please refer to following list when choose lubricant.

Safety

1,Ensure that technical safe practices are employed.

2,Pay attention to the position of steel wire ring clamp.

3,Check steel wire ring clamp whether or not abrase, if so, change another at once.

4,Do not allow ues low burning point and easy explosion lubricating oil.
