(1),Notice
1..Machine has been filled with the rustproof oil before using . It should be washed before operation and reassembled with lubrication.
2.The dunghill should be blowed before link the air pipe or water pipe to avoid parts from being broken by dunghill.
3.Before operating the maching should check whether all parts are credible. The oil reservior should be filled with lubrication and then adjust the oil capacity.
4.When finishing operation,cut off water supply firstly and then keep turning for a moment to blow off the rest water to prevent parts from rusting.
5.Maintain that using machine at intervals. It should be checked at least one time weekly to clear the dunghill and replace the broken or unusable parts.
6.If the used machine being conserved for a long time,it should be put into dry place after tooke apart and cleaned.
 (2),Lubiration
Lubricating will affect the capability and life-span of machine.Forbid to operate machine without lubrication and with lubricating grease to avoid degradeing efficiency and breaking parts.Please refer to following list:

Temperature	Name	No	Flash point(^0C)	Kinematic viscosity	Solidifying point	Standard
10-30ºC	Machine oil	N46	≥180ºC	41.4-50.6(40ºC)	-10ºC	GB443-84
-10-10ºC	Machine oil	N22	≥170ºC	19.8-24.2(40ºC)	-15ºC	GB443-84
-30-30ºC	Refrigerator oil	HD-13	≥160ºC	11-15(50ºC)	-40ºC	SY1213-79

(3).Aie pipe and pressure
1.Air pipe inner dia 25mm.To avoid loss of pipe pressure ,the length wii not excess 15 meters and the dia of pipe connector not less 19mm.
2.The work pressure is one of the direct influence for the drilling efficiency. Following figure is the relative curve between the speed and air pressure of YT24.The drilling speed increasing with the elevation of air pressure.The usual pressure is 0.4~0.63Mpa.
