Pneumatic Hand Hold Rock Drill Machine Drill Hammer For Small Hole
Most fit drilling horizontal and inclined blast holes in medium-hard rock with a hardness of f=8~18.
It may also be for making roof bolting holes. The drill is an important instrument in mining, railway, communication and water conservancy projects.
May be used together with FT160BC or FT160BD Air-leg and FY200B Line Oiler with transparent casing. The tool can also be mounted on a rig or a wagon.
YT28 fit for wet drilling in medium-hard or hard rock. Grouped control mechanism,quick to start up, with "air on ,water on, air off,water off" mechanism,convenient to handle and easy to maintain and repair. Energy-saving and efficient, long service life of parts, parts highly interchangeable and reliable performance. YT28 differs form similar products particularly in its high efficiency, strong flushing and powerful torque.
It can be matched with the FT140BD short air-leg or FT140B long air-leg to use in the basis of the width of rock. Also it can be fixed on drilling-vehicle or drilling-shelf.
Operation & maintenance:
Besides observance of the general safety precautions for rock drilling operations, particular attention should be paid to the following:
The rifle nut and the piston are matched with left-handed threads. Be careful with the direction of rotation during assembling and disassembling.
When connecting the drill to the air and water supplies, check carefully if the wire clips (32)(36) are entirely and correctly set in the respective semi-circular grooves of the backhead (30). Check frequently the wear on the clips and timely replace the worn-out or broken one or broken one to avoid the shooting out of the swivel(55)(58) or the connector when the air or water is on.
Before operation, fill the line oiler with lubrication oil up to the required level. The drill should not be run without proper lubrication (recommended lube oil N46 and N22, Chinese National Standard GB443-84).
After operation, first turn off the water, lightly run the drill for a few seconds, blow out the residual water drops to prevent the parts from being corroded.
If the drill is often used, should maintenance it regularly to ensure the inside parts cleaning. Especially pay attention to change the worn parts and lose efficient parts.
