Operation and maintenance: Besides observance to the general safety precautions for rock drilling operations, the following points must be adhered to: ● When connecting the drill to the air supplies, check carefully if the wire clip (52) which

combines the air pipe swivel (53) with the back head (35) is entirely and correctly set in the semi-circular groove in the back head, check frequently the wear on the clip (52), timely replace the worn out one.

● The part (1),(2) and (3) of the distribution valve assembly should be assembled and disassembled with great care to make sure that no burrs will appear through pushing and striking. After reassembling, shake gently the valve assembly to see if the valve (2) can nimbly move to the end positions in the valve chest (3).

● The rifle nut (8) and the position (9) are left-hand threaded. Cautions should be taken during assembling and disassembling.

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 ad disassembling. ● When connecting the drill to the air and water supplies, check carefully if the wire clip(32)

(36) are entirely and correctly set in the semi-circular grooves in the backhead (30). Check frequently the wear on the clips, timely replace the worn out or broken one, so as to avoid the shooting out of the swivel or the connector when the air or water is on.

● Before operation, fill the line oiler with 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.

Applications: ● Most fit for drilling horizontal and inclined blast-holes in medium-hard and hard rock with

a hardness of f8-18. It may also be used 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.

Features: ● Grouped control mechanism, quick of start up, with “air-on, water-on, air-off, water-off”

mechanism easy to handle and maintain. ● Low noise, small vibration, energy-saving and efficient, highly interchangeable parts with

long service life, reliable performance. ● Different from similar products particularly in its high efficiency, strong flushing and

powerful torque.

Operation & Maintenance: Besides observance of the general safety precautions for rock drilling operations, the following points should be attended to: ● The rifle nut and the piston left-hand threaded. Caution should be taken during assembling

and disassembling. ● Before connecting the drill to the air and water supplies, check carefully if the wire

clips(37) (43) are entirely and correctly set in the respective semi-circular grooves of the backhead(29). Check frequently the wear on the clips and timely replace out of the swivel or the connector when the air or water is on.

● Before operation, fill the line oiler with lubrication oil to the required level. The drill should not word without lubrication oil(recommended lube oil N46 and N22, Chinese National Standard GB443-84).

● After operation, first turn off the water, run the drill lightly for a few seconds, blow out the residual water drops to prevent the parts from being corroded.
