（1) The drilling rig can only be started after the power machine operates normally. Engage the clutch smoothly.,No impact is allowed, and it must be light, uniform and stable.

（2）water well drill pipeWhen shifting the gearbox or transfer case handle, the clutch must be disengaged first. It is strictly forbidden to drive the gear. The gear can be shifted only after the gear speed slows down to avoid damaging the gear.

（3) Each gear shift should be completely full to avoid damage to the gear by automatic sliding gear.

（4) Pay attention to check the running parts during operation, such as bearings, gear boxes, etc. The temperature shall not exceed60 ℃If overheating, stop the machine for inspection.

（5) If the clutch is found to be hot or slipping, stop the machine for inspection and adjust the clearance of the clutch friction plate. Gap adjustment shall be appropriate. If it is too tight, the clutch will not be engaged; if it is too loose, the clutch will work in a semi-clutch state, which will cause the transmission torque to decrease and the friction plate to wear quickly.

（6) Before starting the drilling rig, the drilling tool should be lifted off the bottom of the hole, then the clutch should be closed, and the pressure drilling should be carried out after the drilling rig operates normally.

（7）water well drill pipeRigWhen using the elevator, it is forbidden to press down the left and right handles at the same time, or tighten the handle combined with the foot brake at the same time; the hoist should not be overloaded.

（8) New drilling rigs or drilling rigs that have been stopped for a long time shall be started before drilling.2Minimum speed operation20 minNormal drilling can only be carried out after each gear and bearing is splashed with lubricating oil.

（9) Before start-up, the locking device of the drilling rig shall be locked to prevent the machine body from receding due to vibration.

（10) The tachometer cannot be reversed. If the gyrator needs to be reversed, the flexible shaft of the tachometer should be removed to avoid damage to the tachometer.

（11) In the process of drilling and lifting, do not pull the drill to move the handle.

（12）water well drill pipeIn case of abnormal noise during the operation of the drilling rig, stop the machine to find out the cause and eliminate it.

（13) In the case of automatic brake, the operator shall not leave, and if necessary, the pawl shall be used to jam the cam.

（14) The holding brake belt shall not be splashed with oil to avoid slipping.

（15) All hydraulic control handles cannot be used at the same time; after the gear oil pump is started, pay attention to the response of the oil pressure gauge and the hole bottom pressure indicator. During the drilling process, when the pressure at the bottom of the hole needs to be increased or decreased, it should be adjusted gradually without sudden increase or decrease. When the vertical shaft (fast reverse rod) is quickly lifted by the oil pressure system, it is only allowed to be carried out under the original load to prevent damage to the machine parts.

（164) In order to reasonably use the hydraulic system and ensure safe operation, the various states and working pressure values of each actuator shall be within the required range.

（17) Winch"Water cooling”After the end of use, the water should be drained and the rubber water seal should be removed and coated with lubricating oil to prevent parts from rusting or freezing the reel.

（182) Before the rig moves backward, pay attention to untiewater well drill pipeLocking device for drilling rig.

（194) When the drilling rig is not used for a long time, all exposed parts shall be coated with lubricating grease to prevent rust.
