( 1 ) Only after the power unit is running smoothly can the drilling rig be started. Engage the clutch smoothly—avoid any sudden jolts; instead, do it gently, evenly, and with steady control.

( 2 ) External Drill Pipe Reminder: When shifting gears by moving the gearbox or transfer case lever, first disengage the clutch. Never attempt to shift gears while the vehicle is in motion. Only shift gears after the gear speeds have slowed down, to avoid damaging the gears.

( 3 ) Each gear shift should be fully engaged to prevent automatic slipping, which could damage the gears.

( 4 ) During operation, be sure to monitor the temperature of all moving components, such as bearings and gearboxes, ensuring it does not exceed the specified limit. 60°C If overheating occurs, stop the machine and inspect it.

( 5 ) External Drill Pipe I should also let you know: If the clutch is found to be overheating or slipping, stop the machine immediately for inspection and adjust the clearance between the clutch friction plates. Ensure the adjustment is properly set—too tight, and the clutch won’t engage; too loose, and the clutch will operate in a partially engaged state, leading to reduced torque transmission and rapid wear of the friction plates.

( 6 Before starting the drill rig and advancing into the hole, first lift the drill string off the bottom of the bore, then engage the clutch. Once the drill rig is running smoothly, gradually apply pressure to begin drilling.

( 7 ) When operating the lift, never depress both the left and right handles simultaneously, nor engage both handles and firmly apply the foot brake at the same time. Additionally, the winch should not be used to lift loads exceeding its rated capacity.

( 8 New drilling rigs or rigs that have been idle for an extended period should be started up before drilling begins. 2 Rapid operation 20min Only after all gears and bearings are evenly coated with lubricant can normal drilling proceed.

( 9 ) The drilling rig's locking mechanism must be engaged before starting the drill, External Drill Pipe Prevent the body from moving backward due to vibration.

( 10 ) The tachometer cannot be reversed. If the rotator needs to rotate in reverse, the tachometer’s flexible shaft should be removed first to prevent damage to the tachometer.
