Preparation before operating the internal combustion drilling machine

1. Installation of drill bit: 

Install a φ31 hollow drill bit according to the needs of on-site work. The specific method is as follows:

(1) Taking the installation of a φ31 hollow drill bit as an example, push the feed wrench to the end in the direction of the gasoline engine.

(2) Lift the clamp lever toward the gasoline engine.

(3) Lift the drilling machine, use a wrench or your fingers to loosen the set screw at the spindle sleeve, install the drill bit core into the drill bit, then align the two flat parts with the two set screws, and insert the sleeve. , and close it to the root of the spindle sleeve, then tighten the set screw to complete the installation. This machine is shipped with a φ31 hollow drill bit.

(4) Drill bit removal: Lift the drilling machine according to the steps (1) and (2) above, use a wrench to rotate the bolt counterclockwise, and take out the drill bit from the spindle sleeve.

2. Use of water injection bucket:

Align the handle with the groove at the mouth of the water injection bucket and press down to the root. Rotate the handle counterclockwise until the pressing device is unscrewed. Then add coolant into the water injection bucket (to prevent the drill bit and the drilled rail hole from rusting). After the coolant is full, tighten it clockwise, then rotate it counterclockwise at a small angle, take it out from the slot at the mouth of the water injection bucket, press the handle back and forth a few times (pressurize the bottom of the water injection bucket), and insert the water pipe into the fixture of the drilling machine. In the oil pipe, hold the handle of the water outlet valve of the water injection bucket, press the water valve downward with your thumb, and push it forward to open it. At this time, press down on the drill bit core and make sure the coolant flows out of the drill bit before proceeding to the next step.

3. Introduction and installation of positioning ruler:

This positioning ruler is divided into single-hole positioning ruler and double-hole positioning ruler. Each positioning ruler has three positioning grooves, which are processed according to the standard hole spacing of the rail.

Pull the ruler locator back and put the locator ruler into the clamp under the first groove.

4. Add fuel and lubricating oil:

Add fuel: Add engine oil and gasoline. First unscrew the fuel tank cap, add fuel inside, and then tighten the fuel tank cap.

Filling lubricating oil: first unscrew the oil tank cover of the lubrication chamber, add 20# gasoline engine oil in summer, and add -20# gasoline engine oil in winter, until it reaches the scale mark. Do not add less or more gasoline engine oil, and tighten it Fuel tank cap. Use your fingers to press the carburetor storage bubble of the gasoline engine a few times until the carburetor storage bubble is filled with gasoline.

5. Start the gasoline engine:

When the temperature is below 10°C, usually close the damper (lift it upward), increase the throttle to 1/4, quickly pull the start disk, and slowly put it back. After the gasoline engine starts, slowly open the damper to the maximum (press down), slowly increase the accelerator, run idling for 30 seconds, check whether the transmission part is flexible, whether there is any abnormal noise, whether the screw connection is loose, press the gasoline engine stop button, and prepare to drill.
