HOW TO USE OH-01
1. To absorb shocks from spinning, it is advisory to prepare an optional hock absorber for supporting operating.
2. Connect earth drill and power source with extension hoses.
3. Attach auger and extensions to the earth drill.
For snap-in type attachment, make sure all the joints are locked firmly.
4. Connect a shock absorber with power pack.
5. Start the power source.
6. Hold the handles on earth drill firmly.
Stick the front of the auger in to determine the drilling position.
Grip the control lever on the longer side of the handles, auger will start spinning in the normal direction.
Slide the earth drill toward the body.
< WARNING >
DO NOT grip the control lever if auger has not been stuck in the ground.
7. Attach extensions to the auger one at each time while drilling.
The number of extensions to be attached depends on the length which you intend to drill.
When extensions or auger stuck because of the obstacles (rocks and etc), pull out the augers or make the auger spins in inverting direction to drag out the obstacles.
When the obstacles are not possible to be dragged out, change the drilling positions or direction or remove the obstacles before start drilling again.
8. When auger reaches to the depth you need, relief the control lever and stop drilling.
Pull out the auger and extensions, detach the extensions one at each time.
9. Stop the power source after drilling. Detach the extension hoses.
Connect couplers(male and female)which on the earth drill together.
10. Clean dirt which stays on the earth drill, auger and extensions.
