| Automatic Feeding System |
ＥＨＡＣ-８０Ａw |
|
|
| ■ Automatic Feeding System for Core Drill.Artistic performance is installed in CPU circuit |
 |
| ■ Simple and compact Automatic Feeding System only installed high frequency
of usage function. |
| ■ Installed reinforced steel sensor function.It enables not to cut reinforcing
steel in case of small diameter drilling targeting earthquake strengthening.When
the reinforcing steel detected, Core Drill automatically stop using built-in
“Reinforcing steel detection software” |
| ■ 13 Steps of drill load settingLoad setting is possible up to 21A depend on Core Drill and working situation. |
| ■ Setting value of automatic stop function after complete drilling is adjustable.

| ■ Description of control panel |
|
1 Set the drill mode |
|
|
When the power supply cord is plug to the power supply, digital display indicates current drill mode “CC” or “FC”.
If the drill mode needs to be changed, push the “Clutch button” and “Auto Stop button” more than 2 seconds at one time, then you releace your hands when the display changed. |
|
|
2 Start initial drilling around 5mm by manual. |
|
|
Hold down “Drill button” more than 0.2 seconds to start drilling.
Hold the feeding handle and push the “Clutch button” to release the clutch, then start cutting by feeding handle. |
|
|
3 Change manual cutting to automatic cutting. |
|
|
To start automatic cutting, push the “Clutch button”, after that push the
“Feed button”. |
|
|
4 Set the motor load of Core Drill. |
|
|
Change the display current value pushing the “Drilling Load Setting button”
The current value has to be adjusted depend on Core Drill load condition. For example, sound of motor, rotation speed, feeding speed, etc. |
|
|
5 Set automatic stop function.（If you need） |
|
|
If automatic stop function work, drilling will automatically stop after penetrating
Automatic stop function can be set and cancel by pushing “Automatic Stop button”. |
|
|
6 If you would like to stop drilling on the way, push the “Drill button” |
|
7 Hold the feeding handle and push the “Clutch button”, clutch will be
released. You need to move the Drill Head by feeding handle and taking
out drilled core. You can finish the drilling. |
| Reinforcing steel sensor function |
■ Principle of reinforcing steel sensor function
It needs a practice to detect the reinforcing steel in a concrete by hand feeling.
In case of drilling through hole from １m to ２m, the reinforcing steel at core drill side can be detected by Reinforcing Steel Scaning Machine. So we don’t need to care about cutting of the reinforcing steel. However there is a possibility to cut reinforcing steel which is not detected reinforcing steel by Reinforcing Steel Scaning Machine and backside of material.
So we developed “Reinforcing Steel Detection Software” to prevent from cutting reinforcing steel by mistake.
“Reinforcing Steel Detection Software” is always monitoring drilling speed of core bit in order to judge whether the reinforcing steel exist or not in a concreat. If the reinforcing steel is grinded during drilling, the software makes Core Drill stop instantly. So reinforcing steel isn’t cut.

Drilling using “Reinforced Sensor Mode” |
| ■ Instructions and directions for use of “Reinforced Sensor Function”. |
|
1 |
Do not use except drilling for earthquake strengthening.
“Reinforced Sensor Mode” has a possibility to cut electric ductwork, telephone line ductwork, water pipe, gas pipe, regin ductwork, steel wire and, etc. |
|
2 |
Use Core Bit diameater more than 25mm less than 77mm(3”)
If improper Core Bit is used, there is a possibility that Core Drill doesn’t stop after Core Bit contact to reinforcing steel. |
|
3 |
Do not use worn Core Bit
The cutting edge of Core Bit is like a sensor of “Reinforcing Steel Detection Software”. If worn Core Bit is used, detection performance will be low. There is a possibility that Core Drill doesn’t stop after Core Bit contact to reinforcing steel. |
|
4 |
Even if Automatic Feeding System is used, there is a possibility to cut
reinforcing steel depending on a Core Drill condition and working site
situation. So during Drilling, do not get away from Core Drill and check
the sound of drilling and change of water color. |
