4. DRILLING
4.1) Preparing the drilling machine
Remove drilling machine, detachable guard and auger from storage case.
Stop the engine before removing the auger
4.1.1) Fitting and removing the auger
(See Fig. 1)
Select the auger suitable for the work to be done:
– Turn the emergency lever (09) and fully insert the auger.
– Release the emergency lever (09).
– Manually rotate the auger until a click is heard, indicating automatic locking.
To remove the auger: turn the emergency lever, manually rotate and remove the auger from
the spindle.
4.1.2) Assemble the guard PRM-U
(See Fig. 1)
To fit the detachable guard PRM-U (19), complete with end piece, proceed as follows:
– Unscrew the guard knob (20) from each shaft (22).
– Slide the shafts (22) into the brass bushes on the detachable guard (19): until they protrude
sufficiently, to enable the guard knobs (20) to be fitted.
Tighten the guard knobs by hand.
The SD-10E machine is supplied complete with
TPM 200-26
end piece; should it need to be replaced,
simply unscrew it by hand and screw on the new end piece suitable for the centreing required.
Slide the guard bushes onto each shaft and screw a guard knob onto the shaft.
4.1.3) Setting the hole depth
(See Fig. 1)
Open the lever and loosen the adjuster (24).
Position the adjuster to the desired depth on the gradu-
ated scale.
Tighten the adjuster and close the lever.
During the drilling operation, the adjuster butts against
the detachable guard at the preset hole depth to prevent
any further travel of the auger.
4.1.4) Connecting the power supply
– Connect the electric plug (02), see Fig. 6.
– Press the automatic switch (03)
(position "I")
.
CAUTION: the automatic switch (03) is equipped with protection against motor over-
heating and with an underpower relay; should the motor overheat or there is a fall in voltage
below the relay cut-out setting, the switch will move into the "0" position. At this stage, if the
conditions are correct, the switch will have to be re-set manually.
