Operation - Scheppach DP18VARIO Originalbetriebsanleitung

Now insert the drill chuck (12) including the cone
into the spindle. Check that it is tight.
Note: To protect against corrosion all bare parts are
greased. Before placing the drill chuck (12) on the
spindle, both parts must be made completely free of
grease with an environmentally friendly solvent, so
that optimal power transmission is guaranteed.
Setting up the machine
Prior to starting the machine, the drill must be
mounted on a solid surface. Therefore, use the two
mounting holes in the base plate. Make sure that the
machine is freely accessible for operation and for ad-
justment and maintenance work.
Note: The fastening screws may only be tightened
sufficiently that the base plate is not distorted or de-
formed. Risk of breakage in case of heavy loads.
Pay attention prior to commissioning
Make sure that the voltage of the mains connection
matches the type plate. Only connect the machine to
a socket with a properly installed protective contact.
The drilling machine is equipped with a zero-voltage
release, which protects the operator against uninten-
tional restart after a voltage drop. In this case the ma-
chine must be switched on again.

9. Operation

General, fig. 14
To switch on, press the green on switch "I" (23), the
machine starts. To switch off, press the red on switch
"O" (24), the machine switches off.
Ensure that you do not overload the device.
If the engine noise drops during operation, the engine
is loaded too heavily.
Do not stress the device to the extent that engine is
brought to a stop. Always stand in front of the ma-
chine during operation.
Insert tool into drill chuck, fig. 1
When replacing, ensure that the mains plug is pulled
out. Only cylindrical tools with the specified maxi-
mum shaft diameter may be clamped in the chuck
(12). Use only faultless and sharp tools. Do not use
tools that are damaged on the shaft or that are oth-
erwise deformed or damaged. For your own safety,
only use accessories and additional equipment that
are indicated in the operating manual or have been
recommended or indicated by the manufacturer. If the
bench drilling machine blocks, switch off the machine
and go back to the starting position with the drill.
Handling the quick-action drill chuck
The bench drilling machine is equipped with a quick-
action drill chuck.

The tool can be changed without the aid of an addi-
tional chuck key, by inserting the tool into the quick-
action drill chuck and by tightening it by hand.
Using tools with a conical shaft, fig. 15
The bench drilling machine is equipped with a drilling
spindle cone. To use tools with a conical shaft (MK2),
proceed as follows:
• Bring the chuck to the lower position.
• Drive out the conical shaft with the supplied taper
key (B), taking care that the tool cannot fall onto
the ground.
• Push the new tool with the conical shaft abruptly
into the drilling spindle cone and check that the tool
is tightly fit.
Speed adjustment, fig. 1
The speed of the machine can be continuously ad-
justed.
Attention!
• The speed may only be changed when the en-
gine is running.
• Do not move the speed adjustment lever (6)
suddenly, set the speed slowly and evenly
while the machine is idling.
• Make sure that the machine can run freely (re-
move workpieces, drills, etc.).
The speed can be continuously adjusted using the
speed adjustment lever (6). The defined speed is
shown in turns per minute on the digital display (8).
Attention! Never let the drill run with the V-belt cover
open. Always pull the mains plug before opening the
cover. Never reach into running V-belts.
Drilling depth stop, fig. 16
The drilling spindle has a rotatable scale ring (26)
for setting the drilling depth. Only set up work while
stopped.
• Press the drill spindle down until the drill tip lies on
the workpiece.
• Loosen the clamping screw (25) and turn the scale
ring (26) forward to the stop.
• Turn the scale ring (26) back to the desired drilling
depth and fix it with the clamping screw (25).
Attention! When setting the drilling depth of a cy-
lindrical hole, you must add the length of the drill tip.
Adjust the inclination of the drilling table,
fig. 1/17
• Loosen the hexagon screw (27) under the drilling
table (4).
• Set the drilling table (4) to the desired angle.
• Tighten the coach bolt (27) again to fix the drilling
table (4) in this position.
