5.3 Mains connection
Mains connection and any extension
cords used must comply with
applicable regulations.
The mains voltage must comply with
the information on the machine
licence plate.
The mains connection must have a
16 A surge-proof fuse.
Only use power cords marked
H07RN-F.
Connections and repairs to the
electrical equipment may only be
carried out by qualified electricians.
5.4 Initial lubrication
The machine must be serviced at all
lubrication points before it is placed
into service!
Failure to comply may cause serious
damage.
(see chapter 8 for lubrication)
5.5 Starting operation
Before starting the machine check
the proper chucking (see chapter 7.2)
Turn on the main switch (D, Fig 1).
You can start the machine with the
green ON-button (Fig 4).
The red button stops the machine.
The speed can be adjusted with the
+/-
buttons.
Use the arrow buttons to reverse the
spindle direction.
Only half maximum speed in reverse
direction.
Fig 4
The RPM will be shown on the display
(Q, Fig 1).
The emergency stop button (O, Fig 1)
stops all machine functions.
Attention:
The machine still has electric power!
Turn emergency stop button clockwise
to reset.
Turn off main switch if the machine is
not in use.
Tapping function:
Push the tapping button, the tapping
mode control light will be on
Choose a low speed for tapping.
Tapping speed is limited to 500rpm.
To reverse direction push the tapping
control buttons on the down feed
handles (B, Fig 1).
6. Machine operation
Warning:
Setup work may only be carried out
after the machine is protected
against accidental starting.
With pressed emergency stop
button.
Never place your fingers in a position
where they could contact any rotating
tool, chuck or cutting chips.
Remove cutting chips with the aid of
an appropriate chip hook when the
machine is at a standstill only.
Never stop the rotating chuck or tool
with your hands.
Always close the chuck guard before
you start the machine.
Secure work piece to the table with
clamps or a vice to prevent rotating
with the drill bit.
When using a vice, always fasten it to
the table.
Check the save clamping of the work
piece, chuck and tools before starting
the machine.
Never do any works “freehand” (hand-
holding the work piece rather than
supporting it on the table).
Support long work pieces with helping
roller stands.
Always adjust the depth stop to
prevent drilling into the table or into
the workholding device.
Feed a drill bit into the material with
only enough force to allow the drill bit
to work.
Feeding too slowly may cause burning
of the work piece or tool. Feeding too
quickly may cause the motor to stop
and/or the drill bit to break.
Do not use wire wheels or grinding
wheels on this machine.
Never cut magnesium-
high danger to fire!
Measurements and adjustments may
be carried out when the machine is at
a standstill only.
In case of danger push the
emergency stop button.
6.1 Spindle speeds selection
The correct spindle speed depends on
the type of machining, the cutting
diameter, the material to be machined
and the cutting tool.
These are recommended max. speeds
for a 10mm high speed steel (HSS)
tool (e.g. drill bit).
Aluminium, brass
1500 RPM
Cast iron
1000 RPM
Mild steel
800 RPM
High carbon steel
600 RPM
Stainless steel
300 RPM
If a carbide (HM) tool is used about 5
times higher speeds can be chosen.
Generally speaking:
the larger in relation the cutting
diameter, the smaller the possible
RPM.
For example:
Milling mild steel with an end mill of
20mm allows a speed of:
400 RPM max.
with HSS tool
2000 RPM max.
with carbide tool
Note:
Choose a low speed for tapping.
Tapping speed is limited to 500rpm.
7. Setup and adjustments
Warning:
Setup and adjustment work may
only be carried out after the
machine is protected against
accidental starting.
Push the emergency stop button
and disconnect from the power
source!
7.1 Arbour replacement
Remove the draw bar cover (R, Fig 1).
Loosen the draw bar with a wrench.
Loosen the drawbar 2 to max 3 full
turns.
