- Ensure that the securing strap is guided to be taut
in position.
- Check that the strap connection is secure.
The securing strap does not replace the
magnetic force of the magnetic drill stand: it is
simply used to secure against falling in the event of
a magnet malfunction.
To loosen the securing strap:
Caution: the tension is released in sudden
bursts! To loosen the securing strap, open the
ratchet fully and simultaneously use your finger to
pull the locking strap (b) upward.
7.2 Cooling Lubrication Unit for Core Drilling
The tool life depends on the lubrication. Lubricating
the inside of the core drill bit with high-performance
cutting oils is essential for core drilling.
To fill with oil, remove the container (4) from
the magnetic drill stand.
Fill the container with high-performance cutting oil
(4) and close the screw cap. Switch the lubrication
on or off at the supply cock (3).
For work carried out on vertical and overhanging
surfaces or overhead surfaces (and when storing
the unit in the case), the container (4) must be
emptied or removed to prevent liquid from escaping
(otherwise there is a risk of cutting oil entering the
motor and causing a short-circuit). When carrying
out this type of task, spray the inside of the cutting
edge tool before drilling with universal cutting spray
(see chapter 10. Accessories). Repeat the process
several times for larger drilling depths.
7.3 Setting the gear
Two-speed gear box:
Do not activate the thumbwheel (10) until the
motor has completely stopped.
Select the required gear by turning the thumbwheel
(10). If necessary, you can aid the switching
procedure by turning the drill spindle slightly.
Recommended setting:
• • = 2nd gear, high speed: Drilling in steel with a bit
diameter of up to approx. 20 mm
• = 1st gear, high torque: Drilling in steel with a bit
diameter larger than approx. 20 mm
7.4 Activating/deactivating the magnet
When deactivated, the magnet loses its
holding power.
To activate the magnet: turn the switch lever (25) to
"ON". Turn the shaft (23) with the ratchet lever (26).
To deactivate the magnet: turn the switch lever
(25) to "OFF". Turn the shaft (23) with the ratchet
lever (26).
If the magnetic drill stand is not placed on
metal, you will feel resistance while turning the
shaft (23). Do not try to overcome this resistance
and never try to continue turning the shaft!
Otherwise you will damage the steering gear.
The resistance is eliminated once the magnetic drill
stand is placed on metal.
The magnet is either fully activated or
deactivated once the stop is reached. Never
continue to turn the shaft! Otherwise you will
damage the steering gear. You should only work
with the tool when the magnet is fully activated.
Note: If you cannot use the ratchet due to restricted
working conditions, then you can insert an Allen key
in the shaft hexagon socket (23) to turn the shaft
(adjust the switch lever (25) accordingly).
The magnet's holding power appears on the
display (24):
Fully red = Holding power Off
Fully green = Holding power On
Note: If the display (24) is switching from red to
green (see diagram, page 2), a small amount of
holding power is available, which can be used when
fastening and aligning the magnetic drill stand.
7.5 Switching on/off the driving unit
Do not switch on the driving unit until the
magnet is fully activated and securely
attached to the base.
Switching on: Move switch (8) to "I" position.
Switching off: Move switch (8) to "O" position. Wait
until the driving unit has come to a complete
standstill.
7.6 Mounting on the Workpiece
To permit the magnetic drill stand to adhere
properly to material that is to be drilled, the surface
must be clean and smooth. Loose rust, dirt or
grease must be removed before mounting the
magnetic drill stand; any welding beads or surface
irregularities must be smoothened. Clean the
magnet block as well (1) if necessary.
Note: If the display (24) is switching from red to
green (see diagram, page 2), a small amount of
holding power is available, which can be used when
fastening and aligning the magnetic drill stand.
Once the magnet has been fully activated, shake
the handle (2) of the magnetic drill stand firmly to
ensure that the stand adheres perfectly to the
material. If this is not the case, then check the
condition of the surface of the material and the
bottom of the magnet block. Clean as necessary
and try again.
Use on thin steel
The unit adheres best to low-carbon steel that is at
least 15 mm thick.
For drilling a hole into thin steel, a steel plate
measuring at least 100 x 200 x 15 mm can be
secured under the material at the place where the
magnetic stand is to be positioned.
Non-ferrous metals
To drill a hole in non-ferrous metal, the steel plate
should be secured on the surface of the material
and the magnetic drill stand then placed on the steel
plate.
