MAGNETIC DRILL SAFETY
INSTRUCTIONS
•
Always inspect the whole unit before use.
•
Regular maintenance is essential - check nuts,
screws etc. for tightness before each use.
•
Check cable and plug for damage.
•
Never use blunt or damaged cutters.
•
Never use a larger diameter cutter than
specified for the machine.
•
Always use the saf e ty guards where
fitted and ensure they are operating correctly.
•
Always wear goggles and gloves
•
Remove rings, watches, ties etc. that could
tangle in the moving parts.
•
Secure the unit with the safety strap before
drilling.
•
The machine is for use on steel from 6 mm
thick with no air gap between the magnet core
and the workpiece. Curvature, paint, and
surface irregularities create an air gap. Keep
the air gap to a minimum.
•
Keep the magnet and workpiece clean & free of
debris and swarf.
•
Do not start the motor before ensuring that
the magnetic stand is clamped firmly to the
workpiece.
•
Only use a general oil-based m e t a l cutting
oil.
•
While drilling horizontally or overhead, use a
cutting paste or an appropriate coolant spray.
•
Always disconnect from the power source
before c hangi ng c u t t e r o r working o n the
machine.
•
In the event of a jammed cutter, disconnect
from the power supply and free the jam before
reconnecting the tool.
•
On swivel machines, ensure that the swivel
base is locked in the required position.
•
Do not attempt to change speed while
the drill is running.
•
Only use accessories recommended by the
manufacturer.
•
Never lift or carry the unit by the power cord,
always use the handle.
•
Never modify the tool in any way.
MAINTENANCE
INSTRUCTIONS
•
Occasionally apply a few drops of oil to the
rack toothing.
•
The bearings of the feed shaft are self-
lubricating and must not be greased
•
Grease the sliding surface of the carriage
with MOLYCOTE grease.
•
When not in use or being transported the
unit should be kept in the case supplied.

dirt.
•
Parts that are worn or damaged should be
r e p l a c e d immediately with g e n u i n e
manufacturer
’
s replacements.
•
Ensure all cutting edges are sharp when in
operation. Using blunt cutting tools may lead
to an overload of the motor.
•
Aft er e v e r y 3 0 m i n u t e s r u nn i n g, i t is
recommended that the machine is laid on its
side to permit grease to run across the gear
train.
•
After repeated use, the cradle may become
loose. This is remedied by adjusting the tension
screws on the side of the body. Put 2.5mm hex
wrench into head of cradle retaining nuts,
using 8mm Spanner undo the locking nuts anti-
clockwise, holding the hex wrench without
moving grub screws.
Using the hex wrench gently tighten screws in
series until the cradle moves freely in the slide
but does not allow the motor to wobble.
When adjustm ent is c o m plete re -tighten
locking nuts clockwise, ensuring the grub
screws do not move from their new positions.
IMPORTANT!
–
TO PREVENT DAMAGE TO THE CIRCUITRY, NEVER USE ELECTROMAGNETIC DRILLING MACHINES AND
WELDING EQUIPMENT ON THE SAME W O R K P I E C E SIMULTANEOUSLY.
