Switching the Drill Motor On and Off
The drill motor can only be switched on when the magnet
is activated.
To turn the drill motor on, press the green button
motor switch.
To turn the drill motor off, press the red button
motor switch.
Re-Setting the Machine
If the power is interrupted during use, or if at any point the
magnetic seal is broken, the machine must be reset.
1. Switch off the drill motor first, and then the magnet.
2. Ensure that the work area is clean.
3. Switch on the power/ magnet.
Overload Protection (Fig. I)
The D WALT magnetic drill is fitted with an overload
e
protection feature to prevent damage to the motor if
excessive loads are applied during operation.
The LED indicator light 14 will flash as a warning that
excessive load is being applied, if this happens reduce the
pressure being applied until the light is constant green. If
pressure is not reduced the overload will activate cutting
power, at which point the LED will be a solid red. If this
occurs run the unit at no load for several seconds to allow
the motor to cool before resuming the drilling operation.
Drilling Hole (Fig. I)
1. Always apply an appropriate cutting fluid / coolant on
the cutting area.
2. Lower the guard so that it screens the surface to
be drilled.
3. Make sure the drill point or cutter pilot is properly
installed over the spot to be drilled.
4. Press green button on the motor switch to the
3
start motor.
5. Slowly feed the accessory into the workpiece using the
feed handle.
6. At the start of the cut, apply light pressure to allow the
accessory to perform the initial groove.
7. Continue applying sufficient pressure to achieve a
smooth progressive cut. Do not force.
NoTE: The LED indicator light
indicate too much pressure is being applied, if this
happens reduce the pressure being applied until the
light changes to a constant (green).
8. The pressure exerted on the handle is too high if the
stand comes loose from the work surface.
9. Take extra care when the accessory is about to break
through the surface to prevent splintering.
10. Always switch off the motor, the magnet and the
power, in that particular order, when work is finished
and before unplugging.

Drilling with Annular Cutters

WARNING: Do not touch the cutter or the parts close
to the cutter immediately after operation, as they
may be extremely hot and cause burns to the skin.
Ensure nobody is in the work area where the metal
core is ejected.
1. Annular cutters only cut material at the periphery of the
hole, rather than converting the entire hole to shavings.
As a result the energy required to make a hole is lower
than for a twist drill.
2. When drilling with an annular cutter, it is not necessary
to drill a pilot hole.
Drilling Conditions
The ease with which material can be drilled is dependent
on several factors including tensile strength and abrasion
resistance. Whilst hardness and /or strength is the usual
criterion, wide variations in machine ability can exist among
material showing similar physical properties. The drilling
conditions are dependent on requirements for tool life
and surface finish. These conditions are further restricted
by the rigidity of the tool and the workpiece, lubrication
and machine power available. The harder the material the
lower the cutting speed. Some materials of low hardness
contain abrasive substances leading to rapid cutting edge
wear at high speeds. Feed rates are governed by rigidity of
set-up, volume of material to be removed, surface finish and
available machine power.
MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can cause injury.
Your D WALT power tool has been designed to operate
e
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper
tool care and regular cleaning.
Pop-Off Brushes
The motor will be automatically shutoff indicating that the
carbon brushes are nearly worn out and that the tool needs
servicing. The carbon brushes are not user-serviceable. Take
the tool to an authorised D WALT repair agent.

Lubrication (Fig. A, K)
Lubrication in Horizontal Applications
(Fig. A)
1. Adjust the fluid flow as required using the flow
regulator 13 .
2. Add more cutting fluid if the shavings become blue.
Lubrication in Vertical and Overhead
Applications
Dip the cutter in cutting paste or apply an appropriate spray.
