ENGLISH

To turn the power off, press the power/magnet switch to the off position.

TURNING 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 (c) on the motor switch.

To turn the drill motor off, press the red button (b) on the 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.Turn off the drill motor first, and then the power/magnet.

2.Ensure that the work area is clean.

3.Turn on the power/magnet.

Drilling a Hole (fig. 1)

1.Always apply an appropriate cutting fluid/coolant on the cutting area.

2.Lower the guard (j) 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 (c) on the motor switch to the start motor.

5.Slowly feed the accessory into the workpiece using the feed handle (f).

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 (n) will flash (red) to indicate too much pressure is being applied, if this happens reduce the pressure being applied until the light changes to a constant (green).

8.Take extra care when the accessory is about to break through the surface to prevent splintering.

9.Always turn off the motor, the magnet and the power, in that particular order, when work is finished and before unplugging.

OVERLOAD PROTECTION

The DEWALT magnetic drill is fitted with an overload protection feature to prevent damage to the motor if excessive loads are applied during operation.

The LED indicator light (n) will flash as a warning that excessive load is being applied, if this happens reduce the pressure being applied until the light

changes to a constant green. If pressure is not reduced the overload protection will activate by cutting power, at which point the LED will be a constant red. To reset the tool from this state, run the unit at no load for several seconds. This allows the motor to cool before resuming the drilling operation.

Drilling with Annular Cutters

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.

When drilling with an annular cutter, it is not necessary to drill a pilot hole.

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.

Drilling Conditions

The ease with which material can be drilled depends on several factors including tensile strength and abrasion resistance. Whilst hardness and/or strength is the usual criterion, wide variations in machineability 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

Your DEWALT power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.

WARNING: To reduce the risk of injury, turn unit off and disconnect machine from power source before installing and removing accessories, before adjusting or changing

set-ups or when making repairs. Be
