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. 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
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.
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 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 injury, turn unit off and
disconnect tool from power source before installing and
removing accessories, 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 over a
E
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
LUBRICATION IN HORIZONTAL APPLICATIONS (FIG. 4)
1. Adjust the fluid flow as required using the flow regulator (M).
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.
LUBRICATING THE FEED TRAVEL (FIG. 11)
The feed travel should be lubricated
periodically with grease to ensure
smooth operation.
1. Raise the motor unit to the highest
position possible.
2. Lubricate the dove-tail guide way
(DD) at both sides.
3. Lubricate the gear rack (EE).
