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

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
sure the switch is in the OFF position.
An accidental start-up can cause injury.
Your D WALT power tool has been designed to
E
operate 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 shut off when the
carbon brushes are nearly worn out and the tool
needs servicing. The carbon brushes are not user-
serviceable. Take the tool to an authorised D
repair agent.
Lubrication
IN HORIZONTAL APPLICATIONS (FIG. 1)
• Adjust the fluid flow as required using the flow
regulator (m).
• Add more cutting fluid if the shavings become
blue.
VERTICAL AND OVERHEAD APPLICATIONS
Dip the cutter in cutting paste or apply an
appropriate spray.
LUBRICATING THE FEED TRAVEL (FIG. 9)
The feed travel should be lubricated periodically with
grease to ensure smooth operation.
• Raise the motor unit to the highest position
possible.
• Lubricate the dove-tail guide way (dd) at both
sides.
• Lubricate the gear rack (ee).
After repeated use, the gear rack may become
loose. If necessary, adjust the 5 self-locking set
screws at the left side. Tighten screws in series until
the gear rack moves freely in the dove-tail guide but
does not allow the motor to wobble.
Cleaning
WARNING: Blow dirt and dust out of
the main housing with dry air as often as
dirt is seen collecting in and around the
air vents. Wear approved eye protection
and approved dust mask when
performing this procedure.
WARNING: Never use solvents or
other harsh chemicals for cleaning the
non-metallic parts of the tool. These
chemicals may weaken the materials
used in these parts. Use a cloth
dampened only with water and mild
soap. Never let any liquid get inside the
tool; never immerse any part of the tool
into a liquid.
